[#1]

Here you can find the code and project files for the Interrupt example, in this example 2 KBI interrupts are enabled, one assigned to SW2 and another to SW3, during the main routine the blue led is turned on, when the interrupt routines are triggered the blue led is turned off and the red or green led blink once, the interrupt was configured to detect falling edges only.

Code:

#include "mbed.h"

InterruptIn Interrupt(SW2);

void blink()

{

    wait(.4);

    Red=1;

    Blue=0;
