00001 /***************************************************
00002   This is an Arduino Library for the Adafruit 2.2" SPI display.
00003   This library works with the Adafruit 2.2" TFT Breakout w/SD card
00004   ----> http://www.adafruit.com/products/1480
00005 
00006   Check out the links above for our tutorials and wiring diagrams
00007   These displays use SPI to communicate, 4 or 5 pins are required to
00008   interface (RST is optional)
00009   Adafruit invests time and resources providing this open source code,
