Offset might have been the incorrect term here. I give an example: KOHLSMAN_INC is 65883, KOHLSMAN_DEC is 65884. With these values I can access the baro setting directly from SIOC by sending FS control 65883 or 65884 when turning a rotary encoder.
Logging gives me for example this:
*** EVENT: Cntrl= 65883 (0x0001015b), Param= 0 (0x00000000) KOHLSMAN_INC <-- I can see FS control 65883 for KOHLSMAN_INC
FSUIPC Control Action: Ctrl=0, Param=0
I built a transponder with 2 rotaries, one for the higher two digits, one for the lower two. The function I want to use is the one I mentioned above, and it was added with one of the FSUIPC updates after the 2003 list was written (at least the function is in FSUIPC, but not in the list). For testing, I have assigned four buttons, one for each function.
Log:
364453 Button changed: bRef=0, Joy=2, Btn=4, Pressed
364453 [buttons] 9=P2,4,C1055,0
364453 FSUIPC Control Action: Ctrl=1055, Param=0
364578 Button changed: bRef=0, Joy=2, Btn=4, Released
Here I don't see the EVENT: Cntrl= xxxxx for Xpndr High NN Inc, which increases the higer two digits.
Therefore I am looking for the FS controls (is that the correct term?) for:
XPndr High NN Inc
XPndr High NN Dec
XPndr Low NN Inc
XPndr Low NN Dec
And of course I did a search for transponder/XPNDR through all the FSUIPC documentation I have before posting here.
