DrCoyle 0:1e675eea5267 2 This is a library for the Adafruit 1.8" SPI display.
DrCoyle 0:1e675eea5267 3 This library works with the Adafruit 1.8" TFT Breakout w/SD card
DrCoyle 0:1e675eea5267 4 ----> http://www.adafruit.com/products/358
DrCoyle 0:1e675eea5267 5 as well as Adafruit raw 1.8" TFT display
DrCoyle 0:1e675eea5267 6 ----> http://www.adafruit.com/products/618

DrCoyle 0:1e675eea5267 8 Check out the links above for our tutorials and wiring diagrams
DrCoyle 0:1e675eea5267 9 These displays use SPI to communicate, 4 or 5 pins are required to
DrCoyle 0:1e675eea5267 10 interface (RST is optional)
DrCoyle 0:1e675eea5267 11 Adafruit invests time and resources providing this open source code,
DrCoyle 0:1e675eea5267 12 please support Adafruit and open-source hardware by purchasing
