STM32L4S9 SAI Configuration Full Duplex

NKara.3 · ‎2021-08-24

Hi,

I would like to use the SAI as full duplex slave mode with I2S/PCM protocol.

I'm not sure about the configuration and which pins are TX and RX when using Cube.

In the parameter I can set the audio to transmit or receive.

In this case SAI_SD_A will be transmit and SAI_SD_B receive?
