• 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.

• 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.

• Interfacing Ensenso SDK using labview

  I am trying to Ensenso SDK interface using labview. The company provides a .net dll, however, all available functions are not accessible from labview. They also said that labview is not yet officially support for interface with the Ensenso SDK. But C, C++ are officially supported. Now my question is, is it possible to write code c or c++ to control the Ensenso SDK and then access the C or C++ works using labview? If so can you help me how can I do? Thank you very much for your support.

  With sincere friendships.

  If you can not get the .NET DLL to work with LabVIEW (for example the use of the call library function node), you could create a C/C++ DLL wrapper that allows you to access the functions you need. I don't know too much about the details, but it is certainly possible.

• How to use Extech Instruments model 407123 with Labview 7.1

  I'm pretty new to Labview.  With the help of this forum, I was able to configure my DAQpad 6020E with my Labview 7.1.

  Now, I'm looking at using an Extech Instruments Thermo-anemometre to hot wire (407123) in my experience and it works through Labview.  According to my research, I was led to believe that I have to use the Instrument i/o Assistant and NI-Visa, but I'm having a lot of difficulties.  First, the thermo-anemometre is wired for a RS232 interface and I connected to an interface RS232 converter USB, which is then plugged into my computer.  I have the driver for the converter.  When I plug the thermo-anemometre into my computer, MAX it reads as a serial port and it is listed as COM3.  MAX argues that the device works properly.  However, when I run e/s and Labview Instrument wizard say to read the data, I get an error of bff0015 and it says that the device has expired.  I tried to change the time and I still get the same error.  I guess that means that Labview and my device are not communicating.

  I saw a mention of the pilots of the instrumentation, but I could not find my particular device.  I guess that's the root of my problem and that if I had an instrument driver to run my device in Labview that it works correctly.  So here are my questions.

  (1) what should I take data by a third party thermo-anemometre in Labview?

  (2) am I correct in thinking I need some kind of driver instruments?  And if so, where could I find one (I have already searched for one and he did not)?

  (3) is possible and practical to take data through an instrument of party DAQpad Labview and a third at the same time?

  (4) are there guides or tutorials that I could use that can show me how to do what I'm doing?

  Thank you.

  
  

• Instrument interfacing in Labview

  Hello

  I would like a Luxtron m600 optical fiber probe so that I can use it to receive entries analog signals to control the heating of the samples of the interface.

  My obstacle becomes the sensor FOT to contact my office. In MAX, I tried to configure the NI PCI-6229 I use under "Devices and Interfaces" with the probe attached to the block connector with wire bare but couldn't create the task. My understanding is the sensor FOT being a third-party tool, I also need to connect it to one of the serial ports on the computer by using a VISA interactive control. In addition, I also need to download the driver specific to the probe.

  I downloaded the mentioned software and managed to obtain data on the temperature of the sensor with the driver. But my goal is to integrate these data at a higher level VI which will use the PID toolkit. Before, I used a USB DAQ Mbps key and had to use the explicit input function DAQ helps acquire signals. But for this application I use assistant DAQ and the Assistant of the Instrument, or is it a different thought process that will allow me to interface with the PCI-6229 FOT sensor lead? I've only been using Labview for a few weeks to get the detailed procedure would be greatly appreciated. Thank you for your time and patience.

  I have attached the driver I downloaded for reference.

  If you are unsure how to add devices to the connector pane in LabVIEW, you really start the tutorial from LabVIEW. Very basic task which should not take more than 60 seconds.

  Throw the instrument if you want to instead use the DAQ card to read the sensor. Makes no difference to me. Always plug your DAQ card for what will be the heating element. Your reading of the temperature is only half of the installation. Since you already have this part done with driver, I don't quite understand why you focus not on the part of output control.

• Possible to use labview with daq system not of NOR?

  Hello

  I have a daq system and the software from another company that NEITHER. But I want some changes in the software. If the opportunity was to make a new program with Labview.

  Is it possible to use the old system of data acquisition? Is this compatible with Labview? Or I have to buy new hardware?

  Thank you.

  Hi VIassaks,

  Good afternoon and I hope that your well today.

  Thanks for the post.

  LabVIEW can communicate with 3rd party hardware using the library function call is located in the tip under the functions Palette palette. If your equipment is equipped with a DLL at the driver level LabVIEW can communicate with the hardware. However, you must obtain documentation of the DLL so that you can create your own interface for the material of the part 3.

  Another option would be if the hardware manufacturer provided LabVIEW VIs that control their material. You will not be able to use the screws (National Instruments Data Acquisition DAQ) because these screws use the DLL OR-DAQ, which is our software at the level of the driver for our DAQ cards. Other companies use their own software to the driver level to control their own material. Only the National Instruments hardware uses the NOR-DAQ driver that allows you to use LabVIEW DAQ screws.

  Hope this helps,

• waveform, with an average of results using labview to O-scope

  Hello fellow engineers! I'm a first-yeargraduatestudent in CHEE at the University of Houston. Basically, I know nothing about labview. I am trying to program an application that looks like this - I collect a waveform of the signal of O-scope. This waveform does not change its characteristic shape. I need to find the wave form average of waveforms of N (100 for example). Thus, the slight changes (or noise) in the feature of form during the period mustbeaveraged out and I need to have a resultant waveform that represents the average waveform over a period. So, basically, I'm collecting the wave several times (for example 100) on a single period. The O-scope that I use now is Tektronix TDS 2024 B. It communicates with the computer via USB. The version of labview is 8.5. For now, I am able to communicate with the computer using our o-scope through labview. I already downloaded the driver of instruments of your Web site. It turns out that the program can give me only the average result I can get directly from o-scope manually. I need to have more say on average (100) using labview. I wrote a program that relies on the instrument driver that is downloaded on your website (for loop part is average, the waveform). The program that I modified and an instrument driver are attached. The program cannot be fully open, if the driver is not put in the right place in the labview (under lib inst.) When I run the program, the average waveform does not appear on the front panal and signal waveform file is not saved correctly. Is there someone can find where I did wrong and it develop for me? Because I barely know Labview, it will be even better if you can add an image or program that you have changed. I'm waiting for your creative ideas.
   
  With the best regards,.

  Hello

  If you plan to build your app for Windows, you can use .NET classes. (System.PerformanceCounter), there is a simple example with LabVIEW:

  C:\Program NIUninstaller Instruments\LabVIEW 2010\examples\comm\dotnet\SimpleTaskMonitor.llb

  

  Also, you have several screws that you can use to verify information about the processor.

• How to program using Labview to an accelerometer

  Hello:

  I got an accelerometer which has digital I2C/SPI serial interface, so I bought a USB - I2C converter for data acquisition. I would like to know if I can use Labview to acquire data of com port and also program for the accelerometer to capture the data of the axis z. I have a box of white myDAQ NOR but SB. says that it is not an appropriate device to acquire before I2C/SPI signals. The datasheet of the accelerometer is in the accessory and the specification of the converter is this link: http://www.robot-electronics.co.uk/htm/usb_iss_tech.htm .

  I hope someone can solve the problem for me. It is best to use the software labview for me because most of my project work is based on that.

  Best regards

  The f

  Good and bad news.  You have an accelerometer that 'speaks' I2C or USB to I2C converter, so if you connect both of them, you can send 'orders' of your accelerometer easily of LabVIEW by using communication series live that's the good news.  The bad news is that it seems that you need to address your accelerometer using calls very low level, a work, I certainly don't want to face!  This crys on a 'pilot', a middle piece of equipment that does all the "hard work" to take a high level order ("Please tell me the acceleration") and he translates things your device includes (including the Setup program, records, calendar, packing and unpacking of the bits and bytes, etc.).

• Complete equipment of simulation using LabView, Multisim, and MAX (easy answer accepted!)

  Hello, all!

  Sorry, I'm new, but I checked around for a definitive answer on this, but I'm not 100% sure.  I learn LabView for a physics of upper-division course.  We use hardware (DAQ - MX) and a mixture of laboratory equipment - mainly stuff such as voltmeters, oscilloscopes and test setup with simple components.  I also work with NIM instrumentation, but that's secondary to my needs here.  So, when I'm away from the school, is it possible to make a complete simulation of my classroom work using LabView, Multisim (for my model) and the measurement and Automation Explorer (for the acquisition of data-MX)?  I know I can create a circuit and drop it in Labview, but I'm not sure on the acquisition of data.  I hope for what is a "seamless" reconstruction of what I do in class.  I can't take a simple 'yes' or ""; as long as I know it's possible, I can find the solution.

  Thanks for the help!

  I wrote 'sim' screws in many situations where I need to work away from the hardware store.  I think that MAX has a few features, but you may be limited in the types of signals, you can simulate.

  For my sim screw, I make a copy of the original VI with ".sim" added file name.  I also change the icon in a characteristic way to identify the version of the sim card on the BD. In this way the two VI have the same connector pane and are interchangeable on the BD structure. disable the diagram can be your friend here. Inside of the VI of sim, I generate the signal in any form I want.  You can also add additional if necessary controls.

• extraction of your LabVIEW instrument

  Hello

  Does anyone know why your Extraction icon does not work in a Labview Instrument? When you try to use the Instrument of LV in Multisim, Multisim is quitting with an unknown error. If I take on the Extraction of tone icon and rerun Multisim without her, it works again...

  Thank you

  The problem is resolved. It is possible to use your snippet in a LV Instrument. The problem was something else, unrelated to the Subvi your snippet.

  I copied the Phasor_Diagram.llb and the Phaser to C:\Program NIUninstaller Instruments\Circuit Design Suite 13.0\lvinstruments folder, but

  I can't find the Labview Instrument Phaser in my Multisim.

  What's not? How to get this working?
