Time sync visa input with acquired sound data

Hello all!
I'm pretty new to LV, but here goes:
I'm trying to collect data from a balance via VISA read (RS232), and at the same time I acquire sound via the pc sound card. I'm looking for a way to syncronise the time for the two datasets (resolution approx. 0.1 s).
During test (flicking the balance with a small spoon), my results so far indicates a offset by 0.3 s, where the sound spectrum changes before the weight increase. This is not due to any delay from the balance, as it seems to react immidiately.
I would like to be able to use the same reference clock to the two samplesets, but I'm having trouble to understand the way that "Acquire Sound.vi" works regarding recording time data.
Any good ideas for a way forward ?

Can you post your VIs. The thumb rule then asking for help in this forum. Is to post the VIs in question at the same time. Much more easy to get grasp of the problem that way. And most of us will require a VI before we help anyway. The last tip. Never post a picture of the code, as we can not debug a picture
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

    Sorry to dig this out, but i just ran exactly into the same problem using a 7600GT. Reverting the appropriate libraries to 9.2.4 lead to a segfault in Compiz, deleting the libvdpau_nouveau files, however worked perfectly - thanks cro for the hint. But I guess, this is not a permanent solution, is there a better way to fix it? Maybe a bug report mentioning the problem would be of some use?

  • Acquire sound data time does not match with the waveform graph

    i am doing a basic data logging system to see the frequency behavior of sound. What I did is to use the "acquire sound" system of Labview and connect a waveform graph to see the time-domain behavior of sound.
    However, if I input a duration of 4 seconds (or any time), I will only see 75% of the sound (that is 3 seconds). I tried to extract the values using write to file to see if the waveform graph is the one who have the delay. however, the data also showed me 3seconds.
    I will attach here the picture of the simple program i created.
    I hope someone can explain to me why this happen.
    I am using the soundcard and microphone of a laptop. I also tried using a computer microphone. I have tried this program to all computers I can use (2 laptops: SAMSUNG, ASUS, and one desktop computer core i5)

    Hi all,
    have you find a fix for this issue? Im facing the same situation, using Complex type, and String data type both in the service and Bi publisher. We are consuming CC&B services, and we have noticed this error appears when BIPublisher is running on WebLogic (10.3) but it does not appear when BIPublisher is running on OC4J , of course running the same report on both application servers.
    Any idea?
    Thanks a lot, regards

  • Extremely slow sync for iPhone4 with up-to-date iOS

    Windows XP, plenty of memory, all itunes and iphone software up-to-date. Sudden decline in syncing speed has become rediculous. It takes 60 plus hours to sync music of 27GB. If a reinstall causes an automatic sync, I lose my access to all the content of my phone nearly instantly, and have to reset, and resync full conent. CRAZY!  I may switch to Galaxy phones if this keeps up.
    Please help. I am not syncing photos, calenders are not a problem, contacts seem to duplicate occasionally without predictability.

    The most likely explanation is that iPhoto is recreating the Photo cache for the phone. It only sync images optimised for the phone screen.

    Anyone have answers? Don't think it's related to wifi as worked perfectly fine on old iPad (ios7) and works fine with windows laptop via airplay in iTunes.

    Also here's the log before it happened. As you can see there is no activity from 9:48 to 10:00 am when the sound occurred.

  • Cannot change or delete a Visit List with old execution date

    Hi all.
    I'm creating a FM that updates Visit List.
    Its works ok while the "execution date" field in the VL its bigger than today's date.
    I cannot even change or delete it through /DSD/VC_VL.
    When I try to delete or change the VL I got this message Visit list 9XXXXXXXXX cannot be changed (execution date is before today's date).
    And when I try to change the header, all the fields are grey.
    Any ideas?
    Thanks.

  • Syncing my iPhone with Outlook

    I have now lost my contacts for a 3rd time syncing my iphone with my laptop. I did so in order to get the 4.2 update for it and to attempt to save my hard fought business and family contacts.
    I don't know if this is an issue to do with using Microsoft software with an Apple product, but as a consumer - I just don't give a ****. At this stage in the game, the two should be able to play nice and keep your issues in the courts and away from my data. Here is another suggestion - use the write terms to describe what is being done. Example - merge. Here is the definition of the word merge:
    merge – verb (used with object)
    1.to cause to combine or coalesce; unite.
    2.to combine, blend, or unite gradually so as to blur the individuality or individual identity of: They voted to merge the two branch offices into a single unit.
    –verb (used without object)
    3.to become combined, united, swallowed up, or absorbed; lose identity by uniting or blending (often fol. by in or into ): This stream merges into the river up ahead.
    4.to combine or unite into a single enterprise, organization, body, etc.: The two firms merged last year.
    Nowhere in this definition does it say that at the end of the merging - you should have less, certainly not significantly less than when the process started. I would expect duplications, I would also expect error messages as in the old mail merge process of Word 5.0 where you would lose data if a tab or comma was missing. But at the end of this merge in iTunes, the result is always some random loss of data that is impossible to establish any kind of rules. Did I lose the data because there was a duplicate on my laptop, because the fields were different? Why would I start with 600 contacts in my phone, 100 on my laptop - merge the two and end up with 90? Please someone explain how a merge could result in less, significantly less? How is that 600 + 90 = 120? ***!!!! I can live with the iphone not having java - I can just avoid videos, but now it can't add?
    Bottom line, can you please put your R & D department, your developers and engineers together and give them a basic vocabulary lesson. Merge means add - not subtract. Obviously this is an issue that has befuddled many before me and will continue to frustrate many more because is yet to be answered on this forum.

    I had a backup from outlook that I restored to outlook and then used Itunes to sync the Iphone
    I had to turn off the ICloud sync
    The only problem now is that it does not sync my calendar or contacts unless i plug the phone into my compluter and tell Itunes to sync them

  • IPod Touch will not Sync or restore with iTunes.

    I got an iPod Touch 64G on 31/12/09. Since then I've had a very difficult time syncing the iPod with iTunes. I installed iTunes on a Dell Studio 1557 i7 720, 1.60Ghz, 4G DDR3 1067 RAM, 500G HDD, Windows 7 Ultimate 64 bit. When I try to sync the ipod it gives me 3 errors The iPod "Tom's iPod Touch" cannot be synced.(X3) The required file cannot be found, An unkown error occurred (-48), and An unknown error occurred (-6999). I have made sure all my drivers on the computer are up to date. I have uninstalled and reinstalled iTunes. I've tired restarting the ipod. I've fully restored my ipod touch. None of these have fixed the issue. I get the same errors. Since I've had the ipod I've only been able to sync it 3 times, and the sync just started working by trying different things, like disconnecting and reconnecting the ipod, or switching to one of the other usb ports, but these little tricks only worked once. At this point the last failed sync has caused my ipod to only play one song and then stop playing, and many of the apps just crash. Syncing the ipod fixed this problem the one time it happend before, and it was very difficult to get it to sync also. Now it wont sync and I've tried reinstalling itunes agian which didn't help. So I'm looking for some help.

    Okay ... there have been problems reported with that particular combination of the P55/PM55 chipsets, Windows 7 and syncing.
    If your chipset drivers and BIOS are both up to date and you're still getting this, you might have some success using the workaround from the following post. (Unfortunately, not all BIOSes are configurable in this way.)

  • Sound and Vibration Measurement Suite with PC Sound card?

    Hi all,
    I'm new to LabVIEW, so please bear with me.
    I would like to take some basic network measurements of a single channel hardware audio device. I have a PCI sound card which I was able to play sound files and receive input with using the sound2 Simultaneous_Sound_IO.vi. I'm wondering if it's possible and how difficult it would be to integrate this VI with the VIs associated with the Sound and Vibration Measurement Suite? I've downloaded the trial version of the Measurement Suite and it appears to include all of the measurements I need (frequency response, THD, dynamic range), however they're all designed to work with NI DAQ hardware.
    If it is possible, could someone point me in the right direction as far as integrating the two, or even post or direct me towards existing VIs if there are any?
    Thanks so much

    Which S&V vi's do you mean to be dedicated to NI hardware?
    A quick peek into the addon show me waveforms as input and the sound vis have a waveform output.
    OK I didn't look at the examples and by habbit ignore the express vis .   But maybe you just want to use a program instead of programming your application?

  • Problem with date and time syncing itouch to macbook

    i have a problem with the date and time on ical when i sync my itouch4 w my macbookair. whatever i entered into my calendar in itouch will appear different in my ical( with a 6 hrs advance difference) and the alarm i set on my itouch in the calendar doesnt ring at the right time as set even though it is shown the time that i wanted.
    Both my macbook n itouch are set to the same time zone and i have checked this many many times n the time is the same on both machine. but i just dont understand why is there a time difference when synced and my alarm just dont sound at the time it was supposedly set. it rings hours later n showing a different time that it was set but in the parenthesis the right time that i had set it.
    One time my computer ran out of battery n went into sleep mode and when i open it again, the time n date setting was all off. which im surprised why it had gone off. So did this create the problem i have now with the date n time sync or something else?
    please help!!!!

    Having the same problem, & am running Parallels (which I haven't used for some time) not boot camp. I tick the box labeled "Set time automatically" & lock the "click the lock to make changes". When I reboot, the Lock is unlocked and the "set time...." is unticked. Any ideas. Cheers.

  • How do I sync my new ipad mini with my old ipad 2, without losing any apps or data in notes?  I need step by step instructions for first-time sync with ipad mini.  Thanks.

    How do I sync my new ipad mini with my old ipad 2, without losing any apps or data in notes?  I need step by step instructions for first-time sync with ipad mini.  Thanks.

    If you synced it many times, you have to have a backup. It's just a question of how old that backup is now. When did you last sync?
    First of all launch iTunes on your computer and go to Edit>Preferences>Devices. Do you see any backups for you iPad in that window? If so, how new is the newest backup? That will be the backup that you will want to use. But remember that if you use that backup and it is one month old, you can only restore from that date back in time. Anything that you did on the iPad in the past month will not be in that backup.
    Turn on the new iPad Minin and start activating OTA via WiFi. You will get to a certain point in the process where you will be given the choice to Set up as new, Restore from iCloud - or Restore from iTunes. You will want to select Restore from iTunes.
    That is the short and sweet version. There are step by step instructions in this article. This applies to the mini as well as the iPad 4 or the iPad 3 for that matter.

  • HT1296 i have an ipad with many application, will the first time sync erase all the data?

    i have an ipad with many application installed on it, will the first time sync with itunes erase all the installed applications on the device?

    The iCloud settings for the computer and other devices are in the iCloud preferences in System Preferences. If you open iTunes with your iPhone connected to the computer, select the iPhone under Devices in iTunes' sidebar, then click on the Info tab in iTunes' main window. Look at the various items you see listed. Be sure to check the Mail component for your GMail account because it is not an iCloud mail account. Your Calendar and Contacts components should state that they are being synced by iCloud.
