Time controlled Loop faster than 1ms

HI
I work with Labview 8.2.1.
I need a time controlled loop who is faster than 1ms. I tried to use the 1MHZ time source (see picture) but the loop does not work with this.
Please help

There is no picture to see...
Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T

  • Time Controlled Loop?

    I am building an application that scrolls through an panoraminc photo to make it appear as if its rotating 360 degrees.
    So far i can get the image to scroll left and right continously by having a left and right button to click on
    what i am after is some ideas/direction on how i could automate the process, as in when you click the left button the image will scroll at a certain speed.
    I was thinking that i would need a time controlled loop where the the method for scrolling the image to the left occurs every few seconds.
    Thanks in advanced

    Use a inner class that extends Thread as follow:
    class MyTimer extends Thread{
    boolean continue=true;
    public void stopScroll(){
    continue=false;
    public void run(){
    while(continue){
    try{
    xpos=pictureScroll(img, xpos, "right");
    sleep(100);
    }catch(InterrupdedException e){
    }use
    Thread t=new MyTimer ();
    t.start();to start scroll, and to stop
    t.stopScroll();in button's ActionPerformed

  • Make pictures loop faster than music on menu

    On the menu of a dvd I'm making, I have a one and a half minute song and pictures that loop in the background. However, the theme I'm using ("Modern") only allows me to use a maximum of three pictures, and because of the length of the song, each picture lasts thirty seconds, which is much too long. So what I'd like to do is either add more drop zones (this would be ideal, but I don't know if it's possible), or make the pictures loop faster than the music.
    If either of these is possible (preferably the first), I'd love to know how.

    Sorry, it is what it is.

  • Wrong Time -- 3 mins faster than my iMac

    Both my iPad and my newest generation touch are several minutes faster than the iMac they sync with. My nano is is w/in seconds, so that works fine.

    Don't know about the iPad, but AFAICT, the current iPod Touch DOES NOT TIME SYNC with either a desktop computer or over Wi-Fi. While this is absolutely absurd, as 1st generation Palms 15 years ago could sync the clock , the new iPod Touch does not. You can only change time manually and then only to the nearest minute; there is no way I know of to set it to the second.
    What's worse, despite hours of looking, I can't find an AppStore app that will perform a time sync either. I think Apple refuses to allow a developer access to the internal clock.
    I hope someone proves me wrong, but unless Apple fixes this problem or allows others to do it, we will be without this very basic function.

  • Faster than milisecond

    I would like to generate a diferent wave function every 10 ns and sent it to a function generatot at the same frequency. There is any possibility to make LabView faster than 1ms? I will appreciate any sugestion.

    LabVIEW is much faster than 1ms, but software timing is limited to 1-2ms. Even that cannot be guaranteed on a multipurpose OS. For deterministic timing, you need to utilize hardware timing of your DAQ hardware or use LabVIEW RT of FPGA, for example.
    10ns is awfully fast. What kind of function generator do you have and how do you communicate with it? How many points are in each 10ns chunk of waveform? Is this microwave? How many different functions do you have? Is there a repeating pattern?
    Can you provide a bit more details on what you are actually trying to do? Seems quite unrealsistic.
    LabVIEW Champion . Do more with less code and in less time .

  • I am using a timed while loop and am unable to get the loop to run at a speed of less than 1ms (I am currently using the Wait(ms) function). How can I get a faster response?

    I am trying to create a virtual engine within a timed while loop and am unable to get the loop to run at a speed of less than 1ms (I am currently using the Wait(ms) function). This does not however allow realistic engine speeds. How can I overcome this? I have access to a PCI-MIO-16E-4 board.

    Andy,
    Unless you use a real time platform, getting extactly 1 ms loop rate
    (or even less) is impossible. It starts getting troublesome at about
    0.1 Hz for standard operating systems.
    I'd tackle your problem with "if i mod 10 == 0 then sleep 1 ms".
    Of
    course this is jerky by design.

  • Can I get better time resolution than 1ms in labview?

    Hello,
    I am trying to generate an external waveform which requires timing to be in the microsecond range, I was trying to use the wait function to define the timing dt but found that I could not get below 1 ms. I tried to specify timing in the microsecod range by overloading the wait function with a float (0.200) to represent 200 us but found behavior to be erratic. Again, I am trying to create a waveform for extenal hardware which does not support buffering and requires software to drive.
    Thanks!
    Joel Abdullah

    "I am trying to create a waveform for extenal hardware which does not support buffering and requires software to drive."
    Sorry but that simply can not be done in a Windows environment due to the limitaions of the OS (1KHz was "way-fast" when WIndows replaced DOS).
    It can be done in a Real-Time OS like Pharlap for example.
    Attempts to deterministically perform any operation at a rate faster than 1KHz in a non-deterministic OS can be best described as an "exercise in futility."
    Trying to help,
    Ben
    Note to Waldermar:
    Timed loops can perform rather well at 1KHz or even better if you have a hardware clock available.

  • Loop rate on my RT system not faster than 1kHz

    Hi,
    I have a PXI5404 frequency generator card without memory. So I tried to
    program the memory list on my own with  while-loop. The value for
    the frequency card is updated with an extern digital signal. But it
    sems that my loop doesn't run faster thn 1ms. Is there any solution?
     I have a PXI system with an PXI 8176 Controller, an 6259 M-series card, a PXI 6723 analog out card and the frequency card.
    Thanks for your help

    Thanks for the answer.
    In deed, I was able to change my frequency faster, down to 200 microseconds. First I gave out a frequency of 20kHz, switched to 3 MHz for 200 µs and back to 20 kHz. So, the card can read the frequency faster, but after I switched back to 20 kHz, the frequency isn't updated any more. The card is missing one trigger. Could it be faster to communicate directly with the analog devices chip un the card via some hardware addresses?
    Thanks

  • Playback speed in Sample Editor window many, many times faster than track (at correct speed) in arrange area. How do I sync Sample Editor playback speed to correct speed/tempo in arrange area? Track is spoken word.

    Playback speed in Sample Editor window many, many times faster than track (at correct speed) in arrange area. How do I sync Sample Editor playback speed to correct speed/tempo in arrange area? Track is spoken word. Sample Editor playback sounds like Alvin on a meth binge. Spoken phrase is generated from Textspeech. Textspeech can export files as WAV files or MP3 files. Perhaps a clue?:   When exported Textspeech WAV file is dragged and dropped into track in arrange area of new project, it exhibits same supersonic speed. When Textspeech file is exported as MP3 file and dragged and dropped in arrange area track, it plays at correct speed.

    Thanks Erik,
    If nothing else, this huge list of updates and fixes, shows clearly that the Logic Dev team is working hard on fixing and improving LPX to a major degree.... and from the list of fixes done.. show they do read the bug reports submitted!
    As an aside....
    I recall how all the 'naysayers' prior to LPX (and in some cases, since...)  were proclaiming how Logic was dead, the team was being disbanded, we won't see any further development, the Dev team doesn't listen or care... and so on....... I wonder where those people are now?

  • I want to add more capacity on hard drive of time capsule. Can i add a normal usb driver? I will see it as an external drive in the time capsule network? It will work as fast than time capsule? Thanks

    I want to add more capacity on hard drive of time capsule. Can i add a normal usb driver? I will see it as an external drive in the time capsule network? It will work as fast than time capsule? Thanks

    Can i add a normal usb driver?
    Yes, but be sure that the drive is formatted correctly for Mac in Mac OS Extended (Journaled)
    I will see it as an external drive in the time capsule network?
    The drive will appear as a shared network drive, like the Time Capsule.
    It will work as fast than time capsule?
    No, the drive will operate at about half or 50% of the speed of the Time Capsule.

  • Mencoder H.264 20 times faster than Compressor 2

    I tested mencoder with compressor running with 5 G5s. the H.264 implementation of mencoder was four times faster than the 5 dual core quads clustered with compressor two and queermaster . my single computer alone with just a dual 2 ghz processor encoded a movie 20 times faster than compressor with Queerrmaster on this same machine.
    compressor costs more than mencoder(free in DVision). to get compressor you have to get an expensive Pro app.
    What's wrong with this picture?

    Well, I have heard this lament before with the G5s, and all I can say is that I guess Apple is slowly starting to drop support for the PowerPC generation (it was inevitable). I assume you've upgraded to 3.0.1?
    As for Motion 3 (and someone correct me here if I am wrong), I believe it's slower because of the full 3D integration. Whether or not you have a lot of 3D aspects, I think it still calculates for it, causing your response and render time to decrease.

  • Web Report - ABAP Vs JAVA engine - ABAP 10 times faster than JAVA

    Guys,
    I want to share what we found in our project and see if any of you have insights
    into our findings.We are on NW2004S SP14 and we are moving to SP15 in a couple of weeks.We created query, developed WAD for it and executing the WAD takes for this query takes 22 secs (Vs 2 secs using ABAP) the query output has 1 million records and most of the actions we take from that point on like right click on account takes 20 secs (Vs 0 secs/instant using ABAP) , drilldown to level 4 of account hierarchy takes 58 secs (Vs 5 secs using ABAP), drilldown on cost center level 6 takes 42 secs (Vs 4 secs using ABAP), , right click on cost center takes 32 secs (Vs 3 secs using ABAP), ..etc.
    Basically every action we take in the JAVA report takes an average of  28 secs.There are 9 aggregates built on the cube that are barely hit by this query but the same query performing same actions with same selections hit the aggregates many many times.The questions I have is why is ABAP so fast compared to JAVA ? What is true explanation behind this behavior ? What are the dis-advantages by using ABAP engine ? Users are loving the performance and features of ABAP while they weren't really on board with the original JAVA report (as it was slow). ABAP is sure enough 10 times faster than JAVA. Query/Query Properties are exactly the same in ABAP and JAVA.Please explain.
    Cheers

    Hi All,
    Thanks to all you for your responses. I appreciate your time for going through my questions and coming forward to express your views.
    However, I was looking for more specific "factual" answers. My question is "What does a client miss if they opt to install only ABAP based BI 7.0, as against JAVA Based BI 7.0"
    thanks again.

  • "tp import all" runs 24 times faster than "tp import TR "  for long queue?

    After a test upgrade to ECC 6.0, I processed 1200 individual transports in 12 hours. When I rebuilt the queue of 1200 transports and processed "tp import all", it completed in 30 minutes.
    Should I expect "tp import all" to process 24 times faster than individual imports?
    800 transports were client independent (code) and 400 transports were client-specific (configuration).
    What run times have you seen?
    What problems with "tp import all" have you seen?
    Best regards,
    Gary Sherwood

    Hi Gary
    You don't know the 800 transports which are wating for the import, what could be render your system in case of import all. so, that's why , i will prefer to you import individual request instead of import all.
    offcourse, Import all are faster than the individual because it prepare all steps once to start import,

  • Unable to bootup after Yosemite install. have to keep shutting down from rear button. it does come on after a few times but then hangs at user login again. If you get in it is great. Seems faster than Mavericks but there is some sort of issue, bouts

    unable to bootup after Yosemite install. have to keep shutting down from rear button. it does come on after a few times but then hangs at user login again. If you get in it is great. Seems faster than Mavericks but there is some sort of issue, bootup /login.

    Knock on wood, this seems to have been my problem as well.  I stumbled on this thread after dealing with this ridiculously-long boot times for the past several weeks.
    I just reinstalled McAfee Antivirus and my Macbook Air booted up in less than 1 minute.  No more hanging on the boot-up progress bar.  No more hanging after I click on my user's avatar on the log-in screen.  Bootup would often take 5+ minutes and sometimes never complete.
    This has been SUPREMELY frustrating.
    THANK YOU SO MUCH FOR POSTING YOUR RESPONSE!!!

  • The time on my pre is faster than normal

    when i used the pre in my hometown the time worked fine. i am now at college and still in the same time zone so it is the same exact time as my hometown, but for some reason it runs faster than normal. so ill set it to my computer time then later on in the day it will be like an hour ahead. i dont know what to do, help please.
    Post relates to: Pre p100eww (Sprint)

    I've been having a similar problem. Here's my story:
    My wife and I got Pres on the day they went on sale. About a week later I noticed that the time was fast on both of them.
    Over the next few weeks I tried experimenting with everything I could think of. I tried every combination of setting the network time and zone sliders to on and off, but they still gained about 3 minutes a day.
    At one point I called Sprint. They quickly elevated me to the senior tech person, who was stumped. The best they could offer was to do a reset. Doing so did result in the phone grabbing the correct time, but it proved to be a non-fix... it started running fast again.
    In June we spent five days in Las Vegas. During that period, my phone kept absolutely perfect time; my wife's, however, continued to run fast. When we returned home to Seattle, my phone also resumed running fast.
    Last Friday we took the phones into a Sprint store with an on-site repair shop. They took mine in the back, told me they did some updates (not sure what this was since all my updates were current) and told me it was fine. No such luck. By the next day I noticed it was still running fast. My wife's phone also had some minor screen cracks so they swapped hers for a referb unit. Believe it or not, this one started running fast as well.
    At some point I noticed that the phone grabs the correct time if I connect it via USB for a media sync.
    So, that's where I'm at -- we've handled three phones and all of them run fast regardless of how the network/zone sliders are set. I really don't know what else to try but would eagerly welcome any suggestions.
