Getting STM32 Nucleo F030R8 to communicate with RX and TX pins

I'm having issues trying to get this Nucleo to send commands or receive commands using the online mbed compiler. As a starter step, I am trying to connect the rx and tx pin on my Nucleo to try to send a command to itself and display it using serial display. Could anyone provide some assistance in the matter? I seem to be getting nowhere on this and online searches haven't yielded many promising results.


  • I figured it out, there are 2 UARTS, I was using the first one and that one was being used by the USBTX and USBRX. So i just used pins D2 and D8, the UART2 pins so there was no conflict.
