This time, I’ve gone way beyond just the LPD8806 and Raspberry Pi. BiblioPixel takes the pain out of controlling your LEDs and programming your animations. It provides a “code once, run on anything” foundation with a robust driver model, allowing control of nearly any display type, strip or matrix. For matrices built from LED strips, it automatically handles the conversion of (x,y) coordinates to strip indices. It is also orders of magnitude faster than the old library, having been written with high frame rates in mind.
On devices with SPI output, such as the Raspberry Pi or BeagleBone Black, strips like the LPD8806 or WS2801 can be controlled directly. Animations can be sent over a network connection to a remote device, and then output to a set of LEDs. There’s even a built-in software visualizer for displaying animations directly in a window; great for testing.
What makes this new library special is the ease of writing new animations and adding device support. Details on both are available in the GitHub wiki.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
