void	ACCELERO_IO_Read (uint8_t *pBuffer, uint8_t ReadAddr, uint16_t NumByteToRead)
	Reads a block of data from the Accelerometer. More...
void	ACCELERO_IO_Write (uint8_t *pBuffer, uint8_t WriteAddr, uint16_t NumByteToWrite)
	Writes one byte to the Accelerometer. More...
void	AUDIO_IO_DeInit (void)
	DeInitializes Audio low level. More...
void	AUDIO_IO_Init (void)
	Initializes Audio low level. More...
uint8_t	AUDIO_IO_Read (uint8_t Addr, uint8_t Reg)
	Reads a single data. More...
void	AUDIO_IO_Write (uint8_t Addr, uint8_t Reg, uint8_t Value)
	Writes a single data. More...
uint32_t	BSP_GetVersion (void)
	This method returns the STM32F4 DISCO BSP Driver revision. More...
void	BSP_LED_Init (Led_TypeDef Led)
	Configures LED GPIO. More...
void	BSP_LED_Off (Led_TypeDef Led)
	Turns selected LED Off. More...
void	BSP_LED_On (Led_TypeDef Led)

void	BSP_LED_Toggle (Led_TypeDef Led)
	Toggles the selected LED. More...
uint32_t	BSP_PB_GetState (Button_TypeDef Button)
	Returns the selected Button state. More...
void	BSP_PB_Init (Button_TypeDef Button, ButtonMode_TypeDef Mode)
	Configures Button GPIO and EXTI Line. More...
static void	I2Cx_Error (uint8_t Addr)
	Manages error callback by re-initializing I2C. More...
static void	I2Cx_Init (void)
	Configures I2C interface. More...
static void	I2Cx_MspInit (void)
	I2C MSP Initialization. More...
static uint8_t	I2Cx_ReadData (uint8_t Addr, uint8_t Reg)
	Read a register of the device through BUS. More...
static void	I2Cx_WriteData (uint8_t Addr, uint8_t Reg, uint8_t Value)
	Write a value in a register of the device through BUS. More...
static void	SPIx_Error (void)
	SPIx error treatment function. More...
static void	SPIx_Init (void)
	SPIx Bus initialization. More...
static void	SPIx_MspInit (void)
	SPI MSP Init. More...
static uint8_t	SPIx_WriteRead (uint8_t Byte)
