KAS 297B Altitude Selector Hardware Binding
-
Hi all,
Using Mobiflight we have successfully set the following variables to buttons on controller:
Altitude Select Knob Push/Pull (L:var_VsAdjustMode)
Inner Knob Increase (H:kas297b_100_INC)
Inner Knob Decrease (H:kas297b_100_DEC)Using the mouse, in VS mode, the mouse wheel moves the knob and adjusts VS. In Altitude mode it adjusts the altitude.
But using the controller binds, the knob only adjusts VS in either mode.
I am sure I must be missing something... been at it for hours haha please help!

Hm. The instrument should be reading directly from L:var_VsAdjustMode to determine what mode it's in whenever you send the knob events. Are you sure the knob is visually pulled in/out when you set L:var_VsAdjustMode with your hardware? Otherwise, you're welcome to send me screenshots or a video of the situation, and I might see something that we're both missing.

Hi, thanks for coming back so quick!
Yes when we press the button bound with L:var_VsAdjustMode, it moves in and out just fine, and the display changes.
For instance, in altitude mode the display says ft, but when we increase or decrease it jumps back to VS and changes that.
I hope that makes sense if not I can make a video no problem.
Cheers!

Oh, your description makes perfect sense! It's the behavior that doesn't! Haha.
You say it "jumps back" to VS. Do you mean the knob pulls back out when you try adjusting the altitude, or is it like when you adjust the vertical speed externally, and ft/min is only shown for a few seconds before returning to the altitude?
If the knob actually pulls back out, then I think it might be something with whatever script you've written in Mobiflight that's accidentally setting L:var_VsAdjustMode again. Just a hunch, since I've been known to make similar mistakes myself. Sorry if that's not it, but I try to give my users my best guess in each post so I don't keep them waiting!

haha

The second one!, it happens like this: "when you adjust the vertical speed externally, and ft/min is only shown for a few seconds before returning to the altitude?"
please see quick video below

Thanks for the video. You would be surprised what a difference that can make sometimes! What I'm noticing in this video is the suspicious rapid flickering of the up/down arrows as soon as you press the physical button. My guess is that you might have the hardware "double-bound", so that it's sending "K:AP_VS_VAR_INC", or is maybe bound in the simulator's default controls menu in addition to the desired command in Mobiflight.

aha! well spotted!
Increase and decrease VS was indeed set in the simulators controls from when my Dad was trying to get it working before I introduced him to Mobiflight and direct commands... !
Thanks again for your time, really appreciate it, he's happy now!
