SomeRandomBloke 0:99ee879ef5a9 2 This is a library for the Adafruit 1.8" SPI display.
SomeRandomBloke 0:99ee879ef5a9 3 This library works with the Adafruit 1.8" TFT Breakout w/SD card
SomeRandomBloke 0:99ee879ef5a9 4 ----> http://www.adafruit.com/products/358
SomeRandomBloke 0:99ee879ef5a9 5 as well as Adafruit raw 1.8" TFT display
SomeRandomBloke 0:99ee879ef5a9 6 ----> http://www.adafruit.com/products/618
SomeRandomBloke 0:99ee879ef5a9 7
SomeRandomBloke 0:99ee879ef5a9 8 Check out the links above for our tutorials and wiring diagrams
SomeRandomBloke 0:99ee879ef5a9 9 These displays use SPI to communicate, 4 or 5 pins are required to
SomeRandomBloke 0:99ee879ef5a9 10 interface (RST is optional)
SomeRandomBloke 0:99ee879ef5a9 11 Adafruit invests time and resources providing this open source code,
