/*!
* @file Adafruit_ILI9341.h
*
* This is the documentation for Adafruit's ILI9341 driver for the
* Arduino platform.
*
* This library works with the Adafruit 2.8" Touch Shield V2 (SPI)
* http://www.adafruit.com/products/1651
* Adafruit 2.4" TFT LCD with Touchscreen Breakout w/MicroSD Socket - ILI9341
* https://www.adafruit.com/product/2478
* 2.8" TFT LCD with Touchscreen Breakout Board w/MicroSD Socket - ILI9341
* https://www.adafruit.com/product/1770
* 2.2" 18-bit color TFT LCD display with microSD card breakout - ILI9340
* https://www.adafruit.com/product/1770
* TFT FeatherWing - 2.4" 320x240 Touchscreen For All Feathers
* https://www.adafruit.com/product/3315
*
* 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!
*
*
* This library depends on <a href="https://github.com/adafruit/Adafruit_GFX">
* Adafruit_GFX</a> being present on your system. Please make sure you have
* installed the latest version before using this library.
