Steppers and Potentiometers [closed]

Question

I like the new configurator layout...you guys are hard at work. Two things I noticed, for trim input (aileron, rudder, etc), the option for using a potentiometer is gone? I thought this was an option before. Using an encoder, you would have to set the trims back to neutral before shutdown so that they would be in sync when xPlane is started again, correct? I just bought some 10 turn pots to use for my trim functions.

Also, I notice on the gauge outputs, (king air type cabin pressure for example), the stepper option is gone? Are you recommending new builders use servos only? I am planning to build a few instruments and was leaning towards steppers instead of servos.

Thanks for all of you tireless efforts!

Answer 1

Leslie,

I have added an analog input option, take a look,
But please read the NOTE on that page.

No, of course you don't need to "set the trims back to neutral" with encoder, why? An encoder is an relative increment device, not absolute.

2. I will add a stepper option too, just need time, it's just working process...

Thanks Vlad...I am building geared trim indicator like in the real airplane, if it is to the left when I shut down, on startup xPlane resets trim to neutral, my indicator would not be correct. I figured (maybe not), that a potentiometer would be read on startup and set the trim to whatever the trim is as indicated.

As you see Note 2: If you are using analog input, you don't need to create a trim position gauge, as you can simply make it mechanically coupled (by gearbox) with the trim wheel.

If you use encoder, you need to create the trin position gauge on the servo (or LED bar indicator).

It doesn't matter where the servo gauge stopped on the XP shutdown,
when you start X-Plane (aircraft) the gauge will return to the position that currently set in X-Plane model (usually zero or TO).

NOTE. Although there are two options available for trim control, an encoder and an analog input (potentiometer), it is highly recommended to use an encoder as it is more accurate and not affected by electrical noise and interference.

As example see the video from my Baron 58 pedestal - it's simple - the encoder used for wheel
and the servo used for the mechanical indicator:

The video is below of this page.

And here is diagram how it's made:
