  2. As of the latest Tools Network version, the palettes should also appear in the "Flatten/Unflatten String>>JSONtext" palette, in place of the install link in LabVIEW 2019. It's programmatically added, so let me know if that doesn't work for you.

    A LabVIEW programmable PLC for $99 + $59 per I/O module? This shouldn't be an April fool's joke
  6. Hi, Say, I am going to build a system and control it using labview through DAQ. For example, the system has stepper motors to move a heating chamber back and forth, a temperature monitoring system, a pressure controlling gauge etc. Now, before diving into building the actual system, Is it possible to make a simulation of the whole device and integrate the necessary LV coding, where I can show on screen how the LV program controls the different parts of the system?
  7. A few more April Fools of the past (and a fake fake one from 2019):
  8. Last week
  9. But surely all of these are slower and more memory wasteful than transposing which simply twiddles the order and offsets of the pointers that are used to index the block of memory in which the array resides?
  10. If you don't want to use a feedback node, another option is using a local variable (see example below) It sounds like you're trying to process losslessly. If that's the case, you usually need some sort of buffer. In this example, I use the event queue as my buffer.
  11. VITech will bring along this uniquely boxed Raspberry Pi. 😊 Completely ready to run LabVIEW programs out of the box.
  12. Nope. You may want to extend that courtesy but it isn't required for BSD.
  13. Ok, great. I guess we would need Ton's permission if we wanted to set up an online repo - GitHub for instance - for this package, right?
  14. I'm not a HID device expert (Rolfk maybe?), but there seems to be several DLL wrappers to talk to HID devices, but the best solution is to use NI-VISA and talk to it over USB Raw. For this you'll need to make your own INF driver using the NI-VISA Driver Wizard (should be installed with NI-VISA). Then install that driver for your device instead of the one from Microsoft (Device Manager). For this in Windows 8 and newer you'll need to disable driver verification. Then the device shows up in MAX, and the Help >> Find Examples and searching VISA Raw will show some examples. http://www.ni.com/tutorial/4478/en/ https://forums.ni.com/t5/LabVIEW/Nugget-1-of-n-GEtting-started-with-USB-communication-via-VISA/td-p/743518 https://forums.ni.com/t5/LabVIEW/Nugget-2-of-n-USB-Control-transfers-using-VISA/td-p/757011 If you can't or won't use VISA then there are lots of other DLL wrappers but I haven't found one that works as well as VISA with custom driver. http://ahidlib.com/pages/programming_labview.php?lang=en (license needed for full?) https://forums.ni.com/t5/Example-Programs/Windows-API-HID-Functions-Enumeration/ta-p/3513868 https://forums.ni.com/t5/LabVIEW/Confusion-between-HID-and-VISA-communication/m-p/1741390#M610130 https://forums.ni.com/t5/LabVIEW/Need-Example-Code-to-Interface-with-a-USB-HID-compliant-Device/m-p/2763516#M814451 https://forums.ni.com/t5/LabVIEW/How-to-configure-the-call-library-function-using-a-dll-for-HID/m-p/2757194#M813218 https://www-user.tu-chemnitz.de/~heha/mb-iwp/Durchflussmesser/
  15. It is open source. It is licensed under BSD, which in layman's terms means you can use it for personal or commercial use, and various attributes must remain in the source, and you can't sue the author (I am not a lawyer). I think the installed location is <user.lib>\_LAVA\VariantProbe
  16. My only other issue is, I am triggering my Latch reset with a falling edge trigger. The clock that is running the latch is only running at the speed of a while loop. It is causing me to miss the falling edge sometimes. Do you have any suggestions Thanks Setting the Feedback node like this to false did not work I need to find a way to guarantee it
  17. With A slight modification you can get the intended result: horizontal concenate.vi
  18. Hi there, Thanks So when i wrote the VI i notices it automatically populated a feedback node If i tried to delete it , i could not compile. So the feedback node is my answer but need to understand how to use it. I know my Q output to initialize to false and my Q not to be high I will read the link you sent me. Thank you
  19. Initialization behavior is well defined in the settings of the feedback node. https://zone.ni.com/reference/en-XX/help/371361L-01/lvconcepts/block_diagram_feedback/ I'm not sure what you mean by force. Are you trying to make it into a d latch?

    I'm an avid GoT fan, but I'm waiting for Season 8 to arrive..... 🤣
  21. Having trouble initializing a flip flop VI i wrote It starts up in whatever state it wants. How can i force a particular state? Its just an SR latch Thanks in advance

    If you happen to be a GoT fan, the finale is being screened at The North Door. After that, of course there is the meetup at Banger's.
  23. Would you consider making this open source?
  24. Hi, have you came across this one before? https://forums.ni.com/t5/Real-Time-Measurement-and/building-lvlibp-on-real-time-does-not-include-version/td-p/3926789 KR, Benjamin
  25. Great to see the LabVIEW wiki alive and kicking again! Hope to have a bit of time to contribute sometime after NIWeek...
