Hi John,
I found out a long time ago you can’t mix commands for a GoFlight unit between those assigned via the GoFlight program or FSUIPC and Pollypot GIT if you want the LEDs to light up. It’s all or nothing.
I have programmed my hardware for the PMDG737 using their SDK and a post here on your forum describing how to do it. It’s worked perfectly well for several years. I have other aircraft also programmed the same way but are far less complex than the PMDG.
A couple of switches or buttons have more than one command assigned to them which requires manual editing of the FSUIPC6.ini. Very powerful and rewarding. 😄
Of course it all means nothing when the DLL isn’t there! 🤣
