Different input data to PXI6733 without resetting the unit

Hello

From the attached VI, I have init. the PXI6733 then it come out 2 samples to 125kHz.

I'm trying to 2samples each loop without resetting the output device. (Please refer to the attached VI)

For example,.

Loop 1, AO:0 = 1V, 3V (Analog devices PXI6733, Analog output channel 0)

Loop 2, AO:0 = 2V, 4V

Loop 3, AO:0 = 3V, 5V

..

..

change from loop to loop data, i.e. data changes dynamically.

And at the same time, I need to 2 analog samples acquired too, using the analog input device, PXI6255.

Because the initialization will take time, I prefer to ignore the initialization steps and release/acquire new data in each loop (2ms).

I have run out of idea and hope any1 here could give me some advice/idea. Your comments are appreciated.  Thank you.

Hello Eng Wei,

Attached, is an example that allows you to do exactly what you're trying to do.

What you need to do is to adjust the output level to the output you want. As you can see in the program, there are a few things you might need to change to your application, but the initialization happens outside of the loop and inside, simply by changing the value of exit and entry read.

  • Repair without resetting the screen?

    Hello

    I have a DroidX and my screen has been cracked recently when she fell on a tiled floor. I called Motorola and they screen repair but the technician I spoke with informed me that they would have to reset the phone to do this, which would affect my text messages I saved. Normally, it wouldn't be a big deal, but I have several text messages from my father, extending over more than 6 months, which are very valuable for me because he died quite suddenly two weeks ago.

    My question is: is there a way to repair the screen without having to reset the phone? I'm ready to buy a screen repair kit and give it a go myself to try to save these messages. They are the only things I have left of my father.

    Thanks in advance for any help you can offer me.

    Sorry to hear about your father. You have my condolences as well.

    In regards to your text messages, search the Android market, I think that it apps that can save your text messages and other information in case you need to factory reset your phone.

  • Reduce the length of the array without resetting the table

    An application for review of experience, I would like to use a table for the entry of the experimenter.  The experimenter type in the values they choose, usually less than ten years, and the LabView program to use each value based on the size of the array.  All is good on any other installation requiring more values and the initial installation, the table will grow well.  The following configuration should require fewer values that table continues to impose values for diversity is entered until the table is initialized on start.  A reset button resets the table obviously but requires an additional control, training of users and frustration when forgotten and values entered before resetting.  Is it possible, for example to remove surplus values, to reduce the size of the array?

    Moreover, can the tab or enter key to move between the values in the table?

    Try this. I don't have time to clean it up right now.

  • Is it possible to restore default color settings without resetting the preferences?

    Running InDesign CS6 and I accidentally changed the color settings (long story). Now every document I open past that comes with a profile mismatch warning.

    Help, please.

    Hello
    I found the place where exactly this may be small :).

    [HKEY_CURRENT_USER\Keyboard Layout\Toggle]
    "Hotkey" = "1".
    'Language Hotkey' = '3 '.
    'Shortcut page layout' = '2 '.

    Change the value of "Language Hotkey" accordingly.

    1 sequence of button enabled; Use Left ALT + SHIFT to switch between locales.
    2 key activated sequence; Use CTRL + SHIFT to switch between locales.
    3 invalid key sequences.
    4 If the default locale is Thai, the grave accent key activates / deactivates the input locale. otherwise the keystrokes are disabled.

    Another problem is that it sits under HKCU as well, same as if I pack this setting with MSI, it won't have a any use to me. Since then, installation is done using MSI localadmin account and HKCU is associated with the current session. If a new user who connects to this settting does not apply, and even if it rises "access denied" :(

    Hope this helps anyone with the same problem.
    Thank you.

  • Input data for digital indicator tab does not exist

    Hello

    I'm trying to define the range of data for the numerical indicators on LabVIEW 10.0.1. For some reason when I go into the properties of my digital indicator, there is no input data tab as explained on the Web site of NOR: http://zone.ni.com/reference/en-XX/help/371361H-01/lvhowto/changing_data_ranges_of_nu/. In addition, in the tab data type, there is a section for the range, but everything is gray. Any help is appreciated. Thank you

  • Time increasing while sending data via http repeatedly on the storm

    Hi all!

    My application sends data (in general, this is a picture of ~ 1200 Kb) to the server via http.

    The data are sent ok, but the when I send data several times (without leaving the application) the time devoted to writing the data in the outputStream develops. On first use, it takes usually ~ 50 seconds, the second seconds of ~ 70, the third seconds from ~ 100... I see this problem only on the storm, others (Curve 8900, Bold, Tour) are OK. The url is used on Storm is: http://xxxxxxxxxxxxx.com/mobile/mobile.asmx;deviceside=true

    Here is the code snippet:

    private static WSResponse send(byte[] xmlBytes, WSResponseParser parser) throws Exception {
    
            HttpConnection connection = null;
        OutputStream outputStream = null;
    
           try {
                connection = (HttpConnection)Connector.open(WifiChecker.getURL(URL), Connector.READ_WRITE, true);
    
                connection.setRequestMethod(HttpConnection.POST);
                connection.setRequestProperty("Content-Type", CONTENT_TYPE);
                connection.setRequestProperty("Content-Length", String.valueOf(xmlBytes.length));
    
                outputStream = connection.openOutputStream();
    
                int offset = 0;
                int chunk = DATA_CHUNK_SIZE; // 1024
                int len = xmlBytes.length;
                while (offset < len) {
                    if (offset + chunk >= len) { // avoiding OutOfBounds Exception
                        chunk = len - offset;
                    }
                    outputStream.write(xmlBytes, offset, chunk);
                    offset += chunk;
                }
    
                xmlBytes = null;
    
                String response = getResponseAsSting(connection);
    
                WSResponse wsResponse = null;
                try {
                    wsResponse = parser.getWSResponse(response);
                } catch (Exception e) {
                    throw ApplicationException.invalidWsResponse();
             }
    
                if (!wsResponse.isSuccess()) {
                    throw new WSFailureException(wsResponse);
                }
    
                return wsResponse;
    
            } finally {
                IOUtils.safelyCloseStream(outputStream);
                IOUtils.safelyCloseStream(connection);
                if (xmlBytes != null) {
                    xmlBytes = null; // notify VM it can safely free the RAM
                }
            }
    

    I thought it may be a memory problem, so I manually cancel xmlBytes, but which does not solve the problem.

    Any ideas?

    Thanks in advance,

    Arhimed

    P. S.

    There is no question about Simulator, only on a real device of the storm.

    MSohm, thanks for your response.

    Fortunately, I have just fixed the problem. The problem was not in the code above, but in the code that made the xmlBytes. I converted bytes of the image base64 and looks like I did it dangerously on the use of the memory.

    Thanks again for your attention to this thread!
