00002     ILI9340_Driver  v1.1    01.06.14    Ian Weston
00003     
00004 Driver and integrated graphics library for displays that use the 
00005 ILI9340 controller in SPI mode. Such as the Adafruit 2.2" display.
00006 
00007 This code has been ported from several sources. The driver section
00008 was completely ported from the Adafruits Arduino source code, and
00009 the graphics functions were ported from the Adafruits GFX library
00010 and some elements were ported from code by Elmicros seeduio port.
00011 
00012 Future revisions will include more advanced graphics functions.
