This simple firmare toggles the LED on the STM32F429I-DISC1 discovery board.
#include <mbed.h> DigitalOut myled(LED1); int main() { while(1) { myled = !myled; wait(0.5); } }
This will toggle the green (PG13) LED twice per second.
The program is simple: We toggle the LED using myled = !myled;
and then use wait(0.5)
for 0.5 seconds.
