These things are pretty much unrelated to each other. GPIO is a General Purpose IO - meaning these are not connected to a specialized interface. PIO is Programmable IO, meaning that it can be connected to any interface present on the chip. The latter present mostly on FPGAs, while GPIO is on microcontrollers and such.

WebTo be useful in gaining a general understanding of GPIO usage and real world interfacing. Avoid cables and breadboards and try to fit a standardised form factor. In this case a plugable "faceplate" for the exiting gpio port. The board should avoid constraining any existing ports and access. Ideally, provide onboard visual feedback to aid learning.

WebThe code implementing a gpio_chip should support multiple instances of the controller, preferably using the driver model.
