Original sketch text:
This is an example sketch for the Adafruit 2.2" SPI display.
This library works with the Adafruit 2.2" TFT Breakout w/SD card
----> http://www.adafruit.com/products/1480
Check out the links above for our tutorials and wiring diagrams
These displays use SPI to communicate, 4 or 5 pins are required to
interface (RST is optional)
