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

[NyanLin]

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

Nyan,

I was able to replicate a VI similiar to your and deploy it on a Pocket PC 2003 PDA device (a Compaq iPAQ PDA); therefore, all your functions are able to be transferred over to a PDA. As far as arranging the waveform graphs I would recommend using a tab control, so that you are able to have each graph on a different tab (see attached screenshot).

Hopefully this points you in the right direction and let me know if you have any further questions related to this issue.

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

Nyan,

(1) Unfortunately, besides tab controls, there is no way to more efficiently use the limited screen space on the PDA. I would recommend expanded your graphs are large as possible by hiding the graph's plot legend and label (right click on graph and select Visible Items >> Label & Plot Legend).

(2) To delete the old application, I would recommend using a tool in Microsoft ActiveSync (on your PC) to browse to the executable on your PDA. If you bring up the ActiveSync dialog box you can explore the PDA file structure on your PC by going to Tools >> Explore Device. If you are unsure about where LabVIEW deploys the executable on to the PDA, you can check this by:

1. Going to your project explorer window in LabVIEW
2. Right click on the executable under the PDA's Build Specification and select Properties
3. In the dialog box that appears check what the PDA Destination Directory is

(3) The NI CF-6004 is a data acquisition device which allows the user to collect data through four analog inputs. It does not provide extra memory for your PDA.

I hope this helps and let me know if this answers your questions.
