Anyone worked on LabVIEW PDA module for Pocket PC?

[yqin]

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.

Remember that any NI 4050 example needs you to install the driver for the VIs to work. Install the driver from here:

NI PCMCIA-4050 Driver for LabVIEW PDA

There is an example available that includes both the zooming functionality and the NI 4050 connection here:

Bluetooth Enabled DMM with LV PDA

Are you having issues with this example? Please let me know what you mean by "...does not work...", thanks.

Good luck!

Do you try this?

I have try this before and it would NOT work. I have sent the request for support 3 weeks ago and was told they are still working on it.

I will look further into this and get back to you...

I have checked the example and it does work on my PocketPC 2003 PDA.

In case you want the NI-DAQmx Base driver installed on your PDA, it is important that you install that driver before you install the NI PCMCIA-4050 driver.

Let me know what doesn't work when you follow the instructions of this tutorial:

Build a Bluetooth Enabled PDA Digital Multimeter with LabVIEW PDA

Philip,

I just receive the reply from Andrew Akers, the following is the reply:

*********************
The example will not work with LabVIEW 7.1.

You need LabVIEW 7.0 with the LabVIEW 7.0 PDA module, and a PDA running the Pocket PC 2002 operating system.

This is the only system on which you will be able to run the example.

I feel confused because your answer is different from him. Could you confirm this with Andrew Akers?

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 did EXACTLY as what you said. SAME problem. In fact, I did this exactly as what the NI 4050 for PDA Readme.htm told me to do.
