Description

This is a very generic example of what all ‘blink’ type programs start with. Unlike the hello.c example it cannot rely on standard libraries in the C language to function, instead there are always some particular things that need to be done on the specific system it is targeting.

Sometimes those are built in, like the Arduino Blink example, and other times you have to write that code yourself from information in the data sheets.

The Source Code

#include <custom-include-file.h>

void main() {
    initialize_io_pin(LED_PIN, OUTPUT_PIN);

    while (1) {
        toggle_io_pin(LED_PIN);
        delay(1000);
    }
}
