This is our GFX example for the Adafruit ILI9341 Breakout and Shield ----> http://www.adafruit.com/products/1651 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!
