NEW GUIDE: NeoPIO drive lots of LEDS with #CircuitPython on @Raspberry_PI Pico #AdafruitLearningSystem @Adafruit @JeffEpler
There’s a new guide in the Adafruit Learning System from Jeff Epler:
The new RP2040 microcontroller from Raspberry Pi Foundation has a powerful feature: the PIO module, a sort of accelerated I/O processor.
One advantage of driving your NeoPixel LEDs this way is that less time is spent actually sending the pixel data to the LEDs—It is about 7.5x faster to show() your NeoPixels with the parallel method. Depending on your project, having parallel strips as opposed to chained strips can also make for better wiring.
Check out the guide now and learn more about the Programmable Input/Output (PIO) controller of the Raspberry Pi Pico. What project will the Pico’s PIO module will help you make? Let us know in the comments.
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.
