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

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...

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

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
Greycat

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.

Student version pda module?

Hello!
I have got the Labview 8.0 Student Version and I am very happy with it. I think it is a great Programme and I am learning it right now.
I want to create programmes for my mobile phone, which has windows mobile 5.0 installed.
What software do I need to create such programmes. I have found the PDA-module for Labview, but this is very expensive and I can not afford this as a student.
So my question is: Is there a student version of this module available, a demo version or a limited test-version?
Sorry for my bad english, I am from germany.
Thanks for your help!
Greetings, Felix

The LabVIEW 8.0 Student edition software suite includes 5 toolkits and apparently does not include the PDA module.
See: http://www.ni.com/labviewse/select.htm
If I remember correctly, the LabVIEW 7.1 Student edition suite included 12 toolkits and I think the PDA module was one of them. Have a look at the 7.1 Student edition readme: http://www.ni.com/pdf/manuals/374075a.pdf
Maybe it is still for sale somewhere?

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 dynamically in an application?

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
thats it

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.

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?

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.

"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.

will this helps you? if didn't solved your problem, post back.
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.
Attachments:
Mobile Portrait11 (1).vi ‏72 KB

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.

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.

Upgraded to 8.2.1 now I have a version mismatch for the PDA module ver. 8.2

I just recieved a new laptop. I installed LV 8.2.1, then PDA module 8.2. Programs will not build. I get a "Mismatched Versions of Labview and the PDA module" error. Help.

Hello,
I was able to reproduce this version mismatch error on a test PC with LabVIEW 8.2.1 and PDA 8.2. This is expected behavior. Also, Matt called in on the phone, and I directed him to his internal sales representative to be shipped 8.2.1 of the PDA module.
I suspect the reason why I was not encountering this on my own PC was that I had already upgraded my LabVIEW Touch Panel Module to 8.2.1 but not PDA yet.
For all people reading this, the ultimate answer is that the PDA version number should match the LabVIEW version number.
