I'm not sure I undestand the question. LabVIEW FPGA can handle math caluclation, although decimal numbers are a bit cumbersome, and the straight line formula is pretty straight forward to implement. Are you sure you need a LabVIEW FPGA for this? Do you have a very specific application?

Yes, exactly those signals! PXI Triggers. I don't have specific experience of the PXIe-7975R but I use the PXIe-7820R quite a lot. And on that card you can simply access the trigger lines like any other digital I/O in LabVIEW FPGA. So it would be fairly simple to use Wait on Any Edge or something like that. https://www.ni.com/docs/en-US/bundle/understand-flexrio-modular-io-fpga/page/fpga-io-method-node.html

Cannot you use one of the PXI trigger signal routing? https://www.ni.com/docs/en-US/bundle/pxie-6672-feature/page/using-pxi-triggers.html

If you a certain you already have a functional license, check the license folder and remove any old ones. Those can confuse NI License Manager. The path to that folder is c:\ProgramData\National Instruments\License Manager\License at least on my computer.

Both your links were good. I've found the second one, but the first was new to me. But you are right to assume that I'm looking for something less abstract. At least, that is what I want to create here—a cooking recipe of sorts.

Hi, (This is a repost from NI's community forum. No answers there so I'm trying my luck here 😀 ) As many of you are likely aware, TestStand is a powerful tool with numerous features and incredible flexibility. While these aspects are undoubtedly valuable, they can sometimes result in the creation of test sequences that are challenging to read. In my workplace, particularly with many newcomers learning TestStand, there's a tendency to be awestruck by its programming language-like capabilities, leading to the use of excessive loops, parameters, and if-cases where a simpler, flat sequence would suffice. Recognizing the need for clarity in test sequences, I've taken on the task of creating a style guide. The aim is to keep sequences coherent without unnecessary complexity. My question for the community is whether anyone has already developed such a guide and is willing to share it? Thank you in advance!

I've always thought LabVIEW's higher level of abstraction somewhat reduced the need for that. But I'm not proficient enough in any other language to make a fair comparision.

Interesting take but does it fly with TestStand?

Well yes from a data structure point of view it is. It would make sense to store the private cluster as the private data of the class and use a public cluster as an exposed API. But solving the same issue with a library isn't that different. It doesn't however solve the issue of connecting the public and private data in some smart way. But @LogMAN provided an interesting solutionf or that! I'll look into it!

So yes I went for "brute force". But I managed to solve it using VI scripting, i.e. automatically creating undbundle-by-name from the public cluster to bundle-by-name to the private cluster. So even if the creation process is obscure the result is easy to read by someone who knows only little LabVIEW. Which was what I was aiming for.

Hi, So I have this situation where I want to flatten a cluster to a byte array for data transfer. But as things are there are empty spaces between some of the parameters, call it reserved according to the format specification the cluster mirrors. So to make the flatten process as simple as possible I want to be able to traverse the cluster in a loop so the cluster must self-contain all information. I am currently solving this by including dummy parameters between the real ones to reflect these reserved areas. But of course, as you all probably agree upon, I do not want to expose the dummy parameters to the user (the vi will be accessed by Teststand btw). Som my question is: can some controls in a cluster be private somehow? And if not is there any other smart way to solve it? My current solution to this is to create a "public cluster" without these dummy controls and move data between. So a secondary question is there any smart way to do that? I want to keep my code as flat as possible so my idea is simply to use bundle/unbundle but create it using vi scripting.

Yes! NI is now Emerson Test & Measurement headquarted in Austin. So will the corporate colour scheme revert from green to blue now to complete the circle?

I must add that "small" doesn't necessarily imply "bad." I have never experienced LabVIEW, or the LabVIEW-centric world of electronic testing, to be anything other than a niche. But yeah, that niche can be strong and thriving or weak and struggling. To be honest, I don't know why I'm speculating here. I've been working for over 10 years, exclusively for two companies. I know very little about the world around me. There might be strong pockets of hardware companies with R&D labs equipped with NI equipment everywhere. I just haven't heard of them because they get overshadowed by the noise surrounding software, AI, machine learning, and other "hyped" technologies

The point I'm trying to convey here is that people often become closely associated with their roles in their respective fields, not necessarily as a programmer in the language that dominates in that field. For instance, if I've been a front-end web developer my whole career, how does that experience help me when trying to land a job as a data scientist? Saying that both positions use text-based programming languages doesn't cut it. If you ask me, the biggest problem with LabVIEW isn't LabVIEW itself but rather the fact that the field it excels in, such as electronics testing and measurement, isn't as thriving as many other software-centric fields that exist today. Our company has real-time test systems built with NI/LabVIEW. And we still develop new ones! Such systems aren't very common around here, with or without LabVIEW, compared to the plethora of companies making apps and other software solutions. Which wasn't the case 10/20 years ago. I am more worried about our company scrapping electronics testing altogether than moving away from LabVIEW. 😅

Isn't that always the case? You're a front-end web developer first and a JavaScript coder second. Knowing the syntax of the preferred programming language is just the first step. I do know that Python is often depicted as the culprit in the downfall of LabVIEW, but I hold the opinion that the main reason behind the perceived decline of LabVIEW is that the field where NI is dominant simply isn't as big as it was 20 years ago. At least from my own horizon.
