Ian Weston / Mbed 2 deprecated ILI9340_Driver

Demo project to demonstrate that ILI9340 display driver and graphics library. very simple but a good starting point for any project using such a display. Please use this to thoroughly enjoy yourself and make your projects cool!

Dependencies:   ILI9340_Driver_Lib mbed

About the Driver:

This driver will drive any display that uses an ILI9340 display controller in SPI mode - such as the adafruits 2.2" 240 x 320 display found here: http://www.adafruit.com/products/1480

All this code has been ported from other peoples hard work - Thanks to All !
