• zedboard Xilinx Zync 7000 interface using labview

  Hello

  I'm doing my thesis in Zedboard for the development of a test for DDR3 memory and verification. For this I need to set up a base of dedicated on NI Measurement Studio LabVIEW graphical user Interface.

  Theme: Algorithmic Szudy of test set-up for DDR3 SDRAM with a Xilinx architecting.

  Here, I made my algorithm Xilinx SDK. But I need to create a graphical interface using labview. To run these programs. Please let me know how I can do this.

  1 or is it possible to directly access the SoC architecting using Labview. If yes how?

  2. or if I have to do the coding of Xilinx SDK and how do I run this code using Labview?

  Please give me a detailed answer. As I am new to labview. I m not understanding how to start with. If you have any design example please share with me.

  Thank you best regards &,.

  No you can not grow directly in LabVIEW and deploy this program to the Board of Directors Zync. NOR has their own material base platform Zync (cRIO and myRIO) but the tools to target these tips are specific to the hardware implementation OR and will not work with other hardware. Develop an interface for another hardware platform is a lot of work and must be adapted for each unique flavor to a new hardware platform. And NEITHER does not support this for other devices.

  If your option will be to develop an application with the SDK Zync for Zync ARM controller and provide a form of communication interface (serial port, TCP/IP, or similar) to this application you can send commands to LabVIEW for your embedded application.

• tools for interfacing in Labview

  My project is to create a multi parameter diagnostic tool to monitor the temperature, ECG waveform, analysis RVH, measure SPO2 and BP without a lapel. I would like to know the tools of different interface that I can use for my project

  LabVIEW supports a large number of interfaces: series, Ethernet (TCP/IP, UDP), communicate with the driver dll, contact OR and Acquisition of third-party data (DAQ) devices (e.g. USB DAQ, cDAQ)

  I suggest that the first thing to do would be to look at the material you want to use and what interfaces they offer (or to use sensors... analog? digital?) -You can then think about the use of this interface in LabVIEW.

• Interface using labview instruments

  Hello

  Can I interface a micropipette with PC using the LabVIEW DAQ module? This kind of micropipettes (electrically powered) available on the market?

  Hi Aruvnam,

  You must ask these manufacturers to check availability!

  'Interface to a PC' should be a point in your list of requirements that you must discuss with these manufacturers!

• interfacing of labview with relays

  Hello

  Could someone please tell me how could interface labview in a relay at the hardware level external to the switch of a circuit path. Thanks in advance...

  Concerning

  GPIB isn't DAQ hardware. If you have a GPIB instrument that has a kind of switch, you should mention that first place and if you want to help in the control of this instrument, provide the brand and model. I also hope that you have already checked for an instrument to aid driver > find the instrument Drivers.

• How can I control Sierra Instruments MFC using LabVIEW without the necessary drivers?

  I am trying to program these MFCs with labview and it would be much easier with the drivers. I have chekced OR network driver and can't find anything. If anyone knows how to program controllers without drivers, or even better, if anyone knows where I can find the drivers, it would be much appreciated. Thanks in advance.

• Control CMD (command line interface) using Labview 2011.

  Hello

  I'm trying to control software that has an interface to command line using LabView 2011 but I have problems when reading the information.

  Is attached the VI I created so far, but it is not working properly.

  Problems so far:

  1 - if I use ReadLine(), it blocks showing no error and nothing else.

  2 - ReadToEnd () same problem as the previous line, the software hangs just at this stage.

  3 - if I compare the response of the "peek" in waiting for the - 1 indicating there is not more character, the hook of software as the previous steps.

  You have some clues as to what might be wrong or another way to 'control' the CMD to send messages, read and send messages, etc...

  Thank you very much for your help.

  I've done it before - I posted about this on the forum here: https://forums.ni.com/t5/LabVIEW/How-to-open-close-and-monitor-a-application-xyz-exe-using/m-p/32511...

  I did also wrap in a library at a given time and post it on the forums, but I couldn't find this particular post.

• Read the output values after each step runs in the User Interface of LabVIEW

  Hi all

  Development environment: TestStand 2010 SP1 and LabVIEW 2010 SP1

  Problem: is there a way to run the following steps programmatically and get values out of each of them?

  I have already extended a bit a complete interface IO for TestStand load any sequence, choose among the measures and execute step by step (something as an alternative to the steps run selected). What I'm trying to do is to add some actions between each step and do in the UI (I can't change the sequence!), so I start the NewExecution with some previously configured InteractiveArgsParam and option breakAtFirstStep set to true. Eventually I do just something like step over when debugging the sequence and it works well, but I didn't do well a way yet to read the output values of the place...

  So, if I wait before the end of the run I can read my results by treating the ResultObject, but it works only after the completion of the test sequence. Because I wanted to stop after each step, read the values, do some actions and continue to the next step, I've tried to register a running Trace event reminder View Manager. I see that after each step is executed, this event is fired, but when I try to read that a ResultObject returned in the event data it is not filled with values (ResultList seems to be empty?). Is this a correct behavior or maybe I'm reading the wrong way? (It's the same VI regarding the reading of the ResultObjects after the sequence ends and there it works very well for tables, containers and other types of data).

  As I mentioned I can't change Test sequences, I can not add a UImessages.

  What are my options? If the trace event returns output all the values from each steps or is it just used to check the status? Or maybe there's a completely different approach to this issue?

  Thanks in advance for your suggestions,

  Best regards.

  When you manipulate the UIMessage trace (you need this before the return of the event or you will present the race conditions), download myuimessage. Thread. Then call Thread.GetSequenceContext (0, & Iplease).

  And then on the context of the sequence, either go to PreviousStep.Result if it exists, or watch Locals.ResultList.

  Trace events occur between the steps executed step the more recently is the previous step, but it is also a trace event to the beginning before any measure have run at this time, there will be a previous step.

  Hope this helps,

• The interface of LabVIEW and matlab

  Hello, I want to interface LabVIEW with MATLAB using the TCP/IP protocol for data transfer. Can anyone, please give me an instruction step by step how to do this? If not, can point out you where I can get them? Thank you.

  Hi Gilles,.

  TCP/IP is a generic protocol then you should easily be able to build enough interfaces TCP/IP for your LabVIEW and Matlab code and data transfer on ASCII or variants, etc., depending on what kind of data you are trying to transfer. I'm not too familiar with Matlab, but on the end of LabVIEW, there are a few examples of server and client very good TCP/IP provided with LabVIEW.

  Another option you may want to, and the reason why I answer it is that I did recently a project through which we took some legacy code MATLAB which we wanted to transpose into LabVIEW, so that we can automate then completely a test system that we use TestStand. A big part of it, we have been able to derive equivalent LabVIEW, but some functions where LabVIEW does not have an equivalent appropriate, or where it was simply more effective, simply copy us and paste Matlab code in any event in the first instance MathScript nodes (not dependant on Matlab) or Matlab script nodes (which will return if all goes well at a later date to transpose in full) LabVIEW for that is no longer dependent on a Matlab license).

  In both cases, the facility to do this was very impressive, and we were able to wrap huge amounts of code Matlab LabVIEW with very few problems. As an idea, have you considered your functionality of Matlab of packaging in this way and keeping all the customer TCP/IP and comms server in LabVIEW?

  Note: If you have not found it pick up the palette "Matlab Script.

  Good luck

• Interface between LabVIEW and c#

  Hello

  IAM trying to send data to Labview via ithernet in a product that already have in c# .net. This means that data send LabVIEW must be posted in c#. Thus the Labview will act as the server and the product in c# will be serving the customer. I have serached in the forums to make the connection between Labview and c#. I saw a tutorial to make dlls in labview, in what they explained to hold tools > Build Application or shared Library.But I can't find in my tools although I version2009 of professional development.

  Can someone give me some instructions to send Labview data and display it in c#. IAM attaching the VI Server I made. The client in c# is a great product that has already done by others in c#. I have very less experience of programming in c#. Can someone give me some instructions or attach a few tutorials to make the connection between Labview and c#.

  
  

• access to objects in the user interface of Labview ResultList

  Hello!

  I would like to have access to Locals.ResultList TS [] objects in UI (LV) during test report generation.

  According to TS help in this point I can get the context of the sequence to the sequence of process template file that sends the UIMsg_ModelState_PostProcessingComplete message.

  But my sights are found in the context of the client's sequence file.

  Can I have access to the Locals.ResultList objects with file for the model intended use context?

  Is there a way to get the desired data?

  I have references to the file in the sequence and execution in this point and tried to use the Execution.RunTimeVariables property.

  But not able to get the data searched with any supposed this object search string.

  Thanks in advance for any ideas.

  Hi, Horbert

  Thank you much for the help!

  This time I found useful object to me: Execution.ResultObject.

  It refers directly to ResultList.

  However your variant is also very useful.

  Thank you once again and I cancel this topic.

• How to interface ADAM 4060 in Labview 7.0?

  I had difficulties in interfacing ADAM 4060 with Labview 7.0. I tested the device by using the utility software of Advantech ADAM and it works properly. So, its not the hardware error or failure.

  However, when I want the interface using Labview, I couldn't make it work. LabVIEW does not communicate with ADAM-4060. I try to use user libraries > Advantech DA & A > Advanve > SlowDIO > DioWritePortDword.vi, DioWritePortWord.vi, and also library standard srandard, COMWrite.vi

  Hi a - kay,

  Where did you find this instrument driver? I'm not on IDnet. What is the manufacturer? They may have more documentation?

  In the other thread, you will notice that it is simply a communication series. You may be able to write your own driver quite easily.
