  1. Will There be a LAVA Salt Lick Gathering for 2008?

    in NIWeek

    What's NI-Week without the LAVA BBQ?!?

    Glad to hear you're enthusiastic :) Yes, there will be a LAVA BBQ - we're currently negotiating the finer details - look for a notice later this week...

    :thumbup: EXCELLENT! This will be my first NI week and I am really looking forward to it.

  3. LabVIEW based Soccer Robot

    :thumbup:

    Source: Apple Hot News Last year, just three and already competing at the world-class level, DARwin wowed crowds with his strength and on-field acrobatics. The youngster plays soccer for TEAM SPRInt, the first US team to qualify for the RoboCup, a global competition where soccer-playing robots vie for the world title. And, with the help of their Macs, the Virginia Tech team plans to send DARwin back to the 2008 RoboCup in China. Read more…

    When you say make your code respond faster what sort of time scale are you talking about? The response time lag and frequency of response that you are needing change the answer (at least in my mind).

    Also, can you post your code? Easier to offer comments if we can see it.

    OK, I followed the instructions posted by Jim (thanks Jim) for a "lone gunman" developer and got my repository started on my local drive, added in my project and then began adding in folders and separate VIs.

    I am interested in reading the thread you mentioned. I can't seem to find the thread with search. Can someone please post a link to it?

    Thanks

  8. Programamtically editing typedef enum or ring strings and values

    in VI Scripting

    Excellent! Thanks Ton. I'll use that. :worship:

    Good point Ton!

    Provided you don't have to change the enums at run time (which you can't in an active VI) you can define values of a ring and then replace the ring with an enum. Provided the enum does not end up being sparse (not all values defined) this makes it much easier to define all of the enum values.

    Ben

    I don't have to change them at run time. They just keep adding commands and I was using a ring control since the values related to the numbers are literal scattered about an 8-bit number space. Unfortunately, that required me to update every constant instance by hand everytime I got a change request. Need to use a more scalable type.

    Thanks guys.

    that' correct. i think 8 is for U8, please try it out.

    and Ben, the fame does not belong to me! i just remembered, that i asked this question in Q4/2005, too, here in the forum. it was answered by one of the "big old ones" in this forum. unfortunately I could not find the old thread any more and could not remember the name of my saviour, so I posted this example ...

    Now how does one summon the great old ones?.... I am trying to programmatically define an enum to use in a type def (the electrical guy keeps adding commands) and I was trying to implement the script show in this thread. The problem I am having is that I cannot find the "Rep" property of the enum class. Does it still exist? Do I actually need it?

  12. Standalone Stepper controller

    in Hardware

    Posted

    QUOTE (BrianJensen @ May 8 2008, 12:49 AM)

    In basics, I need a few outputs to drive a stepper driver, and a few inputs to read some switches.

    The tricky bit is that it need to be stand alone, that is, sort of mobile, and no need to be connected to a pc to make it run.

    Can I do something like this on a FPGA ? (I have no experience with FPGA at all)

    What would be the most cost efficient way to do a labview device that will live by itself. Can it be done at all, or should I start look at some other alternatives instead.

    Depending on the complexity of your test and the required data collection an FPGA could do it. On thing you should do is gather your requirements (data rates, motor charactistics, reporting criteria, desired cost range, etc.) and give a phone call to your NI rep. They are usually pretty good on suggesting options.

    To be a small portable solution you are probably looking (like the previous posters said) at a compact RIO based system. Once you get it programed and "set free" as I like to think of it, no computer is necessarily required. You could even use the LEDs on a NI9474 to display go-no go type results.

    Hope this helps,

  13. Lurker Roll Call

    Posted

    Guess I'll will de-lurk fully. :ninja: => :D

    I am Jason Willis. I work for BEI Precision System & Space Inc. (mostly) Primarily with test system development though I am presently working on a manufacturing system. I started reading LAVAG after I took the LabVIEW Intermediate classes last fall. The teacher suggested as a good resource and I admit it has been good.

    I have learned alot just reading through posts and solved more than one issue simply by using the search function.

    Oh, and I got my CLD just last month. Next up the CLA. :)

    That's me in a nutshell.

  14. Why I do what I do for the LabVIEW community.

    Am I missing something? I didn't see the link to the 42 min video?

    As for the more TV/less TV, it seems to be a rather basic concept if you boil it down. A participant will always add more than a spectator. To me its no different than saying if more people farmed there would be more food available. The underlying concept is almost a tautology to me.

    You know, I actually thought of a few smartarse comebacks, but that one dawned on me as I was about to hit send :) My work here is done.

    Got to admit the auto-response bot cracked me up. Of course I responded to up my count mostly.

  20. Programatic control of the Context Help Window

    in Development Environment (IDE)

    Posted

    I know you can use a property node to update a VI's description block, the content of which does appear in the Context Help window. You could simply read the help file into the program and pass it to description. That would be the only way I can think of to do it. Though could to think of it you can add help file links to a VI using the help tag and help path windows on the VI documentation window. These can also be updated via a property node programmatically.

    I hope this helps.
