If you’ve used NeoPixels extensively you’ve likely seen some issues in how they interact with other code. The Arduino millis() and micros() functions lose accuracy, the Servo library may stutter, or refreshing a very long NeoPixel strip can slow a program down.
A solution is presented for development boards based around the ARM Cortex-M0 microcontroller, such as the Adafruit Feather M0, Circuit Playground Express or Arduino Zero, using these devices’ DMA-driven SPI capability.
