/***************************************************************
    ILI9340_Driver  v1.1    26.05.14    Ian Weston
    
Demo project to demonstrate the ILI9340 display driver and graphics
library in action. very simple, good base for any project.    

About the Library:

Driver and integrated graphics library for displays that use the 
ILI9340 controller in SPI mode.

The code was prted from several sources, the driver section
was completely ported from the Adafruits Arduino source code, and
the graphics functions were ported from the Adafruits GFX library
and some elements were ported from code by Elmicros seeduio port.

Future revisions will include more advanced graphics functions.

Rough and ready Demo code to for showing the driver and some 
functions in action.
