Someone asked to see the Lua code, so here it is. This is the entire contents of 'logic.lua', which is the script for a gauge that has no visual parts to it. You just add this gauge to a panel and it runs the hardware. This isn't tidy code, it's technically still a work in progress.

Cool stuff and great integration with AirManager !!

I have a practical question : In AirManager I think you made an empty instrument and add this code in the the default empty instrument lua script, right ?

Then to activate, do you leave the light bulb yellow in AirManager desktop to enable this instrument or is it not necessary ?

Do you have a start order AM started before FSX/P3D or after ?

Bye

You have to add the instrument to a panel and start the panel. So I just added it to my Twin Otter panel and it runs when I start that panel. I don't think there is any special order of starting. I generally start AM and te panels first but there are also times when I stop them and restart, which still works okay.

Ok thanks.

I did this approach for the GNS530 I made. It is Arduino driven. I put the LUA code of Russ into a panel.
This panel can run even in debug in AM desktop (I have added some messages to see if the buttons actions and I see the logs in the console)
Then the panel is marked "autostart" with AM Desktop.

And yes it looks like AM reconnect to the sim. We can see a message "Searching for the simulator" if started before and "Connected to" after.
