/*************************************************** 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 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!
