Hi Peter,
I bought an old DIY joystick (Boeing 737) whose speedbrake and flaps are built from microswitches and not potentiometers. Everything is connected to a Bodnard bu0386x. For the flaps, a micro-switch gives the direction (up or down) and another on the lever goes from on/off when you pull on the lever to change notches. I am using FSUIPC's compound buttons function to pass the flap increment or flap decrement commands. If I choose an FSX plane, I can see on the 3D view the needle of the gauge progressing (flap1,2,5, etc) but if I retract the flaps from one notch, the needle returns directly to flap1. I spent a lot of time without finding the solution. Can you help me.
