From the Forums: ESP8266 + MicroPython + IS31FL3731 Driver for FeatherWings!

Thanks to forums user deshipu for writing in with these various pieces of source code that utilize Micropython on the ESP8266, for various FeatherWings.

Available are servo and motor FeatherWing source, LED Matrix, 7-Segment and 14-Segment FeatherWing source, ADC, and my favorite, source for CharliePlex LED matrixes like this one.

About the CharlieWings, deshipu writes,

Looking at the datasheet, I noticed that this chip is capable of quite more than the Adafruit libraries allow, so I went ahead and included support for additional features:

  • Blinking pixels
  • Switching between frames
  • Fading between frames
  • Automatic animation
  • Music-driven animation

    • Great!
