  Hello

  I put t know if the touchpad software includes this option.
  You should check this in the touchpad options.

  You can find it in:
  Control Panel-> mouse-> tab advanced-> button Advanced settings

  But in my case, this option does not exist.

• Simulate the entry

  Hello

  To check my software, I want to simulate some signals on the entrance of the simulated NIDAQmx Council. Is this possible?

  I created the jury simulated in NI MAX, but I know not how to simulate the signal on the inputs and run my software (in C language) in order to acquire the data.

  Thank you

  Theinput signal of the simulated device is built-in, you can't change it. It is better to write your own piece of code that simulate the signal.

• Simulate the sine wave using LabVIEW FPGA with NOR-myRIO and display in real time

  Hello

  I'm relatively new to LabVIEW FPGA. I am trying to test (and later apply) controllers high speed on myRIO.

  At this point, I'm trying to simulate the sine wave from 1 to 10 kHz using Sinewave generator VI express. I also intend to display the sine wave on the time real (RT) using FIFO. However, I had a bit of trouble to understaing various synchronization parameters.

  1. how to encode information about the sampling frequency generating sine wave? (The side FPGA vi requires only the frequency of the signal and possibly phase and does not rate update lines)

  2. how to estimate the number of items in a FIFO? (that is, the relationship between the rate of updates to loop (RT), the signal frequency, sampling frequency and the number of items in the FIFO)

  It would be great if we could share a very simple program (side host and target) that did something similar.

  Thank you

  Milot,

  I think the problem is the type of data in your FIFO. Your FIFO is configured to use a data type of I16. The problem is the number, it displays only ever will be-1, 0 or 1. To resolve this problem, you must send the sine wave as a fixed point data and convert it to a double on the side of the RT. This should significantly improve your resolution.

• Use the toggle button to simulate the Ctrl key now

  Hello

  I saw someone asked something very similar before, but nobody seemed to know the solution.

  I was wondering if it is possible to use a toggle button to simulate the CTRL key now, the idea being that the user could then zoom in on a rectangle of their choice on a field without having to press the button themselves. I know that you can use the FakeKeystroke function to simulate support that the key however is possible that it may be held?

  Thank you

  I forgot one thing. You must handle the case when you have a real EVENT_DOUBLE_CLICK. In this case, you don't want to reset the keyboardState. Here's the modified code.

  char oldKeyState [256] = {0};
  
  char newKeyState [256] = {0};
  
  int isFakeDouble = 0;
  
  Zoom CVICALLBACK int (int, int int event, control panel,
  
  		void * callbackData, int eventData1, int eventData2)
  
  {
  
  	HWND hwnd;
  
  	toggleButton int = 0;
  
  	switch (event)
  
  	{
  
  		case EVENT_LEFT_CLICK:
  get the current state of the keyboard
  
  			GetKeyboardState (oldKeyState);
  
  			get the State of the toggle button
  
  			GetCtrlVal (panelHandle, PANEL_TOGGLEBUTTON, & toggleButton);
  If (ToggleButton)
  
  			{
  
  				create the new copy of the keystate
  
  				memcpy (newKeyState, oldKeyState, 1);
  Active control key.
  
  				newKeyState [VK_CONTROL] = 128;
  
  				SetKeyboardState (newKeyState);
  generate left mouse button events that will be holding the CTRL active
  
  				SetActiveCtrl (panelHandle, PANEL_GRAPH);
  
  				GetPanelAttribute (panelHandle, ATTR_SYSTEM_WINDOW_HANDLE, (intptr_t *) &hwnd);)
  
  				isFakeDouble = 1;
  
  				SendMessage (hwnd, WM_LBUTTONDOWN, 0, 0);
  
  				isFakeDouble = 0;
  
  			}
  break;
  
  		case EVENT_LEFT_DOUBLE_CLICK:
  mouse event generated will be taken as a double click. restore the old state of the keyboard
  
  			If (isFakeDouble)
  
  				SetKeyboardState (oldKeyState);
  break;
  
  	}

• No option to simulate the peripheral cRIO after installing Labview and RT/FPGA Modules of downloads (lack of driver support?)

  Hi guys -.

  Basically, I need to simulate a cRIO device without yet having equipment on-site, like this:

  How to simulate the FPGA hardware target using with LabVIEW Project Explorer

  Instead, I only get the options presented in the attachment "Add Target Options.jpg.  I guess it's because of missing drivers, which I assume is due to an error that I made during a recent new LV installation installation went like this: I downloaded (not diskettes) and installed the following (in this order, the latest versions all around):

  (1) LabView development system

  (2) real-time module

  (3) FPGA module

  (4) NEITHER-RIO (previous installation-by-installation)

  (5) DAQmx

  At the end of (1) and (2), I got the screen shown in the second attachment ("Drivers Installer Message.jpg"), but could not able to recognize the folder "device drivers OR" (I also downloaded), or one of its subfolders.

  According to me, I'm missing an obvious option to load the necessary drivers after installation, but can't seem to find reference to it in the forums.  Could someone give me a little help in the right direction?

  Thanks a lot and have a nice day.

  
  

• Trying to simulate the device USB-6366 (without success)

  I read through the tutorials DAQmx and MAX about the simulation of the device, but I can't yet find a way to effectively simulate the acquisition and generation of a signal using a device USB-OR-6366.

  I am a (given at the entrance of this VI) signal using DAQmx Write and then use DAQmx Read to read the signal captured from the internal memory of the card (which has a buffer of 32 MS). To do this, I created a task with DAQmx I feed in the writing block.

  I know that the approach is most likely wrong, but I can't understand not just how to do this in a simple way and documentation of NOR is anything but simple. All I want is to

  (a) test using 2 digital inputs to capture this signal by the device and then read what she has gained from its internal buffer

  (b) send the same signal to 2 digital outputs the signal output again.

  See you soon

  Yes! the simulation is designed to allow you to write a program and check that it works theoretically even if you do not have the material physically available. It has no interface programming to influence on the what the reading functions will return simulated data. And write the function has no notable effect anywhere, working as a receiver of data in nirvana. It is always useful because you can test software without getting all kinds of errors on the non existing hardware access attempt, but it has its limits, of course. However, a programming interface for manipulating that which and how the data are simulated, while it would be a very interesting feature, is almost certainly to complicated not only to implement but also to use.

• Programmatic checking for the presence of sbRIO in the network

  Hello

  I am looking for guidance (example code maybe?) to perform the following tasks programmatically:

  -check the presence of sbRIO target in the network

  -If so, connect with target & deploy the shared library Variable hosted in my Windows PC

  -If not, delete connection errors and make sure that SVs are not deployed (or cancel the deployment if necessary)

  The application must be able to continue with operation "No. HW" If sbRIO is not detected. My fight is how to check the presence of RT HW in the network and how cancel the deployment of the SVs and so no error is reported and the app can proceed free of charge with the simulation code.

  Thank you!

  Jorge

  Hello jorgeinSD,

  I would recommend that you take a look at the range of available in the Palette of LabVIEW Real-time System Configuration. Specifically the Find.VI looks like it is exactly what you want to use to detect the sbRIO is available on the network. This VI is can be found at the following location

  Real-time > utility RT > System Configuration > Find.VI (systems)

  This VI will return a list of all systems on the network. From there, you also use other utilities available in the palette of the Configuration of the system.

  See you soon,.

• Simulate the structure of the event in the LabVIEW base?

  I have a basic version of LabVIEW (v8.6) who doesn't have the structure of the event. I found it was quite embarrassing monitor the status of several controls (action after clicking a control depends on the State of the other control (s)). Especially if I want to add another function (control), the effort exponentially increase with the current number controls

  I had an idea to simulate the structure of the event using "shift register. First, I will provide all the values for the controls in a cluster. Then I'll put the cluster in a while loop and compare the value of the cluster to its previous value (xor the registry change). If the result of the comparison is false (none of the control is changed), the program moves to the next iteration. If the XOR result is true (one of the control has changed), then the program goes into code (it will pass what control has changed and the entire cluster) event management. So for each change of control, we can write an independent code to process the event. After processing of the event, the event was allowed.

  Here are some of my ugly code currently used to monitor multiple controls. And I think rewriting using above idea so there is less chance a hiden bug.

  Comments, suggestions?

  I'm not quite sure what I'm looking for on your photo of your block diagram because it seems that only the lower quarter right in your code.  I would do the following to detect a change in a cluster without the structure of the event control:

  

  The basic package include the notifications than us?  You can put your "event management" in another thread by this method:

  

  The advantage here is your main loop of the program is not "bogged down" every time that a change in your cluster held.  It also allows to separate the code so that it is cleaner.

  Hope that helps!

  I would really appreciate the help.

  Thank you very much

  I searched for a while, but I don't remember the forums where I originally found this VI so I can't give credit due.

  It is similar to the VI you posted simulating a keyboard, but it would proably your needs better

• Simulate the PXI-1033

  Good afternoon

  I need some clarification on the simulation of PXI via MAX.   I have several PXI modules and a PXI-1033 (integrated into the PCIe MXI) chassis on command.   As they will take several weeks to arrive, of course, I want to simulate these devices and to start building screws

  If I understand correctly the information contained in the knowledge base and forums, all I have to do is to simulate modules PXI themselves in MAX and nothing to simulate PXI-1033 chassis.

  Is this correct?   Guarantees as to any would be greatly appreciated!

  Sincerely,

  Zach

  Hey Zach,.

  You are right. We cannot simulate a PXI-1033 chassis, but because it's just an expansion chassis, there is no need to. You can simulate the modules themselves in MAX under DAQmx devices and then you should be able to start writing code.

  Good luck and thanks,

• How to load the Calibration file Agilent Instruments LabView 2012

  I'm using a vector Network Analyzer. Calibration is essential to give our creditbility of measurement results. In our case, we use Agilent instruments. Newer models allow certain calibration profiles be saved as States of calibration. These files are saved to the local hard disk of the unit and are loaded when needed.

  What is the equivalent to set all the parameters of calibration in this .cal file in the Agilent with Labview 2012 instrument?

  I downloaded the driver for my instrument and even ran the sample programs. It works fine but the calibration is set to the preset state that makes my whole system inaccurate.

  It should look like this (assuming that it's a NAP you use):

  

• Determine the presence of a device

  Y at - it a simple method to test for the presence of a device?  I have a chassis 9172 that I sometimes forget to put on for my mistakes of LabVIEW VI on the first time he's trying to do something with the material (and I need to resart the VI and re-enter the selections of GUI ).

  I would like to find a nice simple way to test to make sure the cassis is connected to the PC and turned on and if it does not give a not so subtle remicer to do before the real test of the code portion.

  Any ideas?

  You can look at this thread. Also, what kind of communication do you have in your application now? What devices you expect to be there? I have to assume that your applications run if the chassis is running. So you knew the equipment that connect you with now. Any request for State of the any of these devices does not suffice for you to determine if the chassis is here or not. If you can connect and get an answer, you're good to go. If this isn't the case, you must create a user switch on the chasis, connect or other problem.

  For your application, you can use an architecture of producer/consumer or a state machine which would allow you to stay in the initialization state before continuing, if you cannot communicate with the device.
