The Pixel Framebuf library makes drawing to a grid of NeoPixels or DotStars as easy as writing to a display. The library has all of the drawing functions of the original framebuf library, including the ability to draw lines, circles, rectangles, and text.
This library can be used on a wide variety of NeoPixel and DotStar LED layouts including with flexible and non-flexible matrices, NeoPixels strips laid out by hand, or FeatherWings. This library has been tested to work with both CircuitPython Microcontrollers and Blinka on the Raspberry Pi.
One of the huge advantages that using NeoPixel and DotStar LED matrices has over the standard RGB LED matrices is that they only use one or two GPIO pins. The Pixel Framebuf library gives you the simplicity and control to make use of these matrices to display data in a meaningful way in much the same way that you can on RGB matrices.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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.
