Trim-Buttons on Jumper T12

Post by wilopaan »

Hi all,

a user in another forum pointed out to me that it should be possible to use the trim knobs as a general switch / button.

I tried to use them (e.g. TR1) for a mixer input, but it looks like I made something wrong.

Is it really possible? How? Any hints?

Thanks.

Trim need then first to be disabled in flight mode to disable the beeps and everything, then create an input with it I guess, or control a mix based on MAX

To clarify, TR1 is trainer input 1, nothing to do with trim.
If you want to use the trims as buttons they are in the list of switches, not of sources. tEd for trim Elevator down etc.

Thank you!

If the trims are then disabled, one can achieve a trim-effect say with a scipt returning some fixed value or just using the side-wheels.

If I try to use getValue("tEd") I always read 0 (zero).

I can define an edge-logical switch for tEd or an or-logical switch with a constant logical-switch and then read this logical-switch.

Is there a way to read the "tEd" directly by a lua script?

thx.

I have to define an inputs with two lines:
- one is active with tEd outputting MAX
- one is active with !tEd outputting -MAX (or 0)

Then pushing the trim gives MAX, releasing gives -Max.
This can be polled in a Widget to detect a chance and generating a pseudo event.

Is there a simple method to get this result? Because I need 3 actions (prev, next, select) I need three inputs.
