Updated Guide: New PIO functionality in #CircuitPython with RP2040 @adafruit

Jeff Epler recently added some new PIO functionality to the core of CircuitPython: the background_write function. This lets Python code continue running while data is being sent to a PIO peripheral. The guide “An Introduction to RP2040 PIO with CircuitPython” has now been updated with several new pages to show some things this enables:

Check out the new pages, or if you are new to PIO with CircuitPython, start at the beginning.


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.
