Peak hold function in LabVIEW

Hi,
I have a filtered signal in which I need to get the values of all my peaks (positive and negatives) and afterwards get the mean value. Some oscilloscopes have this function implemented, but I haven't found such a subVI in LabVIEW. Is there any chance to get this function or I have to program it? In this case, I've thought using the derivates of the signal and compare the values and check the derivate tendence, but I think that this function will made my process very slow. Any ideas?
Thanks in advance,
Angel

Just by doing a quick search on the functions pallete I found two VI's that should do what you want. the is a mean.vi and a peak hold vi. I do not know if you have already found them and they will not work or if you could not find them. these VI's may not be avaiable if you have the base package.
I Use labview 7.0 (full)
Joe.

Sound and Vibration kit - Peak Hold

I am evaluating a dynamic signal and would like to gather peak hold information from SVT 1/3 octave output. The SVT FFT tool has a "peak hold" function that allows for gathering spectral data over time, but it does not output an array of values. Is there a way I can capture peak hold from the SVT 1/3 octave output and create an indexed array that integrates a dynamic signal in a "peak hold" manner?

Hello mstocker,
From your post this is what I understand:
You want to perform peak hold averaging with your Third-Octave
Analysis.vi and then obtain an array of data of the peak values. The
Third-Octave Analysis.vi has a selection for the averaging type you can
select peak averaging as the type of averaging. Peak averaging combines
the results of several measurements into one final measurement. The
output of the Third-Octave Analysis.vi is a cluster. The cluster
contains one array of nominal frequencies and an array of band power.
Is this what you were looking for?
If I have misunderstood your post, please reply with clarification. I would really appreciate it.

Does anyone know why the waveform peak detect function provides accurately the position of the peaks but not the value?

Does anyone know why the waveform peak detect function provides accurately the position of the peaks but not the value?
I have been looking at my data at the position indicated by the function as a peak, and it is correct at that place the wave has its peak, but the value provided by the function is higher than the actual value at that point.

The help makes it clear that the VI will make a quadratic fit to the data, so the locations are not integers (i.e. not aligned with you exact data). From that analysis, the peak is between two of your points, and slightly above the neighboring data.
See the coercion dot. Make the "locations" array DBL (Why did you change it to I64, that makes no sense at all!)
Quote from the help:
"Locations contains the index locations of all peaks or valleys detected in the current block of data. Because the peak detection algorithm uses a quadratic fit to find the peaks, it actually interpolates between the data points. Therefore, the indexes are not integers. In other words, the peaks found are not necessarily actual points in the input data but may be at fractions of an index and at amplitudes not found in the input array."
All clear?

Register a Callback function in LabVIEW

Is there any way to register a callback function in LabVIEW. For example:
I have a DLL on Win2k that run a thread. This thread is doing a certain task (it is not important what it does...) I can't predict when this task will end and I need to know when the task is over. The easy way would be to poll this DLL and ask: "Is it over? Is it over?" over and over again. No! I don't want to poll. Not because it's too easy. I want this DLL to wake me up on time.
Any idea, solutions, function that I'm not aware of, new features...
Thanks
Nitrof

I think I have a much better solution for you. Here is an example program that show how to set a LabVIEW occurence in a dll. Therefore when your dll is done it can set the LabVIEW occurence, meanwhile your VI is just waiting on the occurence.
More infomration on this is in the external code in LabVIEW manual Using External Code in LabVIEW
NOTE:This will ONLY work in LabVIEW 7.

Different output of DST function in labview and matlab

I am passing a 1D array of size 1550 as input to DST function. I have also calculated DST of same array in matlab using 'dst' function. I got approximately same answer till 1399th element but after that answers of two varies abruptly. I tried hard but I am unable to find the solution. I am attaching the data file in which it can be clearly seen that at 1530th element there is a difference of sign also.

data file1.txt ‏37 KB

Out of curiosity, have you tried another software, like Octave? When you have two software that is different, which one is incorrect?
Also, have you tried to use the DST function in LabVIEW directly?
Another think to keep in mind... When you try to run a sequence for so long, small round-off errors could be cummulative and show later on the analysis. Also, it depends on how you load the data into each software. Hopefully when moving the platforms, the string conversion would not truncate the number. The best is not using string, but some kind of binary format...
These are some ideas to check...

Functions in labview

Hy,
I've got a question concerning functions in Labview.
Is it possible to see the *source* of a function ?

Thanks a lor for the info.
So there is no way to get the algorithm directly from labview?

I am trying to call a function with LABVIEW developed in CCS compiler

I used MPLAB (CCS compiler) to develop c code that is used to transmit and receive messages to and from an automotive display. It works great as a stand alone. I would like to call this function from LABVIEW but am having difficulty doing so. Does anyone have experience calling a MPLAB developed project from LABVIEW? Thanks in advance.

MPLab is for programming PICs if I'm not mistaken. I'm not sure how you would want to call a function compiled in MPLab from LabVIEW directly. MPLab will create binary code for execution on PICs and there is no LabVIEW that could run on a PIC. On the other hand I didn't think you could create standard Windows DLLs, Mac shared libraries or similar in MPLab at all.
You will have to recompile your code in a C compiler that can create the standard shared library format for the plaform you want to call it from LabVIEW.

Can i call winmain function in labview

hello everyone,
Well i have written a C++ code that uses the winmain function (windows function). i want to convert this code into dll and call that dll into labview.
Is it possible to call winmain function as one of the functions in labview. Please let me know as soon as possible.
Thank you.
Royal tiger......

You didn't say what development environment you're using, so I'm assuming Visual Studio. It sounds like you created a Win32 app (as opposed to an MFC app). This has a "WinMain" function. The prototype for WinMain is geared towards it being called by the OS when you run the executable. You could just add the __declspec(export) directive in front of the return type, but you also need to change some build functions in Visual Studio to get a DLL. You probably also don't need all the arguments that WinMain uses. You're probably better off by starting with a new DLL project in order to get the framework for a DLL, and then copy and past the function code. That's what I would do.
I would also strongly suggest that you crack open the "Using External Code in LabVIEW" manual that gets installed when you installed LabVIEW. It's in the "manuals" directory, filename of "lvexcode.pdf".

"HOLD" functionality NOT working in Sourcing cockpit.

Gurus,
I have 2 issues:
1)
I am trying to hold requsitions in Sourcing cockpit but when I add them to Workarea and click " HOLD" button it doesn't do anything ( NO Messagee, Nothing) and when I check back in it still shows the requsition item in the scourcing cockpit not the hold status.
I think the Hold Functionality is not working properly...is thee any fix to it or any OSS Note.
2)
We are facing a issue with the Vendor Text being getting copied from a catalog item to a Free Form item while the creation of shopping cart.
When I am creating a SC - say with 3 line items with 3rd line item as Freeform item and 1st and 2nd as catalog items then the vendor text is getting copied from the Catalog line items in to the Freeform line item.
So if two catalog line items are there then Vendor text gets copied twice in the Freeform Line item.
Is there any OSS note or any fix for this
Kindly advice.

Hi,
1)
Please go through these SAP OSS Notes ->

Hope this helps.Also seems to be a bug in the system,so paralley raise an OSS message.

Problems of integrating Matlab functions in Labview

Hi,
Does anyone know how to completely integrate Matlab functions into Labview program without a copy of Matlab in the system when I run the entire program?
Initially I used 'Mathscrip' node but I heard that it doesn't support Matlab toolbox. Thus, I tried out the other option 'Matlab script' node. This node works well in implementing Matlab functions but it indeed requires Matlab installed in the system.
So in other words, how could I realize the full integration(as what Matlab script node achieves.) without Matlab installed in the system?
Cheers,
Nicholas

hi smercurio,
So you mean that the Matlab script is no longer necessary in my case right?
Could I just ask my colleague to compile his codes to matlab dll and I use the Call Library Function Node instead of Matlab script to call it?
About MCR, is it the correct source at the following link http://www.mathworks.com/matlabcentral/fileexchange/5268 ?
Sorry for those basic queries in Matlab as I have very little experience in it. lol... thanks a lot.
Cheers,
Nicholas

Vendor hold function

Hello,
our users work very often with the hold function in ME21N, because for new venndors we have a specific creating flow.
So the purchaser creats a PO without vendornumber and do hold.
The PO is correct in all points. The purchaser maintain the header text of PO also on a very detailed level. (2 pages is nessesary)
If the Vendor is created the purchaser put it in the PO. What happens?
All header texts are lost.
Is this normal that the header text are lost if i fill the vendor in a holded PO?
The same Behavior do we have on item level if we change the materialnumber.
Here we lost all item texts.(material-text i would unterstand)
Is this a normal Behavior or is there a possibility to manage this.

Where can i find the FFT functions in Labview 7.1 Express

Can anybody tell me where i can find the FFT functions in Labview 7.1 Express or what i have to install??
regards
Acosmo

Hello Acosmo,
You can find them under
All functions - Analyse - Signal processing - Frequency domain.
It's maybe easier if you do a search: when you right click on the block diagram, you have a seach option, just write there FFT and you will have them there.
Hope it helps,

Can not find size_t during import a dll and calling a function crash labview

Hello, experts
I need to use FingerLakeInstrument DLL ( see the attached) inside Labview to talk to a CCD camera. it is built from microsoft visual studio C++
I unzip FLI dll in my D:\proj\...\linfli-32 and import dll from there. created a c:\FLIDBG.txt as FLI dll needs to write debug message to it if FLISetDebugLevel() or others are called.
During importing the dll, first thing I got is <sys/types.h> ( ie size_t ) cannot be found. I have installed free version of microsoft visual studio C++
but can not find "typedef unsigned int size_t"
at the end, I just added
typedef unsigned int size_t;
in the libfli.h. Having done that, I am able to import all functions into Labview and have a user library called libfli.
However, as soon as I start calling a simple function in a test.vi, such as FLIGetLibVersion(char* ver, size_t len), which involves nothing other than the library, the labview will crash.
I created a simple C test.exe which calls many functions without any problem
any suggstion?

xiaofeng

libfli-32.zip ‏93 KB

Hi, Smercurio_fc
thanks for your reply. Yes, you are pointing to the right place. I have solved the crash problem.
when importing DLL into Labview using Tools\import\Shared Library (.dll), Labview automatically set the calling convention as C not as stdcall (WINAPI). it is this that later the labview crashes when a function is called. as soon as I manually re-selecte calling convention as stdcall, my test.vi works OK (see attached).
I tried Call Library Function too to call libfli.dll, as long as I select stdcall as call convetion. the test.vi works.
How do I know which Call convention I need to choose if there is no infomation from DLL provider?
as for the size_t,
I add #include <crtdefs.h> in libfli.h and
add additional include path as
C:\Program Files\Microsoft Visual Studio 10.0\VC\include. this solved the "not found" issue.
for this case I know that the DLL is built from VC++, is this right way?
again, thanks for your time.

MIGO use of the HOLD function

HI Experts
I have a requirement that the user will use a approval while posting MIGO.
f.e. the tolerance checks failes and MIGO doesn´t allow to post. This is the trigger to ask the next higher person for approval to allow a higher tolerance.
My Idea was to use the hold function.
I will use BADI MIGO_GR_CHECK (MB_MIGO_BADI) Method HOLD_DATA_SAVE.
But the problem is that I need the current information from MIGO (later MSEG/MKPF).
Do you know how to get the information?
The Paramter I can use in this method is just I_GUID.
I know there is a sample coding, but this doesn´t help.
Thanks
Alex
