Software defined USB port (Raspberry Pi pico RP2040)

A bit off topic but does anyone know if there's anything like a standalone PIO?

They seem genuinely fun to use even without the pico attached.

Isn't a standalone PIO literally just a microcontroller?

You may have fun playing around with a Parallax Propeller MCU. Rather than have a bunch of peripherals, the Propeller has 8 CPU cores. The idea is that you implement whatever peripherals you want by dedicating cores to the purpose and bit-banging it. It's a similar idea to a PIO, but rather than having a main core and a bunch of tiny cores, you just have a bunch of equally capable cores.

Sort-of related things:

- GreenPAK

- Programmable Array Logic (PAL)
