Adafruit_Protomatter is a C library (with Arduino and CircuitPython front-ends) for driving RGB LED matrices. This guide is mostly to assist with porting Adafruit_Protomatter to new hardware. Like a nebula birthing new stars, Protomatter is an early stop for new microcontrollers on their way to full CircuitPython support…it’s sometimes easier to start off in the Arduino realm.
We already have one such library — RGBmatrixPanel for Arduino — it’s older code that works fine for AVR chips (and a couple others) but saddled with some limitations. Protomatter isn’t exceptionally clever or 1337, it’s just aiming to get the job done with minimal fuss on a range of modern hardware. Support is in place for SAMD21 and ’51, nRF52840, ESP32 and STM32F405, while Teensy 4 is in progress…
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.
