Overview

This project focuses on demoing an extended screen display using multiple uLCD screens. A library was written for Multiscreen display called uLCD Multiscreen and is available at http://developer.mbed.org/users/Mkuchnik3/code/uLCD_Multiscreen/. This library allows us to connect up to 3 screens on to the mbed as per rx/tx pin limitations.

For the purpose of demo, we implement a simple Sparkfun Thumb Joystick program that allow us to move the ball across the screen.
