+/***************************************************
+ 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 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!

+/***************************************************
+ 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 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!
