LEDMatrix

---

A fork of https://github.com/marcmerlin/LEDMatrix, which is a fork of (cLEDMatrix by Aaron Liddiment) and build in some features from (Adafruit-NeoMatrix)

The goal here is to mutilate these functions so they are easier to use at global scope.

Once you have downloaded the Zip file, it should be extracted into your Arduino Libraries folder and the folder renamed to "LEDMatrix".

The LEDMatrix library builds a giant two-dimensional graphics array which can be used by FastLED. You can then easily draw shapes, text and animation without having to calculate every X/Y pixel position. Larger displays can be formed using tiles of LED strip / matrices - to build one big matrix. Similar to Adafruit-NeoMatrix (see picture below as example).
