Intro to Raspberry Pi Pico and RP2040 - MicroPython Part 3: PIO | DigiKey

In the previous videos, we showed you how to get started using MicroPython on the Raspberry Pi Pico. In this tutorial, we’ll examine the new PIO peripheral inside the RP2040. PIO stands for “Programmable Input/Output,” and it’s a unique peripheral added to the Raspberry Pi RP2040 microcontroller. It is like a set of tiny, limited processors that allow us to construct complex communication protocols, such as CAN, USB, Ethernet, etc. by bitbanging them independently of the main CPU.
