Example Description

This example describes how to use GPIO read/write by mbed api.

Requirement Components:
    a LED
    a push button

Pin name PC_4 and PC_5 map to GPIOC_4 and GPIOC_5:
 - PC_4 as input with internal pull-high, connect a push button to this pin and ground.
 - PC_5 as output, connect a LED to this pin and ground.

In this example, push the button to trigger interrupt to turn on/off the LED.
