    Joystick number

    Further to Pete's reply, the DLL facility is just a wrapper over the joystick scanning facility in FSUIPC provided at offset 0x2910. As Pete says, this can only read real Joysticks 0-15. I can see offset 0x3340 deals with Virtual joysticks but there is no wrapper in the DLL for this. You'll need to access this offset directly. I recommend declaring an offset of type BitArray (4 bytes) for each Joystick. Then you can directly access each bit (button) as being 'true' or 'false' without needing to do bitwise masking. Each joystick will be at increments of 4 from the base offset of 3340. e.g. 3340, 3344, 3348, 334C etc... Paul

    Offset's 3160, 313C and 3148.

    There is Aircraft Model which you could use in addition to the Aircraft Type... private Offset<string> aircraftModel = new Offset<string>(0x3500, 24) There is also Aircraft Name. This often includes the livery as well. private Offset<string> aircraftName = new Offset<string>(0x3D00, 256); The contents of these offsets depends on what the developer of the aircraft has written in the Aircraft.cfg file.

    Hi Quinch, This code doesn't look correct to me: string aircraftData = "({ATCID} - {ATCTYPE })"; It should have a $ in front of the string to use variable concatenation. At the moment this string would have the value "({ATCID} - {ATCTYPE })". You don't show your output code, but I suspect it's not outputting the 'aircraftData' string but something else. The code below works. You can try it for yourself and change it to fit into your code: private Offset<string> aircraftType = new Offset<string>(0x3160, 24); private Offset<string> aircraftID = new Offset<string>(0x3130, 12); private void Button6_Click(object sender, EventArgs e) { FSUIPCConnection.Process(); string ATCID = aircraftID.Value; string ATCTYPE = aircraftType.Value; string aircraftData = $"({ATCID} - {ATCTYPE})"; MessageBox.Show(aircraftData); } Paul

    Hi Pete, This is going to be a specific issue with using my DLL (or C# programming). I'll investigate further and help the OP. In the mean time it's best to move it to my sub forum. Thanks, Paul

    Simple offset extraction to Arduino

    Hi Emerson, I'm glad to hear you got it working. Congratulations on creating your landing gear product, and good luck with it. Paul
  6. I'm not sure an infinite loop is the best way to do this. You might have better performance using the event system. This monitors the LVar values in the background and fires an event when they change. Here's an example from another user... writeN1(varname, value) ipc.writeUB(0x66C0, value) end event.Lvar("B200CFuelCrossfeed", 100, "writeN1") writeN2(varname, value) ipc.writeUB(0x66C1, value) end event.Lvar("B200CRvsNotReady", 100, "writeN2") writeN3(varname, value) ipc.writeUB(0x66C2, value) end event.Lvar("B200CLBld", 100, "writeN3") writeN4(varname, value) ipc.writeUB(0x66C3, value) end event.Lvar("B200CRBld", 100, "writeN4") You declare a function that sets the value to the offset and then register this with the event system (event.Lvar). See the FSUIPC Lua docs for full details but in summary the call is: event.Lvar(lvarName, polling_interval_in_ms, function_to_run) If you prefer you can make only one function that is called by all the events. This would need to test the LVAR name (varname argument) and write to the correct offset. I don't know about the logging as I don't use lua at all. You'll need to ask Pete about that in the main support forum. Paul
  7. Good to hear that worked. These are the only official user offsets. However, if your application is only for your use you can try using the blocks marked as reserved. These are allocated to third-party software. For example 0x04E0 (88 Bytes) is for Project Magenta software. If you don't use that then you could try that block. Or there is a block from 0x6420 to 0x65EC (640 bytes) which is for PMDG aircraft if you don't have those. If your software is for general release (free or commercial) then you need to ask Pete (in the main support forum) for some offsets to be allocated for you so you don't clash with other software. Paul
  8. Hi Agoston, That's what the DLL does when you call ReadLVAR(). It's just a nicer way of using the offsets provided. Yes only one LVAR can be read or written for each process() call. That's just how FSUIPC works with LVARS. When you use ReadLVAR() in the DLL it does a process call. When you need to read a lot of LVARS then the time adds up. On my machine with FSX and default aircraft it takes about 20ms to get one LVAR. So reading 25 lvars will take half a second for me. No it won't make it faster. FSUIPC communicates on a single thread. The DLL is 'thread safe' which means if you use it from multiple threads and nothing bad will happen. But each thread will have to wait for the others to make Process calls. Only one thread can be talking to FSUIPC at a time. You could look into SimConnect. It's not very easy to use from .NET languages and the documentation is very poor for .NET. It might let you read LVARS faster, but I don't know. The LUA scripting in FSUIPC also allows you to read LVARS and also monitor them for changes (an LUA event is fired). You could write a LUA script to monitor your LVARs and send the values to user offsets where you can read them from your program. LUA scripts can only be run with a licensed copy of FSUIPC however. Documentation for the LUA library can be found in the Modules/FSUIPC Documents folder. Paul

    Negative Vertical Speed 030C offset

    You've declared the offset as an unsigned integer. That's why you are not getting negative values. private Offset<uint> verticalspeed = new Offset<uint>(0x02C8); My code again: private Offset<int> verticalSpeed = new Offset<int>(0x02C8); // 4-byte offset - Signed integer  That will fix it. Paul

    Negative Vertical Speed 030C offset

    You can post in the main support forum here: https://forum.simflight.com/forum/30-fsuipc-support-pete-dowson-modules/ BUT: There would be no point if my Example Application shows the correct value. Please try that first. If that works then your code is wrong, not FSUIPC. If you post the relevant parts of your code here I can check it very quickly. I can't help much without seeing the code. Paul

    Negative Vertical Speed 030C offset

    The code I posted works fine with FSUIPC4. I've test both 02C8 and 030C. Are you using the code above unchanged? If not, I'll need to see your offset declaration and the code where you read, convert and display the value. You should also try running the Example Code application and going to the form called "BC003: Reading and Using Offsets" under the Basic Concepts node. If this shows large values instead of negatives then you'll need to contact Pete in the main forum as something is wrong with your FSUIPC. Paul

    Negative Vertical Speed 030C offset

    The code below is taken from the 'Example Code' solution. It works fine for vertical speed (02C8). You can download this from the website: http://fsuipc.paulhenty.com/#downloads private Offset<int> verticalSpeed = new Offset<int>(0x02C8); // 4-byte offset - Signed integer protected override void timerMain_Tick(object sender, EventArgs e) { // Call Process() to get the data from FSUIPC FSUIPCConnection.Process(); // -------------------- // VERTICAL SPEED // -------------------- // FSUIPC Documentation says this offset is 4 bytes, signed (int) and holds the speed as metres/second * 256 // We need to convert back to metres/second by / 256 // Offset is 'int' so cast to double for conversion. double verticalSpeedMPS = (double)this.verticalSpeed.Value / 256d; // If you want to display as feet/minute a further conversion is required: double verticalSpeedFPM = verticalSpeedMPS * 60d * 3.28084d; // Display one of these on the form (this time rounded to 0dp) // this.txtVerticalSpeed.Text = verticalSpeedMPS.ToString("F0"); this.txtVerticalSpeed.Text = verticalSpeedFPM.ToString("F0"); } 030C is a copy of this offset, but it's not updated on the ground. It should work exactly the same as 02C8. Just change the offset in the declaration. Paul

    Simple offset extraction to Arduino

    Hi Emerson, The chkAvionicsMaster_CheckedChanged method is for reacting to when the user ticks the checkbox on the screen. I think what you want is to react to the things changing inside the flight sim. Your code should therefore go inside the Timer_Tick(). After the Process() call you can text the current value of the master avionics switch. You can then turn your light on or off. Something like the code below: (The code is placed after the existing line to update the on-screen checkbox): I don't know what you need to send to the serial port but I assume you do... // 2. Master Avionics this.chkAvionicsMaster.Checked = avionicsMaster.Value > 0; if (serialPort1.IsOpen) { if (avionicsMaster.Value > 0) { // Master switch is ON. Send command to turn on the light serialPort1.WriteLine("1"); } else { // Master switch is OFF. Send command to turn off the light serialPort1.WriteLine("0"); } } Note that this timer runs 20 times per second. If it's a problem sending data to the serial port that often then you'll need a variable to remember the last value of the Avionics Master switch. If the current value is the same as the last then you don't need to resend the same command to the serial port. For the landing gear you need to declare the offsets to read the gear position (See Offsets 0x0BEC, 0x0BF0 and 0x0BF4). Then in the timer, check the values and determine if the gear is up, down or in transit. Then send the commands to your serial port to turn the lights on/off. Paul

    How to get accurate G-force? VB.NET

    You're searching through the entire list, overwriting the results for each one. So you end up with the results for the last item every time. This might work if you only have one airport in range, but if there are more it won't work. You need to do something like this: ' Find Closest Airport that doesn't start with X Dim closestAiport As FsAirport = airports.Find(Function(ap) Not ap.ICAO.StartsWith("X")) ' Test if this is the Dept or Arrival Noairportlbl.Text = "Not in any airport" If (closestAiport IsNot Nothing) Then If closestAiport.ICAO = getDeptICAO Then Noairportlbl.Text = "" GreenText1.Value = "You are at your departure location!" GreenText2.Value = 10 ElseIf closestAiport.ICAO = getArrivalICAO Then Noairportlbl.Text = "" GreenText1.Value = "You are at your destination location!" GreenText2.Value = 10 End If End If Paul

    How can i track number of passengers ?

    Yes you can use offsets 0x3380 and 0x32FA. See the offsets documentation for details, but in summary: Declare an offset for 3380 (string with length 128) Declare an offset for 32FA (Short) It's important they are in this order. 3380 must be declared first. Mark them both as write only and put them in their own group (e.g. SendText). When you want to write text: set the text in 3380. Set 32FA depending on how to want the text displayed (see the docs). Process the "SendText" group. Paul
