Hi,

Can anyone point me to an example code of using the Serial Audio Interface for the STM32F429? I have a 32F429IDISCOVERY and wish to connect an 8 channel audio

ADC using the CS5368 which requires TDM. I am looking at the STM32Cube_FW_F4_V1.3.0 HAL, and noticed that there are no examples for SAI for the STM32F429I-Discovery. I'd appreciate any pointers. Thanks a lot in advance!

Hi,

In fact the only SAI peripheral example is based on the STM324x9I_EVAL board under the STM32Cube_FW_F4_V1.3.0, since this board embedds already the external codec WM8994, supporting the TDM format.

Thus, you can't use the SAI peripheral for an audio application without any available codec hardware layer, which is the case of the STM32F429I-Discovery board. 

Cheers,

Heisenberg.

Thank you. That's just what I need. yes, we will be using our own external hardware codec.
