Display drivers for MAX7219, WS2812, APA102
Python 3 library interfacing LED matrix displays with the MAX7219 driver (using SPI) and WS2812 & APA102 NeoPixels (inc Pimoroni Unicorn pHat/Hat and Unicorn Hat HD) 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,
- pygame emulator,
- Python 2.7 and 3.5+ are both supported
Full documentation with installation instructions and examples can be found on https://luma-led-matrix.readthedocs.io.
A LED matrix can be acquired for a few pounds from outlets like Banggood. Likewise 7-segment displays are available from Ali-Express or Ebay.
Version 0.3.0 was released on 19 January 2017: this came with a rename of the github project from max7219 to luma.led_matrix to reflect the changing nature of the codebase.
There is no direct migration path, but the old docs and PyPi packages will remain available indefinitely, but that deprecated codebase will no longer recieve updates or fixes.
The consequence is that any existing code that uses the old max7219 package should probably be updated.
