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.
