Jonathan Gaul / DigitalOutEx

Provides an extended version of DigitalOut that adds a "toggle()" function, and uses the RTOS Thread API to provide a "flash()" function that toggles the pin in the background at a given interval.

Dependents:   Car_Simulator

Example of use:

#include "mbed.h"
#include "rtos.h"    /* NOTE: Requires the RTOS library or a matching API */
#include "DigitalOutEx.h"

DigitalOutEx led1(LED1);
DigitalOutEx led2(LED2);

int main() {
    
    led1.flash(200);
    led2.flash(500);
    
    Thread::wait(5000);
    
    led1.flash(50);
    
    Thread::wait(5000);
    
    led1 = 0;
    
    Thread::wait(5000);
    
    led1.flash(1000);
    
    while (1) { }    
}
