Hi everyone,Figured I banged my head against a wall long enough, so might as well ask even if it is a really simple fix.So far I have only used USART2 to write data to the Virtual COM port from my nucleo board, now I have need to write other data out...

Thank you for the replies JW, much appreciated for the help you are giving trying to fix this!I double checked the baudrate as well as the wired connections and ensured it is all hooked up correctly, but my main concern here is the ability to transmi...

Spent most of the day debugging, to respond to the USART and GPIO Registers:Both USART1(Not working) and USART2(Working) Registers have very simlar inits. They have the same nonzero values of BRR, TDR, the only nonzero value that differentiates is th...

1) I stripped my code to the bare minimum, only have UART1 initialized, no other UART or GPIO pins.2) Any pointers on how to check/compare/post the USART and relevant GPIO register content? I have the register values as I step through the code but i ...
