# GPIO examples

This directory contains examples to showcase the features and the use of io's
GPIO subsystem.

## input

This example configures a GPIO pin as an interrupt source. To try this with
your hardware, connect the GPIO pin to ground. To issue the interrupt
disconnect it from ground.

## led

This example uses a GPIO pin to turn an LED on and off. Either your hardware
has a user-configurable LED connected via GPIO or you can easily build this on
your own using a bread board.
