Visa resourse missing in pda module

i am creating a simple read and write ,rs232 program and then generating exe file from labview mobile module.when i am trying that exe file to run in wince compatible arm board , the com port controller(VISA RESOURCE) of VISA  is not visible.how to create com port controller that should compatible to pda module wince based.

Hello Greycat,
The subpalettes for the VISA and Serial subVIs are suppose to be
unavailable if your target is a PDA device.  LabVIEW loads a
seperate palette set for each target.  Since VISA is currently not
supported on the PDA, you cannot directly open the the VISA functions
or the Serial functions when you are targeting a PDA device. 
Instead, you can use the Serial Compatibility VIs, which then call the
appropriate VISA calls.

  • Is it possible to run AM Modulation in LabVIEW PDA Module?

    Hi All,
            I would like to ask about AM Modulation vis can run on PDA Module or not?Because as i mention that PDA screen is too small to see all the AM modulation waveforms.So i would like to know whether is it pissible to run AM Modulation on the LabVIEW PDA Module? If it is possible, please tell me that how should i modified my VIs on block diagram and how do i arrange all waveforms graph on front panel?
            Then, the AM modulation that i want to run is as shown in attach file.
             Thanks to all for your help.
    With Regards

    Hi Jpaul,
                 Thanks for your quite useful help. I am now able to manage all waveform in one tab control. But i still have some errors for my final year project. I am from Singapore Nanyang Polytechnic who do the final year project. My project is to transfer over the AM Modulation waveforms on the PDA device. But i still face on with some errors.My error is as following.
    (1) After i run my waveforms together with Tab control, the program that appear on the PDA is only too small and only can see half of
          my waveform.As i understand that all the text size must be greater than 20. And I chose the landscape screen for my tab control using.
          The waveform that together with tab control is as shown in attach file.
    (2) Then my PDA's internal memory is not enough space for running the new application and when i want to delete it, it is not possible to
          delete and there is error to delete. I would like to know how can i delete my NI files from my memory. My PDA model is HP iPAQ hx2700.
    (3) Then I would like to know more about what is the usage of NI CF-6004?  Is it like memory card for running NI
          waveforms on the PDA? Or if not what is it use for ?
                 I am strongly appreciate for ur help and i know that this might be so many question. But i am really no way to find this errors anymore.Thats why i have to ask to you. I will be thanks for all ur help. Thanks a lot
    Best Regards

  • "NormFltH is a missing VI or C file" when using PDA module

    To whom it may concern,
    I developed a VI, which containing some Digital Signal Processing (DSP) functions and digital filters. I want to download it to my PDA via NI LabVIEW PDA module. However, the system always prompted "NormFltH is a missing VI or C file". I don't know what such "NormFltH" file is. If I run this VI on my PC, everything works well unless I try to run it in my PDA device.
    Can anyone offer me some guidance or suggestion? Thanks so much for your valuable help.

  • Serial PDA function sub palette missing from Functions Palette in PDA Module 8.0

    Hi:
    I have a problem that I would like to solve without having to reinstall PDA module.  Under the functions palette, Instrument I/O ... I have the Serial Compatability sub palette there but the VISA and the Serial ones are now questions marks instead of a sub palette.  Has anyone had this problem and if so how is it fixed.   If I copy and paste the VI's from Labview 8.0 (for PC) to the PDA vi I'm writing, they seem to work fine but what a pain that is ... anyone have an suggestions?  Thanks

  • How to setup PDA module for wince

    I want to develop a PDA that with some measurements or analyze function, so i choose the Labview for PDA module.
    My hardware is ARM s3c2440(Samsung), OS is WinCE5.0. Software: LabView7.1
    I have developed the VIs for PDA module on the Pocket PC. I remember that I had to install EVC++ and Pocket PC SDK before I setup the PDA module.
    So I thought after I installed the EVC++ and the SDK for my 2440 board, I could setup the PDA Module as before. However, I found that the installation still have to find the Pocket PC SDK.
    How can I setup the PDA module with my 2440's SDK?
    Another question, can I develop the Labview PDA module in the enviroment of ARM s3c2440+embedded Linux(qtopia)?
    Thanks for have read this question, waiting for your guides.

    Depending on how the clients connect use the IPv6 prefix of their 6to4, Teredo, and/ or IP-HTTPS tunnel. Just keep in mind that it could become a long list...

  • Blinking property not available in PDA Module?

    Hi All,
    Is the Blinking property not available for a Boolean indicator in PDA Module?
    hellolv

    Perhaps you can help investigate this problem. I am attaching a zip file that has a sequence file and 4 VIs. The sequence has 2 steps, one that calls blinktop2.vi and the other calls blinktop.vi. Each calls a subVI that blink certain controls. Here is what I have found in experimenting with these.
    After starting the sequence editor if I run only the first step, skipping the second, then blinking will not occur. After doing this not other blinking property in any other VI called by TS will work either.
    I then ***shut down*** LV. Returning to my sequence I run the second step skipping the first. Now the controls blink. Without shutting down LV if I then execute the first step it also blinks.
    In the second step Blinking is first set to False before being set to
    true. What do you find?

  • HELP!!! ... need to get Window Handle using PDA module

    I am trying to find a way to get the current window handle using the PDA module.  I need this handle to call other function via Win dll's.  Has anyone done this before?  Any help would be greatly appreciated (using windows mobile 6.1 and Labview PDA 8.5)  Thanks
    Greycat

    Thanks Mike ...
    I understand that this function does exist, but somehow I am not writing my wrapper properly or calling the function properly because everytime I build my labview app I get a "GetForegroundWindow is a missing VI or C file." - I cannot for the life of me figure this out ... what I was really asking is if anyone has succeeded calling this function and getting the Window Handle.  What I really want to do is run my Labview program on the PDA in full screen mode with no title bar and no SIP button visible or accessible, but to my knowledge, that will take a function call to the aygshell.dll (namely the SHFullScreen function) and that function requires a window handle to work properly ... any more help would be appreciated ... Thanks again

  • Problem related USB Virtual COM PORT using PDA module 8.2 on Windows CE

    Hi,
    I am working on tranferring my application developed on LV 8.2 to a Single-board computer(SBC) running Windows CE 5.0. I am using LV PDA module 8.2 to achieve this. My problem lies in finding the port number of the Virtual COM Port on the SBC. I need to connect a USB RF modem from Maxstream to this SBC and to talk to it using VISA. I have installed the required drivers from Maxstream for converting the USB port to a virtual COM PORT. What is a way to figure out the COM PORT number on a Windows CE device? For a PC, I can see the COM PORT in the device manager but I do not know how to find this in Windows CE. . Also, I have tried using "VISA Find resource" function ..it works on a PC but I do not get anything in the Win CE device.
    Any help would be much appreciated.
    -Shruti

    Shruti,
    Is there a way to verify that the Maxstream driver successfully provides you with this virtual COM port? Essentially, what I mean is that if you did not have LabVIEW on this device, how does Maxstream prove that their driver is functional? Does it come with additional software that would be used to configure the USB RF modem? In any case, we would want to try opening any terminal program (like the hyperterminal) to determine what ports are listed for communication. I hope this is useful for you. Please post back when you are able to give this a try. Thanks,
    Mike D.

  • How to create a login interface in labview PDA module?

    How to create a login interface in labview PDA module? So that it checks with a list of usernames and passwords and allow to go to another VI?
    Anu

    Anu,
    I've attached a really short example that does something like what you're talking about.  It just compares the user's username and password a pre-determined username and password and then "logs the user in" based on that comparison.  Like Greycat said, you probably want to store this username and password info in some sort of file on the PDA that's in an encrypted format for both security and flexibility of your application.
    I hope this helps,

  • Labview pda module: how can I resize image dynamicall​y in an applicatio​n?

    Hello every one,
     I am currently working on the development of an application on a PDA (brand Nomad) and whose OS is Windows Mobile. So I am using the PDA module of Labview 8.6.My problem is the following one: in my application I would like to be able to load images (thanks to their path) in pictures indicators. I load images with the labview “function PDA Image File Load.vi” and then my problem is that images don’t fit with the size of the indicator, and so I am only able to see the left top corner of the image…Of course, I would like to see the entire picture, but I don’t know how I can modify or resize a picture with the PDA Module, where most of the property nodes (zoom factor, scrollbars…for picures) are not available.Has someone ever faced and fixed that problem?? Any help would be really appreciated!!   PS: Attached is one part of my application!

  • How to use PDA module to access the database of PDA?

    I want to develop a program which  can access the database of PDA by the pda module. give me some advice!
      thanks!

    It may help you to know how I add JARs
    1. I open my Project (myProject)
    2. I Mount the JAR to the FileSystem (like mypackages.jar = which includes com.mus.de.myClass.java)
    3. I Mount the File to the FileSystem (like c:\..myfiles..\myProject)
    3.1 I add the File to my Project
    4. I select File | New -> Classes | Main
    4.1 I typed "import com.mus.de.myClass.java" to refer to this package.
    4.2 I called some of the public methods

  • The binary file processing in PDA device (LabVIEW PDA Module)

    To whom it may concern,
    I created a VI application, which should read some binary files and transform them to waveforms shown in the Waveform Graph. I implemented it with Mobile/PDA module. This application runs successfully on my desktop, that is, on the Labview Front Panel. However, when I run it on "Windows Mobile 5.0 Pocket PC Device" (a PDA has been already connected to the PC), all the windows, menus, buttons are displayed correctly, the only thing wrong is that the waveform can't be shown in the Waveform Graph. So, I wonder whether the Windows Mobile system will automatically modify the binary file format a little when I copy them from the PC to my PDA so that the original VI can't process it as what I expected in PC execution. Or, are there any requirements for the programs that will be executed in actual Windows Mobile Device?
    Thanks a lot for any comments and suggestion. 

    Thanks, Jeremy,
    I used LabVIEW 8.5.1.  I rechecked and debugged the VI. The problem is not due to the Waveform Graph. I set an indicator after the Read File unit, in both PC Front Panel and PDA Front Panel. As I described before, when I run it in the PC Front Panel, the indicator could show the right values read from the file. But when I switch to PDA Device Front Panel, the indicator shows zero (invalid values), which demonstrate that the data is not accessed from original files.
    The units I used are shown as follows:
    File Dialog ---> Open/Create/Replace File ---> Get File Size ---> Read From Binary File (Here I set an indicator, no values read from the file, but if run in PC, correct values will be shown).
    In this case, I guess the problem should come from the transfer (copy operation) of the file from PC to PDA. Or the operation behavior for LabVIEW  Read File unit is a little different for PDA implementation from its PC implementation.
    If you want more information, including the original binary file or VI, please let me know. Thanks a lot.

  • Do I need to use DAQmx Base for PDA module or DAQmx will work just fine?

    Hi All,
    Does PDA module work only with DAQmx Base or DAQmx as well?
    hellolv

    Hi hellolv,
    The PDA module currently only works with DAQmx Base.  If you've never used DAQmx Base before, it is actually very similar to DAQmx, and there are lots of examples out there to get you started.  I recommend searching through our Example Code Library.

  • PDA module question

    I just got my PDA module and try to write a simple program run on emulator. But after I click the icon in the emulator. It show "connecting to LabVIEW" and stay there forever. why?
    also, after I switch target to my PPC, I can not find the icon in my PPC. why?

    Hi:
    How about your PDA module? Does it work well? Is there any bug for it? Can it commmunicate with PDA? Is the file to download big or not? Can it run well on PDA?
    Thanks

  • Can any one implement Discrete wavelet transform in PDA module

    the attached vi does denoising based on dwt of waveform it works perfectly on computer but it shows some error when I try to run it as a pda module as I have used a dwt block from signal processing toolkit,could anyone suggest a solution or any other alternative it uses a text file..as input.

    I could add a low pass filter IIR to my data but the pourpose of this excersice is to use of the DWT to exactract useful information about a signal, e.g. feature extraction. What I also want to do is take one of the peaks observed at the coefficients and map it back to the original signal's time domain.
