+/**
+   \mainpage CMSIS DSP Software Library
+   *
+   * <b>Introduction</b>
+   *
+   * This user manual describes the CMSIS DSP software library, 
+   * a suite of common signal processing functions for use on Cortex-M processor based devices.
+   *
+   * The library is divided into a number of modules each covering a specific category:
+   * - Basic math functions
+   * - Fast math functions
+   * - Complex math functions
+   * - Filters
+   * - Matrix functions
+   * - Transforms
+   * - Motor control functions
+   * - Statistical functions
+   * - Support functions
+   * - Interpolation functions
+   *
+   * The library has separate functions for operating on 8-bit integers, 16-bit integers,
+   * 32-bit integer and 32-bit floating-point values. 
+   *
+   * <b>Processor Support</b>
+   *
+   * The library is completely written in C and is fully CMSIS compliant. 
+   * High performance is achieved through maximum use of Cortex-M4 intrinsics. 
+   *
+   * The supplied library source code also builds and runs on the Cortex-M3 and Cortex-M0 processor,
+   * with the DSP intrinsics being emulated through software. 
+   *
+   *
+   * <b>Toolchain Support</b>
+   *
+   * The library has been developed and tested with MDK-ARM version 4.21. 
+   * The library is being tested in GCC and IAR toolchains and updates on this activity will be made available shortly.
+   *
+   * <b>Using the Library</b>
+   *
+   * The library installer contains prebuilt versions of the libraries in the <code>Lib</code> folder.
+   * - arm_cortexM4lf_math.lib (Little endian and Floating Point Unit on Cortex-M4)
+   * - arm_cortexM4bf_math.lib (Big endian and Floating Point Unit on Cortex-M4)
+   * - arm_cortexM4l_math.lib (Little endian on Cortex-M4)
+   * - arm_cortexM4b_math.lib (Big endian on Cortex-M4)
+   * - arm_cortexM3l_math.lib (Little endian on Cortex-M3)
+   * - arm_cortexM3b_math.lib (Big endian on Cortex-M3)
+   * - arm_cortexM0l_math.lib (Little endian on Cortex-M0)
+   * - arm_cortexM0b_math.lib (Big endian on Cortex-M3)
+   *
+   * The library functions are declared in the public file <code>arm_math.h</code> which is placed in the <code>Include</code> folder.
+   * Simply include this file and link the appropriate library in the application and begin calling the library functions. The Library supports single 
+   * public header file <code> arm_math.h</code> for Cortex-M4/M3/M0 with little endian and big endian. Same header file will be used for floating point unit(FPU) variants. 
+   * Define the appropriate pre processor MACRO ARM_MATH_CM4 or  ARM_MATH_CM3 or 
+   * ARM_MATH_CM0 depending on the target processor in the application.
+   *
+   * <b>Examples</b>
+   *
+   * The library ships with a number of examples which demonstrate how to use the library functions.
+   *
+   * <b>Building the Library</b>
+   *
+   * The library installer contains project files to re build libraries on MDK Tool chain in the <code>CMSIS\DSP_Lib\Source\ARM</code> folder.
+   * - arm_cortexM0b_math.uvproj
+   * - arm_cortexM0l_math.uvproj
+   * - arm_cortexM3b_math.uvproj
+   * - arm_cortexM3l_math.uvproj  
+   * - arm_cortexM4b_math.uvproj
+   * - arm_cortexM4l_math.uvproj
+   * - arm_cortexM4bf_math.uvproj
+   * - arm_cortexM4lf_math.uvproj
+   *
+   * Each library project have differant pre-processor macros.
+   *
+   * <b>ARM_MATH_CMx:</b>
+   * Define macro ARM_MATH_CM4 for building the library on Cortex-M4 target, ARM_MATH_CM3 for building library on Cortex-M3 target
+   * and ARM_MATH_CM0 for building library on cortex-M0 target.
+   *
+   * <b>ARM_MATH_BIG_ENDIAN:</b>
+   * Define macro ARM_MATH_BIG_ENDIAN to build the library for big endian targets. By default library builds for little endian targets.
+   *
+   * <b>ARM_MATH_MATRIX_CHECK:</b>
+   * Define macro for checking on the input and output sizes of matrices
+   *
+   * <b>ARM_MATH_ROUNDING:</b>
+   * Define macro for rounding on support functions
+   *
+   * <b>__FPU_PRESENT:</b>
+   * Initialize macro __FPU_PRESENT = 1 when building on FPU supported Targets. Enable this macro for M4bf and M4lf libraries 
+   *
+   *
+   * The project can be built by opening the appropriate project in MDK-ARM 4.21 chain and defining the optional pre processor MACROs detailed above.

+ * to the number of complex values; the array contains twice this number of
+ * real values.

+
+/**
+ * @defgroup groupFilters Filtering Functions
+ */
+
+/**
+ * @defgroup groupMatrix Matrix Functions
+ *
+ * This set of functions provides basic matrix math operations.
+ * The functions operate on matrix data structures.  For example,
+ * the type
+ * definition for the floating-point matrix structure is shown
+ * below:
+ * <pre>
+ *     typedef struct
+ *     {
+ *       uint16_t numRows;     // number of rows of the matrix.
+ *       uint16_t numCols;     // number of columns of the matrix.
+ *       float32_t *pData;     // points to the data of the matrix.
+ *     } arm_matrix_instance_f32;
+ * </pre>
+ * There are similar definitions for Q15 and Q31 data types.
+ *
+ * The structure specifies the size of the matrix and then points to
+ * an array of data.  The array is of size <code>numRows X numCols</code>
+ * and the values are arranged in row order.  That is, the
+ * matrix element (i, j) is stored at:
+ * <pre>
+ *     pData[i*numCols + j]
+ * </pre>
+ *
+ * \par Init Functions
+ * There is an associated initialization function for each type of matrix
+ * data structure.
+ * The initialization function sets the values of the internal structure fields.
+ * Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
+ * and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types,  respectively.
+ *
+ * \par
+ * Use of the initialization function is optional. However, if initialization function is used
+ * then the instance structure cannot be placed into a const data section.
+ * To place the instance structure in a const data
+ * section, manually initialize the data structure.  For example:
+ * <pre>
+ * <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
+ * <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
+ * <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
+ * </pre>
+ * where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
+ * specifies the number of columns, and <code>pData</code> points to the
+ * data array.
+ *
+ * \par Size Checking
+ * By default all of the matrix functions perform size checking on the input and
+ * output matrices.  For example, the matrix addition function verifies that the
+ * two input matrices and the output matrix all have the same number of rows and
+ * columns.  If the size check fails the functions return:
+ * <pre>
+ *     ARM_MATH_SIZE_MISMATCH
+ * </pre>
+ * Otherwise the functions return
+ * <pre>
+ *     ARM_MATH_SUCCESS
+ * </pre>
+ * There is some overhead associated with this matrix size checking.
+ * The matrix size checking is enabled via the #define
+ * <pre>
+ *     ARM_MATH_MATRIX_CHECK
+ * </pre>
+ * within the library project settings.  By default this macro is defined
+ * and size checking is enabled.  By changing the project settings and
+ * undefining this macro size checking is eliminated and the functions
+ * run a bit faster.  With size checking disabled the functions always
+ * return <code>ARM_MATH_SUCCESS</code>.

+   *
+   * A Proportional Integral Derivative (PID) controller is a generic feedback control 
+   * loop mechanism widely used in industrial control systems.
+   * A PID controller is the most commonly used type of feedback controller.
+   *
+   * This set of functions implements (PID) controllers
+   * for Q15, Q31, and floating-point data types.  The functions operate on a single sample
+   * of data and each call to the function returns a single processed value.
+   * <code>S</code> points to an instance of the PID control data structure.  <code>in</code>
+   * is the input sample value. The functions return the output value.
+   *
+   * \par Algorithm:
+   * <pre>
+   *    y[n] = y[n-1] + A0 * x[n] + A1 * x[n-1] + A2 * x[n-2]
+   *    A0 = Kp + Ki + Kd
+   *    A1 = (-Kp ) - (2 * Kd )
+   *    A2 = Kd  </pre>
+   *
+   * \par
+   * where \c Kp is proportional constant, \c Ki is Integral constant and \c Kd is Derivative constant
+   * 
+   * \par 
+   * \image html PID.gif "Proportional Integral Derivative Controller" 
+   *
+   * \par
+   * The PID controller calculates an "error" value as the difference between
+   * the measured output and the reference input.
+   * The controller attempts to minimize the error by adjusting the process control inputs.  
+   * The proportional value determines the reaction to the current error, 
+   * the integral value determines the reaction based on the sum of recent errors, 
+   * and the derivative value determines the reaction based on the rate at which the error has been changing.
+   *
+   * \par Instance Structure 
+   * The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure. 
+   * A separate instance structure must be defined for each PID Controller. 
+   * There are separate instance structure declarations for each of the 3 supported data types. 
+   * 
+   * \par Reset Functions 
+   * There is also an associated reset function for each data type which clears the state array. 
+   *
+   * \par Initialization Functions 
+   * There is also an associated initialization function for each data type. 
+   * The initialization function performs the following operations: 
+   * - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
+   * - Zeros out the values in the state buffer.   
+   * 
+   * \par 
+   * Instance structure cannot be placed into a const data section and it is recommended to use the initialization function. 
+   *
+   * \par Fixed-Point Behavior 
+   * Care must be taken when using the fixed-point versions of the PID Controller functions. 
+   * In particular, the overflow and saturation behavior of the accumulator used in each function must be considered. 
+   * Refer to the function specific documentation below for usage guidelines.

+   *
+   * Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
+   * The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
+   * determines values between the grid points.
+   * Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
+   * Bilinear interpolation is often used in image processing to rescale images.
+   * The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
+   *
+   * <b>Algorithm</b>
+   * \par
+   * The instance structure used by the bilinear interpolation functions describes a two dimensional data table.
+   * For floating-point, the instance structure is defined as:
+   * <pre>
+   *   typedef struct
+   *   {
+   *     uint16_t numRows;
+   *     uint16_t numCols;
+   *     float32_t *pData;
+   * } arm_bilinear_interp_instance_f32;
+   * </pre>
+   *
+   * \par
+   * where <code>numRows</code> specifies the number of rows in the table;
+   * <code>numCols</code> specifies the number of columns in the table;
+   * and <code>pData</code> points to an array of size <code>numRows*numCols</code> values.
+   * The data table <code>pTable</code> is organized in row order and the supplied data values fall on integer indexes.
+   * That is, table element (x,y) is located at <code>pTable[x + y*numCols]</code> where x and y are integers.
+   *
+   * \par
+   * Let <code>(x, y)</code> specify the desired interpolation point.  Then define:
+   * <pre>
+   *     XF = floor(x)
+   *     YF = floor(y)
+   * </pre>
+   * \par
+   * The interpolated output point is computed as:
+   * <pre>
+   *  f(x, y) = f(XF, YF) * (1-(x-XF)) * (1-(y-YF))
+   *           + f(XF+1, YF) * (x-XF)*(1-(y-YF))
+   *           + f(XF, YF+1) * (1-(x-XF))*(y-YF)
+   *           + f(XF+1, YF+1) * (x-XF)*(y-YF)
+   * </pre>
+   * Note that the coordinates (x, y) contain integer and fractional components.  
+   * The integer components specify which portion of the table to use while the
+   * fractional components control the interpolation processor.
+   *
+   * \par
+   * if (x,y) are outside of the table boundary, Bilinear interpolation returns zero output.

+  * @brief   CMSIS Cortex-M4 Device Peripheral Access Layer Header File. 
+  *          This file contains all the peripheral register's definitions, bits 
+  *          definitions and memory mapping for STM32F4xx devices.            
+  *            
+  *          The file is the unique include file that the application programmer
+  *          is using in the C source code, usually in main.c. This file contains:
+  *           - Configuration section that allows to select:
+  *              - The device used in the target application
+  *              - To use or not the peripheral�s drivers in application code(i.e. 
+  *                code will be based on direct access to peripheral�s registers 
+  *                rather than drivers API), this option is controlled by 
+  *                "#define USE_STDPERIPH_DRIVER"
+  *              - To change few application-specific parameters such as the HSE 
+  *                crystal frequency
+  *           - Data structures and the address mapping for all peripherals
+  *           - Peripheral's registers declarations and bits definition
+  *           - Macros to access peripheral�s registers hardware

+  * @brief   This file provides all the LCD Log firmware functions.
+  *          
+  *          The LCD Log module allows to automatically set a header and footer
+  *          on any application using the LCD display and allows to dump user,
+  *          debug and error messages by using the following macros: LCD_ErrLog(),
+  *          LCD_UsrLog() and LCD_DbgLog().
+  *         
+  *          It supports also the scroll feature by embedding an internal software
+  *          cache for display. This feature allows to dump message sequentially
+  *          on the display even if the number of displayed lines is bigger than
+  *          the total number of line allowed by the display.

+  * @version V1.0.1
+  * @date    28-October-2013
+  * @brief   This file provides a set of functions needed to manage an I2C M24LR64 
+  *          EEPROM memory.
+  *          
+  *          =================================================================== 
+  *          Notes:
+  *           - This driver is intended for STM32F4xx families devices only. 
+  *           - The I2C EEPROM memory (M24LR64) is available on separate daughter 
+  *             board ANT7-M24LR-A, which is not provided with the STM32F429I 
+  *             DISCOVERY board.
+  *             To use this driver you have to connect the ANT7-M24LR-A to CN3 
+  *             connector of STM32F429I DISCOVERY board.      
+  *          ===================================================================
+  *              
+  *          It implements a high level communication layer for read and write 
+  *          from/to this memory. The needed STM32F4xx hardware resources (I2C and 
+  *          GPIO) are defined in stm32f429i_discovery.h file, and the initialization is 
+  *          performed in sEE_LowLevel_Init() function declared in stm32f429i_discovery.c 
+  *          file.
+  *          You can easily tailor this driver to any other development board, 
+  *          by just adapting the defines for hardware resources and 
+  *          sEE_LowLevel_Init() function. 
+  *        
+  *          @note In this driver, basic read and write functions (sEE_ReadBuffer() 
+  *                and sEE_WritePage()) use Polling mode to perform the data transfer 
+  *                to/from EEPROM memory.

+  *    These two events are similar: 
+  *     - EV8 means that the data has been written in the data register and is 
+  *       being shifted out.
+  *     - EV8_2 means that the data has been physically shifted out and output 
+  *       on the bus.
+  *     In most cases, using EV8 is sufficient for the application.
+  *     Using EV8_2 leads to a slower communication but ensure more reliable test.
+  *     EV8_2 is also more suitable than EV8 for testing on the last data transmission 
+  *     (before Stop condition generation).

+  *  @note In case the  user software does not guarantee that this event EV7 is

+  *        and BTF flag at the same time (ie. (I2C_EVENT_MASTER_BYTE_RECEIVED | I2C_FLAG_BTF)).
+  *        In this case the communication may be slower.

+ ===============================================================================
+                          I2C State Monitoring Functions
+ ===============================================================================
+  This I2C driver provides three different ways for I2C state monitoring
+  depending on the application requirements and constraints:
+         
+   
+     1. Basic state monitoring (Using I2C_CheckEvent() function)
+     -----------------------------------------------------------
+        It compares the status registers (SR1 and SR2) content to a given event
+        (can be the combination of one or more flags).
+        It returns SUCCESS if the current status includes the given flags 
+        and returns ERROR if one or more flags are missing in the current status.
+
+          - When to use
+             - This function is suitable for most applications as well as for startup 
+               activity since the events are fully described in the product reference 
+               manual (RM0090).
+             - It is also suitable for users who need to define their own events.
+
+          - Limitations
+             - If an error occurs (ie. error flags are set besides to the monitored 
+               flags), the I2C_CheckEvent() function may return SUCCESS despite 
+               the communication hold or corrupted real state. 
+               In this case, it is advised to use error interrupts to monitor 
+               the error events and handle them in the interrupt IRQ handler.
+         
+     Note 
+         For error management, it is advised to use the following functions:
+           - I2C_ITConfig() to configure and enable the error interrupts (I2C_IT_ERR).
+           - I2Cx_ER_IRQHandler() which is called when the error interrupt occurs.
+             Where x is the peripheral instance (I2C1, I2C2 ...)
+           - I2C_GetFlagStatus() or I2C_GetITStatus()  to be called into the 
+             I2Cx_ER_IRQHandler() function in order to determine which error occurred.
+           - I2C_ClearFlag() or I2C_ClearITPendingBit() and/or I2C_SoftwareResetCmd() 
+             and/or I2C_GenerateStop() in order to clear the error flag and source 
+             and return to correct  communication status.
+             
+ 
+     2. Advanced state monitoring (Using the function I2C_GetLastEvent())
+     -------------------------------------------------------------------- 
+        Using the function I2C_GetLastEvent() which returns the image of both status 
+        registers in a single word (uint32_t) (Status Register 2 value is shifted left 
+        by 16 bits and concatenated to Status Register 1).
+
+          - When to use
+             - This function is suitable for the same applications above but it 
+               allows to overcome the mentioned limitation of I2C_GetFlagStatus() 
+               function.
+             - The returned value could be compared to events already defined in 
+               this file or to custom values defined by user.
+               This function is suitable when multiple flags are monitored at the 
+               same time.
+             - At the opposite of I2C_CheckEvent() function, this function allows 
+               user to choose when an event is accepted (when all events flags are 
+               set and no other flags are set or just when the needed flags are set 
+               like I2C_CheckEvent() function.
+
+          - Limitations
+             - User may need to define his own events.
+             - Same remark concerning the error management is applicable for this 
+               function if user decides to check only regular communication flags 
+               (and ignores error flags).
+      
+ 
+     3. Flag-based state monitoring (Using the function I2C_GetFlagStatus())
+     -----------------------------------------------------------------------
+     
+      Using the function I2C_GetFlagStatus() which simply returns the status of 
+      one single flag (ie. I2C_FLAG_RXNE ...). 
+
+          - When to use
+             - This function could be used for specific applications or in debug 
+               phase.
+             - It is suitable when only one flag checking is needed (most I2C 
+               events are monitored through multiple flags).
+          - Limitations: 
+             - When calling this function, the Status register is accessed. 
+               Some flags are cleared when the status register is accessed. 
+               So checking the status of one Flag, may clear other ones.
+             - Function may need to be called twice or more in order to monitor 
+               one single event.

+  *          ===================================================================      
+  * 
+  *            This section provide functions allowing to configure the NVIC interrupts (IRQ).
+  *            The Cortex-M4 exceptions are managed by CMSIS functions.
+  *
+  *            1. Configure the NVIC Priority Grouping using NVIC_PriorityGroupConfig()
+  *                function according to the following table.
+ 
+  *  The table below gives the allowed values of the pre-emption priority and subpriority according
+  *  to the Priority Grouping configuration performed by NVIC_PriorityGroupConfig function
+  *    ==========================================================================================================================

+  *    --------------------------------------------------------------------------------------------------------------------------
+  *     NVIC_PriorityGroup_1  |                0-1                |            0-7              | 1 bits for pre-emption priority

+  *     NVIC_PriorityGroup_3  |                0-7                |            0-1              | 3 bits for pre-emption priority
+  *                           |                                   |                             | 1 bits for subpriority
+  *    --------------------------------------------------------------------------------------------------------------------------

+  *    ==========================================================================================================================     
+  *
+  *            2. Enable and Configure the priority of the selected IRQ Channels using NVIC_Init()  
+  *
+  * @note  When the NVIC_PriorityGroup_0 is selected, IRQ pre-emption is no more possible. 
+  *        The pending IRQ priority will be managed only by the subpriority.
+  *
+  * @note  IRQ priority order (sorted by highest to lowest priority):
+  *         - Lowest pre-emption priority
+  *         - Lowest subpriority
+  *         - Lowest hardware priority (IRQ number)

+ ===============================================================================  
+    [..] This section provides functions allowing to configure the DMA for ADC 
+         regular channels.
+         Since converted regular channel values are stored into a unique data 
+         register, it is useful to use DMA for conversion of more than one regular 
+         channel. This avoids the loss of the data already stored in the ADC 
+         Data register.   
+         When the DMA mode is enabled (using the ADC_DMACmd() function), after each
+         conversion of a regular channel, a DMA request is generated.
+    [..] Depending on the "DMA disable selection for Independent ADC mode" 
+         configuration (using the ADC_DMARequestAfterLastTransferCmd() function), 
+         at the end of the last DMA transfer, two possibilities are allowed:
+      (+) No new DMA request is issued to the DMA controller (feature DISABLED) 
+      (+) Requests can continue to be generated (feature ENABLED).  
+    [..] Depending on the "DMA disable selection for multi ADC mode" configuration 
+         (using the void ADC_MultiModeDMARequestAfterLastTransferCmd() function),

+ ===============================================================================
+            ##### Interrupts and flags management functions #####
+ ===============================================================================  
+
+    [..] This section provides functions allowing to configure the ADC Interrupts 
+         and to get the status and clear flags and Interrupts pending bits.
+  
+    [..] Each ADC provides 4 Interrupts sources and 6 Flags which can be divided
+        into 3 groups:
+  
+  *** Flags and Interrupts for ADC regular channels ***
+  =====================================================
+    [..]
+      (+) Flags :
+        (##) ADC_FLAG_OVR : Overrun detection when regular converted data are lost
+
+        (##) ADC_FLAG_EOC : Regular channel end of conversion ==> to indicate 
+             (depending on EOCS bit, managed by ADC_EOCOnEachRegularChannelCmd() )
+             the end of:
+             (+++) a regular CHANNEL conversion 
+             (+++) sequence of regular GROUP conversions .
+
+        (##) ADC_FLAG_STRT: Regular channel start ==> to indicate when regular 
+             CHANNEL conversion starts.
+    [..]
+      (+) Interrupts :
+        (##) ADC_IT_OVR : specifies the interrupt source for Overrun detection 
+             event.  
+        (##) ADC_IT_EOC : specifies the interrupt source for Regular channel end
+             of conversion event.
+  
+  
+  *** Flags and Interrupts for ADC Injected channels ***
+  ======================================================
+    [..]
+      (+) Flags :
+        (##) ADC_FLAG_JEOC : Injected channel end of conversion ==> to indicate 
+             at the end of injected GROUP conversion  
+              
+        (##) ADC_FLAG_JSTRT: Injected channel start ==> to indicate hardware when 
+             injected GROUP conversion starts.
+    [..]
+      (+) Interrupts :
+        (##) ADC_IT_JEOC : specifies the interrupt source for Injected channel 
+             end of conversion event.     
+
+  *** General Flags and Interrupts for the ADC ***
+  ================================================ 
+    [..]
+      (+)Flags :
+        (##) ADC_FLAG_AWD: Analog watchdog ==> to indicate if the converted voltage 
+             crosses the programmed thresholds values.
+    [..]          
+      (+) Interrupts :
+        (##) ADC_IT_AWD : specifies the interrupt source for Analog watchdog event. 
+
+  
+    [..] The user should identify which mode will be used in his application to 
+         manage the ADC controller events: Polling mode or Interrupt mode.
+  
+    [..] In the Polling Mode it is advised to use the following functions:
+      (+) ADC_GetFlagStatus() : to check if flags events occur. 
+      (+) ADC_ClearFlag()     : to clear the flags events.
+      
+    [..] In the Interrupt Mode it is advised to use the following functions:
+      (+) ADC_ITConfig()          : to enable or disable the interrupt source.
+      (+) ADC_GetITStatus()       : to check if Interrupt occurs.
+      (+) ADC_ClearITPendingBit() : to clear the Interrupt pending Bit 
+                                   (corresponding Flag).

+                               when messages are pending in the receive FIFO.
+                               The corresponding interrupt pending bits are cleared 
+                               only by hardware.
+

+                               the filter while the FIFO was full.
+
+      (+) Operating Mode Interrupts
+         
+        (++) CAN_IT_WKU     :  Wake-up Interrupt
+                               if enabled, this interrupt source is pending when 
+                               a SOF bit has been detected while the CAN hardware 
+                               was in Sleep mode.

+
+      (+) Error Interrupts 
+

+                               if enabled, this interrupt source is pending when
+                               the warning limit has been reached (Receive Error 
+                               Counter or Transmit Error Counter=96).

+                               the Error Passive limit has been reached (Receive 
+                               Error Counter or Transmit Error Counter>127).
+                          
+        (++) CAN_IT_BOF     :  Bus-off Interrupt
+                               if enabled, this interrupt source is pending when
+                               CAN enters the bus-off state. The bus-off state is 
+                               entered on TEC overflow, greater than 255.
+                               This Flag is cleared only by hardware.
+                                  
+        (++) CAN_IT_LEC     :  Last error code Interrupt        
+                               if enabled, this interrupt source is pending  when
+                               a message has been transferred (reception or
+                               transmission) with error, and the error code is hold.
+                          
+        (++) CAN_IT_ERR     :  Error Interrupt
+                               if enabled, this interrupt source is pending when 
+                               an error condition is pending.      
+                      
+    [..] Managing the CAN controller events :
+ 
+         The user should identify which mode will be used in his application to 
+         manage the CAN controller events: Polling mode or Interrupt mode.
+  
+      (#) In the Polling Mode it is advised to use the following functions:
+        (++) CAN_GetFlagStatus() : to check if flags events occur. 
+        (++) CAN_ClearFlag()     : to clear the flags events.
+  
+
+  
+      (#) In the Interrupt Mode it is advised to use the following functions:
+        (++) CAN_ITConfig()       : to enable or disable the interrupt source.
+        (++) CAN_GetITStatus()    : to check if Interrupt occurs.
+        (++) CAN_ClearITPendingBit() : to clear the Interrupt pending Bit 
+            (corresponding Flag).
+        -@@-  This function has no impact on CAN_IT_FMP0 and CAN_IT_FMP1 Interrupts 
+             pending bits since there are cleared only by hardware.

+ ===================================================================      
+                 ##### How to use this driver #####
+ =================================================================== 
+ [..]
+   (#) Enable the CRYP controller clock using 
+       RCC_AHB2PeriphClockCmd(RCC_AHB2Periph_CRYP, ENABLE); function.
+  
+   (#) Initialise the CRYP using CRYP_Init(), CRYP_KeyInit() and if needed 
+       CRYP_IVInit(). 
+  
+   (#) Flush the IN and OUT FIFOs by using CRYP_FIFOFlush() function.
+  
+   (#) Enable the CRYP controller using the CRYP_Cmd() function. 
+  
+   (#) If using DMA for Data input and output transfer, activate the needed DMA 
+       Requests using CRYP_DMACmd() function 
+  
+   (#) If DMA is not used for data transfer, use CRYP_DataIn() and  CRYP_DataOut() 
+       functions to enter data to IN FIFO and get result from OUT FIFO.
+  
+   (#) To control CRYP events you can use one of the following two methods:
+       (++) Check on CRYP flags using the CRYP_GetFlagStatus() function.  
+       (++) Use CRYP interrupts through the function CRYP_ITConfig() at 
+            initialization phase and CRYP_GetITStatus() function into interrupt 
+            routines in processing phase.
+         
+   (#) Save and restore Cryptographic processor context using CRYP_SaveContext() 
+       and CRYP_RestoreContext() functions.     
+  
+  
+ *** Procedure to perform an encryption or a decryption ***
+ ========================================================== 
+  
+ *** Initialization ***
+ ====================== 
+ [..] 
+   (#) Initialize the peripheral using CRYP_Init(), CRYP_KeyInit() and CRYP_IVInit 
+       functions:
+       (++) Configure the key size (128-, 192- or 256-bit, in the AES only) 
+       (++) Enter the symmetric key 
+       (++) Configure the data type
+       (++) In case of decryption in AES-ECB or AES-CBC, you must prepare 
+            the key: configure the key preparation mode. Then Enable the CRYP 
+            peripheral using CRYP_Cmd() function: the BUSY flag is set. 
+            Wait until BUSY flag is reset : the key is prepared for decryption
+       (++) Configure the algorithm and chaining (the DES/TDES in ECB/CBC, the 
+            AES in ECB/CBC/CTR) 
+       (++) Configure the direction (encryption/decryption).
+       (++) Write the initialization vectors (in CBC or CTR modes only)
+  
+   (#) Flush the IN and OUT FIFOs using the CRYP_FIFOFlush() function
+  
+  
+  *** Basic Processing mode (polling mode) *** 
+  ============================================  
+  [..]
+    (#) Enable the cryptographic processor using CRYP_Cmd() function.
+  
+    (#) Write the first blocks in the input FIFO (2 to 8 words) using 
+        CRYP_DataIn() function.
+  
+    (#) Repeat the following sequence until the complete message has been 
+        processed:
+  
+        (++) Wait for flag CRYP_FLAG_OFNE occurs (using CRYP_GetFlagStatus() 
+            function), then read the OUT-FIFO using CRYP_DataOut() function
+            (1 block or until the FIFO is empty)
+  
+         (++) Wait for flag CRYP_FLAG_IFNF occurs, (using CRYP_GetFlagStatus() 
+            function then write the IN FIFO using CRYP_DataIn() function 
+            (1 block or until the FIFO is full)
+  
+    (#) At the end of the processing, CRYP_FLAG_BUSY flag will be reset and 
+          both FIFOs are empty (CRYP_FLAG_IFEM is set and CRYP_FLAG_OFNE is 
+          reset). You can disable the peripheral using CRYP_Cmd() function.
+  
+ *** Interrupts Processing mode *** 
+ ==================================
+ [..] In this mode, Processing is done when the data are transferred by the 
+      CPU during interrupts.
+  
+    (#) Enable the interrupts CRYP_IT_INI and CRYP_IT_OUTI using CRYP_ITConfig()
+        function.
+  
+    (#) Enable the cryptographic processor using CRYP_Cmd() function.
+  
+    (#) In the CRYP_IT_INI interrupt handler : load the input message into the 
+         IN FIFO using CRYP_DataIn() function . You can load 2 or 4 words at a 
+         time, or load data until the IN FIFO is full. When the last word of
+         the message has been entered into the IN FIFO, disable the CRYP_IT_INI 
+         interrupt (using CRYP_ITConfig() function).
+  
+    (#) In the CRYP_IT_OUTI interrupt handler : read the output message from 
+         the OUT FIFO using CRYP_DataOut() function. You can read 1 block (2 or 
+         4 words) at a time or read data until the FIFO is empty.
+         When the last word has been read, INIM=0, BUSY=0 and both FIFOs are 
+         empty (CRYP_FLAG_IFEM is set and CRYP_FLAG_OFNE is reset). 
+         You can disable the CRYP_IT_OUTI interrupt (using CRYP_ITConfig() 
+         function) and you can disable the peripheral using CRYP_Cmd() function.
+  
+ *** DMA Processing mode *** 
+ ===========================
+ [..] In this mode, Processing is done when the DMA is used to transfer the 
+      data from/to the memory.
+  
+    (#) Configure the DMA controller to transfer the input data from the 
+         memory using DMA_Init() function. 
+         The transfer length is the length of the message. 
+         As message padding is not managed by the peripheral, the message 
+         length must be an entire number of blocks. The data are transferred 
+         in burst mode. The burst length is 4 words in the AES and 2 or 4 
+         words in the DES/TDES. The DMA should be configured to set an 
+         interrupt on transfer completion of the output data to indicate that 
+         the processing is finished. 
+         Refer to DMA peripheral driver for more details.  
+  
+     (#) Enable the cryptographic processor using CRYP_Cmd() function. 
+         Enable the DMA requests CRYP_DMAReq_DataIN and CRYP_DMAReq_DataOUT 
+         using CRYP_DMACmd() function.
+  
+     (#) All the transfers and processing are managed by the DMA and the 
+         cryptographic processor. The DMA transfer complete interrupt indicates 
+         that the processing is complete. Both FIFOs are normally empty and 
+         CRYP_FLAG_BUSY flag is reset.

+ [..] This section provides functions allowing to configure the CRYP Interrupts and 
+      to get the status and Interrupts pending bits.
+
+ [..] The CRYP provides 2 Interrupts sources and 7 Flags:
+
+ *** Flags : ***
+ ===============
+ [..] 
+   (#) CRYP_FLAG_IFEM :  Set when Input FIFO is empty. This Flag is cleared only
+       by hardware.
+      
+   (#) CRYP_FLAG_IFNF :  Set when Input FIFO is not full. This Flag is cleared 
+       only by hardware.
+
+
+   (#) CRYP_FLAG_INRIS  : Set when Input FIFO Raw interrupt is pending it gives 
+       the raw interrupt state prior to masking of the input FIFO service interrupt.
+       This Flag is cleared only by hardware.
+     
+   (#) CRYP_FLAG_OFNE   : Set when Output FIFO not empty. This Flag is cleared 
+       only by hardware.
+        
+   (#) CRYP_FLAG_OFFU   : Set when Output FIFO is full. This Flag is cleared only 
+       by hardware.
+                           
+   (#) CRYP_FLAG_OUTRIS : Set when Output FIFO Raw interrupt is pending it gives 
+       the raw interrupt state prior to masking of the output FIFO service interrupt.
+       This Flag is cleared only by hardware.
+                               
+   (#) CRYP_FLAG_BUSY   : Set when the CRYP core is currently processing a block 
+       of data or a key preparation (for AES decryption). This Flag is cleared 
+       only by hardware. To clear it, the CRYP core must be disabled and the last
+       processing has completed. 
+
+ *** Interrupts : ***
+ ====================
+ [..]
+   (#) CRYP_IT_INI   : The input FIFO service interrupt is asserted when there 
+      are less than 4 words in the input FIFO. This interrupt is associated to 
+      CRYP_FLAG_INRIS flag.
+
+      -@- This interrupt is cleared by performing write operations to the input FIFO 
+          until it holds 4 or more words. The input FIFO service interrupt INMIS is 
+          enabled with the CRYP enable bit. Consequently, when CRYP is disabled, the 
+          INMIS signal is low even if the input FIFO is empty.
+
+
+
+   (#) CRYP_IT_OUTI  : The output FIFO service interrupt is asserted when there 
+       is one or more (32-bit word) data items in the output FIFO. This interrupt 
+       is associated to CRYP_FLAG_OUTRIS flag.
+
+       -@- This interrupt is cleared by reading data from the output FIFO until there 
+           is no valid (32-bit) word left (that is, the interrupt follows the state 
+           of the OFNE (output FIFO not empty) flag).
+
+ *** Managing the CRYP controller events : ***
+ =============================================
+ [..] The user should identify which mode will be used in his application to manage 
+      the CRYP controller events: Polling mode or Interrupt mode.
+
+   (#) In the Polling Mode it is advised to use the following functions:
+       (++) CRYP_GetFlagStatus() : to check if flags events occur. 
+
+       -@@- The CRYPT flags do not need to be cleared since they are cleared as 
+            soon as the associated event are reset.

+ ===============================================================================
+                      ##### DAC Peripheral features #####
+ ===============================================================================
+    [..]        
+      *** DAC Channels ***
+      ====================  
+    [..]  
+    The device integrates two 12-bit Digital Analog Converters that can 
+    be used independently or simultaneously (dual mode):
+      (#) DAC channel1 with DAC_OUT1 (PA4) as output
+      (#) DAC channel2 with DAC_OUT2 (PA5) as output
+  
+      *** DAC Triggers ***
+      ====================
+    [..]
+    Digital to Analog conversion can be non-triggered using DAC_Trigger_None
+    and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register 
+    using DAC_SetChannel1Data() / DAC_SetChannel2Data() functions.
+    [..] 
+    Digital to Analog conversion can be triggered by:
+      (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
+          The used pin (GPIOx_Pin9) must be configured in input mode.
+  
+      (#) Timers TRGO: TIM2, TIM4, TIM5, TIM6, TIM7 and TIM8 
+          (DAC_Trigger_T2_TRGO, DAC_Trigger_T4_TRGO...)
+          The timer TRGO event should be selected using TIM_SelectOutputTrigger()
+  
+      (#) Software using DAC_Trigger_Software
+  
+      *** DAC Buffer mode feature ***
+      =============================== 
+      [..] 
+      Each DAC channel integrates an output buffer that can be used to 
+      reduce the output impedance, and to drive external loads directly
+      without having to add an external operational amplifier.
+      To enable, the output buffer use  
+      DAC_InitStructure.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
+      [..]           
+      (@) Refer to the device datasheet for more details about output 
+          impedance value with and without output buffer.
+            
+       *** DAC wave generation feature ***
+       =================================== 
+       [..]     
+       Both DAC channels can be used to generate
+         (#) Noise wave using DAC_WaveGeneration_Noise
+         (#) Triangle wave using DAC_WaveGeneration_Triangle
+          
+          -@-  Wave generation can be disabled using DAC_WaveGeneration_None
+  
+       *** DAC data format ***
+       =======================
+       [..]   
+       The DAC data format can be:
+         (#) 8-bit right alignment using DAC_Align_8b_R
+         (#) 12-bit left alignment using DAC_Align_12b_L
+         (#) 12-bit right alignment using DAC_Align_12b_R
+  
+       *** DAC data value to voltage correspondence ***  
+       ================================================ 
+       [..] 
+       The analog output voltage on each DAC channel pin is determined
+       by the following equation: 
+       DAC_OUTx = VREF+ * DOR / 4095
+       with  DOR is the Data Output Register
+          VEF+ is the input voltage reference (refer to the device datasheet)
+        e.g. To set DAC_OUT1 to 0.7V, use
+          DAC_SetChannel1Data(DAC_Align_12b_R, 868);
+          Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
+  
+       *** DMA requests  ***
+       =====================
+       [..]    
+       A DMA1 request can be generated when an external trigger (but not
+       a software trigger) occurs if DMA1 requests are enabled using
+       DAC_DMACmd()
+       [..]
+       DMA1 requests are mapped as following:
+         (#) DAC channel1 : mapped on DMA1 Stream5 channel7 which must be 
+             already configured
+         (#) DAC channel2 : mapped on DMA1 Stream6 channel7 which must be 
+             already configured
+  
+      
+                      ##### How to use this driver #####
+ ===============================================================================
+    [..]          
+      (+) DAC APB clock must be enabled to get write access to DAC
+          registers using
+          RCC_APB1PeriphClockCmd(RCC_APB1Periph_DAC, ENABLE)
+      (+) Configure DAC_OUTx (DAC_OUT1: PA4, DAC_OUT2: PA5) in analog mode.
+      (+) Configure the DAC channel using DAC_Init() function
+      (+) Enable the DAC channel using DAC_Cmd() function

+                        ##### How to use this driver #####
+ ===============================================================================  
+    [..]       
+      The sequence below describes how to use this driver to capture image
+      from a camera module connected to the DCMI Interface.
+      This sequence does not take into account the configuration of the  
+      camera module, which should be made before to configure and enable
+      the DCMI to capture images.
+             
+      (#) Enable the clock for the DCMI and associated GPIOs using the following 
+          functions:
+          RCC_AHB2PeriphClockCmd(RCC_AHB2Periph_DCMI, ENABLE);
+          RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOx, ENABLE);
+  
+      (#) DCMI pins configuration 
+        (++) Connect the involved DCMI pins to AF13 using the following function 
+            GPIO_PinAFConfig(GPIOx, GPIO_PinSourcex, GPIO_AF_DCMI); 
+        (++) Configure these DCMI pins in alternate function mode by calling 
+            the function GPIO_Init();
+      
+      (#) Declare a DCMI_InitTypeDef structure, for example:
+          DCMI_InitTypeDef  DCMI_InitStructure;
+          and fill the DCMI_InitStructure variable with the allowed values
+          of the structure member.
+    
+      (#) Initialize the DCMI interface by calling the function
+          DCMI_Init(&DCMI_InitStructure); 
+    
+      (#) Configure the DMA2_Stream1 channel1 to transfer Data from DCMI DR
+          register to the destination memory buffer.
+    
+      (#) Enable DCMI interface using the function
+          DCMI_Cmd(ENABLE);
+                   
+      (#) Start the image capture using the function
+          DCMI_CaptureCmd(ENABLE);
+                   
+      (#) At this stage the DCMI interface waits for the first start of frame,
+          then a DMA request is generated continuously/once (depending on the
+          mode used, Continuous/Snapshot) to transfer the received data into
+          the destination memory. 
+     
+      -@-  If you need to capture only a rectangular window from the received
+           image, you have to use the DCMI_CROPConfig() function to configure 
+           the coordinates and size of the window to be captured, then enable 
+           the Crop feature using DCMI_CROPCmd(ENABLE);  
+           In this case, the Crop configuration should be made before to enable
+           and start the DCMI interface.

+ ===============================================================================      
+                       ##### How to use this driver #####
+ ===============================================================================
+    [..] 
+      (#) Enable The DMA controller clock using RCC_AHB1PeriphResetCmd(RCC_AHB1Periph_DMA1, ENABLE)
+          function for DMA1 or using RCC_AHB1PeriphResetCmd(RCC_AHB1Periph_DMA2, ENABLE)
+          function for DMA2.
+  
+      (#) Enable and configure the peripheral to be connected to the DMA Stream
+          (except for internal SRAM / FLASH memories: no initialization is 
+          necessary). 
+          
+      (#) For a given Stream, program the required configuration through following parameters:   
+          Source and Destination addresses, Transfer Direction, Transfer size, Source and Destination 
+          data formats, Circular or Normal mode, Stream Priority level, Source and Destination 
+          Incrementation mode, FIFO mode and its Threshold (if needed), Burst 
+          mode for Source and/or Destination (if needed) using the DMA_Init() function.
+          To avoid filling unneccessary fields, you can call DMA_StructInit() function
+          to initialize a given structure with default values (reset values), the modify
+          only necessary fields 
+          (ie. Source and Destination addresses, Transfer size and Data Formats).
+  
+      (#) Enable the NVIC and the corresponding interrupt(s) using the function 
+          DMA_ITConfig() if you need to use DMA interrupts. 
+  
+      (#) Optionally, if the Circular mode is enabled, you can use the Double buffer mode by configuring 
+          the second Memory address and the first Memory to be used through the function 
+          DMA_DoubleBufferModeConfig(). Then enable the Double buffer mode through the function
+          DMA_DoubleBufferModeCmd(). These operations must be done before step 6.
+      
+      (#) Enable the DMA stream using the DMA_Cmd() function. 
+                  
+      (#) Activate the needed Stream Request using PPP_DMACmd() function for
+          any PPP peripheral except internal SRAM and FLASH (ie. SPI, USART ...)
+          The function allowing this operation is provided in each PPP peripheral
+          driver (ie. SPI_DMACmd for SPI peripheral).
+          Once the Stream is enabled, it is not possible to modify its configuration
+          unless the stream is stopped and disabled.
+          After enabling the Stream, it is advised to monitor the EN bit status using
+          the function DMA_GetCmdStatus(). In case of configuration errors or bus errors
+          this bit will remain reset and all transfers on this Stream will remain on hold.      
+  
+      (#) Optionally, you can configure the number of data to be transferred
+          when the Stream is disabled (ie. after each Transfer Complete event
+          or when a Transfer Error occurs) using the function DMA_SetCurrDataCounter().
+          And you can get the number of remaining data to be transferred using 
+          the function DMA_GetCurrDataCounter() at run time (when the DMA Stream is
+          enabled and running).  
+                     
+      (#) To control DMA events you can use one of the following two methods:
+        (##) Check on DMA Stream flags using the function DMA_GetFlagStatus().  
+        (##) Use DMA interrupts through the function DMA_ITConfig() at initialization
+             phase and DMA_GetITStatus() function into interrupt routines in
+             communication phase.
+    [..]     
+          After checking on a flag you should clear it using DMA_ClearFlag()
+          function. And after checking on an interrupt event you should 
+          clear it using DMA_ClearITPendingBit() function.    
+                
+      (#) Optionally, if Circular mode and Double Buffer mode are enabled, you can modify
+          the Memory Addresses using the function DMA_MemoryTargetConfig(). Make sure that
+          the Memory Address to be modified is not the one currently in use by DMA Stream.
+          This condition can be monitored using the function DMA_GetCurrentMemoryTarget().
+                
+      (#) Optionally, Pause-Resume operations may be performed:
+          The DMA_Cmd() function may be used to perform Pause-Resume operation. 
+          When a transfer is ongoing, calling this function to disable the 
+          Stream will cause the transfer to be paused. All configuration registers 
+          and the number of remaining data will be preserved. When calling again 
+          this function to re-enable the Stream, the transfer will be resumed from 
+          the point where it was paused.          
+                   
+      -@- Memory-to-Memory transfer is possible by setting the address of the memory into
+           the Peripheral registers. In this mode, Circular mode and Double Buffer mode
+           are not allowed.
+    
+      -@- The FIFO is used mainly to reduce bus usage and to allow data 
+           packing/unpacking: it is possible to set different Data Sizes for 
+           the Peripheral and the Memory (ie. you can set Half-Word data size 
+           for the peripheral to access its data register and set Word data size
+           for the Memory to gain in access time. Each two Half-words will be 
+           packed and written in a single access to a Word in the Memory).
+      
+      -@- When FIFO is disabled, it is not allowed to configure different 
+           Data Sizes for Source and Destination. In this case the Peripheral 
+           Data Size will be applied to both Source and Destination.

+    This subsection provides function allowing to configure and control the double 
+    buffer mode parameters.
+    
+    [..]
+    The Double Buffer mode can be used only when Circular mode is enabled.
+    The Double Buffer mode cannot be used when transferring data from Memory to Memory.
+    
+    [..]
+    The Double Buffer mode allows to set two different Memory addresses from/to which
+    the DMA controller will access alternatively (after completing transfer to/from 
+    target memory 0, it will start transfer to/from target memory 1).
+    This allows to reduce software overhead for double buffering and reduce the CPU
+    access time.
+    
+    [..]
+    Two functions must be called before calling the DMA_Init() function:
+      (+) void DMA_DoubleBufferModeConfig(DMA_Stream_TypeDef* DMAy_Streamx, 
+          uint32_t Memory1BaseAddr, uint32_t DMA_CurrentMemory);
+      (+) void DMA_DoubleBufferModeCmd(DMA_Stream_TypeDef* DMAy_Streamx, FunctionalState NewState);
+      
+    [..]
+    DMA_DoubleBufferModeConfig() is called to configure the Memory 1 base address 
+    and the first Memory target from/to which the transfer will start after 
+    enabling the DMA Stream. Then DMA_DoubleBufferModeCmd() must be called 
+    to enable the Double Buffer mode (or disable it when it should not be used).
+  
+    [..]
+    Two functions can be called dynamically when the transfer is ongoing (or when the DMA Stream is 
+    stopped) to modify on of the target Memories addresses or to check wich Memory target is currently
+    used:
+      (+) void DMA_MemoryTargetConfig(DMA_Stream_TypeDef* DMAy_Streamx, 
+                uint32_t MemoryBaseAddr, uint32_t DMA_MemoryTarget);
+      (+) uint32_t DMA_GetCurrentMemoryTarget(DMA_Stream_TypeDef* DMAy_Streamx);
+      
+    [..]
+    DMA_MemoryTargetConfig() can be called to modify the base address of one of 
+    the two target Memories.
+    The Memory of which the base address will be modified must not be currently 
+    be used by the DMA Stream (ie. if the DMA Stream is currently transferring 
+    from Memory 1 then you can only modify base address of target Memory 0 and vice versa).
+    To check this condition, it is recommended to use the function DMA_GetCurrentMemoryTarget() which
+    returns the index of the Memory target currently in use by the DMA Stream.

+ ===================================================================
+
+ [..] External interrupt/event lines are mapped as following:
+   (#) All available GPIO pins are connected to the 16 external 
+       interrupt/event lines from EXTI0 to EXTI15.
+   (#) EXTI line 16 is connected to the PVD Output
+   (#) EXTI line 17 is connected to the RTC Alarm event
+   (#) EXTI line 18 is connected to the USB OTG FS Wakeup from suspend event                                    
+   (#) EXTI line 19 is connected to the Ethernet Wakeup event
+   (#) EXTI line 20 is connected to the USB OTG HS (configured in FS) Wakeup event 
+   (#) EXTI line 21 is connected to the RTC Tamper and Time Stamp events                                               
+   (#) EXTI line 22 is connected to the RTC Wakeup event
+          
+          
+                ##### How to use this driver #####
+ ===================================================================  
+ 
+ [..] In order to use an I/O pin as an external interrupt source, follow steps 
+      below:
+   (#) Configure the I/O in input mode using GPIO_Init()
+   (#) Select the input source pin for the EXTI line using SYSCFG_EXTILineConfig()
+   (#) Select the mode(interrupt, event) and configure the trigger 
+       selection (Rising, falling or both) using EXTI_Init()
+   (#) Configure NVIC IRQ channel mapped to the EXTI line using NVIC_Init()
+
+ [..]     
+   (@) SYSCFG APB clock must be enabled to get write access to SYSCFG_EXTICRx
+       registers using RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);

+   (#) Enable the GPIO AHB clock using the following function
+       RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOx, ENABLE);
+               
+   (#) Configure the GPIO pin(s) using GPIO_Init()
+       Four possible configuration are available for each pin:
+       (++) Input: Floating, Pull-up, Pull-down.
+       (++) Output: Push-Pull (Pull-up, Pull-down or no Pull)
+            Open Drain (Pull-up, Pull-down or no Pull). In output mode, the speed 
+            is configurable: 2 MHz, 25 MHz, 50 MHz or 100 MHz.
+       (++) Alternate Function: Push-Pull (Pull-up, Pull-down or no Pull) Open 
+            Drain (Pull-up, Pull-down or no Pull).
+       (++) Analog: required mode when a pin is to be used as ADC channel or DAC 
+            output.
+   
+   (#) Peripherals alternate function:
+       (++) For ADC and DAC, configure the desired pin in analog mode using 
+            GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AN;
+            (+++) For other peripherals (TIM, USART...):
+            (+++) Connect the pin to the desired peripherals' Alternate 
+                     Function (AF) using GPIO_PinAFConfig() function
+            (+++) Configure the desired pin in alternate function mode using
+                     GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AF
+            (+++) Select the type, pull-up/pull-down and output speed via 
+                     GPIO_PuPd, GPIO_OType and GPIO_Speed members
+            (+++) Call GPIO_Init() function
+          
+   (#) To get the level of a pin configured in input mode use GPIO_ReadInputDataBit()
+            
+   (#) To set/reset the level of a pin configured in output mode use 
+       GPIO_SetBits()/GPIO_ResetBits()
+                 
+   (#) During and just after reset, the alternate functions are not 
+       active and the GPIO pins are configured in input floating mode (except JTAG
+       pins).
+  
+   (#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose 
+       (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has 
+       priority over the GPIO function.
+  
+   (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as 
+       general purpose PH0 and PH1, respectively, when the HSE oscillator is off. 
+       The HSE has priority over the GPIO function.

+ *** HASH operation : *** 
+ ========================                 
+ [..]
+   (#) Enable the HASH controller clock using 
+       RCC_AHB2PeriphClockCmd(RCC_AHB2Periph_HASH, ENABLE) function.
+             
+   (#) Initialise the HASH using HASH_Init() function. 
+                 
+   (#) Reset the HASH processor core, so that the HASH will be ready 
+       to compute he message digest of a new message by using HASH_Reset() function.
+  
+   (#) Enable the HASH controller using the HASH_Cmd() function. 
+                  
+   (#) if using DMA for Data input transfer, Activate the DMA Request 
+       using HASH_DMACmd() function 
+                      
+   (#) if DMA is not used for data transfer, use HASH_DataIn() function 
+       to enter data to IN FIFO.
+               
+            
+   (#) Configure the Number of valid bits in last word of the message 
+       using HASH_SetLastWordValidBitsNbr() function.
+               
+   (#) if the message length is not an exact multiple of 512 bits, 
+       then the function HASH_StartDigest() must be called to launch the computation
+       of the final digest.     
+               
+   (#) Once computed, the digest can be read using HASH_GetDigest() function.         
+                     
+   (#) To control HASH events you can use one of the following wo methods:
+       (++) Check on HASH flags using the HASH_GetFlagStatus() function.  
+       (++) Use HASH interrupts through the function HASH_ITConfig() at 
+            initialization phase and HASH_GetITStatus() function into 
+            interrupt routines in hashing phase.
+            After checking on a flag you should clear it using HASH_ClearFlag()
+            function. And after checking on an interrupt event you should 
+            clear it using HASH_ClearITPendingBit() function.     
+                       
+   (#) Save and restore hash processor context using 
+       HASH_SaveContext() and HASH_RestoreContext() functions.     
+                
+  
+              
+ *** HMAC operation : *** 
+ ========================
+ [..] The HMAC algorithm is used for message authentication, by 
+      irreversibly binding the message being processed to a key chosen 
+      by the user. 
+      For HMAC specifications, refer to "HMAC: keyed-hashing for message 
+      authentication, H. Krawczyk, M. Bellare, R. Canetti, February 1997"
+            
+ [..] Basically, the HMAC algorithm consists of two nested hash operations:
+      HMAC(message) = Hash[((key | pad) XOR 0x5C) | Hash(((key | pad) XOR 0x36) | message)]
+      where:
+      (+) "pad" is a sequence of zeroes needed to extend the key to the 
+          length of the underlying hash function data block (that is 
+          512 bits for both the SHA-1 and MD5 hash algorithms)
+      (+) "|"   represents the concatenation operator 
+            
+           
+ [..]To compute the HMAC, four different phases are required:                  
+   (#) Initialise the HASH using HASH_Init() function to do HMAC 
+       operation. 
+                  
+   (#) The key (to be used for the inner hash function) is then given to the core. 
+       This operation follows the same mechanism as the one used to send the 
+       message in the hash operation (that is, by HASH_DataIn() function and, 
+       finally, HASH_StartDigest() function.
+            
+   (#) Once the last word has been entered and computation has started, 
+       the hash processor elaborates the key. It is then ready to accept the message
+       text using the same mechanism as the one used to send the message in the
+       hash operation.
+         
+   (#) After the first hash round, the hash processor returns "ready" to indicate 
+       that it is ready to receive the key to be used for the outer hash function 
+       (normally, this key is the same as the one used for the inner hash function). 
+       When the last word of the key is entered and computation starts, the HMAC 
+       result is made available using HASH_GetDigest() function.
+

+ =============== 
+ [..]
+   (#) HASH_FLAG_DINIS : set when 16 locations are free in the Data IN FIFO 
+      which means that a  new block (512 bit) can be entered into the input buffer.

+       This Flag is cleared only by hardware.

+       the Data IN FIFO contains at least one word of data. This Flag is cleared 
+       only by hardware.
+     
+ *** Interrupts : ***
+ ====================
+ [..]   
+   (#) HASH_IT_DINI  : if enabled, this interrupt source is pending when 16 
+       locations are free in the Data IN FIFO  which means that a new block (512 bit)
+       can be entered into the input buffer. This interrupt source is cleared using

+       calculation is complete. This interrupt source is cleared using

+@verbatim   
+ ===============================================================================
+          ##### Interrupts, events and flags management functions #####
+ ===============================================================================
+    [..]
+    This section provides functions allowing to configure the I2C Interrupts 
+    sources and check or clear the flags or pending bits status.
+    The user should identify which mode will be used in his application to manage 
+    the communication: Polling mode, Interrupt mode or DMA mode. 
+
+
+                ##### I2C State Monitoring Functions #####                   
+ =============================================================================== 
+    [..]  
+    This I2C driver provides three different ways for I2C state monitoring
+    depending on the application requirements and constraints:
+         
+   
+     (#) Basic state monitoring (Using I2C_CheckEvent() function)
+     
+        It compares the status registers (SR1 and SR2) content to a given event
+        (can be the combination of one or more flags).
+        It returns SUCCESS if the current status includes the given flags 
+        and returns ERROR if one or more flags are missing in the current status.
+
+          (++) When to use
+             (+++) This function is suitable for most applications as well as for startup 
+               activity since the events are fully described in the product reference 
+               manual (RM0090).
+             (+++) It is also suitable for users who need to define their own events.
+
+          (++) Limitations
+               If an error occurs (ie. error flags are set besides to the monitored 
+               flags), the I2C_CheckEvent() function may return SUCCESS despite 
+               the communication hold or corrupted real state. 
+               In this case, it is advised to use error interrupts to monitor 
+               the error events and handle them in the interrupt IRQ handler.
+         
+     -@@- For error management, it is advised to use the following functions:
+        (+@@) I2C_ITConfig() to configure and enable the error interrupts (I2C_IT_ERR).
+        (+@@) I2Cx_ER_IRQHandler() which is called when the error interrupt occurs.
+              Where x is the peripheral instance (I2C1, I2C2 ...)
+        (+@@) I2C_GetFlagStatus() or I2C_GetITStatus()  to be called into the 
+              I2Cx_ER_IRQHandler() function in order to determine which error occurred.
+        (+@@) I2C_ClearFlag() or I2C_ClearITPendingBit() and/or I2C_SoftwareResetCmd() 
+              and/or I2C_GenerateStop() in order to clear the error flag and source 
+              and return to correct  communication status.
+             
+ 
+     (#) Advanced state monitoring (Using the function I2C_GetLastEvent())
+
+        Using the function I2C_GetLastEvent() which returns the image of both status 
+        registers in a single word (uint32_t) (Status Register 2 value is shifted left 
+        by 16 bits and concatenated to Status Register 1).
+
+          (++) When to use
+             (+++) This function is suitable for the same applications above but it 
+               allows to overcome the mentioned limitation of I2C_GetFlagStatus() 
+               function.
+             (+++) The returned value could be compared to events already defined in 
+               the library (stm32f4xx_i2c.h) or to custom values defined by user.
+               This function is suitable when multiple flags are monitored at the 
+               same time.
+             (+++) At the opposite of I2C_CheckEvent() function, this function allows 
+               user to choose when an event is accepted (when all events flags are 
+               set and no other flags are set or just when the needed flags are set 
+               like I2C_CheckEvent() function.
+
+          (++) Limitations
+             (+++) User may need to define his own events.
+             (+++) Same remark concerning the error management is applicable for this 
+               function if user decides to check only regular communication flags 
+               (and ignores error flags).
+      
+ 
+     (#) Flag-based state monitoring (Using the function I2C_GetFlagStatus())
+     
+      Using the function I2C_GetFlagStatus() which simply returns the status of 
+      one single flag (ie. I2C_FLAG_RXNE ...). 
+
+          (++) When to use
+             (+++) This function could be used for specific applications or in debug 
+               phase.
+             (+++) It is suitable when only one flag checking is needed (most I2C 
+               events are monitored through multiple flags).
+          (++) Limitations: 
+             (+++) When calling this function, the Status register is accessed. 
+               Some flags are cleared when the status register is accessed. 
+               So checking the status of one Flag, may clear other ones.
+             (+++) Function may need to be called twice or more in order to monitor 
+               one single event.
+ 
+   For detailed description of Events, please refer to section I2C_Events in 
+   stm32f4xx_i2c.h file.

+  * @brief   This file provides firmware functions to manage the following 
+  *          functionalities of the Independent watchdog (IWDG) peripheral:

+  *           + IWDG activation
+  *           + Flag management

+    @verbatim    
+ ===============================================================================
+                          ##### IWDG features #####
+ ===============================================================================
+    [..]  
+      The IWDG can be started by either software or hardware (configurable
+      through option byte).
+              
+      The IWDG is clocked by its own dedicated low-speed clock (LSI) and
+      thus stays active even if the main clock fails.
+      Once the IWDG is started, the LSI is forced ON and cannot be disabled
+      (LSI cannot be disabled too), and the counter starts counting down from 
+      the reset value of 0xFFF. When it reaches the end of count value (0x000)
+      a system reset is generated.
+      The IWDG counter should be reloaded at regular intervals to prevent
+      an MCU reset.
+                             
+      The IWDG is implemented in the VDD voltage domain that is still functional
+      in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).          
+              
+      IWDGRST flag in RCC_CSR register can be used to inform when a IWDG
+      reset occurs.
+              
+      Min-max timeout value @32KHz (LSI): ~125us / ~32.7s
+      The IWDG timeout may vary due to LSI frequency dispersion. STM32F4xx
+      devices provide the capability to measure the LSI frequency (LSI clock
+      connected internally to TIM5 CH4 input capture). The measured value
+      can be used to have an IWDG timeout with an acceptable accuracy. 
+      For more information, please refer to the STM32F4xx Reference manual
+            
+                     ##### How to use this driver #####
+ ===============================================================================
+    [..]
+      (#) Enable write access to IWDG_PR and IWDG_RLR registers using
+          IWDG_WriteAccessCmd(IWDG_WriteAccess_Enable) function
+                 
+      (#) Configure the IWDG prescaler using IWDG_SetPrescaler() function
+              
+      (#) Configure the IWDG counter value using IWDG_SetReload() function.
+          This value will be loaded in the IWDG counter each time the counter
+          is reloaded, then the IWDG will start counting down from this value.
+              
+      (#) Start the IWDG using IWDG_Enable() function, when the IWDG is used
+          in software mode (no need to enable the LSI, it will be enabled
+          by hardware)
+               
+      (#) Then the application program must reload the IWDG counter at regular
+          intervals during normal operation to prevent an MCU reset, using
+          IWDG_ReloadCounter() function.

+      (+) The backup domain includes 4 Kbytes of backup SRAM accessible only from

+          is enabled. It can be considered as an internal EEPROM when VBAT is

+
+      (+) The backup SRAM is not mass erased by an tamper event. It is read 
+          protected to prevent confidential data, such as cryptographic private

+      (+) For STM32F405xx/407xx and STM32F415xx/417xx  Devices, the regulator can be     
+          configured on the fly through PWR_MainRegulatorModeConfig() function which

+        (++) When this bit is reset (Regulator voltage output Scale 2 mode selected) 
+             the System frequency can go up to 144 MHz.
+             
+       (+) For STM32F42xxx/43xxx Devices, the regulator can be configured through    
+           PWR_MainRegulatorModeConfig() function which configure VOS[1:0] bits in
+           PWR_CR register:  
+           which configure VOS[1:0] bits in PWR_CR register: 
+        (++) When VOS[1:0] = 11 (Regulator voltage output Scale 1 mode selected) 
+             the System frequency can go up to 168 MHz. 
+        (++) When VOS[1:0] = 10 (Regulator voltage output Scale 2 mode selected) 
+             the System frequency can go up to 144 MHz.

+                          
+       (+) For STM32F42xxx/43xxx Devices, the scale can be modified only when the PLL 
+           is OFF and the HSI or HSE clock source is selected as system clock. 
+           The new value programmed is active only when the PLL is ON.
+           When the PLL is OFF, the voltage scale 3 is automatically selected. 
+        Refer to the datasheets for more details.
+        
+       (+) For STM32F42xxx/43xxx Devices, in Run mode: the main regulator has
+           2 operating modes available:
+        (++) Normal mode: The CPU and core logic operate at maximum frequency at a given 
+             voltage scaling (scale 1, scale 2 or scale 3)
+        (++) Over-drive mode: This mode allows the CPU and the core logic to operate at a

+            the sequence described in Reference manual.
+             
+       (+) For STM32F42xxx/43xxx Devices, in Stop mode: the main regulator or low power regulator 
+           supplies a low power voltage to the 1.2V domain, thus preserving the content of registers 
+           and internal SRAM. 2 operating modes are available:
+         (++) Normal mode: the 1.2V domain is preserved in nominal leakage mode. This mode is only 
+              available when the main regulator or the low power regulator is used in Scale 3 or 
+              low voltage mode.

+      The devices feature 3 low-power modes:
+      (+) Sleep mode: Cortex-M4 core stopped, peripherals kept running.
+      (+) Stop mode: all clocks are stopped, regulator running, regulator 
+          in low power mode
+      (+) Standby mode: 1.2V domain powered off.
+   
+   *** Sleep mode ***
+   ==================
+    [..]
+      (+) Entry:
+        (++) The Sleep mode is entered by using the __WFI() or __WFE() functions.
+      (+) Exit:
+        (++) Any peripheral interrupt acknowledged by the nested vectored interrupt 
+             controller (NVIC) can wake up the device from Sleep mode.
+
+   *** Stop mode ***
+   =================
+    [..]
+      In Stop mode, all clocks in the 1.2V domain are stopped, the PLL, the HSI,
+      and the HSE RC oscillators are disabled. Internal SRAM and register contents 
+      are preserved.
+      The voltage regulator can be configured either in normal or low-power mode.
+      To minimize the consumption In Stop mode, FLASH can be powered off before 
+      entering the Stop mode. It can be switched on again by software after exiting 
+      the Stop mode using the PWR_FlashPowerDownCmd() function. 
+   
+      (+) Entry:

+      
+   *** Standby mode ***
+   ====================
+    [..]
+      The Standby mode allows to achieve the lowest power consumption. It is based 
+      on the Cortex-M4 deepsleep mode, with the voltage regulator disabled. 
+      The 1.2V domain is consequently powered off. The PLL, the HSI oscillator and 
+      the HSE oscillator are also switched off. SRAM and register contents are lost 
+      except for the RTC registers, RTC backup registers, backup SRAM and Standby 
+      circuitry.
+   
+      The voltage regulator is OFF.
+

+      Wakeup event, a tamper event, a time-stamp event, or a comparator event, 
+      without depending on an external interrupt (Auto-wakeup mode).
+
+      (#) RTC auto-wakeup (AWU) from the Stop mode
+       
+        (++) To wake up from the Stop mode with an RTC alarm event, it is necessary to:

+ ===================================================================================  
+    [..]
+      This section provide functions allowing to configure the internal/external clocks,
+      PLLs, CSS and MCO pins.
+  
+      (#) HSI (high-speed internal), 16 MHz factory-trimmed RC used directly or through
+          the PLL as System clock source.
+
+      (#) LSI (low-speed internal), 32 KHz low consumption RC used as IWDG and/or RTC
+          clock source.
+
+      (#) HSE (high-speed external), 4 to 26 MHz crystal oscillator used directly or
+          through the PLL as System clock source. Can be used also as RTC clock source.
+
+      (#) LSE (low-speed external), 32 KHz oscillator used as RTC clock source.   
+
+      (#) PLL (clocked by HSI or HSE), featuring two different output clocks:
+        (++) The first output is used to generate the high speed system clock (up to 168 MHz)
+        (++) The second output is used to generate the clock for the USB OTG FS (48 MHz),
+             the random analog generator (<=48 MHz) and the SDIO (<= 48 MHz).
+
+      (#) PLLI2S (clocked by HSI or HSE), used to generate an accurate clock to achieve 
+          high-quality audio performance on the I2S interface or SAI interface in case 
+          of STM32F429x/439x devices.
+     
+      (#) PLLSAI clocked by (HSI or HSE), used to generate an accurate clock to SAI 
+          interface and LCD TFT controller available only for STM32F42xxx/43xxx devices.
+  
+      (#) CSS (Clock security system), once enable and if a HSE clock failure occurs 
+         (HSE used directly or through PLL as System clock source), the System clock
+         is automatically switched to HSI and an interrupt is generated if enabled. 
+         The interrupt is linked to the Cortex-M4 NMI (Non-Maskable Interrupt) 
+         exception vector.   
+
+      (#) MCO1 (microcontroller clock output), used to output HSI, LSE, HSE or PLL
+          clock (through a configurable prescaler) on PA8 pin.
+
+      (#) MCO2 (microcontroller clock output), used to output HSE, PLL, SYSCLK or PLLI2S

+ ===============================================================================
+      ##### System, AHB and APB busses clocks configuration functions #####
+ ===============================================================================  
+    [..]
+      This section provide functions allowing to configure the System, AHB, APB1 and 
+      APB2 busses clocks.
+  
+      (#) Several clock sources can be used to drive the System clock (SYSCLK): HSI,
+          HSE and PLL.
+          The AHB clock (HCLK) is derived from System clock through configurable 
+          prescaler and used to clock the CPU, memory and peripherals mapped 
+          on AHB bus (DMA, GPIO...). APB1 (PCLK1) and APB2 (PCLK2) clocks are derived 
+          from AHB clock through configurable prescalers and used to clock 
+          the peripherals mapped on these busses. You can use 
+          "RCC_GetClocksFreq()" function to retrieve the frequencies of these clocks.  
+
+      -@- All the peripheral clocks are derived from the System clock (SYSCLK) except:
+        (+@) I2S: the I2S clock can be derived either from a specific PLL (PLLI2S) or
+             from an external clock mapped on the I2S_CKIN pin. 
+             You have to use RCC_I2SCLKConfig() function to configure this clock. 
+        (+@) RTC: the RTC clock can be derived either from the LSI, LSE or HSE clock
+             divided by 2 to 31. You have to use RCC_RTCCLKConfig() and RCC_RTCCLKCmd()
+             functions to configure this clock. 
+        (+@) USB OTG FS, SDIO and RTC: USB OTG FS require a frequency equal to 48 MHz
+             to work correctly, while the SDIO require a frequency equal or lower than
+             to 48. This clock is derived of the main PLL through PLLQ divider.
+        (+@) IWDG clock which is always the LSI clock.
+       
+      (#) For STM32F405xx/407xx and STM32F415xx/417xx devices, the maximum frequency 
+         of the SYSCLK and HCLK is 168 MHz, PCLK2 84 MHz and PCLK1 42 MHz. Depending

+
+ ===================================================================
+              ##### Backup Domain Operating Condition #####
+ ===================================================================
+ [..] The real-time clock (RTC), the RTC backup registers, and the backup 
+      SRAM (BKP SRAM) can be powered from the VBAT voltage when the main 
+      VDD supply is powered off.
+      To retain the content of the RTC backup registers, backup SRAM, and supply 
+      the RTC when VDD is turned off, VBAT pin can be connected to an optional 
+      standby voltage supplied by a battery or by another source.
+
+ [..] To allow the RTC to operate even when the main digital supply (VDD) is turned
+      off, the VBAT pin powers the following blocks:
+   (#) The RTC
+   (#) The LSE oscillator
+   (#) The backup SRAM when the low power backup regulator is enabled
+   (#) PC13 to PC15 I/Os, plus PI8 I/O (when available)
+  
+ [..] When the backup domain is supplied by VDD (analog switch connected to VDD),
+      the following functions are available:
+   (#) PC14 and PC15 can be used as either GPIO or LSE pins
+   (#) PC13 can be used as a GPIO or as the RTC_AF1 pin
+   (#) PI8 can be used as a GPIO or as the RTC_AF2 pin
+  
+ [..] When the backup domain is supplied by VBAT (analog switch connected to VBAT 
+      because VDD is not present), the following functions are available:
+   (#) PC14 and PC15 can be used as LSE pins only
+   (#) PC13 can be used as the RTC_AF1 pin 
+   (#) PI8 can be used as the RTC_AF2 pin
+  
+            
+                   ##### Backup Domain Reset #####
+ ===================================================================
+ [..] The backup domain reset sets all RTC registers and the RCC_BDCR register 
+      to their reset values. The BKPSRAM is not affected by this reset. The only
+      way of resetting the BKPSRAM is through the Flash interface by requesting 
+      a protection level change from 1 to 0.
+ [..] A backup domain reset is generated when one of the following events occurs:
+   (#) Software reset, triggered by setting the BDRST bit in the 
+       RCC Backup domain control register (RCC_BDCR). You can use the
+       RCC_BackupResetCmd().
+   (#) VDD or VBAT power on, if both supplies have previously been powered off.
+  
+
+                   ##### Backup Domain Access #####
+ ===================================================================
+ [..] After reset, the backup domain (RTC registers, RTC backup data 
+      registers and backup SRAM) is protected against possible unwanted write 
+      accesses. 
+ [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
+   (+) Enable the Power Controller (PWR) APB1 interface clock using the
+       RCC_APB1PeriphClockCmd() function.
+   (+) Enable access to RTC domain using the PWR_BackupAccessCmd() function.
+   (+) Select the RTC clock source using the RCC_RTCCLKConfig() function.
+   (+) Enable RTC Clock using the RCC_RTCCLKCmd() function.
+  
+  
+                  ##### How to use RTC Driver #####
+ ===================================================================
+ [..] 
+   (+) Enable the RTC domain access (see description in the section above)
+   (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour 
+       format using the RTC_Init() function.
+  
+ *** Time and Date configuration ***
+ ===================================
+ [..] 
+   (+) To configure the RTC Calendar (Time and Date) use the RTC_SetTime()
+       and RTC_SetDate() functions.
+   (+) To read the RTC Calendar, use the RTC_GetTime() and RTC_GetDate() functions.
+   (+) Use the RTC_DayLightSavingConfig() function to add or sub one
+       hour to the RTC Calendar.    
+  
+ *** Alarm configuration ***
+ ===========================
+ [..]
+   (+) To configure the RTC Alarm use the RTC_SetAlarm() function.
+   (+) Enable the selected RTC Alarm using the RTC_AlarmCmd() function
+   (+) To read the RTC Alarm, use the RTC_GetAlarm() function.
+   (+) To read the RTC alarm SubSecond, use the RTC_GetAlarmSubSecond() function.
+  
+ *** RTC Wakeup configuration ***
+ ================================
+ [..] 
+   (+) Configure the RTC Wakeup Clock source use the RTC_WakeUpClockConfig()
+       function.
+   (+) Configure the RTC WakeUp Counter using the RTC_SetWakeUpCounter() function  
+   (+) Enable the RTC WakeUp using the RTC_WakeUpCmd() function  
+   (+) To read the RTC WakeUp Counter register, use the RTC_GetWakeUpCounter() 
+       function.
+  
+ *** Outputs configuration ***
+ =============================
+ [..] The RTC has 2 different outputs:
+   (+) AFO_ALARM: this output is used to manage the RTC Alarm A, Alarm B
+       and WaKeUp signals. To output the selected RTC signal on RTC_AF1 pin, use the 
+       RTC_OutputConfig() function.                
+   (+) AFO_CALIB: this output is 512Hz signal or 1Hz. To output the RTC Clock on 
+       RTC_AF1 pin, use the RTC_CalibOutputCmd() function.
+  
+ *** Smooth digital Calibration configuration ***
+ ================================================    
+ [..]
+   (+) Configure the RTC Original Digital Calibration Value and the corresponding
+       calibration cycle period (32s,16s and 8s) using the RTC_SmoothCalibConfig() 
+       function.
+  
+ *** Coarse digital Calibration configuration ***
+ ================================================
+ [..]
+   (+) Configure the RTC Coarse Calibration Value and the corresponding
+       sign using the RTC_CoarseCalibConfig() function.
+   (+) Enable the RTC Coarse Calibration using the RTC_CoarseCalibCmd() function  
+  
+ *** TimeStamp configuration ***
+ ===============================
+ [..]
+   (+) Configure the RTC_AF1 trigger and enables the RTC TimeStamp using the RTC
+      _TimeStampCmd() function.
+   (+) To read the RTC TimeStamp Time and Date register, use the RTC_GetTimeStamp()
+       function.
+   (+) To read the RTC TimeStamp SubSecond register, use the 
+       RTC_GetTimeStampSubSecond() function.
+   (+) The TAMPER1 alternate function can be mapped either to RTC_AF1(PC13)
+       or RTC_AF2 (PI8) depending on the value of TAMP1INSEL bit in 
+       RTC_TAFCR register. You can use the  RTC_TamperPinSelection() function to
+       select the corresponding pin.     
+  
+ *** Tamper configuration ***
+ ============================
+ [..]
+   (+) Enable the RTC Tamper using the RTC_TamperCmd() function.
+   (+) Configure the Tamper filter count using RTC_TamperFilterConfig()
+       function. 
+   (+) Configure the RTC Tamper trigger Edge or Level according to the Tamper 
+       filter (if equal to 0 Edge else Level) value using the RTC_TamperConfig() 
+       function.
+   (+) Configure the Tamper sampling frequency using RTC_TamperSamplingFreqConfig()
+       function.
+   (+) Configure the Tamper precharge or discharge duration using 
+       RTC_TamperPinsPrechargeDuration() function.
+   (+) Enable the Tamper Pull-UP using RTC_TamperPullUpDisableCmd() function.
+   (+) Enable the Time stamp on Tamper detection event using  
+       TC_TSOnTamperDetecCmd() function.
+   (+) The TIMESTAMP alternate function can be mapped to either RTC_AF1 
+       or RTC_AF2 depending on the value of the TSINSEL bit in the RTC_TAFCR 
+       register. You can use the  RTC_TimeStampPinSelection() function to select 
+       the corresponding pin. 
+  
+ *** Backup Data Registers configuration ***
+ ===========================================
+ [..]
+   (+) To write to the RTC Backup Data registers, use the RTC_WriteBackupRegister()
+       function.  
+   (+) To read the RTC Backup Data registers, use the RTC_ReadBackupRegister()
+       function.
+   
+
+                  ##### RTC and low power modes #####
+ ===================================================================
+ [..] The MCU can be woken up from a low power mode by an RTC alternate 
+      function.
+ [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B), 
+      RTC wakeup, RTC tamper event detection and RTC time stamp event detection.
+      These RTC alternate functions can wake up the system from the Stop and 
+      Standby lowpower modes.
+ [..] The system can also wake up from low power modes without depending 
+      on an external interrupt (Auto-wakeup mode), by using the RTC alarm 
+      or the RTC wakeup events.
+ [..] The RTC provides a programmable time base for waking up from the 
+      Stop or Standby mode at regular intervals.
+      Wakeup from STOP and Standby modes is possible only when the RTC clock source
+      is LSE or LSI.
+  
+
+          ##### Selection of RTC_AF1 alternate functions #####
+ ===================================================================
+ [..] The RTC_AF1 pin (PC13) can be used for the following purposes:
+   (+) AFO_ALARM output
+   (+) AFO_CALIB output
+   (+) AFI_TAMPER
+   (+) AFI_TIMESTAMP

+ ===============================================================================
+ 
+ [..] This section provide functions allowing to initialize and configure the RTC
+      Prescaler (Synchronous and Asynchronous), RTC Hour format, disable RTC registers
+      Write protection, enter and exit the RTC initialization mode, RTC registers
+      synchronization check and reference clock detection enable.
+  
+   (#) The RTC Prescaler is programmed to generate the RTC 1Hz time base. It is
+       split into 2 programmable prescalers to minimize power consumption.
+       (++) A 7-bit asynchronous prescaler and A 13-bit synchronous prescaler.
+       (++) When both prescalers are used, it is recommended to configure the 
+            asynchronous prescaler to a high value to minimize consumption.
+
+   (#) All RTC registers are Write protected. Writing to the RTC registers
+       is enabled by writing a key into the Write Protection register, RTC_WPR.
+
+   (#) To Configure the RTC Calendar, user application should enter initialization
+       mode. In this mode, the calendar counter is stopped and its value can be 
+       updated. When the initialization sequence is complete, the calendar restarts 
+       counting after 4 RTCCLK cycles.
+
+   (#) To read the calendar through the shadow registers after Calendar initialization,
+       calendar update or after wakeup from low power modes the software must first 
+       clear the RSF flag. The software must then wait until it is set again before 
+       reading the calendar, which means that the calendar registers have been 
+       correctly copied into the RTC_TR and RTC_DR shadow registers.
+       The RTC_WaitForSynchro() function implements the above software sequence 
+       (RSF clear and RSF check).

+ ===============================================================================  
+  [..]
+  This section provides a set of functions allowing to configure the SAI Interrupts 
+  sources and check or clear the flags or pending bits status.
+  The user should identify which mode will be used in his application to manage 
+  the communication: Polling mode, Interrupt mode or DMA mode. 
+    
+  *** Polling Mode ***
+  ====================
+  [..]
+  In Polling Mode, the SAI communication can be managed by 7 flags:
+     (#) SAI_FLAG_FREQ : to indicate if there is a FIFO Request to write or to read.
+     (#) SAI_FLAG_MUTEDET : to indicate if a MUTE frame detected
+     (#) SAI_FLAG_OVRUDR : to indicate if an Overrun or Underrun error occur
+     (#) SAI_FLAG_AFSDET : to indicate if there is the detection of a audio frame 
+                          synchronisation (FS) earlier than expected
+     (#) SAI_FLAG_LFSDET : to indicate if there is the detection of a audio frame 
+                          synchronisation (FS) later than expected              
+     (#) SAI_FLAG_CNRDY : to indicate if  the codec is not ready to communicate during 
+                         the reception of the TAG 0 (slot0) of the AC97 audio frame 
+     (#) SAI_FLAG_WCKCFG: to indicate if wrong clock configuration in master mode 
+                         error occurs.
+  [..]
+  In this Mode it is advised to use the following functions:
+     (+) FlagStatus SAI_GetFlagStatus(SAI_Block_TypeDef* SAI_Block_x, uint32_t SAI_FLAG);
+     (+) void SAI_ClearFlag(SAI_Block_TypeDef* SAI_Block_x, uint32_t SAI_FLAG);
+
+  *** Interrupt Mode ***
+  ======================
+  [..]
+  In Interrupt Mode, the SAI communication can be managed by 7 interrupt sources
+  and 7 pending bits: 
+  (+) Pending Bits:
+     (##) SAI_IT_FREQ : to indicate if there is a FIFO Request to write or to read.
+     (##) SAI_IT_MUTEDET : to indicate if a MUTE frame detected.
+     (##) SAI_IT_OVRUDR : to indicate if an Overrun or Underrun error occur.
+     (##) SAI_IT_AFSDET : to indicate if there is the detection of a audio frame 
+                          synchronisation (FS) earlier than expected.
+     (##) SAI_IT_LFSDET : to indicate if there is the detection of a audio frame 
+                          synchronisation (FS) later than expected.              
+     (##) SAI_IT_CNRDY : to indicate if  the codec is not ready to communicate during 
+                         the reception of the TAG 0 (slot0) of the AC97 audio frame. 
+     (##) SAI_IT_WCKCFG: to indicate if wrong clock configuration in master mode 
+                         error occurs.
+
+  (+) Interrupt Source:
+     (##) SAI_IT_FREQ : specifies the interrupt source for FIFO Request.
+     (##) SAI_IT_MUTEDET : specifies the interrupt source for MUTE frame detected.
+     (##) SAI_IT_OVRUDR : specifies the interrupt source for overrun or underrun error.
+     (##) SAI_IT_AFSDET : specifies the interrupt source for anticipated frame synchronization
+                          detection interrupt.
+     (##) SAI_IT_LFSDET : specifies the interrupt source for late frame synchronization
+                          detection interrupt.             
+     (##) SAI_IT_CNRDY : specifies the interrupt source for codec not ready interrupt
+     (##) SAI_IT_WCKCFG: specifies the interrupt source for wrong clock configuration
+                         interrupt.
+  [..]                     
+  In this Mode it is advised to use the following functions:
+     (+) void SAI_ITConfig(SAI_Block_TypeDef* SAI_Block_x, uint32_t SAI_IT, FunctionalState NewState);
+     (+) ITStatus SAI_GetITStatus(SAI_Block_TypeDef* SAI_Block_x, uint32_t SAI_IT);
+     (+) void SAI_ClearITPendingBit(SAI_Block_TypeDef* SAI_Block_x, uint32_t SAI_IT);
+
+  *** DMA Mode ***
+  ================
+  [..]
+  In DMA Mode, each SAI audio block has an independent DMA interface in order to 
+  read or to write into the SAI_xDR register (to hit the internal FIFO). 
+  There is one DMA channel by audio block following basic DMA request/acknowledge 
+  protocol.
+  [..]
+  In this Mode it is advised to use the following function:
+    (+) void SAI_DMACmd(SAI_Block_TypeDef* SAI_Block_x, FunctionalState NewState);
+  [..]
+  This section provides also functions allowing to
+   (+) Check the SAI Block enable status
+   (+)Check the FIFO status 
+   
+  *** SAI Block Enable status ***
+  ===============================
+  [..]
+  After disabling a SAI Block, it is recommended to check (or wait until) the SAI Block 
+  is effectively disabled. If a Block is disabled while an audio frame transfer is ongoing
+  the current frame will be transferred and the block will be effectively disabled only at 
+  the end of audio frame. 
+  To monitor this state it is possible to use the following function:
+    (+) FunctionalState SAI_GetCmdStatus(SAI_Block_TypeDef* SAI_Block_x); 
+ 
+  *** SAI Block FIFO status ***
+  =============================
+  [..]
+  It is possible to monitor the FIFO status when a transfer is ongoing using the following 
+  function:
+    (+) uint32_t SAI_GetFIFOStatus(SAI_Block_TypeDef* SAI_Block_x);
+

+       (PLL48CLK). Before to start working with SDIO peripheral make sure that the
+       PLL is well configured.
+       The SDIO peripheral uses two clock signals:
+       (++) SDIO adapter clock (SDIOCLK = 48 MHz)
+       (++) APB2 bus clock (PCLK2)
+       
+       -@@- PCLK2 and SDIO_CK clock frequencies must respect the following condition:
+           Frequency(PCLK2) >= (3 / 8 x Frequency(SDIO_CK))
+  
+   (#) Enable peripheral clock using RCC_APB2PeriphClockCmd(RCC_APB2Periph_SDIO, ENABLE).
+  
+   (#) According to the SDIO mode, enable the GPIO clocks using 
+       RCC_AHB1PeriphClockCmd() function. 
+       The I/O can be one of the following configurations:
+       (++) 1-bit data length: SDIO_CMD, SDIO_CK and D0.
+       (++) 4-bit data length: SDIO_CMD, SDIO_CK and D[3:0].
+       (++) 8-bit data length: SDIO_CMD, SDIO_CK and D[7:0].      
+  
+   (#) Peripheral alternate function: 
+       (++) Connect the pin to the desired peripherals' Alternate Function (AF) 
+           using GPIO_PinAFConfig() function
+       (++) Configure the desired pin in alternate function by: 
+           GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AF
+       (++) Select the type, pull-up/pull-down and output speed via GPIO_PuPd, 
+           GPIO_OType and GPIO_Speed members
+       (++) Call GPIO_Init() function
+  
+   (#) Program the Clock Edge, Clock Bypass, Clock Power Save, Bus Wide, 
+       hardware, flow control and the Clock Divider using the SDIO_Init()
+       function.
+  
+   (#) Enable the Power ON State using the SDIO_SetPowerState(SDIO_PowerState_ON) 
+       function.
+                
+   (#) Enable the clock using the SDIO_ClockCmd() function.
+  
+   (#) Enable the NVIC and the corresponding interrupt using the function 
+       SDIO_ITConfig() if you need to use interrupt mode. 
+  
+   (#) When using the DMA mode 
+       (++) Configure the DMA using DMA_Init() function
+       (++) Active the needed channel Request using SDIO_DMACmd() function
+  
+   (#) Enable the DMA using the DMA_Cmd() function, when using DMA mode. 
+  
+   (#) To control the CPSM (Command Path State Machine) and send 
+       commands to the card use the SDIO_SendCommand(), 
+       SDIO_GetCommandResponse() and SDIO_GetResponse() functions. First, user has
+       to fill the command structure (pointer to SDIO_CmdInitTypeDef) according 
+       to the selected command to be sent.
+       The parameters that should be filled are:

+       (++) Command Index
+       (++) Command Response type
+       (++) Command Wait
+       (++) CPSM Status (Enable or Disable).
+  
+       -@@- To check if the command is well received, read the SDIO_CMDRESP
+           register using the SDIO_GetCommandResponse().
+           The SDIO responses registers (SDIO_RESP1 to SDIO_RESP2), use the
+           SDIO_GetResponse() function.
+  
+   (#) To control the DPSM (Data Path State Machine) and send/receive 
+       data to/from the card use the SDIO_DataConfig(), SDIO_GetDataCounter(), 
+       SDIO_ReadData(), SDIO_WriteData() and SDIO_GetFIFOCount() functions.

+ ===================================================================
+                  ##### How to use this driver #####
+ ===================================================================
+ [..]
+   (#) Enable peripheral clock using the following functions 
+       RCC_APB2PeriphClockCmd(RCC_APB2Periph_SPI1, ENABLE) for SPI1
+       RCC_APB1PeriphClockCmd(RCC_APB1Periph_SPI2, ENABLE) for SPI2
+       RCC_APB1PeriphResetCmd(RCC_APB1Periph_SPI3, ENABLE) for SPI3
+       RCC_APB1PeriphResetCmd(RCC_APB1Periph_SPI3, ENABLE) for SPI4
+       RCC_APB1PeriphResetCmd(RCC_APB1Periph_SPI3, ENABLE) for SPI5
+       RCC_APB1PeriphResetCmd(RCC_APB1Periph_SPI3, ENABLE) for SPI6.
+  
+   (#) Enable SCK, MOSI, MISO and NSS GPIO clocks using RCC_AHB1PeriphClockCmd()
+       function. In I2S mode, if an external clock source is used then the I2S 
+       CKIN pin GPIO clock should also be enabled.
+  
+   (#) Peripherals alternate function: 
+       (++) Connect the pin to the desired peripherals' Alternate Function (AF) 
+            using GPIO_PinAFConfig() function
+       (++) Configure the desired pin in alternate function by: 
+            GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AF
+       (++) Select the type, pull-up/pull-down and output speed via GPIO_PuPd, 
+            GPIO_OType and GPIO_Speed members
+       (++) Call GPIO_Init() function In I2S mode, if an external clock source is 
+            used then the I2S CKIN pin should be also configured in Alternate 
+            function Push-pull pull-up mode. 
+          
+   (#) Program the Polarity, Phase, First Data, Baud Rate Prescaler, Slave 
+       Management, Peripheral Mode and CRC Polynomial values using the SPI_Init()
+       function.
+       In I2S mode, program the Mode, Standard, Data Format, MCLK Output, Audio 
+       frequency and Polarity using I2S_Init() function. For I2S mode, make sure 
+       that either:
+       (++) I2S PLL is configured using the functions 
+            RCC_I2SCLKConfig(RCC_I2S2CLKSource_PLLI2S), RCC_PLLI2SCmd(ENABLE) and 
+            RCC_GetFlagStatus(RCC_FLAG_PLLI2SRDY); or 
+       (++) External clock source is configured using the function 
+            RCC_I2SCLKConfig(RCC_I2S2CLKSource_Ext) and after setting correctly 
+            the define constant I2S_EXTERNAL_CLOCK_VAL in the stm32f4xx_conf.h file. 
+  
+   (#) Enable the NVIC and the corresponding interrupt using the function 
+       SPI_ITConfig() if you need to use interrupt mode. 
+  
+   (#) When using the DMA mode 
+       (++) Configure the DMA using DMA_Init() function
+       (++) Active the needed channel Request using SPI_I2S_DMACmd() function
+   
+   (#) Enable the SPI using the SPI_Cmd() function or enable the I2S using
+       I2S_Cmd().
+   
+   (#) Enable the DMA using the DMA_Cmd() function when using DMA mode. 
+  
+   (#) Optionally, you can enable/configure the following parameters without
+       re-initialization (i.e there is no need to call again SPI_Init() function):
+       (++) When bidirectional mode (SPI_Direction_1Line_Rx or SPI_Direction_1Line_Tx)
+            is programmed as Data direction parameter using the SPI_Init() function
+            it can be possible to switch between SPI_Direction_Tx or SPI_Direction_Rx
+            using the SPI_BiDirectionalLineConfig() function.
+       (++) When SPI_NSS_Soft is selected as Slave Select Management parameter 
+            using the SPI_Init() function it can be possible to manage the 
+            NSS internal signal using the SPI_NSSInternalSoftwareConfig() function.
+       (++) Reconfigure the data size using the SPI_DataSizeConfig() function  
+       (++) Enable or disable the SS output using the SPI_SSOutputCmd() function  
+            
+    (#) To use the CRC Hardware calculation feature refer to the Peripheral 
+        CRC hardware Calculation subsection.
+     
+  
+ [..] It is possible to use SPI in I2S full duplex mode, in this case, each SPI 
+      peripheral is able to manage sending and receiving data simultaneously
+      using two data lines. Each SPI peripheral has an extended block called I2Sxext
+      (ie. I2S2ext for SPI2 and I2S3ext for SPI3).
+      The extension block is not a full SPI IP, it is used only as I2S slave to
+      implement full duplex mode. The extension block uses the same clock sources
+      as its master.          
+      To configure I2S full duplex you have to:
+              
+      (#) Configure SPIx in I2S mode (I2S_Init() function) as described above. 
+             
+      (#) Call the I2S_FullDuplexConfig() function using the same strucutre passed to  
+          I2S_Init() function.
+              
+      (#) Call I2S_Cmd() for SPIx then for its extended block.
+            
+      (#) To configure interrupts or DMA requests and to get/clear flag status, 
+          use I2Sxext instance for the extension block.
+               
+ [..] Functions that can be called with I2Sxext instances are: I2S_Cmd(), 
+      I2S_FullDuplexConfig(), SPI_I2S_ReceiveData(), SPI_I2S_SendData(), 
+      SPI_I2S_DMACmd(), SPI_I2S_ITConfig(), SPI_I2S_GetFlagStatus(), 
+      SPI_I2S_ClearFlag(), SPI_I2S_GetITStatus() and SPI_I2S_ClearITPendingBit().
+                   
+      Example: To use SPI3 in Full duplex mode (SPI3 is Master Tx, I2S3ext is Slave Rx):
+              
+      RCC_APB1PeriphClockCmd(RCC_APB1Periph_SPI3, ENABLE);   
+      I2S_StructInit(&I2SInitStruct);
+      I2SInitStruct.Mode = I2S_Mode_MasterTx;     
+      I2S_Init(SPI3, &I2SInitStruct);
+      I2S_FullDuplexConfig(SPI3ext, &I2SInitStruct)
+      I2S_Cmd(SPI3, ENABLE);
+      I2S_Cmd(SPI3ext, ENABLE);
+      ...
+      while (SPI_I2S_GetFlagStatus(SPI2, SPI_FLAG_TXE) == RESET)
+      {}
+      SPI_I2S_SendData(SPI3, txdata[i]);
+      ...  
+      while (SPI_I2S_GetFlagStatus(I2S3ext, SPI_FLAG_RXNE) == RESET)
+      {}
+      rxdata[i] = SPI_I2S_ReceiveData(I2S3ext);
+      ...          
+                
+ [..]       
+   (@) In I2S mode: if an external clock is used as source clock for the I2S,  
+       then the define I2S_EXTERNAL_CLOCK_VAL in file stm32f4xx_conf.h should 
+       be enabled and set to the value of the source clock frequency (in Hz).
+   
+   (@) In SPI mode: To use the SPI TI mode, call the function SPI_TIModeCmd() 
+       just after calling the function SPI_Init().

+ ===============================================================================  
+
+ [..] This section provides a set of functions allowing to manage the SPI CRC hardware 
+      calculation
+
+ [..] SPI communication using CRC is possible through the following procedure:
+   (#) Program the Data direction, Polarity, Phase, First Data, Baud Rate Prescaler, 
+       Slave Management, Peripheral Mode and CRC Polynomial values using the SPI_Init()
+       function.
+   (#) Enable the CRC calculation using the SPI_CalculateCRC() function.
+   (#) Enable the SPI using the SPI_Cmd() function
+   (#) Before writing the last data to the TX buffer, set the CRCNext bit using the 
+       SPI_TransmitCRC() function to indicate that after transmission of the last 
+       data, the CRC should be transmitted.
+   (#) After transmitting the last data, the SPI transmits the CRC. The SPI_CR1_CRCNEXT
+        bit is reset. The CRC is also received and compared against the SPI_RXCRCR 
+        value. 
+        If the value does not match, the SPI_FLAG_CRCERR flag is set and an interrupt
+        can be generated when the SPI_I2S_IT_ERR interrupt is enabled.
+
+ [..]
+   (@) It is advised not to read the calculated CRC values during the communication.
+
+   (@) When the SPI is in slave mode, be careful to enable CRC calculation only 
+       when the clock is stable, that is, when the clock is in the steady state. 
+       If not, a wrong CRC calculation may be done. In fact, the CRC is sensitive 
+       to the SCK slave input clock as soon as CRCEN is set, and this, whatever 
+       the value of the SPE bit.
+
+   (@) With high bitrate frequencies, be careful when transmitting the CRC.
+       As the number of used CPU cycles has to be as low as possible in the CRC 
+       transfer phase, it is forbidden to call software functions in the CRC 
+       transmission sequence to avoid errors in the last data and CRC reception. 
+       In fact, CRCNEXT bit has to be written before the end of the transmission/reception 
+       of the last data.
+
+   (@) For high bit rate frequencies, it is advised to use the DMA mode to avoid the
+       degradation of the SPI speed performance due to CPU accesses impacting the 
+       SPI bandwidth.
+
+   (@) When the STM32F4xx is configured as slave and the NSS hardware mode is 
+       used, the NSS pin needs to be kept low between the data phase and the CRC 
+       phase.
+
+   (@) When the SPI is configured in slave mode with the CRC feature enabled, CRC
+       calculation takes place even if a high level is applied on the NSS pin. 
+       This may happen for example in case of a multi-slave environment where the 
+       communication master addresses slaves alternately.
+
+   (@) Between a slave de-selection (high level on NSS) and a new slave selection 
+       (low level on NSS), the CRC value should be cleared on both master and slave
+       sides in order to resynchronize the master and slave for their respective 
+       CRC calculation.
+
+   (@) To clear the CRC, follow the procedure below:
+       (#@) Disable SPI using the SPI_Cmd() function
+       (#@) Disable the CRC calculation using the SPI_CalculateCRC() function.
+       (#@) Enable the CRC calculation using the SPI_CalculateCRC() function.
+       (#@) Enable SPI using the SPI_Cmd() function.

+          function
+       
+      (#) Configure the TIM pins by configuring the corresponding GPIO pins
+       
+      (#) Configure the Time base unit as described in the first part of this driver,
+          if needed, else the Timer will run with the default configuration:
+        (++) Autoreload value = 0xFFFF
+        (++) Prescaler value = 0x0000
+        (++) Counter mode = Up counting
+        (++) Clock Division = TIM_CKD_DIV1
+          
+      (#) Fill the TIM_ICInitStruct with the desired parameters including:
+        (++) TIM Channel: TIM_Channel
+        (++) TIM Input Capture polarity: TIM_ICPolarity
+        (++) TIM Input Capture selection: TIM_ICSelection
+        (++) TIM Input Capture Prescaler: TIM_ICPrescaler
+        (++) TIM Input CApture filter value: TIM_ICFilter
+       
+      (#) Call TIM_ICInit(TIMx, &TIM_ICInitStruct) to configure the desired channel 
+          with the corresponding configuration and to measure only frequency 
+          or duty cycle of the input signal, or, Call TIM_PWMIConfig(TIMx, &TIM_ICInitStruct) 
+          to configure the desired channels with the corresponding configuration 
+          and to measure the frequency and the duty cycle of the input signal
+          
+      (#) Enable the NVIC or the DMA to read the measured frequency. 
+          
+      (#) Enable the corresponding interrupt (or DMA request) to read the Captured 
+          value, using the function TIM_ITConfig(TIMx, TIM_IT_CCx) 
+          (or TIM_DMA_Cmd(TIMx, TIM_DMA_CCx))

+    This subsection provides a set of functions allowing to initialize the USART 
+    in asynchronous and in synchronous modes.
+      (+) For the asynchronous mode only these parameters can be configured: 
+        (++) Baud Rate
+        (++) Word Length 
+        (++) Stop Bit
+        (++) Parity: If the parity is enabled, then the MSB bit of the data written
+             in the data register is transmitted but is changed by the parity bit.
+             Depending on the frame length defined by the M bit (8-bits or 9-bits),
+             the possible USART frame formats are as listed in the following table:
+   +-------------------------------------------------------------+     
+   |   M bit |  PCE bit  |            USART frame                |
+   |---------------------|---------------------------------------|             
+   |    0    |    0      |    | SB | 8 bit data | STB |          |
+   |---------|-----------|---------------------------------------|  
+   |    0    |    1      |    | SB | 7 bit data | PB | STB |     |
+   |---------|-----------|---------------------------------------|  
+   |    1    |    0      |    | SB | 9 bit data | STB |          |

+   +-------------------------------------------------------------+            
+        (++) Hardware flow control
+        (++) Receiver/transmitter modes
+
+    [..]
+    The USART_Init() function follows the USART  asynchronous configuration 
+    procedure (details for the procedure are available in reference manual (RM0090)).
+
+     (+) For the synchronous mode in addition to the asynchronous mode parameters these 
+         parameters should be also configured:
+        (++) USART Clock Enabled
+        (++) USART polarity
+        (++) USART phase
+        (++) USART LastBit
+

+ ===============================================================================  
+    [..]
+    This subsection provides a set of functions allowing to manage the USART 
+    IrDA communication.
+    [..]
+    IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
+    on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver 
+    is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
+    While receiving data, transmission should be avoided as the data to be transmitted
+    could be corrupted.
+    [..]
+    IrDA communication is possible through the following procedure:
+      (#) Program the Baud rate, Word length = 8 bits, Stop bits, Parity, Transmitter/Receiver 
+          modes and hardware flow control values using the USART_Init() function.
+      (#) Enable the USART using the USART_Cmd() function.
+      (#) Configures the IrDA pulse width by configuring the prescaler using  
+          the USART_SetPrescaler() function.
+      (#) Configures the IrDA  USART_IrDAMode_LowPower or USART_IrDAMode_Normal mode
+          using the USART_IrDAConfig() function.
+      (#) Enable the IrDA using the USART_IrDACmd() function.
+
+      -@- A pulse of width less than two and greater than one PSC period(s) may or may
+          not be rejected.
+      -@- The receiver set up time should be managed by software. The IrDA physical layer
+          specification specifies a minimum of 10 ms delay between transmission and 
+          reception (IrDA is a half duplex protocol).
+      -@- In IrDA mode, the following bits must be kept cleared:
+        (+@) LINEN, STOP and CLKEN bits in the USART_CR2 register.
+        (+@) SCEN and HDSEL bits in the USART_CR3 register.

+    This subsection provides a set of functions allowing to configure the USART

+    The user should identify which mode will be used in his application to manage 
+    the communication: Polling mode, Interrupt mode or DMA mode. 
+    
+    *** Polling Mode ***
+    ====================
+    [..]
+    In Polling Mode, the SPI communication can be managed by 10 flags:
+      (#) USART_FLAG_TXE : to indicate the status of the transmit buffer register
+      (#) USART_FLAG_RXNE : to indicate the status of the receive buffer register

+      (+) void USART_ClearFlag(USART_TypeDef* USARTx, uint16_t USART_FLAG);
+
+    *** Interrupt Mode ***
+    ======================
+    [..]
+    In Interrupt Mode, the USART communication can be managed by 8 interrupt sources
+    and 10 pending bits:

+        (##) USART_IT_TXE : specifies the interrupt source for the Tx buffer empty 
+                            interrupt. 
+        (##) USART_IT_RXNE : specifies the interrupt source for the Rx buffer not 
+                             empty interrupt.
+        (##) USART_IT_TC : specifies the interrupt source for the Transmit complete 
+                           interrupt. 
+        (##) USART_IT_IDLE : specifies the interrupt source for the Idle Line interrupt.

+        (##) USART_IT_LBD : specifies the interrupt source for the LIN break detection
+                            interrupt.

+        (##) USART_IT_ERR :  specifies the interrupt source for the errors interrupt.
+
+      -@@- Some parameters are coded in order to use them as interrupt source 
+          or as pending bits.
+    [..]
+    In this Mode it is advised to use the following functions:

+
+    *** DMA Mode ***
+    ================
+    [..]
+    In DMA Mode, the USART communication can be managed by 2 DMA Channel requests:
+      (#) USART_DMAReq_Tx: specifies the Tx buffer DMA transfer request
+      (#) USART_DMAReq_Rx: specifies the Rx buffer DMA transfer request
+    [..]
+    In this Mode it is advised to use the following function:

+                           ##### WWDG features #####
+ ===============================================================================
+    [..]                                      
+        Once enabled the WWDG generates a system reset on expiry of a programmed
+        time period, unless the program refreshes the counter (downcounter) 
+        before to reach 0x3F value (i.e. a reset is generated when the counter
+        value rolls over from 0x40 to 0x3F). 
+        An MCU reset is also generated if the counter value is refreshed
+        before the counter has reached the refresh window value. This 
+        implies that the counter must be refreshed in a limited window.
+              
+        Once enabled the WWDG cannot be disabled except by a system reset.                          
+          
+        WWDGRST flag in RCC_CSR register can be used to inform when a WWDG
+        reset occurs.
+             
+        The WWDG counter input clock is derived from the APB clock divided 
+        by a programmable prescaler.
+                
+        WWDG counter clock = PCLK1 / Prescaler
+        WWDG timeout = (WWDG counter clock) * (counter value)
+                       
+        Min-max timeout value @42 MHz(PCLK1): ~97.5 us / ~49.9 ms
+                             
+                      ##### How to use this driver #####
+ ===============================================================================
+    [..]
+      (#) Enable WWDG clock using RCC_APB1PeriphClockCmd(RCC_APB1Periph_WWDG, ENABLE) function
+              
+      (#) Configure the WWDG prescaler using WWDG_SetPrescaler() function
+                             
+      (#) Configure the WWDG refresh window using WWDG_SetWindowValue() function
+              
+      (#) Set the WWDG counter value and start it using WWDG_Enable() function.
+          When the WWDG is enabled the counter value should be configured to 
+          a value greater than 0x40 to prevent generating an immediate reset.     
+              
+      (#) Optionally you can enable the Early wakeup interrupt which is 
+          generated when the counter reach 0x40.
+          Once enabled this interrupt cannot be disabled except by a system reset.
+                  
+      (#) Then the application program must refresh the WWDG counter at regular
+          intervals during normal operation to prevent an MCU reset, using
+          WWDG_SetCounter() function. This operation must occur only when
+          the counter value is lower than the refresh window value, 
+          programmed using WWDG_SetWindowValue().

+  * @brief   This file provides the high layer firmware functions to manage the 
+  *          following functionalities of the USB Audio Class:
+  *           - Initialization and Configuration of high and low layer
+  *           - Enumeration as Audio Streaming Device
+  *           - Audio Streaming data transfer
+  *           - AudioControl requests management
+  *           - Error management
+  *           
+  *  @verbatim
+  *      
+  *          ===================================================================      
+  *                                Audio Class Driver Description
+  *          =================================================================== 
+  *           This driver manages the Audio Class 1.0 following the "USB Device Class Definition for
+  *           Audio Devices V1.0 Mar 18, 98".
+  *           This driver implements the following aspects of the specification:
+  *             - Device descriptor management
+  *             - Configuration descriptor management
+  *             - Standard AC Interface Descriptor management
+  *             - 1 Audio Streaming Interface (with single channel, PCM, Stereo mode)
+  *             - 1 Audio Streaming Endpoint
+  *             - 1 Audio Terminal Input (1 channel)
+  *             - Audio Class-Specific AC Interfaces
+  *             - Audio Class-Specific AS Interfaces
+  *             - AudioControl Requests: only SET_CUR and GET_CUR requests are supported (for Mute)
+  *             - Audio Feature Unit (limited to Mute control)
+  *             - Audio Synchronization type: Asynchronous
+  *             - Single fixed audio sampling rate (configurable in usbd_conf.h file)
+  *          
+  *           @note
+  *            The Audio Class 1.0 is based on USB Specification 1.0 and thus supports only
+  *            Low and Full speed modes and does not allow High Speed transfers.
+  *            Please refer to "USB Device Class Definition for Audio Devices V1.0 Mar 18, 98"
+  *            for more details.
+  * 
+  *           These aspects may be enriched or modified for a specific user application.
+  *          
+  *            This driver doesn't implement the following aspects of the specification 
+  *            (but it is possible to manage these features with some modifications on this driver):
+  *             - AudioControl Endpoint management
+  *             - AudioControl requsests other than SET_CUR and GET_CUR
+  *             - Abstraction layer for AudioControl requests (only Mute functionality is managed)
+  *             - Audio Synchronization type: Adaptive
+  *             - Audio Compression modules and interfaces
+  *             - MIDI interfaces and modules
+  *             - Mixer/Selector/Processing/Extension Units (Feature unit is limited to Mute control)
+  *             - Any other application-specific modules
+  *             - Multiple and Variable audio sampling rates
+  *             - Out Streaming Endpoint/Interface (microphone)
+  *

+  * @brief   This file provides the high layer firmware functions to manage the 
+  *          following functionalities of the USB CDC Class:
+  *           - Initialization and Configuration of high and low layer
+  *           - Enumeration as CDC Device (and enumeration for each implemented memory interface)
+  *           - OUT/IN data transfer
+  *           - Command IN transfer (class requests management)
+  *           - Error management
+  *

+  *          ===================================================================      
+  *                                CDC Class Driver Description
+  *          =================================================================== 
+  *           This driver manages the "Universal Serial Bus Class Definitions for Communications Devices
+  *           Revision 1.2 November 16, 2007" and the sub-protocol specification of "Universal Serial Bus 
+  *           Communications Class Subclass Specification for PSTN Devices Revision 1.2 February 9, 2007"
+  *           This driver implements the following aspects of the specification:
+  *             - Device descriptor management
+  *             - Configuration descriptor management
+  *             - Enumeration as CDC device with 2 data endpoints (IN and OUT) and 1 command endpoint (IN)
+  *             - Requests management (as described in section 6.2 in specification)
+  *             - Abstract Control Model compliant
+  *             - Union Functional collection (using 1 IN endpoint for control)
+  *             - Data interface class
+
+  *           @note
+  *             For the Abstract Control Model, this core allows only transmitting the requests to
+  *             lower layer dispatcher (ie. usbd_cdc_vcp.c/.h) which should manage each request and
+  *             perform relative actions.
+  * 
+  *           These aspects may be enriched or modified for a specific user application.
+  *          
+  *            This driver doesn't implement the following aspects of the specification 
+  *            (but it is possible to manage these features with some modifications on this driver):
+  *             - Any class-specific aspect relative to communication classes should be managed by user application.
+  *             - All communication classes other than PSTN are not managed
+  *

+  * @brief   This file provides the high layer firmware functions to manage the 
+  *          following functionalities of the USB DFU Class:
+  *           - Initialization and Configuration of high and low layer
+  *           - Enumeration as DFU Device (and enumeration for each implemented memory interface)
+  *           - Transfers to/from memory interfaces
+  *           - Easy-to-customize "plug-in-like" modules for adding/removing memory interfaces.
+  *           - Error management
+  *           
+  *  @verbatim
+  *      
+  *          ===================================================================      
+  *                                DFU Class Driver Description
+  *          =================================================================== 
+  *           This driver manages the DFU class V1.1 following the "Device Class Specification for 
+  *           Device Firmware Upgrade Version 1.1 Aug 5, 2004".
+  *           This driver implements the following aspects of the specification:
+  *             - Device descriptor management
+  *             - Configuration descriptor management
+  *             - Enumeration as DFU device (in DFU mode only)
+  *             - Requests management (supporting ST DFU sub-protocol)
+  *             - Memory operations management (Download/Upload/Erase/Detach/GetState/GetStatus)
+  *             - DFU state machine implementation.
+  *          
+  *           @note
+  *            ST DFU sub-protocol is compliant with DFU protocol and use sub-requests to manage
+  *            memory addressing, commands processing, specific memories operations (ie. Erase) ...
+  *            As required by the DFU specification, only endpoint 0 is used in this application.
+  *            Other endpoints and functions may be added to the application (ie. DFU ...)
+  * 
+  *           These aspects may be enriched or modified for a specific user application.
+  *          
+  *           This driver doesn't implement the following aspects of the specification 
+  *           (but it is possible to manage these features with some modifications on this driver):
+  *             - Manifestation Tolerant mode
+  *

+*
+*  (iii) TXn min size = 16 words. (n  : Transmit FIFO index)
+*   (iv) When a TxFIFO is not used, the Configuration should be as follows:

+*       --> Txn should be configured with the minimum space of 16 words
+*  (v) The FIFO is used optimally when used TxFIFOs are allocated in the top
+*       of the FIFO.Ex: use EP1 and EP2 as IN instead of EP1 and EP3 as IN ones
