LabVIEW Base version..

Is it possible to use signal processing VIs like FFT, windowing, filters and others under LabVIEW 2009 base version..
Thanks in advance,
Sriram N

No, they are not available under the base version. I would recommend searching on ni.com for those VIs and choosing the 'Online Help' option on the left. The title of whatever shows up should tell you what's not available in what version

Simulate event structure in LabVIEW base?

I have a LabVIEW base version (v8.6) which does not have the event structure. I found it was quite inconvenient to monitor the status of several controls (the action after click a control depends on the status of other control(s)). Especially if I want to add another function (control), the effort increase exponentially with the existing number of controls
I got an idea of simulate the event structure using 'Shift Register'. First, I will bundle all the values of controls into a cluster. Then I will put the cluster in a while loop, and compare the value of the cluster with its previous value (xor the shift register). If the compare result is false (none of the control is changed), the program goes to next iteration. If the XOR result is true (one of the control was changed), then the program goes into event handling code (it will pass which control has changed, and the whole cluster). So for each control change, we can write a independent code to process the event. After processed the event, the event was cleared.
The following is a section of my ugly code currently used to monitor several controls. And I am thinking of rewrite it using above idea so that there will be less likely a hiden bug.
Any comments of suggestions?

Altough this is an interseting academic question, we really can't duplicate the efficiency of the Event structure so springing for an upgrade is highly recomeneded.
But I am not here to sell LV but rather help LV developers so...
Start by developing an Action Engine with the following actions.
1) Init -caches control ref for all controls and indicators for which you need an event. Optionally rest them and cache their state.
2) Check - Will compare the current state with the prvious state and any changes get pushed onto a stack in the AE and if there are elements in the stack (due a change detected now or one left over form the last check) and returns a type-def'd enum describing what changed. Multiple changes should be on the stack for next time.
3) Get New - will return the new value of the value requested via an Enum.
In you top level VI use the AE to Init before you run and then use an "Check" method to se if anything changed. If it flags a change (boolean output of AE) then the Enum is used to select the proper case of a case structure. Inside the psuedo-Event case, you can use teh AE with the "Get New" action and pass the enum to choose which value to get.
It is hardly an Event Structure but it should come close.
Ben
But after looking at Knickerbocker's* post we can go farther.
Put the above code in a sub-VI that feeds a queue. Then you can monitor the queue for updates just like in an event structure AN you can queue up all of the changes at once and can ingore my mention of caching the change methods in the AE. Just let the queue handle the stack.

*Kudos for inspiration!

Low pass filter in LabVIEW Base Development System

Hello,
I've got a problem for several days and I haven't find even a hint to fix it so it's driving me crazy.
I'm developing an application on LabVIEW Base Development System for automatical aquisition and exploitation of five signals.
These signals are generated by a deformation gauge and four potentiometers linked to a NI USB 6210.
I'm using the DAQ assistant on LabVIEW to get and use these signals.
My problem is that I need a 2nd order low pass filter on the deformation gauge signal to get something I can use afterward and none is include in the Base development Sytem of LabVIEW.
I'm sure there is a way to pass through this without buying the Full Development version but I haven't found it yet.
Does anybody has already had this problem and succeed in fixing it ?
If yes, can I have the code ?
Thanks

Thanks for your responses.
I've tried to create a subVI using the transfer function of the filter I need.
Here is the diagram of this subVI :
I'm not sure of this transfer function at all. It seems too simple to me.
Does it look weird to you or does a low-pass second order filter can have such a simple transfer function ?
I've tried it and my signal is still unstable. I guess I'm doing something wrong, but as I'm not that good in electronics, I can't figure out what.
Thanks again

thanks for all..

Here is a decent list of the differences between the versions of LabVIEW. Since you want to create executables, you will need to add the Application Builder. If you find there are other functions that you may need, I would just bump up to the Professional version.

NI LabVIEW Base Development System for Windows and NI CVS-1454

I have NI CVS-1454 and NI LabVIEW Base Development System for Windows (LabVIEW 8.5, no LabVIEW Real-Time Module and Vision Development Module). How can I build a LabView-program and run it on my CVS-1454?

Hi Kirill,
In order to use your CVS-1454 you will need to buy the LabVIEW Real-Time Module and Vision Development Module as these features are not supported in your version of LabVIEW.

Questions on FND Diagnostics in 11.5.10 Base version

Hi,
We have 2 instances. One is 11.5.10 base version and the other is 11.5.10 CU3.
Doing, Diagnostics > Show Log on Screen > Statement (1) , is fine in CU3.
However, when I do that in 11.5.10 BASE I am not getting the debug messages like,
oadbtransactionimpl.writeDiagnostics(this, "start validate", 2);
I get the following which proves logging is on
"Warning - Low-level logging is currently enabled. Your application will not perform as well while Low-level logging is on."
I am seeing some logging information at the button pages.
But I don't see anything under

Data base version for OA 11.5.10 CU2

Hi,
which data base versions are compatible with ORACLE APPLICATIONS 11.5.10 CU2 ?
Many thanks.

Hi
The version you are using is certified. However, in the Spring of 2006 Oracle certified 11i to use the Sun Java instead of JInitiator. Please take a look at this posting for more information: http://blogs.oracle.com/schan/2006/04/18#a23
You may want to give this some consideration, particularly if you intend to use Discoverer as well. This posting may well help in that respect: http://blogs.oracle.com/schan/newsItems/departments/businessIntelligence/2006/10/31

How to download older base versions of iMovie?

I have a desktop mac version 10.7.4 with Mountain Lion. It didn't come with iMovie installed, which I found out is a new thing. The newest version of iMovie (11) costs $15, but my computer won't support it without Mavericks.
I no longer care if I have to spend money to buy iMovie. I was able to find, with my developer account, a way to download update 9.09. My mac supports iMovie 9 and anything before it. However, the update is not the base version. I need to find the actual iMovie 9 BASE VERSION.
Let me know how I can get any form of iMovie on my computer.

Where did you buy your Mac? All new Macs come with iMovie assuming you're buying from Apple or an authorized retailer.
If you bought from a third party can you contact them and try to get the original DVDs that came with the Mac? They will contain iMovie.
If that doesn't work you can still buy iLife '11 on sites like Amazon.

LabVIEW with version control

Hi,
      I am using LabVIEW with version control and only want to check out the VI which I need to modify. If I changed a subVI all the VIs directly or indrectly called this VI got recompiled and in order to save them I need to check out all the VIs are affected. If I only check out the file I need to modify and ignore other recompiled VIs the problem is if I use typedef ENUM and I still want the automatically updated VI got saved. Does anybody run into this problem?
    Thanks for help!
    Regards,
    Tom

Yes, it can be a problem since LabVIEW stores the source and compiled code in the same file. There is an option to separate source from compiled code that addresses this problem. I have never used it and don't know if it causes any other problems.

Event Driven Programming is withheld from LabVIEW Base.

Can anyone give me a good answer why? Every other programming language in the world has Event Driven Programming (EDP) built in, even free languages. So when all I wanted was to use LV as a graphical programming language, (hey, that's what the "G" in G-programming stands for) I was disappointed to find that in my undervalued LV Base I can't look for mouse movement, mouse enter, mouse leave, keyboard actions and countless other possibilities that would be standard fare in any other language, unless, I pay over 1200 dollars more for the Full development package. I know I should have read up on it more before purchasing, and understood what I would be missing out on. But how was I to know that the fundamental programming function of EDP would be considered on par with Data Acquisition and Signal Processing? So basically in order to get a complete programming language, I need to spend more than twice the cost of the Base package just to receive the last key component. And all this because the Evaluation of LV gives you near limitless possibilities, so a new LV programmer gets used to having these tools at his/her disposal, only to yank some of the most critical tools. So after saying all this, I am pleading for an explanation. Why isn't there at least some add-on module that would allow a user to install the withheld functionality of EDP to a Base Development package? Surely making money is the goal of any business, and I won't claim bait and switch here, or any other wrong doing here. But there is, in my opinion, a marketing misjudgment here.
-Orion Williams

Unfortunately to upgrade, it would cost me the difference between the base version and the full version. What I think is in order is an add-on module that will give customers the functionality of EDP, without having to also pay for signal processing, which is clearly a more robust programming tool, that I don't need. I am hoping to show NI that by withholding EDP from the base version with no upgrade option except paying for the full version, that their customers who come into LV at the base version are getting an undervalued version, and they know it, and that without at the very least, and add-on module for EDP, isolating smaller business and individuals. I agree that signal processing, data acquisition and EDP are worth an extra 1300 dollars, but I don't agree that EDP on it's own is worth an extra 1300 dollars, but that's the only option that I have at this moment. My suggestion is to create an add-on module that includes EDP and sell it for 300 dollars, since I know signal processing is a much more complex feature and is worth more of that upgrade price than EDP. Of course all versions of LV should include EDP, so if that drives the price of LV base up, so be it. Just don't let anyone else be fooled into thinking they are buying a Graphical Programming Language unless all the features of a programming language are included at all price points. Can I get a witness?

I have several macs with Intel core duo 2 operating systems. All are running os x10.6.8. Is it necessary to upgrade to Lion before upgrading to mountain lion when it comes out this summer? Do I need to have the "base" version of 10.7?

This is unknown, it will be up to Apple and AFAIK they haven't announced that yet.

Data base from Labview Base, possible?

I would like to sent my generated testreport(.txt) into a database. So that every report from every test is stored in a Data Base.
Is this possible with LabView Base 7.1 or do I have to buy Developer suite?
How do you do this?

There is an example VI which

No additional tookits would be required.

Help if you can.

Hello RBrown
I am really sorry for this inconvenience! This is a known issue.
Can you please attempt the following for me:
When you are building an application, under Advanced please check the last box "Use LabVIEW 8.x file layout"
If that doesn't work, you may need to rebuild the LLB in a separate directory with new names, and use it as the build inclusion.
Here are some forum posts strictly for your information:

Is it possible to download the LV code to pda in LabVIEW evaluation version?

Is it possible to download the LabVIEW code to pda in LabVIEW evaluation version?
For example:
I want to select New » Targets and Devices from the shortcut menu to open the Add Targets and Devices dialog box as shown in the below Figures.
Is it possible to do the same in evaluation version of LabVIEW 8.0

Prasada,
In order to target a PDA device, you will need to have the PDA module installed. Fortunately we do have evaluation software also available for the LabVIEW PDA Module 8.2. Once this has been installed, you should be able to target your PDA device. Please post back if you experience any trouble. Thanks,
