STM32G431KB (Nucleo32 Board) USART Example with Autobaud or a how-to

Heinrich · ‎2023-07-24

hello together,

I would use a Nucleo-32 board in my new project, the Nucleo-G431KB. In this project I would like to use the autobaud feature. Only I can't find an example, there are many USART examples but none with autobaud.

Does anyone have an example or a small HowTo?

Thanks a lot!

Hello @Heinrich ,

you can check the application note AN4908: https://www.st.com/resource/en/application_note/an4908-stm32-usart-automatic-baud-rate-detection-stmicroelectronics.pdf

The G4 serie is not mentioned there, however the code should be applicable on it as well, as the principle is still the same.

BR,
Jaroslav

The G4 serie is not mentioned there,

That was July last year.

2024 updates have added G4, among others:
