Detailed Description

I2SEx IO operation functions.

 ===============================================================================

 ===============================================================================
    [..]
    This subsection provides a set of functions allowing to manage the I2S data
    transfers.

    (#) There are two modes of transfer:
       (++) Blocking mode : The communication is performed in the polling mode.
            The status of all data processing is returned by the same function
            after finishing transfer.
       (++) No-Blocking mode : The communication is performed using Interrupts
            or DMA. These functions return the status of the transfer startup.
            The end of the data processing will be indicated through the
            dedicated I2S IRQ when using Interrupt mode or the DMA IRQ when
            using DMA mode.

    (#) Blocking mode functions are :
        (++) HAL_I2SEx_TransmitReceive()

    (#) No-Blocking mode functions with Interrupt are :
        (++) HAL_I2SEx_TransmitReceive_IT()
        (++) HAL_I2SEx_FullDuplex_IRQHandler()

    (#) No-Blocking mode functions with DMA are :
        (++) HAL_I2SEx_TransmitReceive_DMA()

    (#) A set of Transfer Complete Callback are provided in non Blocking mode:
        (++) HAL_I2SEx_TxRxCpltCallback()

HAL_StatusTypeDef HAL_I2SEx_TransmitReceive	(	I2S_HandleTypeDef *	hi2s,
		uint16_t *	pTxData,
		uint16_t *	pRxData,
		uint16_t	Size,
		uint32_t	Timeout
	)

Full-Duplex Transmit/Receive data in blocking mode.

Parameters:

hi2s	pointer to a I2S_HandleTypeDef structure that contains the configuration information for I2S module
pTxData	a 16-bit pointer to the Transmit data buffer.
pRxData	a 16-bit pointer to the Receive data buffer.
Size	number of data sample to be sent:

Note:: When a 16-bit data frame or a 16-bit data frame extended is selected during the I2S configuration phase, the Size parameter means the number of 16-bit data length in the transaction and when a 24-bit data frame or a 32-bit data frame is selected the Size parameter means the number of 16-bit data length.

Parameters:

Timeout Timeout duration

Note:: The I2S is kept enabled at the end of transaction to avoid the clock de-synchronization between Master and Slave(example: audio streaming).

Return values:

HAL status
