• LabVIEW FPGA code changes

  Hello

  I'm working on 802.11 application, I tried to change the FPGA code.

  I really need to compile all the code after changes? or just save the VI to observe the effects of the change.

  Yes, LabVIEW code must be compiled using the FPGA Toolbox after you make all the changes. I think the only exception is when you run mode simulated on your PC.

  Hi Neil,

  How to write you SD card?

  The SD card slot only is not currently supported in point 1.1 of the ARM.  The next version of the ARM should support this device.  Once this is the case, you can access the SD card using the primitives of e/s files.

  How to use CAN, SPI, I2C and UART?

  I found an example of UART in the Finder for example OR in Modules and Toolkits > ARM > Luminary Micro > protocol drivers > Comm.lvproj series.  I will attach also a project that uses CAN communicate with the LMS2110.  As for I2C/SPI, I suggest experimenting with the screws for this (located on the ARM > palette SPI and I2C) and consultation of the other threads on the use of these screws or create another thread.

  How to use the OLED?

  There is an example of this in the Finder for example OR in Modules and Toolkits > ARM > Luminary Micro > Device Drivers > OLED.lvproj.

  Is it possible to use the FIFO memory with labview ARM and how?

  FIFO on ARM is very similar to the desktop.  These screws are located in the data Communication > synchronization > FIFO pallet in real time.  There are several examples on how to use these FIFO on ni.com.

  Is it possible to target the daughterboard with Labview, this Board includes a processor LM3S2110?

  You can provide this Commission with CAN, as shown in the attached draft.

  How communicate between a time critical Vi which runs on the ARM processor and not time critical Vi host that runs on the PC?

  See the related example. RT FIFO If you use the FIFO screws I mentioned above, you should be able to do something similar.  I suspect that the FIFO is used to communicate between a critical time timed loop and while loop a criticism.  The while loop would then use TCP/series (or even shared network variables) to communicate to the host.

  Good luck

• Resource not found. -LabVIEW error code load 3

  LV2011 XP SP3

  I created an executable of LabVIEW by using a party lvlib 3rd screws (the screws in this lvlib are only stdcall (WINAPI) CLFs.)

  After you have installed the RTE of LV 2011 on the target computer, I copied the .exe and the necessary support files. When I try to run the executable, I get the following errors for each VI used from the 3rd party lvlib:

  LabVIEW: Resource not found.
  Error loading VI 'thirdParty.lvlib:any.vi '. LabVIEW support 3 error code: could not load façade.

  This 3rd party lvlib is included in the application under dependencies Builder. In addition, none of the screws to have their facades open. (They have the appearance of the default window properties). I also installed the thirdParty.lvlib on the computer target in the same directory structure that the Application Builder uses. (It is interesting that the DLL is taking in charge the CLFs in part 3 lvlib live)

  Any thoughts?

  Screws serving as the library would automatically be included in the executable, so there's no need to install the library on the target computer. It seems to me that you have a missing dependency for the DLL. Perhaps, the DLL requires another DLL? Where is placed the DLL?

• Existing communication usb - hid in labview c code using

  Hello

  I want to write a simple temperature using labview recorder and an external hardware that communicates via usb - hid. The external hardware uses an ATMEL 90USB162 µC and probes DS18B20.

  Link to the material:

  http://www.diamex.de/dxshop/USB-temperatur-sensor-Tester-fuer-DS18B20

  The source of a simple command line tool is available (see attachment), which reads the value of the temperature of the connected sensors.

  Is it possible to include this c code in the labview application to simplify the communication?

• How can I convert labview for code text code?

  Hello

  I have a LabView code that is complicated by a device manufacturer (LakeShore). I want to convert it to a simple LabView code. I think that the best way to do first is to understand their algorithm. Is there a way I can "convert" Labview code to a simple text algorithm?

• Is there a way to determine the equivalent ANSI C code of a Labview project?

  I'm a complete newbie to Labview.  I have this quite complex Labview project that was used to create a DLL that matlab may call to order my card PCI-6534 without having to know NIDAQmx calls.

  I am trying to find how to make these calls directly from Matlab NIDAQmx, but I do not get the same results when I call this DLL mentioned above, so I thought I would try to give a sense Labview projects live I begins to make sense of the general economy of the screw, but I would like to be able to run the project , step through it and perhaps see NIDAQmx orders (or something equivalent, so I can determine how to call NIDAQmx commands in Matlab).

  Is this possible to do?

  Thank you

  Jason

  Yes. The toolbar allows you to turn on highlighting so that you can run the VI and see the content of the son. You can put sensors on the wires. You can single-step through the code. This is explained in the help of LabVIEW under Fundamantals-> running and debugging screw-> Concepts-> Debugging Techniques.

  In what the question implied in the title of your message, don't you can directly convert LabVIEW C code in the development environment. Yes, there are tools to convert LabVIEW in C, but which is intended for microprocessors.

• Exchange of data between the internal and external labview code

  Sorry for a simple question.

  I have a TestStand sequence that uses units/tests written in LabVIEW. The sequence is extermnally began with a stand alone LabVIEW program. I need to establish simple exchanges of information between units of the sequence LabVIEW and LabVIEW external code.

  Information are simple strings will eventually be sent in both directions.

  Please advice what commumnication path needs to be implemented.

  Unfortunately, arttempts to search OR site Internet (or Internet) result in a large number of irrelevant information. Probably, I can't shape appropriate keywords. There is therefore a need for your help.

  Thank you

  EDIT: Btw, you should use TestStand user to nicks track management. This gives you more options and security than some custom stuff implemented in the user interface.

• LabVIEW version of the source code of the NOR-DCPower Soft Front Panel

  I work with an SMU NI PXI-4130. There is a front panel soft exe called the "NOR-DCPower Soft Front Panel" that can be used to control the instrument. I was wondering if there is a version of LabVIEW source code for this driver?

  Jim,

  as much as I know there is no LV source code provided for the Soft Front Panel. But there are a few examples of LV, which will be close to the characteristics of the SFP. So I suggest to you to dig in the examples you find in the Finder of the example.

• Error code LabVIEW-63040 sbRIO 9632

  Hello.

  I am trying to run the VI roaming on my kit NI Robotics Platform 2.0 and it gives me the error-63040 which is a communication error. This is not the first time I try to run homelessness, as I've been able to do it before with success (on another computer), but now it gives me this error. I looked around different ways to solve this problem, verify that it is the IP, making sure that the PC and the robot are on the same network and even formatting sbRIO Council and reinstallling software, but nothing seems to work. I can't find another way online to fix it.

  The code seems to compile right but then the robot does not move. In the picture attached, I have highlighted the process so that you guys can see what I'm talking about.

  Any help on this would be appreciated!

• Implementation of CPP code in FCR

  Hello world! Is it possible to integrate the CPC in Labview Communications code?

  In Labview original, it has been possible through "library function node", but there is no such node in FCR. Of course it is a node C but is useful for simple applications, if I'm right.

  Hi Xkela!

  Unfortunately, this is not a feature of LabVIEW Comms at the moment. At best, you would be able to use the node C as you noted, or you can use the Exec System node to call the DLL from the command line.

  Kind regards

• Can LabVIEW Embedded for ARM works with any Board or just with a few predefined?

  Hello

  Can LabVIEW Embedded for ARM works with any evaluation committee or just with a few predefined (MCB2300, MCB2400 and EK-LM3S8962)? I ask this question because even if I chose "another processor" in the definition of the new project only 3 options are the corresponding arm of Phillips and LuminaryMicro.

  Thanks in advance,

  Howdy,

  LabVIEW for ARM supports the feature of targets for tier 1 (the mentioned Evaluation Committee) following this schema:

  http://zone.NI.com/DevZone/CDA/tut/p/ID/7066

  But you can transfer to other weapons if you follow this porting guide:

  http://zone.NI.com/DevZone/CDA/tut/p/ID/6994

  The uProcesser SDK is intended for the port of other targets of DEPENDENCE (32-bit, of course) and technically it covers ARM as well. Alternatively, there are the LabVIEW C Code Generator: http://sine.ni.com/nips/cds/view/p/lang/en/nid/209015

• using the module time real Labview in RTAI

  Hi all

  I want to use the module time Labview in RTAI real for real time due to its open source applications and very good performance. is it possible to make this work?

  If this is the case, can anyone introduce a single study of case or something similar to this?

  I don't think it's possible for anyone outside of OR. LabVIEW Real-time supports this time only Windows as host and as a target only material of National Instruments with specifically targeted OSes or the Pharlap ETS system on x 86 systems with hardware specific enough. Using RTAI as target OS for LabVIEW Real-time applications requires first a few changes on the time plugin real LabVIEW to support this new platform.

  None of the files in time real LabVIEW also created for either platforms OR running VxWorks or OS Pharlap, Pharlap ETS system woud be able to be deployed to a system RTAI, because they are not compatible. In the first place, you'd have to port the bunch of shared libraries that make up the time target real system running LabVIEW on one of these goals to your RTAI system which is in fact a whole new platform of LabVIEW you can create with a little effort from the LabVIEW source code. It's not really impossible for OR as most of the code LabVIEW is written platform completely independently, but it would be a combination of the parameters compilation for course LabVIEW Real-time, with the settings to produce time targets real LabVIEW VxWorks with some additional settings of Linux. Yet, it would be by far not trivial and some parts are actually hardware specific drivers that must be worn too and limit the possibilities of what RTAI material could serve even further. In short not something that would make any commercial sense NC because they invest a lot of resources with no opportunity to sell additional hardware.

  And hell freezes over up front release of NI LabVIEW source code in any form which gives access not - OR used to it!
