Hi Again.
Feel free to do this or not..... I just make recommendations. If you can life with the issue then accept it.

Just about your awnser.
Your right ! This is a INT and a Transform entry can NOT result in something else like a INT .... So no string.

For example this formula will NOT work in "transform" : if($=80808,---,$) or if($=80808,'---',$)
BUT
Mobiflight got for this the COMPARE Tab !
Compare is exactly for this situation and result always in a string instead of a INT.....
There you can do this .... Whatever with a formula or with a direct entry in the THEN and ELSE fields.
If you use a formula get sure the "string part" is written in correct syntax ! In a if(a,b,c) format the String result must be within that symbol >> ' << like 'text'

Have fun !

Pizman, you are the MAN!!!!

Got the dashes"-----" working for VS and got it so it says "Std" on the QNH display when set accordingly. Will work on the HDG and SPD ones later, they will need another Offset to get it working because of the way the push/pull Lvars work. But this is great. Thank you so much, I knew there had to be a way, and when it failed in the Transform area I didn't even try anything in the compare spot.

Have a great day!

For more added realism, redesigned someone's mod for a military plane to work with the Airbus detent system. This works on the Aerosoft Airbus bundle for FSX for sure, not sure about other sims or planes. It fits into the Hotas X throttle base and replaces the original factory part. The lack of a detent in the right spot has been causing me problems when I come in to land.

I think I'm almost finished with this project, just in time to get back to work on Friday, lol. Have fun all.

i am so lost i got mobiflight to work with pmdg but trying to figure out how to do lvars for airbus a320. all i am really needing is how to do the led for the autopilot and the 7 segment displays. I tried using the script joe wrote but nothing happened reference below. i tried doing the led for the FD. that is part of the script i used

-- lights up when FD is active
function FD_ind()
FDyn=ipc.readLvar("L:AB_MPL_FD")
ipc.writeUB(0x3341, FDyn)
end
event.Lvar("L:AB_MPL_FD",100,"FD_ind")


And then setting my mobiflight to offset 0x3341 value type INT size 1

in the fsuipc.ini I added the name of the file to the lua file

here is my whole script from joe

I'm not sure if any of what I posted for people will work with a PMDG plane. This stuff was for the Aerosoft Airbus. So I have no way of telling if those Lvars will work for that plane. I know there are some PMDG guys floating around.

However, if the thing about PMDG is a typo, I noticed that you put the lua file name in the FSUIPC, but did you also start it?

Bellow is the section from my particular FSUIPC, don't copy it exactly, this is for my setup. But you not only have to list the lua files you are using, you also have to start them.

[LuaFiles]
1=APBoard
2=display vals
3=Indicators
4=ipcReady
5=linda
6=log lvars
7=Switches

[Auto]
1=Lua APBoard
2=Lua Indicators
3=Lua Switches

The portion above that says [Auto] is what starts the LUA's, in my case I have three for the panels I have made. This starts the LUA file whne I start FSX, however if I change part of the LUA you have to restart the Flight sim, so it could get frustrating doing it my way, but for me it made the most sense at the time.

One other suggestion, start with just one thing, get it working, then add to it as you build mor confidence that the things are working. All in one go you have no clue what to change first, I had one instance where I accidentally typed a "9" somewhere in the script and until I found that one character, the LUA wouldn't start. I had everything working one second then nothing. Becareful and good luck.

Normaly a cockpitbuilder not change something in the LUA script if he finished the Cockpit. So this problem occure only while building and testing phase.

Whatever.... If you read the FSUIPC Manual and some Lua Tutorials you will see...... there are much more ways to Run/Stop Macros or Scripts.

For example instead to the AUTO System ( That start your Mods at beginning with the Sim) you can as i know set them to a specific Aircraft.
Means if the Aircraft e.g. "PMDG B737 NGX Winglets" is loaded then FSUIPC detect this and then run all scripts you define for that. If you end the flight and you load a C172 then the scripts are stoped and e.g. other scripts you locate for the C172 get started.

You also can Start/Stop scripts by a Button or Key command. Like a hidden Switch in cockpit.... First press start the scripts.... Second press stop them or so.

so i have gotten the buttons and leds to work now trying to figure out how to get my 7 segment display to display the heading and altitude. i have the altitude showing up but it will not update when i change the altitude it stays at 7000


function ALT_SET(offset, value)
ipc.writeLvar("AB_AP_ALT_Select", value)
end


function AP_Alt_Setting()
Altitude_Set=ipc.readLvar("L:AB_AP_ALT_Select")
ipc.writeUD(0x07D4, Altitude_Set)
end
event.Lvar("L:AB_AP_ALT_Select",100,"AP_Alt_Setting")

I don't see an event.offset() line to make the function ALT_SET actually run and change anything.
