Please tag your post with either msfs-2020 or msfs-2024 if you would like to discuss a specific sim, as well as which platform you are on.
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.
It allows you to list, read, and write offsets and Lvars, perform any custom mathematical operations, and send them via a serial port to any Arduino, Teensy, ESP32, or any hardware of your choice. You can process these variables and send messages back to FFairLink, which then translates them into commands or writes to offsets and Lvars.
With its integrated handshake system, FFairLink automatically detects which port Windows has assigned to each device, saving you from manually configuring serial ports every time.
You can add over 200 Arduinos per aircraft profile. For each device, you can register as many variables as you like, assign them a unique code, and have them sent directly to the hardware.
My Piper Comanche cockpit is already fully operational using this system.
I will be publishing Arduino code examples for sending and receiving messages with FFairLink soon.
Total flexibility in cockpit building. If you can imagine it, you can build it.
