I have three (soon to be four) Teensy 3.5 boards configured as XPlane FlightSim devices, and I need someone to point me in the right direction to talk between the boards. They all show up in Arduino as the same Teensy port number which I've already posted about, so I'm at a loss as to how to go about making one board tell something to another board.
If there is a way to create custom DataRefs in the XPlane interface, that would make it easy, but I haven't found that anywhere.
Any ideas out there?
