Configure USART 2 on STM32F4

Recommended Posts

Found this in my STM32 adventures. Keeping it here if anyone finds it useful. He has some more cool stuff. Check out his site.


I wrote a nice simple piece of code that will configure USART2 on PD5(tx) and PD6(rx). Works like a charm For me so far at least. APBClock is 1/8 my clock… if this doesn’t work its usually a incorrect clock setting.
