feat(firmware): add ability to set source for backlight / brightness and volume controls

[philmoz]

Set a Pot, Slider or Switch to control brightness without using a special / global function.

If a Backlight special / global is defined it will take precedence over this new radio setting.

TODO:

• limit selection to Pots, Sliders or Switches Companion radio settings editor.

[philmoz]

@elecpower When you have some time could you look at the companion side please.
I have implemented the YAML read/write and added the control to the radio settings edit page.

It needs to be updated to limit the backlight control to only select Pots, Sliders or Switches,

I think this does go against the whole logic, where things are done throuht SF. Now it is a settings, a GF, a SF, for people to understand what happens , it becomes a nightware.

What happens if you usually don't need to use the pot, but this new model needs it for a gyro gain for example ?

Looks like #2256 won't be needed anymore then, and the issues it addressed can be moved to here...

No, it gives a mechanism to it without using GF or SF. If you need something more advanced, you use that instead.

Same could be said for Brightness GF... i.e. you wouldn't configure it globally, or you use it for both.

The commit above fixes the source list. The dynamic update part is a wip

This PR #6684 is interesting and could be helpful to band-aid the primary problems in SF backlight I observe since introduced in EdgeTX ~v2.6.x. But this PR still does not provide a complete solution to allow setting both an alternate backlight brightness and control... Please consider/investigate issue #5851 as well.

Thank you & Happy to test :-)

As I poke with this a bit I find myself agreed with @3djc. We are not talking about a menu navigation button, this is normal user controls and they should be left for user to configure in SF / GF.

Thanks for that. A couple of things:

• Tilt X & Tilt Y should not be selectable
• Negative / inverted values should be selectable.

• Tilt X & Tilt Y should not be selectable
• Negative / inverted values should be selectable.

Noted and will incorporate

[elecpower]

Custom function switches not listed correctly and will be addressed as part of the larger issue

[elecpower]

TODO: add flex switches to list
Update: done

[elecpower]

@philmoz back to you for testing

@philmoz back to you for testing

Looks good - thank you.

For consistency then, shouldn't the same apply to audio and variometer volumes ?

One step at a time.

[philmoz]

Added audio volume control as well.

Looks like I need to rename the source item model to a generic name. I'm open to suggestions.
