Detailed Description

A digital interrupt input, used to call a function on a rising or falling edge.

Synchronization level: Interrupt safe

Example: 

 // Flash an LED while waiting for events

 #include "mbed.h"

 InterruptIn event(p16);
 DigitalOut led(LED1);

 void trigger() {
     printf("triggered!\n");
 }

 int main() {
     event.rise(&trigger);
     while(1) {
         led = !led;
         wait(0.25);
     }
 }
