RT1062 SAI EDMA Using Same Callback For both TX & RX?

It is possible for us to use only one callback for EDMA TX and RX? Currently the callbacks for SAI EDMA callback is separated into two callbacks.

Hi @vincentmokrc ,

Thanks for your interest in NXP MIMXRT series!

Yes, you can do this. Tx and Rx can be decoupled by using the passed *userData. e.g. when creating SAI EDMA handles, pass in different userData for TX and RX respectively, such as the addresses of txHandle and rxHandle.

Best regards,
Gavin
