"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.

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!

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 reports COREDLL.DLL error when using Call Library Function Node

I'm trying to build a LV PDA app that calls an external DLL file built using embedded visual C. When configuring the Call Library Function node I select the stub DLL, configure the I/O parameters and select OK. When the configuration dialog closes I get the following error:
LabVIEW: LabVIEW.exe - Unable to Locate Component
This application has failed to start because COREDLL.DLL was not found. Re-installing the application may fix this problem.
I do not get this error when using the configuration dialog in the example VIs.
Any suggestions as to the cause and/or the solution?
Thanks,
Ryan

Hello -
When you create a PDA VI that calls a DLL, you must include the .c or .lib file that corresponds to the DLL. Take a look at these documents:

Can Labview PDA provide multi-interface?

Hi:
I want to use labview PDA module to develop software. But I found that labview can't provide multi-interface design.
I don't have the Labview Module and I just think about it. So if you have any idea to implement multi-interface design, please give me some suggestion.
By the way, labview doesn't provide the menu control to implement it. So how to design menu in the interface?
Thanks,

I am not sure what you mean my multi-interface, so I may not answer your question. The pda module has a special block that allows shields part of the VI from compiling in the PDA toolkit. It looks a lot like the case structure. The idea is that pocket pc and palm have different funtions, so it is silly to have two different VIs when all you need to change is a single subVI so that the VI can be compiled to run for one platform and it can be compiled again without changes to run on the other platform.
To access LabVIEW's menu options for a regular VI, goto edit >> run-time menu. There are several shipping examples too. Goto help >> find examples >> click on the search tab and look for menu .

Labview PDA toolkit activation code

Hello,
I'm trying to activate the licence for the labview pda (for palm) toolkit.
In spite of the S/N is correct, i can t get an activation code. I get a
Developper Suite licence. I called NI support, even with my computer ID and
my S/N, they didn't managed to give me a valid activation code (eventhough
they checked the SN is a valid Developper Suite one).
The NI licence manager always tell me my SN is not the one for the product i
try to activate.
Any ideas?
Thx.
Olivier

I don't think any of the Developer Suites come with the PDA module. So the serial number for your Developer Suite will not work with the PDA module to activate it.
You should have received a separate serial number with the PDA module when you purchased it. That is the only one that will work to activate it.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.

Anyone worked on LabVIEW PDA module for Pocket PC?

LabVIEW 7.1 PDA Module is claimed having the new features:
* DMM support for helps you build portable instruments using a PDA
* Tab controls, graph zoom, and additional control customization improve development of professional applications for PDAs
Does anyone has any working example for the ZOOM and for DMM4050? The NI website's example for DMM does not work for LabVIEW 7.1 PDA Module.

Installing the driver for the NI PCMCIA-4050 is a little more complicated than other installations. You will have to follow the exact procedure stated in the "NI 4050 for PDA Readme.htm" file. I pasted the important information here:
Installing PDA files:
Place nirlpdriver.dll and NI4050DLL.dll in the \Windows directory
Place the NIRLP 4050.exe in the \Windows\Start Menu directory
Installing LabVIEW support:
Copy the LabVIEW\NI4050 folder into the C:\Program Files\National Instruments\LabVIEW 7.1\vi.lib\PDA folder
Copy the ni4050.mnu file into the C:\Program Files\National Instruments\LabVIEW 7.1\user.lib folder
Installing LabVIEW examples:
Copy the LabVIEW\Examples\NI4050 folder into C:\Program Files\National Instruments\LabVIEW 7.1\examples\PDA
Getting Started
Before the NI-4050 will be recognized by the PDA, you must run the NIRLP 4050.exe. This EXE will install the registries needed by the PDA to recognize the hardware as well as a test routine which allows you to verify that the device is properly installed.
Once the device has been tested, you are ready to begin building your own LabVIEW PDA application with the NI-4050.
If you are new to developing PDA applications with LabVIEW, read the LabVIEW PDA Module User Manual.pdf for getting started. You can find the manual by going to Start>>Program Files>>National Instruments>>LabVIEW 7.1>>Module Documents>>LabVIEW PDA Module User Manual.
There are several examples which come with the NI4050 for PDA. You can find these examples in the C:\Program Files\National Instruments\LabVIEW 7.1\examples\PDA\NI4050 directory.
When building code for your PDA which includes the NI4050, make sure to manually add the NI4050DLL.lib file in the LabVIEW 7.1\vi.lib\PDA\NI4050\Include directory. To do this, in LabVIEW go to Tools>>Build for PDA and then select the “Source Files” tab, press the Add File button and browse to the NI4050DLL.lib file.
Without these actions, your application will not work. Make sure that you install the NI PCMCIA-4050 driver AFTER an optional NI-DAQmx Base install.
Please let me know if you are still having issues after following all the directions from the readme-file.

I am trying to use Labview and RP1210 compliant hardware to connect to a truck J1939 bus and receive messages.

I am trying to use Labview and RP1210 compliant hardware to connect to a truck J1939 bus and receive messages.
Specifically I am attempting to read data frames using the RP1210_READMESSAGE . am able to configure the hardware and send a message to the J1939 bus. . I think I have not configured something correctly. I can use the RP1210_SENDMESSAGE and see the message I have sent on the bus using CANalyzer When I use the RP1210_READMESSAGE I get the timestamp from a message and the return from the function sends back the correct number of bytes (the number matches the number of bytes I sent out plus four bytes from the timestamp). What I am having trouble with is actually receiving the data. I have had the same type of behavior from two different hardware (Vector CANcase XL and Nexiq USB Link), so I don't think the issue is vendor specific.
Has anyone been able to make the RP1210_RECIEVEMESSAGE function work correctly?
Thanks for any help

Thanks
I have already tried that. The links are the NI RP1210 wraper. The problem I am having is using labview to interface with the RP1210 layer. The RecieveMessage char*fpchAPIMessage this is the output which is a pointer to a cahracter array. In this variable I can receive the timestamp of the message but not the message. The retun showns the correct amount of bytes are aviaable (18 for a 8 byte message) but I can only get the 4 byte timestamp I think I have to dereference this pointer to view the data. I am not sure how to fix this.

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,

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

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!
