Introduction

Python library interfacing LED matrix displays with the MAX7219 driver (using SPI) and WS2812 & APA102 NeoPixels on the Raspberry Pi and other linux-based single board computers - it provides a Pillow-compatible drawing canvas, and other functionality to support:

  • multiple cascaded devices
  • LED matrix, seven-segment and NeoPixel variants
  • scrolling/panning capability,
  • terminal-style printing,
  • state management,
  • dithering to monochrome,
  • Python 2.7 and 3.4+ are both supported
