As part of the R&D work on port! datatype in port-type branch, we have implemented a GPIO driver for Raspberry Pi boards, as a gpio:// scheme (no third-party library needed). This work helped define the low-level API for ports written in purely Red/System or a mix of Red and Red/System. The Raspberry Pi is a very popular board with millions of units sold, so this is a market where Red could be potentially helpful to developers.
