  1. Duplicate thread in the NI forums: http://forums.ni.com/t5/LabVIEW/Is-the-compilation-done-differently-on-Linux-than-on-Windows/m-p/3000819#U3000819
  2. Since you are talking about deterministic loops, they have to run at a certain rate. Therefore you will technically need a polling mechanism. What kind of data are you trying to transfer?
  3. You have to have an NI DAQ card. Something like the USB-6009 would likely work for you.
  4. The term "subVI" just screams that it is called by something. Would you rather call it "subroutine VI" (subVI for short )? I've never heard of there being a confusion with this term. I say educate those who are confused because by making up another term, you are going to just confuse the large majority who understand "subVI".
  5. You must have edited the PNG file directly while leaving all of the header data alone. When I copied that snippet to a blank VI, that TRUE constant wired to the conditional terminal became a FALSE.
  6. It was fun having her around. I'm glad to hear she had more fun than I thought. Yes, she must come next year.
  7. Do you have some code you can share so we can see how you have your task setup? In general, a buffer overflow is cause simply by not reading the data fast enough while in a continuous acquisition or by setting the buffer size (which will always be less than the default buffer size).
  8. Team up with Mark and do it. Just as long as you share your videos
  9. Since it currently looks like I won't be there on Thursday, go for Fab's presentation on Unit Testing.
  10. Was just trying to install a bunch of my favorite tools on a new computer last night. VIPM would not let me install the CCT because there was a conflict. Apparently, it conflicts with itself! VIPM 2014. Looking at my other systems who have upgraded to VIPM 2014 still has the CCT installed, but it is showing up as a conflict. Perhaps the conflicts with Code_Capture_Tool >= 0.0.1 should be removed from the package.
  11. Because I can't use it in my executables.
  12. The only bummer with this toolkit is that it requires a scripting node to get the picture's rectangle bounds. Maybe there's another property that could be used instead that doesn't require scripting?
  13. Congratulations. Hope to see you at the CLA Summit.
  14. Just quickly playing around with it, I like. I really like the linked thread feature where you can start a new thread based on a post. But we would never need that since we alway stay on topic...
  15. You could use the Write To Spreadsheet File. You may have to play with the Transpose? input. Personally, I just use the Configure Streaming function to stream the data to a TDMS file. I makes things really simple.
  16. I don't see why your UI loop would need to know the hardware state. If it doesn't get a message, it doesn't care. I find it is a lot better to keep things separated. Use the event to update your UI. Otherwise you will have to have your reading from the FPGA in the same VI as your UI to update your indicator. GUI VIs get large enough. I find it best to try to keep that as separate as you can. Even the large amount of data that I have passed around has yet to cause any issues.
  17. I was going to suggest using the Elasped Time express VI and only read the SQL data when "Time Elaspsed" (use a case structure). As Tim_S stated, use a small wait then.
  18. You have a data dependency between your two loops. Combine the loops into a single loop. You can have a counter keep track of your time to state when to toggle your LED.
  19. Do you have an example of your text file you can share? Do you have any code to show what you have tried?
  20. The answers should be in the back of the sample exam. If you have questions on why those are the answers, ask those.
  21. Do a search in the LabVIEW Example (Help->Find Examples) for Digital Output. You should find plenty of examples of how to control some digital IO.
  22. You will want to create some digital output tasks to control some of the DIO. Use the DIO to control your relays. You will very likely need a buffer circuit to supply enough current to control the relays.
  23. Anymore, I doubt it. When the In Place Element Structure was first made, it would tell the compiler to do things in place (no data copies). I believe the compiler has gotten a lot smarter since, so there likely isn't any difference anymore.
  24. It really depends on who did the presentation for when or if it will be posted. At least we have Mark's videos for some.
