This is a library for the Adafruit 1.8" SPI display.
This library works with the Adafruit 1.8" TFT Breakout w/SD card
----> http://www.adafruit.com/products/358
as well as Adafruit raw 1.8" TFT displayun
----> http://www.adafruit.com/products/618
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)
Adafruit invests time and resources providing this open source code,

/*The Crystalfontz CFAF128128B-0145T color 128x128-pixel TFT LCD supports display updates up to 20 frames
per second (FPS) while only requiring a few lines to control the TFT LCD module through the SPI interface. This
module has a color depth of 262K colors and a contrast ratio of 350. The reference designator for the color LCD
is LCD1.
