LabVIEW PDA

Hi! Everyone
I have to develope an application for PDA in LabVIEW. Can someone tell me how and where to start....the interface is with RS485. The PDA needs to scan for attached devices and report devices available.
There are some parameters to be acquired
and data to be displayed.
I am not sure if it is a palm or pocket pc. If I start with the development of the Vis on LV Express, do I need to know the OS before hand....will that affect the VIs?
Can I use LV express base package to develop the VIs or do I need LV PDA toolkit for the development?
And if once I have deployed the program on the PDA, can I run it in debug mode and can I delete the program from the PDA or not?
If there are link which I could go through or programs to be taken as the star
ting point...will be appreciated.
Thanks!!

You Could develop your applications using LV express. The only problem is that all the features are not supported on the Palm or the PDA. You also need to know before hand as to what your execution target is as LAbview has a Palm module and a PDA module that are sold seperately. The link below has the PDA manual.

You could also look up the knowledge base for specifics for the PDA and Palm.
You can delete the program from the PDA. There are some example code and documentation at

    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!

  • Accessing mySQL database from Labview PDA

    Hi,
    Has anyone tried writing data to a mySQL database or any other database for that matter using the Labview PDA module?  I know it's easy to do from Labview and you have to download the ODBC drivers to get it working but I don't think these drivers are available for Windows Mobile (I've seen XP and Linux drivers only).  Any help would be appreciated.
    Thanks

    Hello,
    I don't have experience with this, but you might look into the following:
    1. remote connections: http://www.geekzone.co.nz/content.asp?contentid=2656
    2. this thread seems to indicate .NET doesn't support it yet (but it's over a year old...): http://forums.mysql.com/read.php?38,73109,73109
    3. Another option - you can use VI Server to have your PDA VI call a VI on your host machine if they are networked... there is an example of this that ships with LabVIEW PDA I think - check it out!  Thus, if the db is on your host machine, you could write your host VI, and have your PDA VI call it etc.
    I hope this helps!

  • LabView PDA module gives error "unable to lock memory chunk"

    I've written a LabVIEW PDA Application that reads an ASCII decimal string through a PDA serial port. I can display the string ok, but when I try to convert the string to a number using the decimal string to number VI I get the error message "App failed. Error Code 172649003. Unable to lock memory chunk."
    Any ideas?
    Cheers, Paul

    Does this happen whenever you use the string to number VI (can you reproduce this in an empty VI)?
    Are you sure it happened because of that VI and not because of something else that is happening in the VI at the same time?
    Can you cut down pieces of the code and still get the error? Can you post a small example?
    Which PDA\LV are you using?
    Can you write some more details about your app (does it do anything else other than serial comm)?

  • Winsockread Error in LabVIEW PDA

    Hi all. I am currently trying out the VI server example given in the LabVIEW PDA toolkit but i keep getting this error "WinsockRead error Error Code: 10054.
    The LabVIEW example project I am using is "VI Server- Pocket PC.lvproj" and I have loaded the "CallByRef Wave - Pocket PC.vi"  into the PDA. I have a WIFI connection to a PC and have manually assigned IP address to both the PDA (192.168.100.101) and PC (192.168.100.100). I have verified my WIFI connection is working by using the "ping 192.168.100.101" command on my PC.
    Also, I am configured my VI server correctly by selecting the enabling the TCP/IP protocol and ActiveX under the VI Server Configuration. The port number I used is 3363. I have also added the PDA IP address (192.168.100.101) to the Machine Access List.
    When I try to run the example program on the PDA with the IP address "192.168.100.100" and a port number of 3363, I will get the error. Can anyone give advice on what I have missed out or done wrongly?
    I forgot to mention that the remote program "TargetWave.vi" on the PC is loaded in memory and opened in LabVIEW also.
    Thanks in advance.

    D.Com,
    I just thought of something else to try. You said you are using port 3363. The program was initially set up to use Port 3865. Did you change the VI server properties (From the project, right click on the my computer icon>>properties>>VI server: Configuration) to port 3363 or just the control on the front panel of the CallByRef Wave.vi? Both must be set to the same port.
    Secondly, you may have to open a port in your firewall if you are using WindowsXP SP2. Initially I would completely disable the firewall and see if that solves the problem. If it does, then enable the firewall and create an exception of the port you've specified (3363).
    As for using the trial version, this should have no impact on the performance of the toolkit.

  • Queries about LabVIEW PDA

    I have a problem with displaying measurment file on the waveform graph in the PDA. I understand that PDA have some function constraints and does not support "Read from measurment file"function. Is there any way to convert the measurment file to a file which the PDA waveform graph able tom display the result or should i replace the "write to measurment file" function to other function e.g write to spreadsheet? How do I include the header,time and date in a spreadsheet heading?

    It would probably be best to originally write your data in a tab-delimited format (including labels, time stamps, etc). Then, you can program the Read from Text File function in LabVIEW PDA to mimic the behavior of the Read from Spreadsheet File VI in LabVIEW.
    Once you place the Open/Create/Replace File and Read from Text File VIs on your block diagram, you can write click on the Read from Text File VI and select the Read Lines option. Next, scan through each line for tab characters using the Scan String for Tokens VI, and finally build up a 2D array of all elements in your text file. This may sound a bit confusing, so I have attached a small example VI to this post below (PDAReadFromTextFile.vi). Don't forget to use the Close File VI when you are done reading from disk.
    Keep in mind that PDAs do not support array indicators, so you must view any front panel data as individual strings (or one large concatenated string). The Index Array function on the Array palette should come in handy here.
    I hope this helps!

  • 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.

    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

  • LABVIEW PDA/DAQmx Base error

    I'm building a VI for a PDA (pocketPC 2003)
    In a Functions Panel, when I'm going in a menu "Measurement I/O" => "DAQmx Base", it misses many icons. I have installed and uninstalled three time DaqmxBase 2.2 with the same result (icon.jpg). I have installed Daqmx Base 3.0 and the problem is always there. Moreover, when I'm going in menu "Select VI" in a Functions Panels, I can open anothers Daqmx Base VI, but there is many errors (error.jpg).

    Hi,
    LabVIEW PDA support for DAQ is limited.  The number of DAQ VI's available on LabVIEW PDA is also limited. 
    I could not clearly view your error list but I did run across a possibly useful Knowledge Base article. I am also including the Known Issues with LabVIEW PDA 8.2.1 . I hope this helps!

  • Labview PDA support USB?

    Does the LabVIEW 8.0 PDA support USB communication?

    optomesures,
    I have seen a regional option have this effect before.  I would check to see if you are using a period or a comma for the decimal point.  You might want to try following the steps in this KB to see if that helps.  If not then I might suggest checking out the Calling External Code in LabVIEW PDA KB as well.  One last thing to try would be to see if the code works on the Windows machine.  The DLL would have some problems, but make sure it is has at least a basic functionality.
    Hope this helps!

  • LabVIEW PDA customize boolean control with picture

    For a PDA application, I'm looking for a way to customize a boolean indicator. To do this I went in the customize option of the boolean and then import picture for the false and true state. in programming mode I see the correct picture for the different states but when I download this application on my PDA (TPC-2006 with winCE) in only see a blank picture on the boolean. Is this a limitation of the LabVIEW PDA or is there another way to do this ?  (see example in attachement)
    Thanks in advance for your help.

    Hey Poussin,
    You bumped into a boundry of LabVIEW PDA. LabVIEW PDA did not support custom controls at all uptil very recently. Only since LV PDA 7.1 there are a few features which are possible like coloring and resizing, see the link below.
    http://digital.ni.com/public.nsf/websearch/08DD9CAACA1F64F586256E920061E4CD?OpenDocument
    Using pictures however is not possible. The control will have its functionality on the PDA but it will not show its decoration.

  • Labview PDA using RS232

    Many new PDAs have USB cradles only. Can someone recommend a good configuration (PDA, OS and any options) that worked for Labview PDA to control instrument through RS232?

    I don't have a lot of experience with various PDA models but I'm using a Palm OS Tungsten T5 to do serial communication. I did have to buy a cable that converts the TTL level RS232 to as "true" RS232 level. Once I got that it worked rather well. As far as I know most Palm PDAs have RS232 coming out of there sync connector. You just have to do some digging or call the manufacturer to get the right info.

  • "LabVIEW PDA - Palm OS Hardware?"

    I'd like to get some feedback on what Palm OS PDA's are being used in conjunction with the LabVIEW PDA software. I've been tasked with creating a very compact application for monitoring a system, and we're interested in doing this through a Palm PDA (I chose Palm simply because I used to write Palm applications a few years ago, and I'm pretty familiar with their system). We have a DAQCard-6062E that is used in a laptop at the moment, but for this application, that's just overkill. I'd like any input from users on the following:
    1. What type of Palm PDA (model number) are you using with the LabVIEW PDA software?
    2. What type of cradle (model number, etc.) that goes with the Palm PDA for a PCMCIA card? Also, where can you get this cradle?
    3. Interface cable preferences? (length, type, etc.)
    Thanks for your input,
    tsc

    Hello –
    Palm M-series or Tungsten supports a DAQ device. CEC sells these DAQ devices with a sleeve and you just have to put the Palm device on it. Also, they will provide you with a driver that will allow you to communicate with LabVIEW PDA for Palm.
    Go to this link. Click on Data Acquisition, then on pdaDAQ/100.
    Hope this helps.

  • Labview pda 8

    Is there a PDA version 8 out? if not how well does Labview 8 work with Labview PDA 7.1?   

    LabVIEW 8 for PDA should be released in the next few weeks. right now,
    the only "8" version products that have been released are LabVIEW and
    DAQmx. The rest are on the way.
    The 7.1 PDA module will not work with LabVIEW 8.
    Unfortuately, we have to patient and wait. I'm waiting for RT, FieldPoint and FPGA myself.

  • LabView PDA and Pocket PC2003

    I am using Pocket PC 2003 with the LabView PDA.All the documentation deals with Pocket PC 2002. Are there any changes with the Pocket PC 2003? Also I wrote a test application and downloaded to the PDA and that does not seem to execute!Is it bcos of the 2003?
    Thanks

    I have exactly the same question. I have LabView PDA 7.0 and a Pocket PC 2003, VIs run ok on Pocket PC 2003 but the problem is when I try to run VIs that call DLLs. The ones that work perfect in Pocket PC 2002 don't work in pocket PC 2003.The DLLs were created using EVC 4.0 SP3.
    Are these incompatible?

  • Labview PDa 8.0.1 can support visa

    hi all , can u plz tell me Labview pda 8.0.1 can support modbus serial communication

    Unfortunately, you cannot do modbus serial communication with LabVIEW PDA 8.0.1. In oder to do Modbus communication you would need the Modbus Library, but that requires NI-VISA and NI-VISA is not supported in LabVIEW PDA until version 8.2. Aside from this, you can do regural serial communication with PDA 8.0.1 using the Serial Compatibility VI's.
    For more information please refer to the following knowledgeBase articles:
