Receive an amount of data in blocking mode using HAL_I2S_Receive()
Interrupt mode IO operation
Send an amount of data in non blocking mode using HAL_I2S_Transmit_IT()
At transmission end of half transfer HAL_I2S_TxHalfCpltCallback is executed and
user can add his own code by customization of function pointer

Pause the DMA Transfer using HAL_I2S_DMAPause()
Resume the DMA Transfer using HAL_I2S_DMAResume()
Stop the DMA Transfer using HAL_I2S_DMAStop()
I2S HAL driver macros list
Below the list of most used macros in USART HAL driver.
__HAL_I2S_ENABLE: Enable the specified SPI peripheral (in I2S mode)
__HAL_I2S_DISABLE: Disable the specified SPI peripheral (in I2S mode)
__HAL_I2S_ENABLE_IT : Enable the specified I2S interrupts
__HAL_I2S_DISABLE_IT : Disable the specified I2S interrupts
__HAL_I2S_GET_FLAG: Check whether the specified I2S flag is set or not
You can refer to the I2S HAL driver header file for more useful macros
