The Timeout interface is used to setup an interrupt to call a function after a specified delay.

Any number of Timeout objects can be created, allowing multiple outstanding interrupts at the same time.

Hello World!

A simple program to setup a Timeout to invert an LED after a given timeout...

#include "mbed.h"

Timeout flipper;
DigitalOut led1(LED1);
DigitalOut led2(LED2);

void flip() {
    led2 = !led2;
}

int main() {
    led2 = 1;
    flipper.attach(&flip, 2.0); // setup flipper to call flip after 2 seconds

    // spin in a main loop. flipper will interrupt it to call flip
    while(1) {
        led1 = !led1;
        wait(0.2);
    }
}
