This driver generates the high-frequency data protocol required to talk to a line of NeoPixel RGB LEDs (I used the following 8×8 NeoPixel grid from AdaFruit: https://www.adafruit.com/products/1487). The driver reads pixel data from a pixel buffer in shared memory.
One driver COG can update several lines of NeoPixels. Or separate driver COGS can be spun up to manage each NeoPixel line.
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.
