I2S under STM32CubeIde on Nucleo144 STM32F767ZI not generating clock or word select signals !

[L77d]

Hi,

Still attempting to work with STM32F767ZI board to generate signals to manage I2S mic (INMP441)

I have followed many recommendations, even used MX, but still no clock nor word select signals are generated from MCU....

But throu GPIO I can generate a clean square signal ?! So ?

Did I miss a thing ?

Thx very much for your help

Hello @L77d 

Check your STM32F767ZI-Nucleo Set-up and configuration within the available example (check recommendations in the readme file), then update the project according to your needs:
