/***************************************************************
    ILI9340_Driver  v1.1    01.06.14    Ian Weston
    
Driver and integrated graphics library for displays that use the 
ILI9340 controller in SPI mode. Such as the Adafruit 2.2" display.

This code has been ported 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.
