Micropython Library for the HT16K33-based LED Matrices, ported from Adafruit's Adafruit_CircuitPython_HT16K33 library.
It supports Adafruit's 16x8 and 8x8 matrices, as well as 7-segment numeric and 14-segment alphanumeric displays.
The code for the matrix displays are here and should just work. However, I can not test these because I do not have any of these displays.
NOTE: At this time, only the 14-segment alphanumeric and 7-segment numeric displays have been tested. Others may work but have not been tested. Be warned!
