15 years ago I had to create a display system written in Unity for cinemas, there was a capacitive PID controller I had to interface with - at the time it was impossible in Unity - it was a generic PID which just returned a stream of data, meaning there was no discrete driver for the device. I ended up writing a program in another language - can't recall which - which interfaced with the controller and linked to unity c# through some obscure windows IPC (I think it was Pipes?). Fun days in early Unity... nostalgia ;-)
