STM32F7 I2S Timeout, clock generation

[bsgursta]

I am using an STM32F7 Nucleo Board with SPI/I2S to get audio data from this MEMS microphone.

https://www.adafruit.com/product/6049?gad_campaignid=21079227318gad_campaignid=21079227318

 

I am having issues with none of the signals triggering: WS, CLK, or Data.

I call the HAL_I2S_Receive function, and neither the clock nor the select signal is triggered. I enter the timeout checker and only leave once I have timed out.

If anyone has any suggestions? I have my DAD connected, and I see nothing.

Hello @bsgursta 

Try disable the I2S, then enable it again upon detecting the correct signals.

Did you check the known limitations in the errata sheet of your product?
