Data transfers functions.
===============================================================================
##### 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_I2S_Transmit()
(++) HAL_I2S_Receive()
(++) HAL_I2SEx_TransmitReceive()
(#) No-Blocking mode functions with Interrupt are :
(++) HAL_I2S_Transmit_IT()
(++) HAL_I2S_Receive_IT()
(++) HAL_I2SEx_TransmitReceive_IT()
(#) No-Blocking mode functions with DMA are :
(++) HAL_I2S_Transmit_DMA()
(++) HAL_I2S_Receive_DMA()
(++) HAL_I2SEx_TransmitReceive_DMA()
(#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
(++) HAL_I2S_TxCpltCallback()
(++) HAL_I2S_RxCpltCallback()
(++) HAL_I2SEx_TxRxCpltCallback()
(++) HAL_I2S_ErrorCallback()
Receive an amount of data in blocking mode.
- Parameters:
-
| hi2s | pointer to a I2S_HandleTypeDef structure that contains the configuration information for I2S module |
| pData | a 16-bit pointer to 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:
-
- Note:
- The I2S is kept enabled at the end of transaction to avoid the clock de-synchronization between Master and Slave(example: audio streaming).
-
In I2S Master Receiver mode, just after enabling the peripheral the clock will be generate in continuous way and as the I2S is not disabled at the end of the I2S transaction.
- Return values:
