This is an adaptation of lavallc's Maple port of the NeoPixel library for STM32Duino. It is not compatible with other boards at this time. We added "-ANDnXOR" to the file names so there won't be a conflict in your build environment. Hopefully we'll find time to pull in the latest Adafruit changes.
Adafruit NeoPixel library
Arduino library for controlling single-wire-based LED pixels and strip such as the Adafruit 60 LED/meter Digital LED strip, the Adafruit FLORA RGB Smart Pixel, the Adafruit Breadboard-friendly RGB Smart Pixel, the Adafruit NeoPixel Stick, and the Adafruit NeoPixel Shield.
After downloading, rename folder to 'Adafruit_NeoPixel' and install in Arduino Libraries folder. Restart Arduino IDE, then open File->Sketchbook->Library->Adafruit_NeoPixel->strandtest sketch.
