Basic Accessory Demo

Example app on how to interface from an Android device to an accessory

This demo provides a simple example on how to interface from an Android device to an accessory using the Open Accessory framework added in v2.3.4+ and v3.1+ versions of the Android OS. The demo controls 8 LEDs on the board by touching the LED pictures on the screen, indicates the push button status of the board, and provides a percentage indication of the potentiometer. This demo also only shows how to use the host mode accessory implementation using the API10 android.hardware.usb library. This version works only for v3.1+ devices (API12+).

The firmware, documentation, and additional information are available at www.microchip.com/android.
