  1. In the FSUIPC_Write statement (VB.NET)
  2. What is the purpose of the token variable? Thanks
  3. I've checked the ini file but the AxisCalibration=No was already set. I've deleted the ini file, and restarted flight simulator and the problem was solved. Later I noticed that the problem was due to an overflow (the value of the elevator position control went beyong 35000) This caused my program to hang, when i restarted the program the calibration was enabeled, however not shown in the ini file. Thanks!
  4. Hi There, I've programmed the Elevator Position Control (0BB2) in VB.NET, I'am using a potentiometer in a real B727 yoke. The calculation in my program is correct and also a value between -16384 and +16384 is send to FSUIPC. However when i check my FSUIPC Log files I can see for example: 5104500 Elevator input=-16235, calibrated to -9387 FSUIPC seems to calibrate my input, something I don't want. Is there another offset for the Elevator Position Control without calibration, or how can I fix this? Thanks a lot
  5. In which magazine did you find these curves?
  6. Hi Pete, In mean time we've managed to get most things working. However we have a few questions. We are experiencing delays of +- 3 sec on the commands given, probabely due to unefficient programming. Do you have any FSUIPC related tips concerning a more efficient programming? (Note that there is also code included for the acquisition of voltages). Second question: We are getting the voltage values in double format, this means a lot of numbers behind the floating point, however, flightsim requires a Short as input, this means we are loosing all numbers behind the floating point. Currently we devide the voltage input by the max voltage input (so this means max = 1) and * 16348.

  8. Hi again, I checked the logs, it seems that it wrote only 1 byte (8 bits) (so that explains why 64 works as I can have any number between 0 and 255). The variable is an integer or S16 (16 bits) so i'am missing one byte. Here is a brief overview of all VB.NET variables: http://en.wikibooks.org/wiki/Visual_Basic_.NET/Variables#Short The problem is that it's not clear to me how to specify the size in the FSUIPC_Write sentence. Possibility N°1 ---------------- Using Short --> Short: 16 bits (2 bytes), stores integer values from -32,768 to 32,767. It seems perfectly suited. Code: Private Sub Button4_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click Dim dwOffset As Integer Dim Param As Short Dim ThrottleToken As Integer Dim Result As Integer If FSUIPC_Open(SIM_ANY, Result) = True Then dwOffset = &H88C Param = 245 FSUIPC_Write(dwOffset, Param, ThrottleToken, Result) FSUIPC_Process(Result) FSUIPC_Close() End If End Sub It works perfectly, however it has an overflow for Param values > 255. The log files show a change from 0x0 to 0xF5 for the offset 088C. 15664344 Monitor IPC:088C (S16) = 0x0 15667759 Monitor IPC:088C (S16) = 0xF5 Log: 16909715 WRITE0 [P3728] (failed, read-only!) 330A, 4 bytes: 02 00 00 00 16909815 WRITE0 [P3728] (failed, read-only!) 330A, 4 bytes: 02 00 00 00 16909916 WRITE0 [P3728] 088C, 2 bytes: F5 00 16915053 WRITE0 [P3728] (failed, read-only!) 330A, 4 bytes: 02 00 00 00 16915153 WRITE0 [P3728] 088C, 2 bytes: F5 00 I don't kow what the 330A offset does here, i never called it. The 08C offset now works with 2 bytes, however, it still had an overflow for values greater than 255. For example 256 in hex this would mean 100 (255= FF). The VB.NET debugging gives nothing.
  9. How can we pass this size in a vb.net FSUIPC_Write statement? There are only 2 possibilities in the SDK: - FSUIPC_Write (ByVal dwOffset as Integer, ByVal Param As Integer, ByRef Token As Integer, ByRef dwResult as Integer) As Boolean - FSUIPC_Write (ByVal dwOffset as Integer, ByVal dwSize As Integer, ByVal Param As Byte(), ByRef Token As Integer, ByRef dwResult as Integer) As Boolean I'am currently using the first possibility, without the size tag. However when I use the second one, what do I have to fill in 'ByVal Param As Byte()' ? Example?
  10. Hi All, I am trying to make the throttle lever ENG 1 working using VB.NET. I wrote following code and it works, however... ------------------ (088C) -> Between -16384 and 16384 ------------------ Private Sub Button4_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click Dim Result As Integer If FSUIPC_Open(SIM_ANY, Result) = True Then Dim ThrottleToken As Integer Dim ThrottleValue As Integer = TbTH1.Value Label1.Text =TbTH1.Value FSUIPC_Write(&H88C, 64, ThrottleToken, Result) FSUIPC_Process(Result) FSUIPC_Close() End If End Sub When you push Button4 on the form the throttles are advanced a little bit. However when I try to replace the '64' in FSUIPC_Write(&H88C, 64, ThrottleToken, Result) to '8000' FSUIPC_Write(&H88C, 8000, ThrottleToken, Result), I'am getting following message : Arithmetic operation resulted in an overflow This is probabely because I use wrong variables. We want to try out the throttle by using a slider on a form. Does anyone has any idea how to avoid the overflow? In the future We will replace the number with a voltage value.
  11. I did'nt know it was an illegal key. Our final work is to convert a Cockpit Procedure Trainer (B727) (ex-Sabena Technics) into a non-motion flight simulator using Microsoft Flight Simulator. As I/O hardware we are using Data Aquisition Hardware of National Instruments (USB-6008 Student Edition). Using VB.NET we will try to couple the voltage outputs to MSFS using the fsuipc.dll. We already managed to load the voltages into VB.NET application. That's is more or less... How can we arrange this time-limited key?
  12. We've got the key from our mentor at school as this is an academic project. I'll ask this info from him.
  13. I'am having the same problem. I downloaded the v 3.53 version, it worked perfectly with fsinterrogate. When I registered it, fsinterrogate was unable to locate my FS, FSUIPC,... How can I solve this?
  14. Hi, We are trying the same thing. Using Data Aquisition Hardware (DAQ) from National Instruments we are trying to find a way to pass the voltage values to FSUIPC, directly if possible. If not using Visual Basic. However we do not have sufficient knowledge of LabView to know how we can pass the voltage values to visual basic. Do you have any idea how to do that, or do you have any other knowledge that can help us? It's for a school final work by the way.
