NEW GUIDE: MicroPython Hardware: Charlieplex LED Matrix @micropython

 

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.
