+/******************************************************************
+ A library for controling a set of 8x8 LEDs with a MAX7219 or
+ MAX7221 displays.
+
+ This is a plugin for Adafruit's core graphics library, providing
+ basic graphics primitives (points, lines, circles, etc.).
+ You need to download and install Adafruit_GFX to use this library.
+
+ Adafruit invests time and resources providing this open
+ source code, please support Adafruit and open-source hardware
+ by purchasing products from Adafruit!
