Adafruit_GFX-compatible library for NeoPixel matrices and grids. Controls single and tiled NeoPixel displays. This library requires FastLED and Adafruit_GFX libraries.
Please see https://learn.adafruit.com/adafruit-neopixel-uberguide/neomatrix-library for how to use this library.
Example code: https://github.com/marcmerlin/FastLED_NeoMatrix/blob/master/examples/MatrixGFXDemo/MatrixGFXDemo.ino
More complex example code: https://github.com/marcmerlin/NeoMatrix-FastLED-IR
This code was taken from Adafruit_NeoMatrix and adapted to work with the more powerful FastLED library. The reasons for using FastLED instead of Adafruit::Neopixel as a backend, include:
- FastLED supports more microcontrollers
- Better support for ESP32 than Adafruit::Neopixel
- Support for parallel output on some chips for faster refresh rate: https://github.com/FastLED/FastLED/wiki/Parallel-Output
- Support for interrupts to allow things like Infrared to work while updating strips
- Support for many more led/pixel hardware: https://github.com/FastLED/FastLED/wiki/Chipset-reference
