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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
