This patch introduces an example application to demonstrate how to use GPIO driver APIs to manipulate output pins. The application sets the GPIO 4 pin as output pin and toggles its state at every half second.

Galileo Specific Examples
|
|
=======================
|
|
|
|
This directory contains galileo-specific example applications to illustrate
|
|
how to use galileo APIs.
|
|
|
|
In order to build a application, you should set the EXAMPLE environment
|
|
variable to the name of the application you want to build. For instance, if
|
|
you want to build gpio-output application, run the following command:
|
|
$ make TARGET=galileo EXAMPLE=gpio-output
|

GPIO Output
|
|
===========
|
|
|
|
This application shows how to use the GPIO driver APIs to manipulate output
|
|
pins. This application sets the GPIO 4 pin as output pin and toggles its
|
|
state at every half second.
|
|
|
|
For a visual effect, you should wire shield pin IO1 to a led in a protoboard.
|
|
Once the application is running, you should see a blinking LED.
