  1. Could it be that the information quantity is more than the USB can acquire? I'm not sure if on that computer I have USB 2.0. It's an old laptop from 2004 so it could be that it has only USB 1.1. edit: on second thought it can't be. I also tried a 3 kHz acquisition and it didn't work... I suppose the boards are broken.
  2. Hello, Background: I am trying to build an application to monitor the power line of a factory because it is very noisy and we get quite often line stops that affect production. I designed a data acquisition program in Labview using a NI-USB DAQ 6008. It works but the results are not satisfactory since I only have 3kHz per channel (I use 3 channels) so I don't get to see higher frquencies that probably are the reason of our problems. So I switched to NI-USB DAQ 6210. This way I have a 13kHz acquisition rate so I get acces to the 13th harmonic (b.f. 50Hz) and do some oversampling to avoid al
  3. Hello guys, I'm back in the LabVIEW business again. I have to do sort of intensity mapping. The only problem is that it has to be represented on a circle. To be more exact: I have a circular surface and I measure 8 points of temperature around. I have to represent a intensity map on a circle in LabVIEW. I saw that LV8.6 has a 3D picture control on which one can map a series of sensors. But since I only need a 2D surface I thought the 3D picture would be to complicated. Any ideas? Thank you
  4. QUOTE (hooovahh @ Apr 28 2009, 04:28 PM) It worked. Thank you!
  5. I don't know if it is the right area (or forum) to post this but I keep getting the following error when I try to open an .chm file: It says: "Impossible to open the file mk@MSITstore:..." I don't understand where that "mk@MSITstore:" came up. It is the same for every .chm file I try to open. How could I correct this. Any ideas?
  6. Hy, I have implemented the queue version and it works fine. New question: what would be a clean method to close my program? I have done this, but it does not work well. If I enable the Exit primitive it halts LV and closes all others LV application. If I disable the Exit primitive it stops the application but does not close it.
  7. QUOTE (Mark Yedinak @ Apr 6 2009, 09:29 PM) I actually don't mind if the calibration runs at the same time with the data acquisition, since my calibration procedure doesn't access any hardware. It just corrects the data stored in a file previously acquired. If the computer running my software has enough processing power they should run fine in parallel. @Neville D, JustinReina: I will read about queued message handler. edit: the example in the first folder runs under LV8.0. Thank you.
  8. QUOTE (crossrulz @ Apr 6 2009, 08:17 PM) I have done this and it works nice now. I'm still curios to learn about dynamically processes. QUOTE (JustinReina @ Apr 6 2009, 08:57 PM) @mross: that wasn't nice Like a few other people mentioned, your deal is you want parallel stuff to run ('tasks'). So use your event structure to dispatch these tasks (use multiple loops). Main Concept: Responisve GUI handling should be lightweight (i.e. no event response greater than, say 20ms). Try this concept: Best of Luck. -Justin could you save the VIs in 8.0 version, please?
  9. QUOTE (Michael Aivaliotis @ Apr 6 2009, 07:23 PM) Done. It works fine now. :worship: QUOTE (Michael Aivaliotis @ Apr 6 2009, 07:23 PM) Using an event structure is fine. The problem is you can't do what you want with the existing design. When LabVIEW is inside an event structure executing your subVI code, it is stuck in there and cannot respond to other user events like button presses. Actually, it queues-up events and executes them upon the next iteration of the while loop. If you want to be able to launch multiple UIs in parallel (provided that your hardware can be accessed in parall

    Save the potatoes! Each day are slaughter millions of potatoes around the world. Saving a number of potatoes can stop some catastrophes around the world. For the majority love is only a feedback. Each day the greed of full-cannibal Christians and Muslims and Jews and Buddhists and others exceed the compassion and the love towards the innocent potatoes(they will eat the potatoes).
  11. @mrross: I have the basic concept of wiring data. But in the main.vi I don't have any data to transmit to the called subvis. To stop the loop in the main.vi I have a button (Quiter) with an associated event handler. @jcarmody: I'm wondering also if my subvis are really closing. To close the VIs I'm using the same technique (button with event handler) like in the following figure: The vis can be closed from one Stop button. And also from the close botton (x) on the title bar. If I close a called vi from that button apparently it closes only the front panel but keeps running, blocking
  12. Hello, I'm doing a project wich will have a front panel with 3 buttons, each of them calling to execution another VI. Like this: (main.vi is calling calibrare.vi and achizitie.vi) main.vi: For some reason after calling one of them, executing and exiting the vi, the main vi doesn't respond anymore to comands. So, what si the best way to call a vi to execution?
