P8X32A/Propeller driver object for Neopixel addressable LED arrays

smartled-spin

---

This is a P8X32A/Propeller driver object for various model smart/addressable LED arrays (e.g., NeoPixels)

IMPORTANT: This software is meant to be used with the spin-standard-library (P8X32A) or p2-spin-standard-library (P2X8C4M64P). Please install the applicable library first before attempting to use this code, otherwise you will be missing several files required to build the project.

Salient Features

• Supports WS2811, WS2812, WS2812B, WS2813, SK6812 (RGB and RGBW), and TM1803-based LED arrays
