Thanks to Adafruit Forums usererichs for posting up all the tutorials he wrote up on how to drive WS2812/NeoPixels with a Freescale FRDM board!
Greetings,
I have created a multi-part tutorial about how to drive WS2812/NeoPixels with a Freescale FRDM board (ARM Cortex-M4F) with Eclipse and GNU tools:Tutorials: Adafruit WS2812B NeoPixels with the Freescale FRDM-K64F Board:
Part 1: Hardware http://mcuoneclipse.com/2015/08/01/tutorial-adafruit-ws2812b-neopixels-with-the-freescale-frdm-k64f-board-part-1-hardware/
Part 2: Software Tools: http://mcuoneclipse.com/2015/08/01/tutorial-adafruit-ws2812b-neopixels-with-the-freescale-frdm-k64f-board-part-2-software-tools/
Part 3: Concepts: http://mcuoneclipse.com/2015/08/03/tutorial-adafruit-ws2812b-neopixels-with-the-freescale-frdm-k64f-board-part-3-concepts/
Part 4: Timer: http://mcuoneclipse.com/2015/08/03/tutorial-adafruit-ws2812b-neopixels-with-the-freescale-frdm-k64f-board-part-4-timer/

I hope this is useful for everyone who wants to get down to the wires and bits using these amazing LEDs!
Happy NeoPixeling 🙂
