I used LabVIEW to develop a toolkit for ATE software. The toolkit is called "Test bench Framework", which includes a test sequence editor and a test engine.This toolkit features the ability to execute several different sequences in parallel.If you are interested in this kit please contact me, thank you! This toolkit is over 10MB in file size and cannot be published on VIPM, so I uploaded it to Github.Test-Bench-Framework . I used the TestStand icon inside my own sequence editor and wondered if there would be any copyright issues involved.But it's not commercially available yet.

Through Siemens' S7 communication, I got some byte type data, but I didn't know how to convert these data into the corresponding structure data of labview. It is well known that the bool of struct in TIA occupies one bit, but the bool of struct in labview occupies one byte. Has anyone dealt with it? -
I'm looking for a way to automatically expand and collapse ring controls. Example: I have already seen a method where mouse click is simulated using user32.dll when mouse entered. I just want to know whether there are any better methods available. Also I do have access to LabVIEW 2022 Q3... incase if any new property/method added, kindly let me know! Thanks in advance! -
Hi I am using the MPSSE I2C drivers over a USB FT232H device, communicating with BMP280. When I read the BMP280 device ID, it is supposed to return 0x58 but the DeviceRead vi returns 0xFF. I have used a logic analyser and can confirm that the device is actually sending 0x58, but the output from the read vi is 0xFF. Has anyone had this same problem, or can anyone suggest what might be the issue? Thanks Arj -
HI! I am new in this forum. I have searched a lot for the Labview Real-Time version 8.0 without any success. I am writing in case anyone has the link, zip, rar, iso or any format with this version. It is for an old PXI. Thank you very much in advance!

Hello, I would like to generate a manifest to modify the configuration of an executable so that it launches as administrator. For that I followed the LabVIEW link : https://www.ni.com/docs/fr-FR/bundle/labview/page/lvhowto/editing_app_manifests.html However the command "mt.exe -inputresource:directorypath:applicationname.exe -out:applicationname.manifest" given by LabVIEW does not work for me. When I run the command: "C:\Program Files (x86)\Windows Kits\10.0.22621.0\x86\mt.exe" -inputresource: "C:\Users\user_name\Desktop\exe\Installer.exe" -out:Installer.manifest Here is what I get: Microsoft (R) Manifest Tool Copyright (c) Microsoft Corporation. All rights reserved. Thank you for your answer Translated with DeepL

Hello, I would like to know if it is possible to launch an executable via a VI and if it is possible to launch it as an administrator ? Or if it is possible that the VIPM launches my VI as an adminitrator after the installation of a packet ? Thank you for your answer

Hello, I'm trying to open an HTML file in google chrome via the VI System Exec.vi under NI Linux, for this I had to install the "xdg-utils" package. With the Linux terminal the command "xdg-open [file path] works fine. However, when I execute the code with LabVIEW the VI returns the following error (standard error indicator): /usr/bin/xdg-open: line 779: www-browser: command not found /usr/bin/xdg-open: line 779: links2: command not found /usr/bin/xdg-open: line 779: elinks: command not found /usr/bin/xdg-open: line 779: links: command not found /usr/bin/xdg-open: line 779: lynx: command not found /usr/bin/xdg-open: line 779: w3m: command not found xdg-open: no method available for opening '/home/lvuser/Desktop/Reports/20221128/FileHTML.html' After some research I understood that this was due to the fact that the default opening of the file is not goole chrome. So I executed the following commands in the terminal: - xdg-mime query default x-scheme-handle/http - xdg-mime query default x-scheme-handle/https - xdg-mime query default text/html But nothing does with LabVIEW it does not work but works with the Linux terminal. I join you the code (using LabVIEW 2020). Thanks for your feedback. code.vi

I am using MoveBlock via Call Library Function to copy a few bytes. The duration of this call measured with two TickCount timestamps in a flat sequence around the call is about 40ms. Since MoveBlock should be similar to memcpy in C, I thought it would also perform similarly, however, if it's really this slow, I cannot use it in a meaninful way. Has anyone else measured its duration and can you confirm my findings?

Hi everyone. I started a new VI on LabVIEW 2021 to communicate, about tcp/ip, with a led display like a billboard as image below. I get a communication as TCP/IP through the manufacturer software, but i didn't know what is the package i need to send, the full package. This led display it's a simple command use, with there software (above) or bluetooth in cell phone, but, to communicate for TCP/IP, they install a conversor, the USR-TCP232-T2 module, as image below The image bellow, I show the simple program im LabVIEW to command this led display but the main question is: whats is the kind of package i need send to show the message or change the configuration of the display. In attached, we can see the datasheet that manufacturer send us about this led display and the package to send, but i did'nt undestand how to do 😕 It's my first time towork with TCP/IP on LabVIEW manual progração Serial TechnoLEDs padrão RS232-RS485-TCPIP v8.pdf Something like this:

I am using the MUSIC algorithm and the Vector Antenna to determine the AoA of the incoming signals in LabView. My question is how can I implement the Steering Vector for the Vector Antenna in LabView? The mathematical equation of the Vector antenna is in the attachd, where 𝜙 is the azimuth angle and 𝜃 is the elevation angle.

Hello Everyone; How I plot the timestamp in the graph of the x-axis and numerical slider the timestamp given in 2d array. The array in 2d array of string... I will try this but it not plotting full timestamp can you help me to short of this problem. It will be a plot, but a few timestamps will plotting How I plot full timestamp and date... I have attached my problems like the jpg file and .vi file for your reference. Does anyone have solution comments below... 5_6285044541540009090.vi Thanks and Best regards... -
I was trying a python http communication tutorial - https://aiohttp-demos.readthedocs.io/en/latest/tutorial.html#views - when I had to disable the NI Application Web Server to proceed. And then I thought, what the **** am I doing? Maybe I should take the free (well, prepaid) gift of a working web server. Here's my task. A central HQ computer will have a GUI that monitors five machine stations, each of which has its own computer. Every approx 10 ms (negotiable), each station gives a report consisting of two arrays, the larger being 2048 data points, the other much smaller. Whenever HQ feels like it, HQ can tell a station to start or stop (its computer stays on). A local IP connection is used, with a router at each end. There is also a Raspberry Pi with its own IP address at each station's router, that can send camera frames to HQ. The station-computers use Python and C++ to do their work, not counting whatever needs to be added to communicate with HQ. Your advice please? Should I use Labview? On both ends or just the HQ? And which if any of these helpful add-ons suggested by Hooovahh should I use?

Hi! I have to convert a dynamically generated array into a JSON string and back. Unfortunately I found that the un-flatten method loses the variant data. See the screenshot of FP and BD and the comments inside. JSON_Text_test.vi Is this a bug in JSON Text or is my data-construction not supported as expected? In case of the letter I have modify huge parts of my code. So I hope that it is a bug 😉 The 2nd thing I recognized is that the name "Value" of the cluster is not used during flatten. Instead the name of the connected constant / control / line is used. I found the green VI ("Set Data Name__ogtk.vi") at OpenG Toolkit that allows me to programmatically set the variant data name. As you can imagine I would prefer not to need the OpenG VI. Thanks in advance for your kind help 🙂 -
HAs anyone tried creating a sub vi programmatically by selecting the set of blocks through scripting?????

TDF team is proud to propose for free download the scikit-learn library adapted for LabVIEW in open source. LabVIEW developer can now use our library for free as simple and efficient tools for predictive data analysis, accessible to everybody, and reusable in various contexts. It features various classification, regression and clustering algorithms including support vector machines, random forests, gradient boosting, k-means and DBSCAN, and is designed to interoperate with the Python numerical and scientific libraries NumPy and SciPy from the famous scikit-learn Python library. Coming soon, our team is working on the « HAIBAL Project », deep learning library written in native LabVIEW, full compatible CUDA and NI FPGA. But why deprive ourselves of the power of ALL the FPGA boards ? No reason, that's why we are working on our own compilator to make HAIBAL full compatible with all Xilinx and Intel Altera FPGA boards. HAIBAL will propose more than 100 different layers, 22 initialisators, 15 activation type, 7 optimizors, 17 looses. As we like AI Facebook and Google products, we will of course make HAIBAL natively full compatible with PyTorch and Keras.

I would like to build a model using image data and NI-cRIO-9063 and NI 9264 for voltage control. for image, I made a script in python using OpenCV libraries that detecting some points . For voltage control, I use cRIO-9063 with NI 9264 voltage controller. My question is, I am new in LabVIEW and I don't have any idea how can I make a loop for voltage control in python. Is there any library available in python that directly connect cRIO and NI 9264 devices? if not then how can I combine my image data(which is in python) with cRIO device? I need argent help.

Hi there, I am working on a machine vision project with LabVIEW. The camera will locate some parts and send their coordinates via TCP/IP and I created a client also with LabVIEW to display these coordinates here is how the communication going. First, if the camera detects something then msg will be sent to the client to inform him. then if msg was received correctly client responds with another msg to request the coordinates. at last, the server sends the coordinates to the client. here I faced some problems 1- the msg sent are with variable length ("x=0,y=0,Rz=0"==> "x=225,y=255,Rz=5" ==> "x=225,y=255,Rz=90" length vary between 16 and 22 ) with the constant "byte to read " it will not display the full msg. 2-the client works fine but at a certain time, it shows errors like ("LabVIEW: (Hex 0x80) Open connection limit exceeded";;;;;; "LabVIEW: (Hex 0x42) The network connection was closed by the peer. If you are using the Open VI Reference function on a remote VI Server connection, verify that the machine is allowed access by selecting Tools>>Options>>VI Server on the server side"

I am just starting on trying to be able to use Python code from a LabVIEW application (mostly for some image analysis stuff). This is for a large project where some programmers are more comfortable developing in Python than LabVIEW. I have not done any Python before, and their seem to be a bewildering array of options; many IDE's, Libraries, and Python-LabVIEW connectors. So I was wondering if people who have been using Python with LabVIEW can give their experiences and describe what set of technologies they use. -
I have installed Labview 2020 on Dedian Buster using the rpm to deb conversion method via alien. Due to Architecture mismatch i deleted the *i386.rpm files before conversion. My Problem is that after creating a project at "Build Specification"-> "rigth click" i am only able to select "Source Distribution". Application does not show up as an option. I will be grateful for any suggestions. Thank you in advance.

CLA_ATM_QMH_PRACTICE.zipHi Folks, I'm taking the CLA exam in a few weeks and would like some feedback on the solution I put together (attached). A few specific questions: Can I dump tags in the VI Documentation of the VI like I did in Error Handler - Console Error.vi and get credit since there are instructions for developers to complete this work? This would be my strategy if I run out of time. Does this seem like a passing solution? Why/why not? Where do you think I would lose the most points in this solution? Any other feedback on this exam or general strategy tips are greatly appreciated! Best Regards, Aaron
