Change PFD , ND, ECAM and Panels brightness on a A32NX

[Sergiohst]

Hi!

I'm trying to control brightness with a physical potentiometer, but did not found the way...

There is a thing called project magenta that uses fsuipc and in their docs about fsuipc  (Project Magenta FSUIPC Offsets - Project Magenta)  found that offset 55F0 can control some of these:

I wrote some code to test it :

                                   byte[] bytes = { 100, 100, 100, 100, 100, 100,0,0 };
                                   new Offset<Double>(0x55F0).SetValue(BitConverter.ToDouble(bytes, 0));
but it doesn't work...

also found that :

                                  FSUIPCConnection.SendControlToFS(FsControl.PANEL_LIGHTS_SET, 10)

that changes the AP PANEL light, this is working.

 

any ideas??

 

Thanks!!

I can't really help with Project Magenta - please use their support as a first port of call for this.

Also, to control the A32NX, if using the FBW version, you should  also use the FBW support/discord channel.

However, you could also try activating logging (for Events and maybe also Axis Controls) and change the lights in the sim (via the UI) to see what events, if any, are logged, or what lvar values change, and then try assigning to those.
There are various Light Potentiometer controls/events available in MSFS that you can also try, e.g.:

However, at the moment only the Light Potentiometer Set control is currently flagged (in FSUIPC7) as an axis control, so the others cannot currently be used to assign to an axis. You can try the others by setting them to a key or button press, with an appropriate parameter, and I can update to allow them to be assigned to an axis if needed - I'll do this anyway as they are axis controls.

Hi !

No events are rised and I've tested to set all LIGHT_POTENTIOMETERS , some does things with some plane lights but not the instruments brightness.

I will ask for help in FBW Discord, will post results here if any 

 

Thanks John!!

[John Dowson]

Ok. You can also try listing the available lvars to see if any of them stand out (from Add-ons->WASM->List Lvars menu entry).

[Sergiohst]

Yes, I've checked all Lvars and offsets and there is no way.

In FBW support chat someone answered with:

"    I've asked a similar question twice already and never got an answer. So I assume it means "not possible".  "

maybe in a future release.... will post here if there are news.

 

Thanks!

Ok - thanks for the update.
