New Library and Updated Guide: DMA-driven NeoPXL8 for M0 boards
Last month we solved the riddle of controlling a NeoPixel strip using SPI DMA (direct memory access) on SAMD21-based boards like the Feather M0 or Arduino Zero, freeing up the processor for other, more interesting things.
Sometimes even a DMA-driven strand of NeoPixels isn’t enough. Sometimes you need a firehose of color!
NeoPXL8 (pronounced “NeoPixelate”) is a more intense approach to driving NeoPixels on Cortex-M0+ microcontrollers, with eight separate strands all running concurrently. It shares the same benefits as NeoPixel_ZeroDMA — minimal CPU use, nondestructive brightness setting, plays well with timekeeping functions and servos
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.
