WideFS and Wifi

[kaelastreet]

Installed widefs server on main PC in spare room. Installed WideFS Client on development PC in another room. All PC's are on a simple WiFi Network.

It works out of the box.

Installed FreeFD on development PC, it works too, and it does what it says it should do.

Darn, if this gets any easier I will hang up and go paint the forth bridge.

Nice to see you making progress, Kaela. Who really needs documentation, eh? ;-)

Hi Pete,

I am fighting a severe cold at the moment, so my thoughts may not be along the correct lines here but.

I have, as above, widefs client up and running on my development pc.

I have open, FSUIPC For Programmers, Page 17

offset hex 02BC, size 4, IAS(Indicated Air Speed)

I have adapted the freebie Visual Basic thingy (UIPC Hello) to read as follows:-

Private Sub Timer1_Timer()
Dim dwResult As Long
Dim auiTime() As Long
ReDim auiTime(4)

  ' If we wanted additional reads/writes at the same time, we could put them here
  If FSUIPC_Read(&H2B4, 5, VarPtr(auiTime(1)), dwResult) Then
    ' "Read" proceeded without any problems
    If FSUIPC_Process(dwResult) Then
      ' "Process" proceeded without any problems
          lbl1.Caption = Format(auiTime(1), "0000.0000")
          lbl2.Caption = Format(auiTime(2), "0000")
          lbl3.Caption = Format(auiTime(3), "0000")
          lbl4.Caption = Format(auiTime(4), "0000")
    Else
      ' Unable to "Process"
      lblClock.Caption = "Processing: " & ResultText(dwResult)
    End If
  Else
    ' Unable to "Read"
    lblClock.Caption = "Reading: " & ResultText(dwResult)
  End If
End Sub

I hoped I would see my Indicated Airspeed, but I see a repeating pattern of numbers that seem to bear no image of the flight sim model that is in progress.

It says, size =4, so I guess thats four bytes, 02BD, 02BF, 02C1 AND 02C3

The next offset is 02C4.... (agreed)

Someone point me in the right direction please....

' "Read" proceeded without any problems

If FSUIPC_Process(dwResult) Then

' "Process" proceeded without any problems

lbl1.Caption = Format(auiTime(1), "0000.0000")

lbl2.Caption = Format(auiTime(2), "0000")

lbl3.Caption = Format(auiTime(3), "0000")

lbl4.Caption = Format(auiTime(4), "0000")

02B4 is not 5 bytes long, only 4. You want to read it into an Integer, not an array. You don't want to print each byte separately -- it is one binary value. And it isn't the indicated airspeed, it is the Ground Speed in units of 1/65536ths of metres/sec. Please re-check the tables in the programmers guide. You are reading something awafully badly it seems.

It says, size =4, so I guess thats four bytes, 02BD, 02BF, 02C1 AND 02C3

It is one integer of 32-bits wich occupies 4 bytes 9a byte is 8 bits, 4 x 8 = 32). You also aren't counting correctly. After 02B4 comes 02B5 then 02B6 and 02B7 -- not that any of that is relevant. you don't want 4 separate bytes, you want one 32-bit value.

Why are you counting byte addresses in 2's in any case?

If you want the IAS that is at 02BC not 02B4.

Please do take another look at the information provided. You can also try FSInterrogate2 which is highly instructive.
