V1.1 of the ILI9340 driver for SPI with integrated graphics functions.

Dependents:   ILI9340_Driver SDCard_Aitendo_2p2TFT TFT22ok_test_ILI9340_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 !

/***************************************************************
    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.
