  1. QUOTE (Minh Pham @ Sep 30 2008, 01:18 AM) I think having right click menu on the controls would be useful, having a selection 2 control on row, 3 controls of a row,7 controls on a row and the same for columns.
  2. QUOTE (Jim Kring @ Sep 29 2008, 06:49 AM) Well you should not be afraid of the socialization of banks, they will be sold to private owners for sure. When all mess is cleaned up. Ten years ago we had the similar problem in Sweden however the scale was much smaller of course. http://www.riksbank.se/templates/speech.aspx?id=1722
  3. From my perspective it would also be interesting to know if it would work to build on a XP or Vistas machine and transfer for Xpe.
  4. QUOTE (schneidley @ Sep 23 2008, 10:35 PM) Change voltage? well then it is anologue output.. A digital output is either on or off, it has fixed voltagelevels when its on or off. Have you tried to put all DO-ports to true respectively false? Then you should see something. Look at the examples within help labview for your hardware to get more leads. Those connectors on 6008 can be hard to measure on without using some wires.
  5. Now I have check the mathscript node and it also gives wrong results... I conclude that the mathscript node is not matlab compatible for basic trigometric calculations, octave does this better than Labview...
  6. QUOTE (Scott Carlson @ Sep 16 2008, 10:09 PM) I have you used they "old" shift registers my impression is that these are hard to read because of the backflowing wires. So I agree.
  7. Brian Ihope you are not using the same code for the math scripts, because it would indeed give strange results when moving code from matlab to the math script. Matlab handles large arguments well. How does other major program languges handle this case with large arguments to sine functions?
  8. QUOTE (LV_FPGA_SE @ Sep 14 2008, 04:50 AM) Devcon from microsoft seem to be useful, see this http://www.tomshardware.co.uk/forum/29642-...rive-just-click
  9. QUOTE (Phantom_Lord @ Sep 16 2008, 07:21 PM) It is the first time I have seen the use of feedback for implementing a circular buffer.
  10. QUOTE (jdunham @ Sep 16 2008, 05:10 PM) It would be ok if the output adapted to the format constant when VI is run. Then it should not show dbl as the datatype, it should show generic or similar.
  11. QUOTE (Phantom_Lord @ Sep 15 2008, 10:47 PM) Well you have this Vi that uses waveform input and not Dynamical inputs which expressvis do. http://lavag.org/old_files/monthly_09_2008/post-5713-1221561700.jpg' target="_blank">
  12. QUOTE (Phantom_Lord @ Sep 15 2008, 07:19 PM) Under Signal processing there VIs for FFT and Powerspectra that uses doubles as input. On thing you need to do is make the frequency axis.
  13. If you have full development or prof. dev Labview, then you have a ramp vi under signal processing and signal generation.
  14. Dear all Sin and cos functions gives non bound values if the argument is large than 9.2e18 then it will output a value in the same region. This could introduce large error if labview would be used for certain simulations. I also note the there is not a word in the help text about this. I have tested it in both 7.1.1 and 8.5.1. I hope it doesnt work this way in 8.6.
  15. QUOTE (Harshvardhan @ Aug 27 2008, 02:07 PM) If you have Labview installed on computer just place the VI in the startup under programs folder. There is instructions on NIs site how to make an VI into an windows service.
  16. QUOTE (neB @ Aug 27 2008, 02:48 PM) I would agree on the value if you could select the previously used tags (or even get suggestion on the right tag), but without streamlineing tags it is no better then a regular search on posts. The clouds in their current state is just clutter, it is stone age pressentation style. Any real clusters are pushed appart or togheter by the length of the tag. I have used some search engine that produced 3d clouds that with points in color and mouse-over labels, when I did it last I had a pentium computer and it was slow. I can find that search engine now.. My opion is that decluttering that taging is meant achived can be achived by other more efficent means.
  17. Why have a taging system at all it doesnt give any added value? For instance it makes the posts longer and therefore takes more time to read.
  18. QUOTE (Ton @ Aug 22 2008, 09:05 AM) On serialadapters female-female or male-male you have similar screws also on some scsi connectors.
  19. QUOTE (vidur moudgil @ Aug 20 2008, 02:20 PM) A tab control maybe useful, one tab or each case.
  20. Well Kenny G maybe an option or Warren G with especially Regulate when coding some control algorithm..
  21. QUOTE (zorro @ Aug 7 2008, 10:08 PM) My answers above.
  22. QUOTE (AnalogKid2DigitalMan @ Aug 7 2008, 05:11 PM) If it get better ungrounded an EMI-filter maybe worth considering.
  23. QUOTE (Dan Bookwalter @ Aug 6 2008, 10:34 PM) EMI filter for three phase are not that expensive if I remember correctly and they can be connected in two different way, have I been toold from an electricant. He told also me anecodote that in one mill he worked in they had 400Vs in reinforcement of the concrete, it was pure luck that they noticed that wall was hot. This caused by by slopy 3 phase wiring. It is an idea worth looking up I belive. I have also had these problems and using different power supply lines for the measurement equipment and amp maybe a good idea, althought it is against what you normally get recommended. Do you have any other machines that use inverters on the same prower line?
  24. Search examples and you will find output examples you daqmx.
