  1. My project involves designing a front end for a synchronous generator using LabVIEW. It is actually data acquisition and display of signals in a file. The problem I face when building a program is that: 1)the sampling rate is set to 100 samples with 1 kHz sampling frequency.These signals are generated by daq assistant and i have used merge signals to merge these signals from daq assistant as well as signals from other radio buttons and Boolean as well. The problem is that when written on a file I am able to see only one instance of Boolean status for every 100 samples daq assistant creates. 2) now iam able to write only 0/1 as status of Boolean in the file.How will I write on /off into file?

  3. Hello, I'm trying to send data from my RPI b+ to labview and store the information in a spreadsheet, right now the data I'm using is just a sawtooth generated in the python code but eventually it will be sensor data adquired via spi, the data comes at =~ 6-7khz but the time it takes to send the data to labview is much greater, I fear the circular buffer I intended to use to store the data before sending it via tcp will get filled pretty fast. I'm not very experienced in either python nor Labview, I was wondering if i could get some advice in the optimization of the code. I attached the VI of the client and a VI that graphs the data on the spreadsheet, also the python code. Thanks in advance, sorry for the mess. Waveform Grapher.vi Client.vi serverSerial.py
  4. Version 1.0.0


    There it is. The complete library for the MCP2221A. I2c adapter, I/O in a single IC. I love that one. Let me know if any bug is found. I try to make that library as much convenient as possible to use. Two version available 32 bit and 64 bit. little note: to open by serial number, the enumeration need to be activated on the device first. (open by index, enable the enumeration) It needs to be done only once in the life time of the device. PLEASE do not take ownership of this work since it is not yours. You have it for free, but the credit is still mine... I spent many hours of my life to make it works.
  5. hello there i'm stuck with my assignment. i have made a VI that generates random number and writes the data to CSV file I have added a timer stamp in the first column now i want to get the data for every 5 seconds using wait function how do i do it ? Thanks in advance 2d array random no v2.vi
  6. Hi All Apologies if this isn't the correct forum to post this on but I wanted to let the community know about a new LabVIEW podcast series I am running - The Quick Drop Podcast QDP LogoQDP is a community driven podcast that I want to use to talk about LabVIEW and engineering/Science in general via a medium that I don't think we currently make the most of. So far we have 2 episodes which are available on most podcast platforms (i'll link some below too): Ep 0.1 - Intro: A brief intro to me & rasons behind the podcast Ep 1.0 - NI Linux Real-Time Controllers with Neil Crossan: I am Joined by Neil Crossan, a Certified LabVIEW Architect, TestStand Developer & Certified Professional Instructor who works in ATE development. Neil shares his experiences with the cRIO platform & some headwinds he's had using the current platform as well as addressing some of the ways he's customised and optimised the NI Linux Real-Time OS. I am actively looking for more people to do episodes on, so if you have an idea please contact me: E-mail: info@tthequickdroppodcast.com Twitter: @quickdroppod Links: Apple Podcasts Spotify Anchor Stitcher Thanks!

  7. Manufacturing a satellite or a simple pen require to test the quality of the product before delivery to the customer. LabVIEW is widely used for that purpose. Since 20 years of LabVIEW development I saw numerous test framework. I was wondering if people where interested to work in a collective and open source test framework. Per example the following feature can be included: HAL (hardware abstraction layer) Database to record test results with the data viewer (PostgreSQL) single/asynchronous/batch/debug mode multi-language support Image analysis (open CV) + bar code reader User access level Remote monitoring Jig identification to prevent user error (testing the wrong product with the wrong jig/test sequence) HTML/xml/txt report and so on....

  8. One of the main topics of the 2018 CLA Summit was the need to improve access to open source code in the LabVIEW community. This is something that I have tried to do in the past with limited success. After hearing what others are doing and discussing the issues, I am inspired to take on the task of getting as much of my code that is shareable out into the open for others to use, improve, learn from and critique. So, the point of this thread is to figure out how best to do that. I have tried posting code to forums in the past. I have even posted to the code repository here on LAVA. I have used code posted here and via the tools network and VIPM in my own projects. But I am not sure if any of those avenues are the right path forward for me. There was much discussion about different open source repositories on the interwebs that we could leverage. There was also some discussion about how to help others discover the code you shared. What I did not hear was any definitive conclusions on how best to do this. So, the point of this thread is to try to solicit feedback on code sharing and come to some sort of consensus on the best options out there. If you have an opinion on this please join the conversation and share what you think is the best solution. Here are some questions I am trying to answer: 1. Where should we share code? What system works best for LabVIEW code and is user friendly enough to not discourage people from using it? Please share links and how-to documents for your preferred site/system. 2. How should we license code? I heard some discussion about the various type of licenses. I am not interested in retaining any rights to code I share and do not want to put any burdens on those who want to use and learn from any code I share. What licence is accepted in the open source community that supports this kind of sharing? 3. Once we post, how do we make our code discoverable? Do we need to post links all over the place or is there a better way? Here is one attempt at making that better you should check out if you have not already: I am not just interested in putting the code out there, but also trying to explain why I think it is worth your time to take a look. I am willing to post on forums, create a blog, even produce some vlogs on YouTube if it is the best option. Please let me know what format would motivate you to take the time to learn about the open source code out there. Either way, thanks for taking the time to read this thread and contribute what you can, even if it is just to follow the discussion and learn from others like I am trying to do. -John
  9. Hello, everyone! I am studying a LabVIEW for my research. And I have a really curious question. Can I check my LabVIEW bit (ex 32bit or 64bit) through the code? I searched the property node and Invoke node to find the function which shows the LabVIEW bit. But I was not able to find it. If there is someone who knows the function, could you let me know about it? Or if I have to use the .dll to check LabVIEW bit on the code, could you announce me the .dll name? Thank you for spending your time for me !!!!
  10. Hello I am looking for a functional MQTT server client implementation for Labview. I have been doing some search, and found something, but they all seem to be unsupported. Does anyone have any pointers to a fully functional one? Is NI developing any stuff on this? Thanks Edited for correct content

    GRBL 1.1

    Version 1.0.0


    Hi everyone, Since GRBL standard is open source, I decided to post my Library that I used in LabVIEW to interface a standard GRBL version 1.1 controller. Not all GRBL function has been integrated, but this is a very good start. Enjoy and let me know your comments. Benoit
  12. Started some work on a simple C code generator for LabVIEW. https://github.com/taylorh140/LabVIEWCGen I was working on some ideas to handle some more complex Items. Had some thought about using https://github.com/rxi/vec To handle strings and other arrays/vectors, I would like to pass these more complex data types by pointer. However I am looking for some ideas as to when to make a copy. I know LabVIEW has some internal item that manages this but I haven't found a way of accessing it quite yet. Let me know if you think this is worth some effort. Or if you have any ideas about the architecture that you think would be helpful. Also i imagine that this will still only ever support a small subset of LabVIEW, the languages are quite a bit different, and i prefer that the code be as clean as possible.
  13. Hi, I'm new in Labview. I work as an intern. I have a formula for fitting a spectrum. The left side of the spectrum is higher than the right side. There's a background on the left side.I need to lower the level of the left side to the right by applying this formula. It should be a Gaussian curve. I need help. Who can help me?
  14. Version 1.1.0


    This is the only way I found how to have a bunch of color that are unique and easily distinguishable. The maximum I saw in the web was about 26. This one offer 55 of them without gray tone. You can modify this VI to support gray tone as well and goes up to 60 colors.
  15. Hi, When I try to install LabVIEW 8.5.1 runtime or visa 4.1 on an Intel NUC with CPU i5 7260U I get: Microsoft Visual C++ Runtime Library Runtime Error! Program ........\LV RunTime 8.5.1\setup.exe This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. Just in case I installed Visual C++ 2005 redistribution and checked under add remove programs that the Windows feature of allowing version under .net 3.5 to run was enabled. This is not an ARM based processor so why does LabVIEW has a problem installing on the NUC?

    Version 1.0.0


    This tool-set gives access to all the 1-wire TMEX functionality. I was able to access 1-wire memory with this library. It has all the basic VI to allow communication with any 1-wire device on the market. It needs to be used in a project so the selection of the .dll 64 bit or 32 bit is done automatically. It works with the usb and the serial 1-wire adapter.
  18. My team is looking to take on a CLD level LabVIEW developer to help build and maintain a distributed control application. This application is ultimately the Go For Launch button on our newest Air Launch platform.

The scope of this position is highly fluid; like most roles here at VO, you'll have an opportunity to become involved in projects all around the company.There is some travel expectation for this position. Approximately 10% of your time will be spent at our test site and launch sites--some of which are not continental US territories.All Virgin Orbit employees must meet ITAR requirements; specifically, you need to be a US citizen, a lawful permanent resident of the U.S., a protected individual as defined by ITAR (22 CFR §120.15) or be eligible to obtain the required authorizations from the U.S. Department of State. You can apply through the portal exposed in the requisition found here: https://careers-virginorbit.icims.com/jobs/4059/launch-engineer%2c-control-systems/job
  19. Hello, I have set up a vi in my project where it deploys startup.rtexe, web service and the related web service vi and a shared variable library to the real-time(sbRIO) target. i have 3 targets in the project 1) My computer 2) RT-Target 3) FPGA. What i want is to change the properties of the RT-Target whereby i can assign the IP address of the device to the target project properties programmatically. i can manually assign the IP address by right click on target->properties->IP address. but sometimes the IP address changes and so target cannot be reached and deployment fails. i want to be able to set the IP address through the VI and then deploy the items to the target. Please suggest a way to do this. Thank you.

  23. Hi to all, First to all thanks for being able to help and reading this post. I would like to ask two question: 1- I have RUN TIME asigned to a PC, but know I would like to change this PC and install the same application to another PC (of course, keeping the same Run Time) Is it possible and how can I do that? because when I put a run time in a PC it is associated with that pc. 2- I would like to associate the application to a PC, so if the application run to another PC it can not. I see some post that associate the application with serial number of PC and serial number of hard disk, is this the best way? Thanks a lot.
  24. I am trying to use a mixed signal graph to plot a set of digital data (12 lines) and 4 arrays of analog data in XY format. For the analog data I want each array to be assigned to a different group in the graph, but at runtime they seem to all default to Group 1 (the Pressure graph shown below). I have been able to change them using the legend or the graph properties for each plot, but cannot find a way to do it programmatically. Is there a property node that can be used to set this?
  25. Hello All, I am new to the camera labview programming. For my research work, I am using camera to grab the live image. I am stuck with one problem. how to treat the background? I tried to subtract the constant value from the entire image, but with that i am loosing few of my data. I know one solution, but I don't know how to implement this solution. Problem: how to take the values from the 4 corner of the image and subtract those value from entire image? If anybody previously develop similar stuff then please help me out for this. Any help would be appreciate. Thanks, Shaun removebackground.vi
