====== How to use Cubieboard-GPIO On Android======

We use gpio-contrl code and some library files to compile an executable file named gpio-ctrl so that we can control the GPIO pin by Android app. 

First we need to download the gpio-app from here [[http://ubuntuone.com/5VcumJ1O27WZaUamC4lpMV]] and decompress it. There are two files in the gpio-app directory.

Connect the Cubieboard by USB and then open a terminal and type:

  $ adb shell
  $ mount -o remount,rw /system
  $ exit
  $ adb push gpio-ctrl /system/bin  
  
Download the app into Cubieboard:

  $ adb install CB-GPIO-beta1.apk
  
Now we can control the GPIO by CB-GPIO, to do something interesting.
  
Note: We just use PD0~PD27 pins.
