/***************************************************
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)
