I have been working with FS2phidget for two days now, really a great piece of software. I found most of the things I wanted to assign but I can't figure out how to assign the elevator trim up and down to a pair of switches.
So I assigned a keystroke for this but the "repeat" of the key doesnt work. Anyway, I think it must be possible to assign this without keystroke direct with an offset.
Perhaps someone can set me in the right direction :-)

Thanks

Is it a real Mason manufactured switch from a Boeing yoke or something else?

If you need a wiring diagram of the Mason switch I can post it here.

I am not too familiar with FS2Phidgets, however with that being said, is there not a way, that you can program the switch with an option that is selectable through FSUIPC?

Other then that, I would think there would be a way to program the function in FS2Phidgets.

Well it is a simple On/Off/On momentary toggle switch, so I would like to assign the trim up to one and themply trim down to the other. The wiring is not a problem, it is simply connected to a 0/16/16 board in 2 digital inputs.
So I need to figure out a way to make it work like this.

The following will work with either:
(a) 2 momentary switches (one for trim up, the other for trim down)
(b) 3 position toggle switch, preferably spring loaded to center off, although spring loading is not essential.

Either way, you need to wire the two switch wires to any 2 digital input ports on the phidget card.

Assign both of these ports to the ELEVATOR_TRIM_CONTROL FS variable and ensure to select FS var file FSVariables431 or later. Offset should read 0BC0 on the fs2phidget selection screen.

On the configuration screen press the "Continuously Step Value" radio button and set "Step Value" to 100. Set the other port to -100 (minus 100). This will cause the elevator control value to step continuously (either up or down, depending on the step value) while a digital input is held on. Play around with the step value to get your desired trim rate.

Regards,
Alan.

Thanks Alan,

I will do that, I knew it had to be possible.
