Image-aquisition with LabView2020 for Linux from a GigE Camera
ensegre replied to Yaw Mensah's topic in LabVIEW General
If the only way of commanding your camera is through the vendor sdk, bleh. As Rolf wrote, though YMMV. If by chance the camera is supported by v4l2, there you go; shameless self ad. -
NI abandons future LabVIEW NXG development
ensegre replied to Michael Aivaliotis's topic in Announcements
I see. Thanks Rolf. In fact I am so used to see Qt used by vanilla OSS, that I overlooked the issue of licensing. All technical potential showstoppers aside, in any case. -

Just spitballing without knowledge, but via anything modern like Qt perhaps? -
Assign Array numeric to an alphanumeric value (letter, string)
ensegre replied to Apolo's topic in LabVIEW General
To start with, you probably want to write your results into an array of strings, not of numbers. And anyway, what should be the purpose of the while loop and of the event structure with infinite timeout? -
alien --target=i386 is not it? (I forgot since last time)
-
Probably you shouldn't have. Forgot what I did then, but for me $ file /usr/local/JKI/VIPM/vipm /usr/local/JKI/VIPM/vipm: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.33, BuildID[sha1]=ff35d7adc7d9ef4e1ee0b41f6d67085e2c22dbe7, stripped $ file /usr/local/JKI/VIPM/support/*.so /usr/local/JKI/VIPM/support/lvanlys.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, stripped /usr/local/JKI/VIPM/support/lvzlib.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynam

I can build executables on my installations of 2018 and 2019 on Ubuntu, FWIW. Used alien as well (alien --install --scripts or something the like. Seem to remember also --target=i386 to force the installation of some component). Have not yet installed a 2020 so can't say, but is there chance that you skipped one rpm?

This one is simply great as a GUI for that. If you're looking for a programmatic way of monitoring running clones, I guess you simply have to look under the hood.

I found this one dated 2016: http://download.ni.com/cert/doc/NI PCIe-5140.pdf

If you'd like to give me a review on this... I actually never used it for anything serious, but it was working for me.

Right, if I put it there I get all the brown and light blue bonanza. I was mislead by http://zone.ni.com/reference/en-XX/help/371361B-01/lvconcepts/customizing_your_work_environment/#How_LabVIEW_Stores_Options which is pointed at https://labviewwiki.org/wiki/LabVIEW_configuration_file. But uh, that is the help page for 8.2. Still, it is at odd with https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000PA7rSAG&l=en-IL

I see, thx. Still don't think my LV19 can toggle it with Ctrl-shift-DH, nor I seem to be able to create the brown nodes (it's ~/.labviewrc), but whatever. i was just curious.... thx for the conversion.
-
I'm curious to see if that exists in linux too. LVdebugKeys=True + Ctrl-shift-D-H don't seem to apply. Could someone attach the snippet saved as VI for LV<=2019??

spitballing, having never worked on cRIO: standard linux ways like just parsing the output of free wouldn't help? Or reading /proc/meminfo?

Multi threaded telnet comms
ensegre replied to alecjcook's topic in Application Design & Architecture
Do you really need the whole power of telnet? Because if no commands are involved you can just tcp read/write, which I assume works multithreaded. At least that was the case the last time I had "telnet" devices to communicate with. ...Have you seen this thread? -
The DSC module has a few of them, but alas, you can easily create better custom boolean controls yourself Here is an example of mine. The pipes, the pump PP1 and and all the valves come from DSC, almost all the rest are customized controls.
-
IIUC the OP, he wants to click on a particular area of the plot (needs a mouse Event on the graph control, and identifying the coordinates) and then popup something (Show FP of another vi). My guess at least.
