  • How to create a DLL from a .mdl file model to use on veristand simulink

    Hi all

    I want to create a .dll file from a simulink model .mdl file. I created a simple "Sample.mdl" file that adds two entries and gives the result.

    Before you build the .dll, I tried to run file .mdl veristand. Here, I got the below error.

    Method 1: I tried to create a DLL out of it by going to the Simulation-> settings-> workshop in real-time. Here I tried to change the target file system to NIVeriStand.tlc, but I'm not able to see that in the system target file browser dialog box. Can anyone tell me the reason behind that.

     

    Then I tried method 2.

     

    Method 2: I created this .mdl C code using grt.tlc in the Simulation-> settings-> workshop in real-time. I clicked on 'build' button, then he created C equivalent for this code. Using Microsoft visual C++, I tried to generate the .dll file, but I have the following errors.

    Can someone help me on this please. My goal is to launch this model with veristand eithor in.dll or .mdl file format

  • can I create a DLL file for labview that has DLL library with inside?

    Hello everyone,

    I am developing an application for the cards PCI devicenet in labview (beginner to labview) environment.  Is there a DLL file for the PCI card from the provider. But it's too complicated for a beginner to call each function in the DLL of labview. Therefore, I'm trying to re - use a VC ++ program (working properly) that calls some sellers DLL library functions.    To do this, I created the DLL file which includes all headers and libraries the provider DLL, as indicated in the attached figure. But I couln can't see the effect on the device. is it possible to create a DLL file for labview that has DLL library with inside? If this is not the case, how can I implement the program shown in figure?

    I would like to wish a huge as to advance.

    It is not something I have a lot of experience in so I don't know all the details of the restrictions or requirements etc - but it is certainly possible to create wrappers for the dll and then use them in LabVIEW - this is sometimes necessary to convert some native types/data structures in C/C++ into something that you can switch to your other DLL LabVIEW.

  • Create a DLL to read an Image using OpenCV

    Hi all

    I am trying to create a DLL to perform image processing using OpenCV. In the first place, so I try to create a DLL that can read an image and display it. But I encountered a problem when I call this DLL in LabVIEW.

    The error in LabVIEW that says: "error 1097 appeared to call library function node in the .vi DLL Image playback (Play).

    Possible reasons:

    LabVIEW: An exception occurred in the external code that is called by a node call library feature. The exception may have damaged the memory of LabVIEW. Save all work to a new location and restart LabVIEW. »

    Here are the steps I followed:

    1. download OpenCV2.4.9 and extract the files. Make changes appropriate to the Environment Variables to include OpenCV.

    2 start a new 2010 Visual Studio from Microsoft Project to create a DLL.

    3. Add a property sheet in the property manager to include the OpenCV library.

    4 change the DLL of playback picture .cpp code (Play) as it is in the attachment.

    5 compile to create the DLL of playback picture .dll (Play) file.

    6 create a LabVIEW VI to call the DLL.

    Attached are the related files: 1 .cpp reading Image DLL (game) 2. Read Image .dll DLL (reading) 3. Read Image .vi DLL (game)

    If someone good to help me with this? I guess it might be the problem with the .cpp code DLL Image playback (Play).

    Thank you very much.

    1 joint code .cpp DLL Image playback (Play):

    include opencv necessary image processing libraries

    #include "stdafx.h".
    #include "opencv2/highgui/highgui.hpp".

  • creating event dll

    Hello

    I have create a warpper dll control ASIO drivers for sound cards. I want to generate an event on the buffer for LV switch can perform the necessary work.

    I finished a first version using a fast while loop in LV, but I think that generates an event is a very elegant solution.

    The problem I have now is to compile my code! Indeed, I found a few questions how to generate events of my dll. I get "extcode.h" and some other stuff from "C:\Program NIUninstaller Instruments\LabVIEW 8.5\cintools".

  • creating a dll from simulink model labview requires visual studio

    I don't use Visual c, few do what programming was made in Borland Builder or with gcc command line.  Is there a way to make simulink for a different dev environment?  Or this process requires Visual C?

    Hey,.

    It depends on what version of SIT you use.

    With SIT 5.0 and later versions you can use a free compiler as described here:

    http://digital.NI.com/public.nsf/allkb/AAD15283A1F051A1862574F000744DBD?OpenDocument

    With earlier versions, you need VS. 2006.

    Hope this helps,

  • LabVIEW created DLL that uses Labview live integrated Toolbox "DFD" (Digital Filter Design)

    We were using a Labview created the DLL file that uses the screws of the DFD Toolbox, but were not able to operate at all. Now, we have replaced the DFD screws with screws that built us, and the DLL file works fine. Is there a reason for this?

    Even if it works, this process is medium long and it's a waste of time because the DFD screws are already being implemented, so we need a quick fix for this, any suggestions.

    When you use the DLL that uses the DFD screws, it always seems to be a failure when loading the DLL file specific screws, anyone know why? Screw looking for Labview is in a way that looks at "DllFileLocation.dll------Labview 2009------vi.lib------...» "

  • LabVIEW can create DLLs 'returning '?

    Can LabVIEW create reentrant DLLs; I mean, there a dll that maintains state information between calls? If so, how are you implementing it?

    Thank you

    Maintain state information can be done through a registry to offset the.  This also works in a LabVIEW DLL.

    Make sure that the DLL is not unloaded between the function of other calls he will lose his memory.

  • DLL and global variables

    OK, here's a strange problem.  I am very new to create the dll, so I don't know that I have just an installation problem.

    But I'm trying to pass a global variable of a host program to its attached DLL.  I got this job when I was the CVI 2014. I recently upgraded to 2015 and then started getting "undefined symbols" errors.  With some struggle I managed to compile again, but broke the variable connection in the process.

    I have compiled my DLL in debug mode so that I walk in from the test project.  Right now, my global variable exists in the test project, as well as in the DLL.

    Can I export the variable and the use of DLLIMPORT/DLLEXPORT?  Confused and curiously not to find anyone quite like this on the forums.

    EDIT: this post stack overflow described pretty well from my experience.  I am linking statically.

    Well, what do you know?  I found my problem.  This draft article and example WERE vital to the solution.  This article called, "using the Export method qualifier"was also useful.  I'll cut to the Chase...

    If you use a qualifier of export on the definition and the import on the declaration, LabWindows/CVI identifier export symbol.

    This is the right key.

    So in my example, it should look like this:

    DLL fichier.c

    int DLLEXPORT varName = 0;

    Header.h DLL

    int DLLIMPORT varName;

    Project that uses DLL.c

    #include "header.h DLL.

    varName! = 1 ;  a method to change this variable for local use

    Pretty easy, huh?  But wow, it took some time to find.

  • How to call dll com APIs that range from the performance counters of less than 1 ms with CVI and always get less timer resolution of 1 ms

    Hello

    I've created a dll com in VC ++ using performance counters/timers to less than a millisecond.

    This is useful when you send a message to very high speed. (say 10 or more)

    This is done by the dll.

    When I use CVI to create a user interface, this dll runs at a fixed rate of 1ms.

    This slows down the application.

    I tried to use the same dll with VC ++ host and it works well.

    I need to check the registry setting to see if the useDefaultTimer is set to false or TRUE.

    (I'm not near the development PC) However, by default, it should be FALSE and I have no fidle with it.

    Veuileez post any suggestions you might have.

    Thank you!

    This problem is now solved for me.

    Just the highest thread priority in the dll.

    Thank you if you had the answer.

  • calling external code (instead of dll lib)

    Hallo,

    is it possible to call external functions that reside on a static library (.lib) and not a dynamic (.dll).

    The "call library function node" feature seems to allow only the dll and lib steps.

    Any suggestion?

    Thank you

    No it's not! It is because there is not a single lib format, but in fact each compiler uses its own format of lib. Namely COFF for MS C compiler and various flavors of OMF for Borland C, Symantex C, etc. and ELF for GCC unless you are using a version of target Windows such as MingW who TRIES to follow in the COFF format. So even if NEITHER would consider allowing to bind to libs via the library node call they would be in trouble on what format of compiler to support.

    But it is quite easy to create a DLL from a LIB using the same compiler that was used to create the LIB.
