This tool enables dataexchange between the Flight Simulator program and your own sourcecode or other FS client applications. I have been experimenting with the FSUIPC.dll file that is available (Free till FS2002) on the internet as SDK (Software Development Kit) and provided with a simple example to help you up, concerning how to read data from flight simulator using your own C++ program. Sufficient documentation is provided with this tool. I got excited when I got the first results, just reading and wirting data to Flight simulator. My next step was to see if I was able to forward the data, that was read from Flight Simulator with my C++ program, to my microcontroller. It succeeded, and I tried the opposite too, press a button on the microcontroller and write the buttonaction to a flight simulator object. From this point on, I got quit sure that building a full scale Flight simulator cockpit might come true.

FSUIPC is also used by the FSBus software to interact with Flight Simulator.
