• How to use the time of 80 MHz with the example of the soul base angular Position-buffer-Cont-Ext Clk.vi

  Hello:

  I use the card PCI-6602 and am a bit new to the use of timer/counters.  I use the Commission to measure the position of a quadrature encoder.

  I would use the time base internal 80 Mhz the map of 6602, but examples of LabVIEW will not allow that.  In the example, he States:

  2. call the DAQmx Schedule VI (sample clock) to configure settings of clock synchronization external sample Mode Sample and sample clock Source.  The sample clock Source will determine when a sample will be inserted into the buffer.  The 100 kHz, 20 MHz and 80 MHz time bases can serve as the sample clock Source.  The Edge parameter can be used to determine when a sample is taken.

  Is it possible to use the database internal time for my application?

  I have attached the example vi that I use.

  Thank you.

  Hi, Pat.

  

  The rate determines how fast the samples are acquired and put on the material buffer.  This value depends on the basis of time, which is specified by the source of the VI DAQmx calendar entry.  The default source on the PCI-6602 map is the on-board clock (80 MHz).  The rate must be a divisor of the source.  For example, 80 MHz, 40 MHz, 20 MHz, 10 MHz,..., would be acceptable values for the entry rate.

  So the answer to your question would be to remove the entry from the source and ensure that the rate is a factor of the source.  Leaving this entry unwired will use the clock shipped by default of the unit, as shown in the screenshot below:

  

  I hope this helps.

  

• How to use NI 9264 and NI 9205 with NI PXI-7813R and cRIO-9151

  Hello world

  I am currently working on an application in time real NI PXI-7813R (map FPGA) and NI PXI-8184 (on-board controller). They are all in an NI PXI-1031 chassis.

  I need to generate/receive analog signals.

  I already managed to use the SCB-68 with my NI PXI-7813R (FPGA card) to process digital signals. (Slot 0)

  Connector 1 and 3 of my FPGA I have respectively cRIO-9151 with NI 9264 for analog and cRIO-9151 output with NI 9205 for the analog input.

  • with NI 9264, I have on every 16 outputs-10, 5V (!) Isn't it supposed to be between-10 and 10V?), whether or not the vi runs. (But not when my PXI turned...)
  • with the NI 9205 module, I always get-32767 when the VI is running, regardless of pressure I apply. (I tested AI0 and AL10)

  Maybe is my hardware not configured properly? I did the configuration automatically, when I started the project, Labview detected the devices connected.

  Unfortunately, MAX does not seem to be useful because inputs and outputs are on the FPGA...

  Any idea?

  Thank you

  PS: VI on the FPGA is really basic, only read/write controls.

  Hello

  Back with the solution...

  My modules came! Each of them has been plugged in the wrong cRIO-9151.

  This must occur after the first configuration.

  I noticed when I right click on my fpga device > RIO Device Setup. I wanted to check the devices again, but crashed for Labview.

  I could also have seen 'Connector [number]' (automatically added by Labview) and the removal of material number (9205 or 9264) in the project and check if it really was what I had.

  Hope that my mistake will help someone in the future...

• How to use a structure of the event with a state machine

  
  

  I don't know exactly what you're asking, but it sounds as if you want a bunch of script tests and if the user says stop, to immediately stop the current test and abandon others?  I'll assume you know how to clear the table so that it will not abandon the others, so I guess that you have wrong to abandon the current test?  If it is indeed the case, the problem is that you are not able to spread the message of the VI FP main which is the GUI for the sub vi which is the test where the test may or not have a GUI (FP visible) of its own.  Threading is the first thing to come to mind, but it will be may not need the use of events.

  You can do this by passing a refnum of the stop button to the Subvi, where you can then add to wait to the structure of business event.

  I have attached 2 screws, mainvi.vi which is just a loop displays the number * 2 (number of seconds since the race) to be called subvi.vi and then check to see if the button is pressed.  mainvi.VI is in no way a state engine, it's just a simple loop for demonstration purposes.  subvi.VI just waits 2 seconds and leaves, this is a better engine State structured with an init State to start a case of survey to wait events and an exit status to clean.  You can change everything as you wish so that he can do what you want.  You will notice that even if subvi.vi is running, it will automatically end when you press the stop button.

  I hope this helps.

• RunTimeException when you use the timer and TimerTask.

  In the switchNext() method, it changes an image and some text in a Vertical management. When I run the application, I get a RunTimeException. However, when I have not used the timer and tested the method switchNext() with just a button method worked perfectly. How can I make it work with timer or another class that he will call every 30 seconds?

   time = new Timer();
  TimerTask task = new TimerTask()
  {
  
  public void run()
  {
  
      switchNext();
  }
  };
  time.schedule(task, 10000);
  

  It would be useful to know what Exception you actually get.

  However, I think that it is indeed related to the fact IllegalStateException the TimerTask is running in the "bottom", and you try to update your User Interface.

  If you change the code as follows, it will work the method on the event Thread and so he has access to update the user interface.

  public void run()
  {
  UiApplication.getUiApplicat () .invokeLater (new Runnable()

  public void run() {}
  switchNext();

  }});
  }

• How to use the capture and the print button

  I tried to figure out how to use the capture and the "print" button, or add or what you call. I press it and the whole page of a different color changes, so I try to cut the section I want but I don't know how to send it to the printer. Can someone help me with this. I'm not at savvy with tech stuff, but when I find a recipe or something and it doesn't have an option to print a certain area, I can't understand how to use it?

  Thank you

  Andi Starbuck

  That happens to me is, I click and drag to make a rectangle of yellow selection, and as soon as I raise my finger on the mouse button, the part I've selected is captured as an image, a new tab opens and preview before printing, the image display. I can use the installation of the Page or simply print. But if I close the preview, this temporary image vanishes and I'm back on the page where I started. You see something different?

• How to use the adapter from the wall with my Mac Pro laptop?

  How to use the adapter from the wall with my Mac Pro laptop?

  The AC wall connector is not compatible with the outlet on the MBP?  As the MBP charger will work from 100v to 240v, a transformer is necessary.  You need a converter that connects to the power outlet home and is compatible with your MBP.  You can buy the Apple travel kit:

  http://www.Apple.com/shop/product/MD837AM/A/Apple-world-travel-adapter-Kit

  Or you can use a single specific converter for the geographical area:

  http://www.Amazon.com/orei-grounded-universal-adapter-Singapore/DP/B004SCSV2U/re f = sr_1_4? ie = UTF8 & qid = 1460735377 & sr = 8-4 & keywords = us + in + uk + power + adapter

  (it is a UK USA example)

  Or you can get the converter that adapts the charger directly:

• Satellite M30X-122: how to use the headphones and speaker at the same time?

  Hello

  y at - it a possiblity to use headphones and speaker at the same time?
  When I plug the headphones into the Jack, the speaker is created off the coast of the moment.

  Thank you
  Peter

  Hi Peter,.

  There is unfortunately no way to use both headphones and speakers at the same time. This is because tghere's a disconnection physical power for the internal speakers when you plug in the headphones. It is not by software. The only way around this would be to dismantle the headphones Jack and solder connections that are broken when you insert the headphone permanently.

  Kind regards

• How to use a structure of the event in a Subvi

  I am using a structure of the event within a Subvi.  The Subvi has a table constructor that built tables and the structure of the event is used so that when the program runs, it allows you to change the elements of the array.  It works, but when I apply within a Subvi, it does not work properly.  This goes into a Subvi, because it will be part of a much larger progrram, so it must be modular.

  If you are using a structure of the event, it is not a Subvi.  If you worry about modularity, you should not use the structure of the event.

  You seem to have a fundamental misunderstanding of modularity.  An event structure must be placed in a while loop.  If you have a while loop in a Subvi, you have transferred control of your program to the Subvi.  You are not at this stage modular.  Your higher level GUI has no control.  You would have to create a stupid system of variables to pass data down to the loop to stop the loop and return to your main VI.  This is not a good design decision.

  Instead of searching for a way to make something broken, you should spend effort trying to understand what you really want to accomplish.  You should also spend some time to learn how to work the event structures.

  This application is small at the moment and it is already on the way to the unreadable.  It's a terrible thing to do for you.  Break these habits now.  variables are only when absolutely necessary.  Using subVIs to accomplish individual tasks, do not run the entire application.  With the structures of the event, use a value of stop button change event for will not be held hostage to the time-out.  If your variable is '2' in it, you're doing something wrong.  It has to be something different between set points, put it in the name.  If you want to make the subVIs, create an icon.

  But first and foremost, invest time in understanding dataflow
