uart

#include "mbed.h"
 
DigitalOut led1(LED1);
DigitalOut led2(LED2);
 
Serial pc(USBTX, USBRX);
 
void callback() {
    // Note: you need to actually read from the serial to clear the RX interrupt
    printf("%c\n", pc.getc());
    led2 = !led2;
}
 
int main() {
    pc.attach(&callback);
    
    while (1) {
        led1 = !led1;
        wait(0.5);
    }
