  1. QUOTE (crelf @ Mar 20 2008, 08:07 PM) Me too disabled caps lock and remaped delete to one of the windows buttons on my hp notebook. Del is normally located in the upper right corner on the keyboard.
  2. QUOTE (Tomi Maila @ Mar 17 2008, 04:14 PM) Tomi I suspect it is either Finnish or Swedish cartoon board made of pine with slight mix of spruce... We have longer fibers in the north..
  3. QUOTE (alexadmin @ Mar 17 2008, 03:18 PM) Under numeric and datamanipulation you have type cast. Another option is byte array to string under the string palette in combination build array.
  4. QUOTE (neB @ Mar 17 2008, 03:15 PM) Thanks Ben, I have learned something new and important today. I have to investigate this because I will use a hub USB and two daqdevices and two usb232. Maybe a really good UPS is worth the cost.
  5. QUOTE (neB @ Mar 17 2008, 02:54 PM) Ben that was a good comment, I had some measurement eq. on a train and we had propblems with some usb devices. Do you mean that the computer itself would not be effected but usb-device would be?
  6. QUOTE (crelf @ Oct 10 2007, 09:07 PM) Well the same boxes this year too
  7. QUOTE (fuzzycontrolfreak @ Mar 17 2008, 01:41 PM) We have 6009 in a industry application that just stopped working, we were forced unconnect and reconnect the device before it started to work properly again. However since then it has worked, it worked for some month before. It all depends you need the reliablity? I would go for something with isolation, if you are going to have your own sensors, there are usb modules for 4-20 mA.

  9. QUOTE(bmoyer @ Mar 7 2008, 03:41 PM) Well you can you use linear algebra functions to a make line or a plane fit.
  10. QUOTE(tcplomp @ Feb 13 2008, 03:21 PM) A bit but not, but without the processing capacity.
  11. QUOTE(crelf @ Feb 13 2008, 05:17 AM) I would like to see a similar with network interface instead usb and unit with two slots.
  12. QUOTE(lraynal @ Feb 12 2008, 12:31 PM) For me as well!!
  13. Inspecting your graph would it not be more resonable to use a function that goes to constant when x goes to inf? Eg. a+b*tanh(c*t) or similar.
  14. I dont have Labview on this computer but is not there a VI for generating sine waves under the signalprocessing palette and the subpalette signalgeneration?

    Gps help

    QUOTE(anoop @ Dec 12 2007, 06:19 AM) From the example that NI gives, it is fairly simple to find the vi for choping up the NEMA-string, however it is not a RMC message they have done (if I remember correctly), it was some more general. I had another message type than the type made by NI and it took some 0,5-1h to convert to my message type. BR Anders
  16. Use the "ramp pattern.vi" to create your time sequence. The draw a for loop, place a sine.vi in for loop. Connect the ramp pattern output to the sine function and so on. or simply as figure 2 .Put a for loop after the sine calculations and put your indicator inside with an wait inside. BR Anders
  17. QUOTE(RovingCalypso @ Dec 14 2007, 09:28 AM) Here you have some hint for the calculation parts.http://lavag.org/old_files/monthly_12_2007/post-5713-1197653502.png' target="_blank"> BR Anders
  18. Make a arrray of RGB values choose value from them. Colorbrewer has alot of different color maps http://www.personal.psu.edu/cab38/ColorBre...er_updates.html for instance
  19. QUOTE(JFM @ Nov 11 2007, 03:34 PM) Thanks J, I will look into that I might not have discribed the problem the GPS gives ten values each second and I need to do down sampling to one second. Maybe I have done a problem of something that isnt, I only need to pick a message that is within that second, or the same fraction. BR Anders
  20. It would very useful to have small icons in the upper leftcorner to choose from for different types of VIs. It would be very good especially in a learning situation. I hope someone that has made a customized iconeditor adds this to their design.
  21. Dear all Have any of you written any code and could share some hints how to syncronize three different data sources, two of the can be made fairly in sync from the start (two daqmx units), but the third is a serial unit a fast GPS? The problem is the GPS sometimes lags behind some sec and therefore sometimes give two or more sets of position data (of course they are well time stamped as the data from the daqmx units). I actually have a fourth data source that uses seriel interface and give data only every minute but the with 15/32 sec resolution, but for the moment I will use the supplied instrument software. Sorry for asking a somewhat trivia question, but I stuck after thinking and analysis the problem and now I have to wrap-up things :thumbdown: Best regards Anders
  22. Break down your problems in subproblems and specify what your code should do in each case. Look for similar tasks and reuse code for similar tasks.
  23. QUOTE(kbersch @ Oct 30 2007, 11:19 PM) Nice Work!
  24. There is an example on reading NEMA183 from a GPS on NI-support pages. A complete set of VIs.
