Python 3 library interfacing LED matrix displays with the MAX7219 driver (using
SPI), WS2812 (NeoPixels, inc Pimoroni Unicorn pHat/Hat and Unicorn Hat HD) and
APA102 (DotStar) on the Raspberry Pi and other Linux-based single board computers
- it provides a `Pillow <https://pillow.readthedocs.io/>`_-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,
* pygame emulator,
* Python 3.7 and newer are supported
