Hi,

I am completely new to the st family of microcontrollers and an amateur.

Before I had my setup running with an esp32 but I just missed the performance I need so I switched. I tried to configure within cubemx and import into platformio for furher development

I want to connect three audiodevices using i2s (2 receive, 1 send) with the stm generating the necessary clocks for it and I am really struggleing to do so. I want to run 48 kHz and was wondering if you have any ideas how to set it up properly. Thanks for helping

I just ordered a WaveShare CoreH743I STM32 MCU Core Board STM32H743IIT6 JTAG/SWD Debug Interface (WS16635)

I hope that this will di better. There is a 8mHz crystal on board and I think I should be able to use the settings from the post above.

Really looking forward to it as I had two nights with a terrible sounding 500 Hz testtone  running all the time sounding completely off due to sync issues. I
