MobiFlight Community Support

Hi. I am a newbie so perhaps you can help. I have an Arduino Mega and Mobiflight connector and fsuipc registered, building a generic GA cockpit. The printout of offsets I have shows 0892 for Eng 1 start switch, so I used it and it will turn left mag off and on but I don't understand what to do for the right, both and start. 1= right, 2 = left etc. Can you please help. Thanks

Hy, the offset ist correct. In the config of mobiflight, by "ON PRESS" the value of the funktion. ( Off, MR, ML, B, Start). by "ON RELEASE" nothing.
For mor helps, or send config, contact me. I am german and problems with english. But i can help.

Here the link to screenshots of the configs ....

I am build a single engine aircraft. the second configs for Engine Off an Engine Start is only, when i change for exampe two engine Aircraft, that i can start also ...... is the same config with the offset of engine 2 from the offset list ....

Hi. Thanks for getting back to me. I did not have a chance to try it but I think I understand. 1 Pin for each, Off, Left, Right Both and Start and use the 1 or 2 or 3 etc for the on press. Use [Do nothing] for the On Release. Would I use the same method for Fuel Tank Selector?
Thanks again.

Hi,

the ON RELEASE-Funktion can normally be unnoticed with multi (rotary) switches, because if you switch von position 1 to 2 you send an ON PRESS Event on the 2 so you need no ON RELEAS Event when leaving the 1. Same if you turn from 2 to 3 and so on.

A Fuel Tank Selector ist the same: LEFT BOTH RIGHT. This can be realized with a rotary-switch - then you don't need the ON RELEASE function. But if you take an ON-OFF-ON-switch you have to use the ON RELEASE function because the OFF-position is the BOTH position (the one in the middle)

Stephans Information is 100% correct.....
So If you use a Rotary switch for exact 3 Positions you "can" work with a release command and you can save 1 Wire and one config.... BUT This is NOT recommend

It will work but if you plan to use the "Mobifligh Auto Sync function" then you have a big problem.

So to prevent problems in the future i recommend to use always on Press for Multi Rotary Switches.
( Only the 2 Position switches can be done with a release logic without problems)

In same way its high recommen to work with ON/ON/ON Switches instead of ON/OFF/ON Switches in other situtions, too. ( Like the B737 EFIS ADF Selectors or the APU Start Switch)
The "Auto Sync Funtion" not support a self build "release" logic ( And will NOT support it in the future, too) !

Hi again. what you are explaining makes sense but I still can not get it to work. I have done 5 configurations, with separate pins to Ardunio + ground. Off, right, left, both and start. I used 0892 and a separate value for each. 0, 1, 2 etc for On Press and nothing for On Release. I thought perhaps the rotary switch might be be defective, but I ran a jumper wire from ground terminal to the other terminals and still nothing. The ground wire is common on the switch. I was planning to use another rotary switch for Eng 2 but it is not programmed or hooked up yet.
Thanks

Hi. I figured out that the ground wire had an internal break. Stupid little problem caused all the fuss. Thanks to all that responded.

I hope you can help I have wired a rotary switch for the magneto with off R L both and start using the offset 0892 and 0 1 2 3 4 for each config line but it does not work.
If possible can you send me a copy of your config so I can see what I am doing wrong
kindest regards

@ TGFSC

More informations.

Sim... FSX ?
AddOn Aircraft or Standard Aircraft ?
Configuration ?? Typ, Size , Parameter

also confirm Switch itself is working correct.... Test with a other function or checkout the DEBUG String !

Thank you for your quick reply, I am using FSX on the standard Cessna 172. I have tested the Rotary switch and the rx led on the board flickers when I turn the switch
kindest regards

sorry I am not at the simulator computer so I cant give you config details until Wednesday can you tell me what they should be, that is what I think I am doing wrong
kindest regards

Sounds good.

For Standard aircraft FSX the offset should be correct.

Now check you have generate 1 Button Device for every single detent ( 5 in your case i think)
Then check that every detent is wired to the used pins.... for example 0 Position to Pin 5.... 1 Position to Pin6 and so on ( the 5 Pins you use for the created button devices)

Finaly you need 5 Configs for that switch....
Config 1 will use the "Button" Device of Position 0 ( Off Position) . Use FSUIPC Offset as Typ... Size 2 Byte Typ INT Parameter 0 (On Press)
NOT select a action for On Release.
Do the same with config 2-5
All Use the same Offset Size Typ.... But will use different Devices and Parameter.
Config 2 will use Button Device of 1 (right) position and will use Parameter 1
Config 3 will use Button Device of 2 (Left ) position and will use Parameter 2
and so on......


Last Note: Blinking of rx LED is NOt a indice for a correct working button.
To find out if a button work correct you should use the DEBUG String ( Enable Logging mode for this)
OR
You build a simple testing config..... For example you send key presses for every detent or you controll a other thing like Position 0 Gear Down - Position 1 Gear Up - Position 2 Gear Down and so on.....

The final target is to confirm if Mobiflight recognize every detent correct ( Not if Arduino see the button we want to check the dataline to Mobiflight here)!

Hi Pizman
Problem solved, I used the wrong pins on the board, I used RX TX 19, 18 17 16.
Thanks for your help
Kindest regards
