  1. As I read the OP the question was does zeromq fill this gap in native NI offerings? I quoted a mention of some of the holes that exist and suggest that I think they still exist. Perhaps I should add some context. I remember when this conversation first popped up as well as rabbitmq. I thought that it was just an effort to include a third-party communication protocol to make rt targets able to communicate with 3rd party devices and I don't really have *that* need. However, filling some of the holes in NI offerings is something I am interested in seeing if this is the case. I work with cRIOs dai
  2. Has there been any recent movement on this? Currently from NI I see a clunky method of flushing streams suggested for native messaging/command control, and the STM library and I don't really see anything that natively addresses the issues mentioned here.
  3. I'm curious about the FLIR cameras. I've not had a chance to use them in an application, but they have always intrigued me. If you get your problem resolved (and I think Antoine gave some great advice) can you elaborate a little on the camera and perhaps the application?
  4. Well, things have morphed a little and I may have been using some terms a bit freely. But for now I've been able to replicate the steps used in Google Authenticator for producing HMAC-based One-time Password algorithm (HOTP) with the help of this article as a starting point. There's still plenty to work through, but I was unable to find this available for LabVIEW anywhere. Perhaps I may be mistaken and there are some more fully developed libraries out there. I would love to see those! The workflow is basically that an operator needs to get approval from an administrator to proceed with th
  5. Has anyone dealt with integrating with 3rd party two factor authentication systems (e.g. Google Authenticator, Authy, Microsoft Authenticator)? I've searched around and found some information about Oauth 1.0a here but I'm not sure that is much help. The use case is an operator wanting to trigger an action that is approved by a supervisor on a mobile device. Offline authentication would be very helpful too.
  6. Right. My point is that it is not intuitive to someone who is starting to work with NI Vision. Perhaps that has changed in recent years? I have seen so many people get confused why they branch the wire and perform image manipulation operations on it and wonder why the behavior is erratic for example.
  7. A good way to illustrate what the IMAQimage reference is. I really wish they had a better way to differentiate this on the wire. I've had to explain countless times that the wire is a reference not a value, but it just feels like it should be by value unlike other things that use reference wires.
  8. I use about as many four letter words each time I find Windows wants this stuff saved somewhere else or starts moving around user docs and such.
  9. In what format do you have these signals? Array? Waveform? Dynamic Data Type? If the latter two, there are some fairly straightforward ways to re-sample and interpolate in the Signal Processing -> Signal Operation palette or the Express -> Signal Manipulation palette (Align and resample plus append signals perhaps).
  10. It has been a hot mess with trying to get 2019 installed on my laptop. It killed all DAQmx support for 2018, but had options for the other version installed. Then wouldn't uninstall correctly and the NI website has simultaneously revamped ni.com/downloads making a standalone nearly impossible to find. Can we have ni.com/src back?
  11. I believe if your word length is 16 bits and the integer word length is also 16 bits and mark unsigned you will have a FXP data type that will contain the UINT16 properly.
  12. I'm not entirely certain what your use case is, but I have found that Bookmarks in Word and Named Ranges in Excel are useful with the RGT for updating fields in a template. Especially when provided a report by the customer rather than being able to design our own.
  13. If you have the DSC module this may be what you are looking for. https://forums.ni.com/t5/Example-Programs/Creating-a-Value-Change-Event-for-Shared-Variables/ta-p/3528947?profile.language=en
  14. From my limited testing the cRIO DAQmx support is fairly limited in speed. Perhaps it will improve, but it did not fit the intended application like I had hoped. By all means give it a try though if you have the hardware for it and I'll still consider it for future applications myself. Very good points. Another thing I'll mention to customers is that each layer down involves a significant additional software component (aka $$). Not only is the FPGA a different beast (despite improvements over the years) compilation time and iterative development is slow. Like smithd mentioned, it can o
  15. Agreed with a lot of the above. Also, I tend to download lots of the attachments that seem interesting, promptly forget about them, and then months later rediscover them and think "hey that would have been nice to have used weeks ago".
  16. I just loaded a bunch of JKI VIPM packages onto a new laptop and a bunch of OpenG packages were dependencies. I would not say this is dead at all.
  17. A good use case is when you encapsulate code in a case structure based on error/no error. Common in SubVIs. The error case will usually have the error wire running straight through, while the non-error case may have many VIs that *do stuff* and don't necessarily align error wires together. I don't usually drop the line back down to the base reference in between VIs, but there are times that I'll put a few in a row, drop back down, and then come back up for another batch. It's purely cosmetic.
  18. From the one project I had with a myRIO I think some USB cameras will work and I think I got a usb to ethernet device to work without installing drivers. I would be surprised if a regular USB to Serial converter would work out of the box on a myRIO, but is theoretically possible.
  19. Have you tried using the UART lines on the myRIO in conjunction with the express vi? If that doesn't work (it should) you could attempt to install linux drivers for a USB to Serial converter on the myRIO. Good luck though.
  20. Glad you found a solution. I would encourage you to look at Hooovahh's solution again when you have time. There is a lot of value to using splitters/panes vs programatically adjusting/polling when it fits your needs.
  21. I'm a fan of paintainable as well. In a presentation just toss some quotation marks around it and explain what you mean. The point is instantly conveyed.
  22. FYI, please only post once on this forum. Mods, here is the double post with no replies that should probably be closed. https://lavag.org/topic/20311-how-to-generate-a-crio-project-programmatically/
  23. Having worked as an AE intern 8 years ago (wow, 8 years??), I'll point out that it's not the AE who won't escalate. It's the PSE or whatever they are called these days. No replication means it's an issue on your end. That was fun to explain to a customer.
