/*!
 * @file Adafruit_HX8357.h
 *
 * This is the documentation for Adafruit's ILI9341 driver for the Arduino
 * platform.
 *
 * This library works with the Adafruit 3.5" TFT 320x480 + Touchscreen Breakout
 *    http://www.adafruit.com/products/2050
 *
 * Adafruit TFT FeatherWing - 3.5" 480x320 Touchscreen for Feathers
 *    https://www.adafruit.com/product/3651
 *
 * These displays use SPI to communicate. This requires 4 pins (MOSI,
 * SCK, select, data/command) and optionally a reset pin. Hardware SPI
 * or 'bitbang' software SPI are both supported.
 *
 * 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.
