Controlling Yoke Rocker Switches

Recommended Posts

Pete--I have currently several rocker switches that I use to control the PMDG 737/777 MCP.  For example, the Airspeed Increase/Decrease command in fsuipc is


The problem is repeated pushes never hit the right AS, e.g. 150 KIAS to 160 KIAS usually winds up ~165 KIAS.  I've experimented with the Action, the PollInterval and the ButtonRepeat parameters, but have not been successful.  Any ideas/assistance would be appreciated--Thanks,

Why are you using Keystrokes? The problem most likely is that the button press is resulting in a keystroke which is beng looked up to find the action assigned to that, all via Wndows messages which queue. Are the keystrokes, rather than the buttons, repeating? You can use the FSUIPC Key/Button logging to check.

The PMDG aircraft do have individual controls you can assign, via <custom control> assignment. You get the numbers for them from their SDK .h file, towards the end. I think they would be more reliable than keystrokes.
