Microcontroller chips, like our own RP2040 on Raspberry Pi Pico, offer hardware support for protocols such as SPI and I2C. This allows them to send and receive data to and from supported peripherals.

But what happens when you want to use unsupported tech, or multiple SPI devices? That’s where Programmable I/O, or PIO, comes in. PIO was developed just for RP2040, and is unique to the chip.
