This is test software for my fully 3D printed design for a Dual Concentric Rotary Encoder with Push Button. It's useful for making the knobs for flight-sim radio panels, where there is an outer knob to set the smaller digits, and an inner knob to set the larger digits.

This test program connects the device to X-Plane via the ExtPlane Plugin, and demonstrates controlling the X-Plane G1000's COM radios.
You will need to install my X-Plane ExtPlane Client library.
