[Sticky] FFairLink for MSFS (communications with arduino/teensy etc)

You probably remember Link2FS, the tool many of us used to get started in cockpit building. I’ve decided to create something more advanced for MSFS: FFairLink.

You can list, read, and write offsets and Lvars, perform any mathematical operations you need with them, and send them via a serial port to any Arduino, Teensy, ESP32, or any hardware of your choice. From there, you can process these variables and send messages back to FFairLink, which then translates them into commands or writes to offsets and Lvars.

Using a handshake system, FFairLink automatically detects the port Windows has assigned to that specific device for the day (finally, no more searching to see which port each thing has been assigned to!).

You can add over 200 Arduinos per aircraft profile. For each device, you can register as many variables as you like, assign them a code, and have them sent to the Arduino.

My Piper Comanche cockpit is already fully operational using this system:

I will be publishing the code and Arduino examples for sending and receiving messages with FFairLink.

Thanks, fsuipc!
