  • NeoPixelBus

    An Arduino NeoPixel support library supporting a large variety of individually addressable LEDs. Please refer to the Wiki for more details. Please use the GitHub Discussions to ask questions as the GitHub Issues feature is used for bug tracking.

    • FastLED doesn't natively support RGBW addressable strips as of version 3.5.0 (October 2022). The alternate library NeoPixelBus does support RGBW strips, but handles animation in a completely different way than FastLED does.This snippet is an example of a way to shuttle data from FastLED RGB to NeoPixelBus RGBW, for folks (like me!) who prefer creating animations with FastLED.The additional library NPBColorLib is needed because NeoPixelBus doesn't (currently) use the white channel when converting RGB to RGBW -- see https://github.com/Makuna/NeoPixelBus/issues/323Tested with:FastLED, version 3.5.0 from https://github.com/FastLED/FastLEDNeoPixelBus, version 2.7.0 from https://github.com/Makuna/NeoPixelBusNPBColorLib, updated 2020-05-29 from https://github.com/jackjansen/NPBColorLib

  • FastLED

    The FastLED library for colored LED animation on Arduino. Please direct questions/requests for help to the FastLED Reddit community: http://fastled.io/r We'd like to use github "issues" just for tracking library bugs / enhancements.
