skydarc 2:2946f9eefcae 2 This is a library for the Adafruit 1.8" SPI display.
skydarc 2:2946f9eefcae 3 This library works with the Adafruit 1.8" TFT Breakout w/SD card
skydarc 2:2946f9eefcae 4 ----> http://www.adafruit.com/products/358
skydarc 2:2946f9eefcae 5 as well as Adafruit raw 1.8" TFT display
skydarc 2:2946f9eefcae 6 ----> http://www.adafruit.com/products/618
skydarc 2:2946f9eefcae 7
skydarc 2:2946f9eefcae 8 Check out the links above for our tutorials and wiring diagrams
skydarc 2:2946f9eefcae 9 These displays use SPI to communicate, 4 or 5 pins are required to
skydarc 2:2946f9eefcae 10 interface (RST is optional)
skydarc 2:2946f9eefcae 11 Adafruit invests time and resources providing this open source code,
skydarc 2:2946f9eefcae 12 please support Adafruit and open-source hardware by purchasing
skydarc 2:2946f9eefcae 13 products from Adafruit!
