NEW GUIDE: An Introduction to RP2040 PIO with #CircuitPython #AdafruitLearningSystem @Adafruit @jeffepler
The RP2040 has a powerful I/O co-processor called PIO. Learn about how to use PIO together with CircuitPython in this new guide by Jeff Epler:
In this guide, you’ll learn how to write and use PIO programs from CircuitPython. The official datasheet (chapter 3), the book “Get Started with MicroPython on Raspberry Pi Pico” and pico-examples (pio folder) are helpful resources too, but CircuitPython sometimes deviates from the way that PIO is used in other environments like C or MicroPython.
The guide currently has 4 examples, from turning an LED on and off, to controlling a NeoPixel, and work with the Raspberry Pi Pico and the Feather RP2040! Check it out on the Adafruit Learn System.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
