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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
