FSUIPC TCAS data

[Tiberiu]

Gentlemen,

I am trying to get FSUIPC to access TCAS data. I have tried this code in my gauge, but for some reason the TCAS data is empty. I checked with TrafficLook.exe,a nd there are aircraft nearby.

//In PANEL_SERVICE_PRE_INITIALIZE
FSUIPC_Open2(FSReq, &Result, Mem, Size);
//where I have these declarations right above the case statement
DWORD FSReq = SIM_ANY; 
DWORD Result; 
BYTE Mem[1024]; 
DWORD Size=1024; 


//in PANEL_SERVICE_PRE_UPDATE
FSUIPC_Read (0xE080, 96 * sizeof(TCAS_DATA), (BYTE *) ground, &Result);
FSUIPC_Read (0xF080, 96 * sizeof(TCAS_DATA), (BYTE *) airborne, &Result); 

FSUIPC_Process(&Result); 

Sincerely,

Tiberiu Brasov

The TCAS_DATA structure is 40 bytes in size. You are attempting to read a data block consisting of of 96 of these structures - that's 3840 bytes for each of each of the FSUIPC reads. You have only allocated 1024 bytes for FSUIPC to work with. Increase the allocation accordingly.
