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.
