Raspberry Pi Pico - Programmable IO (PIO)

The Raspberry Pi Pico uses an RP2040 microcontroller, which has a powerful Programmable Input/Output (PIO) system capable of providing many different types of interfaces, from pulse-width modulation light control to I2S digital audio to basic HDMI TV output. This week we'll explore the basics of the PIO system and how it provides this powerful capability.
