Functions
uint8_t	BSP_AUDIO_OUT_Init (uint16_t OutputDevice, uint8_t Volume, uint32_t AudioFreq)
	Configures the audio peripherals. More...

void	BSP_AUDIO_OUT_DeInit (void)
	De-initializes the audio out peripheral. More...

uint8_t	BSP_AUDIO_OUT_Play (uint16_t *pBuffer, uint32_t Size)
	Starts playing audio stream from a data buffer for a determined size. More...

void	BSP_AUDIO_OUT_Restart (uint16_t *pBuffer, uint32_t Size)

void	BSP_AUDIO_OUT_ChangeBuffer (uint16_t *pData, uint16_t Size)
	Sends n-Bytes on the SAI interface. More...

uint8_t	BSP_AUDIO_OUT_Pause (void)
	This function Pauses the audio file stream. In case of using DMA, the DMA Pause feature is used. When calling BSP_AUDIO_OUT_Pause() function for pause, only BSP_AUDIO_OUT_Resume() function should be called for resume (use of BSP_AUDIO_OUT_Play() function for resume could lead to unexpected behavior). More...

uint8_t	BSP_AUDIO_OUT_Resume (void)
	Resumes the audio file stream. When calling BSP_AUDIO_OUT_Pause() function for pause, only BSP_AUDIO_OUT_Resume() function should be called for resume (use of BSP_AUDIO_OUT_Play() function for resume could lead to unexpected behaviour). More...

uint8_t	BSP_AUDIO_OUT_Stop (uint32_t Option)
	Stops audio playing and Power down the Audio Codec. More...

uint8_t	BSP_AUDIO_OUT_SetVolume (uint8_t Volume)

	Updates the audio frequency. More...

void	BSP_AUDIO_OUT_SetAudioFrameSlot (uint32_t AudioFrameSlot)
	Updates the Audio frame slot configuration. More...

uint8_t	BSP_AUDIO_OUT_SetMute (uint32_t Cmd)
	Enables or disables the MUTE mode by software. More...

uint8_t	BSP_AUDIO_OUT_SetOutputMode (uint8_t Output)
	Switch dynamically (while audio file is played) the output target (speaker or headphone). More...

void	BSP_AUDIO_OUT_TransferComplete_CallBack (void)
	Calculates the remaining file size and new position of the pointer. More...

void	BSP_AUDIO_OUT_HalfTransfer_CallBack (void)
	Manages the DMA Half Transfer complete interrupt. More...

void	BSP_AUDIO_OUT_Error_CallBack (void)
	Manages the DMA FIFO error event. More...

void	BSP_AUDIO_OUT_ClockConfig (SAI_HandleTypeDef hsai, uint32_t AudioFreq, void Params)
	Clock Config. More...

uint8_t	BSP_AUDIO_IN_Record (uint16_t *pData, uint32_t Size)
	Start audio recording. More...

uint8_t	BSP_AUDIO_IN_Stop (void)
	Stop audio recording. More...

uint8_t	BSP_AUDIO_IN_Pause (void)
	Pause the audio file stream. More...

uint8_t	BSP_AUDIO_IN_Resume (void)
	Resume the audio file stream. More...

void	BSP_AUDIO_IN_TransferComplete_CallBack (void)
	User callback when record buffer is filled. More...

void	BSP_AUDIO_IN_HalfTransfer_CallBack (void)
	Manages the DMA Half Transfer complete event. More...

void	BSP_AUDIO_IN_Error_CallBack (void)
	Audio IN Error callback function. More...

void	BSP_AUDIO_IN_ClockConfig (DFSDM_Filter_HandleTypeDef hdfsdm_filter, uint32_t AudioFreq, void Params)
	Clock Config. More...

void	BSP_AUDIO_IN_MspInit (void)
