/**************************************************************************
This is a library for several Adafruit displays based on ST77* drivers.
Works with the Adafruit 1.8" TFT Breakout w/SD card
----> http://www.adafruit.com/products/358
The 1.8" TFT shield
----> https://www.adafruit.com/product/802
The 1.44" TFT breakout
----> https://www.adafruit.com/product/2088
as well as Adafruit raw 1.8" TFT display
----> 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,
please support Adafruit and open-source hardware by purchasing
products from Adafruit!
