View Full Version : Transponder display

Hi all,

I am asking if anyone using transponder display from FSUIPC offset. 0x0354
I am wondering if the digit changes when we press the numpad on XPDR?
There is joystick button assignment for those transponder numbers (0,1,2,3,4,5,6,7,CLR) in FMGS_Config.

Hi Vu, problem is reading the inputs as a 4 digit sequence.
I once saw someone with own hardware, who programmed something. I believe it was some old programming code, not SIOC or something object oriented. But maybe it's possible with SIOC too.

Thank michael1508. I have tried to study about SIOC and FSUIPC offset but seems most of tutorial has been removed.
There is an instruction from mobiflight forum, that we can use SIOC to send value from Jeehell to FSUIPC custom offset, then using Mobiflight to display this value on 7 segment display. However I do not know where to start with SIOC, which value to be filled in those fields?

I added first digit 1 and total 4 digit, then open Jeehell.ssi with SIOC shown as below

Lets say I want to reflect transponder signal from SIOC to FSUIPC offset 0x66F1.
So how to proceed ?

Thank you very much

Sorry Vu, I myself am not familiar with SIOC.

As far as I remember that guy programmed a timeslot, in which he captured all 4 single entries sequentially and then took that stored string and sent it to FSUIPC as one 4-digit number.
