  1. Taylorh140's result is correct. He was talking about SGL values. When you're using a 32-bit SGL, 1.4013E-45 is the smallest possible positive value. In other words, 1.4013E-45 is the next SGL value after 0. When you're using a 64-bit DBL, 4.94066E-324 is the smallest possible positive value.
  2. I don't know if this is related to your issue or not, but there are known problems with some brand new AMD Ryzen CPUs: https://arstechnica.com/gadgets/2019/10/how-a-months-old-amd-microcode-bug-destroyed-my-weekend/ See if updating your BIOS helps at all. (Even if it doesn't solve this problem, I'd imagine you want a functional RNG on your PC!)
  3. Judging by your screenshots, there is a problem with the DNS server that your Chrome and Firefox are trying to use. IT might have configured your Internet Explorer's DNS settings differently. I recommend asking IT for help -- describe your issue to them and show them your screenshots. Mention that the DNS server works reliably for Internet Explorer but not for Chrome/Firefox. (I'll qualify my previous question: "What happens if you try on a different computer that is not managed by your IT department?")
  4. LAVA opens fine for me in Edge 80.0, Chrome 80.0, and Firefox 74.0. What happens if you try on a different computer? What happens if you try in Incognito/Private mode?
  5. I don't know if a "proper" way exists, hence https://forums.ni.com/t5/NI-Package-Management-Idea/Add-ability-to-reclaim-space-taken-by-cached-packages/idi-p/4024241 I've been manually deleting the *.nipkg files, and the very old folders in C:\ProgramData\National Instruments\Update Service\Installers, without ill effects to my day-to-day work. I think NI Package Builder or LabVIEW Application Builder can't bundle a dependency if its package or local installer is gone, however.
  6. You mean like how a Java compiler prepares only small chunks of code linked together by the JVM?
  7. I don't understand: Doesn't your test software need to be validated too? And IKVM.NET is a generic wrapper of Java in .NET -- it is not a direct interface for the Bluetooth driver. Why won't this need to be validated? In any case, someone else forked IKVM: https://www.windwardstudios.com/blog/ikvm-is-alive-well
  8. There are some examples online about using CANopen in LabVIEW: https://forums.ni.com/t5/Example-Code/CANopen-Reference-Example-for-the-NI-9853-C-Series-CAN-Module/ta-p/3996129?profile.language=en
  9. Your last FFT image shows that most of the noise content is in 50 Hz and its harmonics. I'm guessing that you live in a country with 50 Hz mains power, and the electromagnetic radiation is being picked up by your system. You wrote that the system "gives noisy reading even if bias resistors are used" -- Why would you expect the bias resistors to reduce noise? If anything, those long, unshielded resistor leads make them even more sensitive to radiation. Ways to reduce electromagnetic interference include: Using shielded and/or twisted-pair cables. Using shorter cables. Checking your grounding. Your first plot shows huge voltage drops from 1.25 V down to 0.2 V. I'm guessing you have a group loop or short-circuit somewhere in your system when your laptop's power adapter is connected.
  10. Raspberry Pi and BeagleBone are full-fledged Linux computers. Arduino is a microcontroller. Compare their specifications and I/O to see which one meets your requirements. See also https://forums.ni.com/t5/NI-Blog/LabVIEW-Community-Edition/ba-p/3970512, especially the part about "Hobbyist Hardware".
  11. Interesting. Looks like there's some type propagation issue when the Decimal String to Number node is combined with the Negate node: Remove the Negate node and the problem disappears. The issue seems to exist in the LV 2020 beta too. Would you like to post in the beta forum, for the attention of NI R&D enginners? http://www.ni.com/support/beta-program/ (I'm happy to post on your behalf, if you prefer)
  12. There are multiple demonstrations in the wild about using WebSocket with LabVIEW. Google should be able to help you. Here is one endorsed by NI: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000kJV5SAM @smarlow has not posted in over a year, but might be lurking: https://lavag.org/profile/17965-smarlow/
  13. Jim does not come to LAVAG often (e.g. see https://lavag.org/topic/21017-where-are-openg-product-pages-for-packages/?do=findComment&comment=129287 ) I'd imagine you'd get a lot more interest if you post at the JKI forums Nested malleables + VIPC is not a combo that I use
  14. LabVIEW NXG uses UTF-8 for all text strings. I think classic LabVIEW (version 20xx) will unlikely ever get full Unicode support.
  15. Oops, I just realized: We can't use strcpy() because that would also try to copy the terminating null byte. Use memcpy() instead. (Sorry, my C is rusty)
