  1. I'm guessing that this is a school work project. So, I am not giving you an answer, but I will try to lead you to one. If you want to break a beam and trigger on that, you will need several things: A beam, a beam receptor, and something that will be triggered. For the beam, I have used a laser diode (beam) and photovoltaic cell (receptor) with success before. You will notice a difference on the photovoltaic (solar cell) depending on the presence of the laser diode beam. As for the software, poll for the change and trigger your output (UI?) based on the "correct change". Let us know if y
  2. :!: Yes, but we will have to wait a year until LabVIEW is 21 years old to see LabVIEW 8.21
  3. Have you looked at the Simulate Arbitrary Signal Express VI? The UI in it does some cursor-drag-to-define-waveform stuff. It's built in. If it did a spline instead of just straightline interpolation (or choice of either) that would be cool. Maybe you could steal some of it. Hope that this helps, Bob Young

  5. I haven't done this in LabVIEW, but a quick google search turned up http://en.wikipedia.org/wiki/Round-robin_tournament and http://www.devenezia.com/javascript/articl...oundRobin3.html This seems to be a fairly good explanation and sould be easy to implement in LabVIEW (or with even less translation, a math script node). I might play with implementing it this weekend, but don't wait on me! :beer: Hope that this helps, Bob Young
  6. I have been unable to find the PDA 8.2 link. Could you please post it? I am not really sure it is out yet. Thanks, Bob Young
  7. Express VIs are to LabVIEW what crayons are to art; very few serious artists use them in their work but they get a lot of people to try their hand at art and a few people that try will become one of those serious artists. And those serious artists typically out grow crayons except where it really makes sense in their work. Just another medium for work that most of the beginners will start with and the pros will typically not use. As a pro, I use them but not very often and only when I know it is what I am really after. Elapsed time, DAQ assistant (as a starting point), Instrument assista
  8. On Monday, 31 July 2006 NI mistakenly released Download File:post-1172-1154382504.mp3 the attached podcast and a few hours later they replaced it with the one advertised on the NI podcast page (by Steve Rogers). Here is the mistaken one. Bob Young
  9. It is so hard to tell because I don't know what to count. If I used LabVIEW on one project 3 years ago, do I count as a user? If I am still using LabVIEW 5.1 today because the company does not see the need to upgrade, do I count? If I haven't purchased just LabVIEW in 5 years because I have an SSP subscription, do I count? It is all so grey! :question: Thanks, Bob Young
  10. The student edition is still under $100. Anyone who is interested in using LabVIEW for general hobbyist use can use the student edition and have most of the capability of the full package. This is what I recommend to anyone who expresses a non-business interest in LabVIEW. The LabVIEW 8.0 Student Edition is due out any day now. You can order it at Amazon or from NI itself. There is also the Lego NXT system do out late summer. All are great ways for someone to be introduced to Graphical Programming. Just a thought. Bob Young
  11. Actually, no. This forum is for more Advanced discussion. The discussion area for first timers and people who just need a little hand-holding (as we all do from time to time) is the Developer Zone on NI's official site. You could post your question Here or Here. If no one else answers first, someone from NI will answer in a day or two. This forum is called LabVIEW Advanced Virtual Architects becasue it is geared more to advanced topics. Design patterns, tricks, discovering and using undocumented features, large project challenges, and multiple developer challenges are the sorts of things
  12. That is true, but this processor can use several different OSes and if it is using one that the PDA module would work with, it would be much easier to program for. It would also be less deterministic and more costly per board. Off hand, I would like to throw out that embedded programming is an entirely different animal from Windows programming and using the PDA module is very much like windows programming. The embedded module is difficult to get used to if you are used to regular LabVIEW for Windows (or Mac or Linux). Programming for a particular processor that does not have a supporting
  13. The answer really depends on what OS if any you are running. If you are running Windows CE, you might want to try the LabVIEW PDA Module for PocketPC. I am not sure if Windows Mobile 5.0 or other PocketPC OS is available for this configuration, but if it is, the answer would be LabVIEW with the PDA module. There are some significant differences between Windows Mobile for the PocketPC and the more robust, more deterministic, and typically embedded Windows CE, but LabVIEW PDA module might work out for it as well or at least get you closer. If you are using Embedded Linux, some other OS, o
  14. I think that mid January would be good. University is still on break and the cold of the Northern areas could be broken by the welcoming mildness of Austin in January. Just a thought. Bob Young
