    Hello, I finally got my STM32-P103 running but I want to make a code that detects where there is some data coming in from the RS232 port or not, so the idea is to make the LED flash any time there is a message coming in.
    At the moment Im just re-writing the main.c file from the example file that make the LED flash.

    Any help would be welcome! thanks!

    This looks like a nice development/prototype board. I found the documentation
    on the board (and the processor) at:

    I believe the WKUP and other related I/O pins are software programmable to
    interrupt on edge detection. This interrupt would alert the software to respond,
    and the Interrupt Service Routine (ISR) could blink the LED.
