    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.

    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.

    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).

    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?

    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.

    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.

    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

    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 often be better to spend the money on hardware if applicable.

    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".

    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.

    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.

    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.
  13. Jordan Kuehn
    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.

    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.

    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.

    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/

    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.

    Do you happen to have a 3rd party piece of software to confirm your configuration settings and connectivity? What hardware are you using for RS-485? That's not a standard serial port on most machines (not that even RS-232 is all that common these days either...).

    If you have the report generation toolkit you can open a new report with the existing file as a template. Then you can call [Excel Get Data.vi] to extract the data from the worksheet.

    Definitely DSP. I don't know the book MarkCG recommended, but understanding the fundamentals of sampling and signal processing is at the heart of most of the use cases of LabVIEW. Now you can get by with the tools NI has developed for you, but you sound like you are interested in a theoretical knowledge and rightly so! If you can understand the math in a course like this, you've already got most of the more fundamental math disciplines under your belt.

    This touchscreen keyboard was discussed a little while ago: http://forums.ni.com/t5/Example-Programs/Touch-Screen-Keyboard-and-Keypad/ta-p/3491341

    Shooting in the dark here as well, but I would start with just a moving average at first...

    You may have more luck with an RTD and something like this: http://sine.ni.com/nips/cds/view/p/lang/en/nid/201609 I agree the c-series options do not look like you'll get the rate you need. With a transmitter like ShaunR suggested, take note it's response rate and that some/most are not scaled to temperature, just the non-linear thermocouple signal is output.

    This should be a bold pop-up for the first 10 times anyone drops a vision VI. Image wires are references.

    Looking at the equations suggests to me that the issue is not the code, but the equations themselves. They rely on each other cyclically...
