/***************************************************
  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
The 1.14" TFT breakout
----> https://www.adafruit.com/product/4383
The 1.3" TFT breakout
  ----> https://www.adafruit.com/product/4313
The 1.54" TFT breakout
  ----> https://www.adafruit.com/product/3787
The 2.0" TFT breakout
  ----> https://www.adafruit.com/product/4311
as well as Adafruit raw 1.8" TFT display
  ----> http://www.adafruit.com/products/618

This also works with many of the products with integrated displays

The HalloWing M0 Express
  ----> http://www.adafruit.com/products/3900
The PyBadge
  ----> http://www.adafruit.com/products/4200
The PyGamer
  ----> http://www.adafruit.com/products/4242
The HalloWing M4 Express
  ----> http://www.adafruit.com/products/4300
    
  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!
