STM32CubeIDE Error / bug

[StanCosgrove]

Hi 

 I m working on NUCLEO-H723 Board,  was programming SPI and is working fine, when trying to add USART function to display text on serial terminal and encountered the following errors, unable to make sense what went wrong, anyone can help ? thx.

I would say you're posting in the wrong forum, but there's actually no description anywhere on what the "Feedback Forum" is for.

Historically, the feedback forum is not meant for technical questions.

>> multiple definition of `huart3';

So DON'T do that. Create the instance in one file, make extern references in others, and in include files, etc.

Hello @TDK , 

Well noted. The description is now in place!

Thanks,
