Looking for an example of STM32H7 using I2S for micro_speech

[Michael O'Cleirigh]

Hello, 

For my microypython firmware we are using an I2S abstraction layer for implementing micro_speech.  It works for ESP32, RP2040 and STM32F4 and STM32F7.

I found out when trying to compile for my STM32H743ZI2 that there are HAL differences and it doesn't work.

I thought I would ask here if anyone knows of an implementation of the micro_speech example on an STM32H7 that I could copy from to see how the H7 HAL works for I2S.

Thanks, 

Michael
