DMA NeoPixels for ARM Cortex-M0 Boards

If you’re using a recent “M0” development board such as the Adafruit Feather M0, Circuit Playground Express or

Arduino Zero, an alternate NeoPixel library (https://adafru.it/xBb) exploits these devices’

direct memory access

(DMA)

feature to operate more smoothly. Advanced Arduino sketches can then use interrupts with impunity, and code that

depends on the millis() or micros() functions will not lose time.

There’s a corresponding DMA version of the NeoMatrix library (https://adafru.it/xAQ) as well.

Plus a super potent 8-way concurrent NeoPixel DMA library (https://adafru.it/Blw). We offer a

companion FeatherWing (https://adafru.it/Et6) and breakout board (https://adafru.it/CJd) to make connections and

level-shifting easier!

Third-Party Libraries

In addition to the previously-mentioned FastLED library, NeoPixel-compatible libraries have been developed for
