Sorry, I don't know C#. Isn't the example of the interface in the SDK of use? Once you know which offset to use, what would be the problem?

 

Have you considered using Paul Henty's .NET DLL? It makes such things much easier -- see the SubForum about this, above.

Hi Pete, 

 

I am trying to read HDG but got some fantastic number like 121823238 however I can read speed and altitude normally. Could you please help me to solve this issue ? 

 

my delphi  code is :

procedure TFormMain.TimerUpdateTimeTimer(Sender: TObject);

var

  dwResult : DWORD;

  auiTime  : Array[1..3] of Byte;

  altitude:DWord;

  IAS: DWord;

  G_force: DWord;

  St: DWord;

  HDG: DWord;

 

begin

 

  FSUIPC_Read($3324, 8, @altitude, dwResult); //

  FSUIPC_Read($02BC, 4, @IAS, dwResult);  // 

  FSUIPC_Read($11BA, 4, @G_force, dwResult);

  FSUIPC_Read($0580, 4, @HDG, dwResult);  // 

 

  FSUIPC_Process(dwResult);

  Label4.Caption := IntToStr(round(altitude )) + ' ft';

  Label5.Caption := IntToStr(round(IAS / 128)) + ' kt';

  Label6.Caption := IntToStr(round( G_force/625));

  Label7.Caption := IntToStr(round(HDG*360/65536*65536));

 

Thanks in Advance

...

  Label7.Caption := IntToStr(round(HDG*360/65536*65536));

 

The arithmetic operations / and * have the same priority, so are obeyed left to right -- so you are getting

 

          ((HDG * 360) / 65356) * 65536

 

You need to use parentheses exactly as shown in the dox.
