MicroPython Hardware: Charlieplex LED Matrix is a new guide in the learning system:
Charlieplex displays use a unique wiring structure so many LEDs can be controlled with just a few shared wires. There are even specialized driver chips like the IS31FL3731 which can control a large number of Charlieplexed LEDs using pulse-width modulation to dim and brighten them at different intensity levels. Adafruit’s Charlieplex FeatherWing and breakout use this driver chip to make a large matrix of tiny LEDs that are super easy to control. Using a MicroPython IS31FL3731 module you can even control Charlieplex matrices from MicroPython code! This guide explores how to use the Charlieplex FeatherWing and breakout with MicroPython.
