// Adafruit_ImageReader test for Adafruit ST7735 TFT Breakout for Arduino.
// Demonstrates loading images to the screen, to RAM, and how to query
// image file dimensions.

// (not 'bitbang') and must be wired to specific pins (e.g. for Arduino Uno,
// MOSI = pin 11, MISO = 12, SCK = 13). Other pins are configurable below.
