Transponder code display

[faint aspen]

@finite valley is the specialist here for the Fenix. But I think it’ll be better to check for bus voltage than battery switch. If you use battery on variable, your transponder will be on even if batteries are empty. What I would do is find on what bus power the transponder is powered. Have an output to check voltage on that bus and use this to power on/off all the cockpit panels and display on that bus.

The "brightness reference" in the 7-segment display configuration can also be zero, which turns off the display.

If it is MSFS, many planes use the generic "CIRCUIT GENERAL PANEL ON" variable that does the "do we have battery and required power buses powered, either by apu, ground power or engine generator?" logic for you.

But this varies accross add-on planes since people often build their own logic because whatever. And since a lot of the systems logic on Fenix is running in the prosim side and not on msfs, I am not sure what variables they use to map the prosim panel backlight and digits power to the MSFS side, but it got to be something.

Also you can always try to construct your own logic by making output variables for all the battery and bus states to check, and then multiplying among them to create your own MF variable that you can use as part of your digits brightness reference.

Yes I use 0 to turn off and 5 value for brightness.

That's what I try since few days ago ☺️
But all states of the Fenix are not well simulated in my MF configuration.
