@The Q My library is not complete by any means, but what works really works... I've followed a TDD approach. So far I've covered only 79 requirements out of 141, and I haven't started any branches to support MQTT 5.0 yet... So it covers the basic needs such as shown in the presentation you're referring to, but nothing fancy like QoS 1 and 2 and the likes. (or TLS for that matter). If you want something more complete, I'd check Wireflow's implementation first. Now, I'd really like to get other folks to contribute to my Open Source Project. It would give me a moral boost to continue pushing it further. In the meantime, thanks for the advertisement!!!

Do you mean that you want to output the file directly to a PC, from the cRIO? You would have to write your own Test Report class and inject it using the "Define Test Suite" method. If you're up to it, here's a tutorial about doing just that. (the part you need starts around 7min20) The demo shows how to create a JSON report from the provided template, but the steps are the same for writing to a database or sending your file via FTP or WebDAV. You'll need to figure out what you need to effectively point to your PC from the cRIO (including firewall and all...), and inject those parameters in the report constructor. Let me know if anything isn't clear from the demo. Maybe this thread (on the dark side) is also relevant to your question: https://forums.ni.com/t5/NI-Linux-Real-Time-Discussions/Send-file-from-cRIO-to-Pc-using-webDAV/td-p/3463863

Last LabVIEW version in the list (profile) are LabVIEW 2018 and NXG 2.0. The list should be updated.

Hello Dániel, yes you can run Caraya headless starting from version 0.6 and on. You will first need to setup a Test Suite and ensure the "Interactive" flag is set to False. This should instruct the Test Manager to run in Silent Mode (no front panel). On a Real-time target, you can get a text report setup as part of the Test Suite constructor. There is a wiki page on github about this topic: https://github.com/JKISoftware/Caraya/wiki/Defining-a-Test-Suite Choose the Polymorphic instance that makes the most sense for your use case (plain text or JUnit-style XML report) Let me know if this does not work or you need more assistance. If you think there is a bug, you can also report it directly on the issue tracking for the project: https://github.com/JKISoftware/Caraya/issues

GRBL 1.1 (2009).zip Back saved to LV 2009.

Apparently @Benoit does not have access to LabVIEW anymore. At least until the Community Edition is released... I took the liberty of backsaving to LV 2013 and correcting the *char GpioValues bit representation as described in the programmer manual. (Only for 32-bit library) Microchip MCP2221A_x86 (2013).zip *Please note that I have never used this library and have no way of testing whether the 2013 version works.

I believe the only way to do what you want is to catch the keyboard "arrow up" and "arrow down" events, discard them and programmatically increment or decrement the control value. (LV2013) ArrowUpDown_UnitIncrement.vi

I simply have all my public repos in Github nowadays, so switching it is mainly to keep them all in the same place. You're right that I could have simply kept the address of the repo the same and changed it to Git.

Application Control >> Palette Editing (It's really just a flatten/unflatten .mnu file API...)

As I've reported in the UI Tools support page, I've started migrating the open source code I still have on bitbucket (Mercurial-based repos) to Github. I didn't think that it might be worth a specific topic until @LogMAN mentioned it. Personally, I'm moving my code to Github in the process. I know there are some reports of Hg-to-Git transitions not going so well when using sub-repositories, so please share your migration experience if you've had to jump into some hoops to get it done! For all of you who still use Mercurial and host your open source and/or enterprise repos on Bitbucket, this blog post is worth reading:

Due to bitbucket discontinuing support for Mercurial in 2020, I have migrated the source code to Github. From now on, if there is any development on this project, it will be in the LabVIEW Open Source project: https://github.com/LabVIEW-Open-Source/ui-tools You can use both LAVAG or Github's issue tracking to report any issue you might encounter with this package. (previous repo: https://bitbucket.org/normandinf/ui-tools/)

Like Eric predicted... I use JKI SMOs the most. Although I also actively maintain a couple of Actor Framework projects.

OpenG does not install under the LAVA palette. I think it was used by a few of us back when Jon Green was handling the Code Repo. I know I've put the "UI Tools" in there and I'm fairly sure there were a few more packages from the years ~2012. Ton's "Code Capture tool" maybe? The idea was to regroup the librairies that were published on LAVAG's repository into a single palette, but it didn't get much traction past 2013.

I'll be there as well. Since this will officially kick off my vacations, I will not be presenting this year 🙂. I'm eager to sit back, relax, learn and chat with all you guys & gals.

Remember that the DVR is a container which contains the class. Since your class is privately scoped, only library members can act on it. No terminals containing the DVR will allowed unless your class itself is accessible to the caller. You can still achieve exactly what you want by moving your interface methods (DVR terminals) inside your class as public members of the class. As @smithd suggested, make all your current class members be protected (if dynamic dispatch methods) or private (for your static dispatch methods) and set your class' scope to Public. In addition, you don't need a lvlib to wrap your public interface as the class is already a library.

@donk you haven't overlooked anything. Unfortunately, somewhere in the past (was it 2011?), LAVAG experienced a massive failure and most attachments from that time were lost, or at least the links could not be recovered programmatically from old thread backups.

The LWZ Unpack algorithm is very slow in the OpenG implementation. I found this post over in the NI forums and tested it with your image... much faster. https://forums.ni.com/t5/Example-Program-Drafts/Read-GIF-File/ta-p/3514726 Edit: Set image to "-1" to load them all:

Version 1.2.0.6 released. https://github.com/LabVIEW-Open-Source/DataManipulation/releases/tag/1.2.0.6 Added support to return a list of Event reference types (class of event) for Event Registration Refnums Controls, Panes, Splitters, VI References and Application References. Array is empty for all other datatypes. ** Please note that this does not drill into clusters of Event Registration Refnums. This is only one-level deep. I have not tried, but I assume that getting the cluster elements and then looping on those should work...

They show up as Generic Refnums. (0x08) If they are named refnums, they should show up as in this example where "This VI" is the label. You can tell if they are named references by the 0x40 flag. If your events are named, they will show up in the list. The type of event is set in the last long byte in the "First Element" highlighted in green in the screenshot. (xA4 10) xA4 = VI reference, x10 = Key Down. I'll add this support to the OpenDescriptor. That is definitely useful info to get! I'll report here when done.

The ~5% slower Map vs Variant Attributes is consistent with what @altenbach reported in his NI Week presentation, for very large datasets. Since one set is ordered, the other is not, it might be interesting to benchmark the "delete" operation and see if it is symmetrical. My intuition here would be that finding the key and deleting it would be ~5% faster in favor of Maps (for large datasets). Since I rarely deal with large sets, I'm egotistically happy with NI's choice to make those sets and maps ordered.

You can extract the labels from the type descriptor, once you know where to find them in the array. I added support for it in this open source DataManipulation library. Check out the OpenDescriptor palette. You can install the latest release (1.1.0.5) from here: https://github.com/LabVIEW-Open-Source/DataManipulation/releases/tag/1.1.0.5 (download VIP file and install with VIPM). Once installed, you'll find the "List Element Names" method under Addons>DataManipulation>OpenDescriptor palette. (It can list enums and cluster elements as well, although those are natively supported under the Variant Utilities palette.)

I don't have a scoop on that, other than they extended the conference by half a day and there will be a public Engineering Impact Award ceremony (whereas before it was a closed event for the nominees only). I don't know if there are more changes to the formula.

Not sure that's the issue, but lags can sometimes occur because the installed code is not compiled for the current version you're using. If you're using VIPM to install the package, make sure your options are set not to prevent compiling after installation. Alternatively, browse to the installed package folder and force it to mass compile. I've seen this behavior for code that installed under Tools menu (under LabVIEW 20xx/project) which were not compiled, so there was always a lag the first time you load it in memory. Being being installed in a non-write accessible folder, it would cause the same issue the next time you'd open LabVIEW and brought the code back into memory.

I agree with James. That could be achieved through composition and adding an abstraction layer. (Sink and Source in the diagram below)

Bonjour Antoine, I'll take a look at this. Can you tell me which version you've installed?
