NeoMatrix Library

The Adafruit_NeoMatrix library builds upon Adafruit_NeoPixel to create two-dimensional graphic

displays using NeoPixels. You can then easily draw shapes, text and animation without having to

calculate every X/Y pixel position. Small NeoPixel matrices are available in the shop. Larger displays

can be formed using sections of NeoPixel strip, as shown in the photo above.

In addition to the Adafruit_NeoPixel library (which was already downloaded and installed in a prior

step), NeoMatrix requires two additional libraries:

1. Adafruit_NeoMatrix (http://adafru.it/cDt)

2. Adafruit_GFX (http://adafru.it/cBB)

If you’ve previously used any Adafruit LCD or OLED displays, you might already have the latter

library installed.

Installation for both is similar to Adafruit_NeoPixel before: unzip, make sure the folder name

matches the .cpp and .h files within, then move to your Arduino libraries folder and restart the IDE.

Arduino sketches need to include all three headers just to use this library:

#include <Adafruit_GFX.h>

#include <Adafruit_NeoMatrix.h>

#include <Adafruit_NeoPixel.h>

#ifndef PSTR

#define PSTR // Make Arduino Due happy
