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