Hi, I have for many years had lines like this in FSUIPC4.ini:
14=P2,0,Cx0100341D,x01 -{offset byte set, offset 341D}-
15=P2,1,Cx0100341D,x00 -{offset byte set, offset 341D}-
16=P2,2,Cx0100341C,x01 -{offset byte set, offset 341C}-
17=P2,3,Cx0100341C,x00 -{offset byte set, offset 341C}-
Now with FSUIPC5 there is a problem: after a few minutes the buttons stop working, and lines like this are written to FSUIPC5.log:
264031 Exception 20 "DATA_ERROR", Ref 9702, Index param 1 on write SetData for "CABIN NO SMOKING ALERT SWITCH"
264078 Exception 20 "DATA_ERROR", Ref 9704, Index param 1 on write SetData for "AVIONICS MASTER SWITCH"
264078 Exception 20 "DATA_ERROR", Ref 9705, Index param 1 on write SetData for "PITOT HEAT"
I have a button for toggling pushback with no problems:
9=P4,6,C66483,0 -{TOGGLE_PUSHBACK}-
