PWM synchronization problem

Hello

What I want to do:

I need to output a PWM signal with variable frequency cycle and duty using the DAQ assistant for a card with digital output. The max frequency should I * need is about 500 Hz.

What is stop me:

I can't understand how my cursor frequency relates to a real Hz frequency.

What's next:

Well, I wish that a simplified approach to exit a pwm signal to a digital output on a camera card or be able to determine the timeing/frequency/delays more. I guessed just to get a wave that looked nice on the graph, but I have no idea on what is the actual frequency. (How can I measure it, so I can guess and check to understand a range I need?) No change to my code attached, or new ideas would be great! I'm still fairly new to labview for details is less appreciated.

I hope that it makes what I'm doing.

Thank you!

GerdW,

This seems to be much more accurate. I used the ms timer as my input, so I reduced my input par.001 frequency to compensate for the difference of thousands on my clock. This seems much more accurate.

Thank you.

Edit: Yes its cDAQ by the way.

  • iPod connection and synchronization problems classic160GB

    I have a well taken in charge iPod classic 160GB. Worked perfectly until...

    Since the upgrade to the latest OS (iMac), I've been prone to random error when updating of my music. Essentially (1) the device is still connected and there is no apparent way to perform a good ejection process (2) and synchronization fails after many hours and don't care only about 100 songs.

    Thus, it seems that the iPod is ok mechanically. I have reset the device and formatted the HARD drive. This allowed then the synchronization process works correctly. Yesterday I downloaded the songs on the iTunes store and wanted on the iPod - same problems error has occurred.

    Would it not make sense to go back to an earlier version of the operating system? and iTunes? (same iTunes appears unstable now...)

    I see that this timing issue is quite common with this unit holders and it seems to be common, because support was arrested for this camera - I'd be cynical? Why isn't Apple in the face of what it comes to very bad reputation management - total contempt for Affairs of its user base?

    I always use what is apparently a good piece of hardware, but I'm extremely frustrated as a user. Any body found the corrective action? If so, what is it?

    LAST: I left Apple and bought a Sony HD camera. Why? as a result of these frustrations. I'm now evaluate whether to consider other Apple devices that are close to replacement (viz, Ipad, MacBook Pro (17 "), iMAc) with non-Apple devices. This is how frustrated and I'm in a bad mood.

    Please, if you know a solution, I am very willing to try that.

    Problems with synchronization is often caused by a hard drive which becomes unreliable.  Hard drives are mechanical and ends by fail, computers and iPods.  I have much older iPods (4th gen, 3rd generation and iPod mini) that are more than 10 years at this point.  They still work perfectly fine with the latest version of OS X and iTunes.  I replaced the fragile hard drives in three of these iPods with Compact Flash card or an SD card on an adapter.  For the 5th generation and later iPods, you can look here for more information

    https://www.iFlash.xyz/

    I see that this synchronization problem is quite common with this unit-holders...

    It's not just 'common good' considering there are millions of iPods (with storage on hard disk) still serving there.  However, if you see more cases of these days, the reason is obvious.  They age, on average.  The iPod classic model was released back in 2007.  Old things tend to start fault for various reasons, including defective hard drive.

  • ARM module + PWM LM3S8962 problem

    Hello.

    I'm experimenting with LV2009 + Embedded module for ARM (also the 2009 version).

    (1) what actually works, a few screws, I did (no examples):

    -loop infinite + led flashing + 200ms wait timer

    -infinite loop + number of the current iteration on LCD + 200ms wait timer

    (2) the demos provided in /examples/lvemb/ARM/LM3S8962 sistematicaly (PWM, Blinky, DIO, OLED) fail. Ex: DIO relies, but throws an exception when it is downloaded on the dev. BOAD and executed; PWM does not build (not a filled.ctl or a update.ctl lack of file problem, I fixed) - something related to a PID Subvi. What I'm doing wrong here? Any help? (Note: I also changed the parameter debugger & programmer of the project uVision, the default ULINK2 fails of course).

    (3) PWM EIO problem: I got the first aforementioned VI (1) (LED light MagNet) and added a HIO PWM5, in the same loop.

    -What is the wired to the PWM EIO node value mean? Duty cycle 0 to 100? Duty cycle 0 to 1? The number of ticks to the top state PWM? Sometimes it worked, sometimes the PWM was logical high all the time.

    -If I add a property PWM5 EIO node and try to put anything, it breaks. From what I've seen in the uVision debugger, it gets stuck in the default interrupt handler section. I can't understand how he got there.

    Please help me with an example of how fully configure a PWM EIO, exercising control over the frequency of having to test cycle, everything.

    Thanks in advance for your time & help.

    Paul.

    Hi Paul,.

    This looks like a problem where you (or rather the code generated LabVIEW) set up the device before you activate the device PWM.  The target will fault in this case, but the Simulator will not.  Because that the PWM EIO node initializes and allows the PWM peripheral, if the EIO property node is executed before the EIO node, the target reproach.  Try using a sequence structure to make sure that the node of PWM EIO runs before the property node.

  • Does space empty between the video clips a synchronization problem in first?

    In the past, when I wanted a second or two of black space between video clips, I just leave the empty space, which fell to black on each side of the gap.

    Can only cause audio/video sync issues? Can I actually save some black frames and fill these gaps?

    I just loaded a video on Youtube, and it gives me an error message I could have synchronization problems.

    Thank you

    Leonardo

    From my experience, empty spaces will not cause any problem whatsoever.  Done it for more than a decade in every version of Premiere Pro.

  • Pinch and Zoom - synchronization problem

    Hello

    Since v25, iPad Apps have a pinch and Zoom synchronization problem. If hitting swipe to a page, you cannot directly Pinch & zoom, using the two finger gestures. Firstly, it must wait 1 to 2 seconds (whats darn long) until you can zoom. Even if the PDF page is fully loaded (already sharp/readable).

    On some pages that do not have something different than the other pages, you must first zoom out, before zooming in works.

    Very strange problem. Someone at alse noticed the same thing?

    I'm using the latest tools of InDesign CS5.5 v25.

    Kind regards

    Yves

    We have seen problems with pinch and zoom on v25. It is not so much a timing problem that the gesture is very sensitive to how far your fingers are when you start pinching. We turn to her with a fix in v26.

  • IPod synchronization problems

    So never had a problem in the past, but I try to sync the albums selected on my ipod, I sort iTunes plug in select the albums that I want and click on synchronize.

    It is synchronization of the songs for about 1 min then saying its full but when I go on my ipod, some albums are available, others are but fade entirely grey or one or two songs available. The greyed out are only available online.

    Also the cover of the album is not synchronized on albums which they already have.

    Also tried sync any library where before it took all night en to synchronize its saying its done in like 1 min.

    Very very frustrating because I have a slight OCD with it!

    Thanks again

  • Synchronization problems

    I am running windows 10, iTunes on a laptop Dell Inspiron 12.4.3.

    My problem is with one of my devices with iTunes sync.

    The Ipod is running IOS 6.1.6

    When I check manually manage music & checked synch only of songs, it synchronizes only the recently added songs (i.e. only 55 songs added the other day) and does not add that other albums checked.

    The IPhone is running 9.3.4

    When I check manually manage music & checked synch only of songs, it synchronizes only the recently added songs (i.e. only 55 songs added the other day) and does not add that other albums checked.

    I suspect that the problem is that you try to manually manage music and synchronization. You can't do both, you will need to take one or the other. If you want to synchronize, and then set all your sync settings. If you want to manually manage music, then you click and drag the music from the library to the device and don't have any setting to synchronize music.

  • iCloud bookmark synchronization problem...

    My favorite is synchronized between 2 MacBooks and iPhones 2 (of which 1 is used only via wifi)

    Recently bookmarked is not properly synchronized without apparent reason.

    Symptom:

    1 one of form 'bar' favorite items - let's call it "Site X" - changes its position to become the first ⌘ + 1

    2 "site X" can not be deleted or changed in any case.

    3. I tried to remove bookmark.plist in the library folder and then synchronize. The result is that only "Site X" stays on the bookmarks bar.

    4. only after this, you can remove or change "Site X"-, but this dose not sync between devices.

    5 bibliography and other items on the bookmarks folder cannot be added or removed. They do not synchronize either.

    6. all other iCloud products works well. This includes Safari same transfer between devices.

    I don't mind total delete existing bookmarks but want to recover the ability to sync between devices.

    Thanks in advance.

    I have the same problem. I can't organize or remove the bookmark on the MacBook Air 11 (OS X 10.11.3) & 5s (iOS 9.2.1). iPhone On iPhone 4 (iOS 7.1.2) everything works fine. Called support, they said wait should be quickly corrected.

  • LTE application: Signal PSS and EU synchronization problem


    Just as I suspected, samples received on the receiver side are only cross correlated with the PSS sequence (PCI mod 3) = 0, this is the reason why the synchronization does not work when the eNB transmits with a (PCI mod 3) 0. The PSS sequence (PCI mod 3) = 0 is integrated as a time fixed signal of the domain in the FIR filters although (the two who treats I and rated a Q of the received signal handling complex). To change this and to implement a different sequence of PSS, should open the basic FIR blocks Xilinx generator and change the sequence.

    I got some guys from support LabVIEW Communication an updated version of the "LTE Cross Correlation.gcdl" function that implements a selective control for the value (PCI mod 3) and seems to change the PSS sequence within blocks of FIR. I post here if someone has the same problem. Although I have not tried myself yet.

  • Windows Movie Maker audio/video synchronization problems

    I am changing a video on Windows Movie Maker (5.1), and when I cut a piece of the file clip and trimmed other part beside him, some delay seconds started with the change. Only, it starts at one point and continued for the rest of the video. I need to solve this problem, and I'm terrible with computers. Can someone help me sort whatsoever?

    It would be a massive help!

    Something to try...

    For the timeline... trying to drag a second instance

    Right click / Mute the Audio track.

    You can drag the file to the audio / music
    left or right then maybe you can synchronize audio

  • Memory internal & external synchronization problems

    I'm a few problems of synchronization of internal and external memory - it will sync perfectly with the internal memory, but then used to synchronize the rest of the songs to my micro SD card, I have had worked in the past, but do not remember what I actually did, when I have external sync that he's trying to just put all the songs once again. Pointers?

    Do not use automatic synchronization. Choose for yourself what songs to put and where to put them.

  • Windows Mobile Device Center synchronization problem

    I recently developed a problem syncing my phone Windows Mobile 6.1 with Vista 64-bit Home Premium WMDC.  I would appreciate any idea or a reference to help me solve it.  I'll give you only a capsule summary chronological here to keep this short note.

    -There are synchronization three weeks was normal.  No change in system done other that what is described below.
    -Signed with the local provider (Comcast) for Exchange and Sharepoint hosting services.  They ran an installation script that changed by the Outlook 2007 adding the exchange server profile and who knows what else.
    -Phone sync is no longer with the PC; only with their Exchange Server.  They claim that they did nothing to make (their inventory of skills for Windows Mobile does not exist).  WMDC still sees the phone as a guest.
    -Spent the weeks then 2 + talk with Comcast level 3 troubleshooting, manufacturer (HTC) phone and cellular service provider (Sprint).  All to various help desk levels.  I spent a lot of time searching for answers on various blogs and other credible sites for answers.
    -Journal of phone calls said that the error is 0x8503001f which says that my profiles are out of sync.
    -One of these help professionals tells me its something to do with my user.sdf file.  This file is not present on my PC.
    -Sent in notice of cancellation to Comcast, which is still in the queue for processing.
    -Sprint technical support abandoned and sent me a replacement phone.
    -New phone has the same problem.  The problem is clearly with WMDC, file or a registry problem.  Utilities that I find on the internet for the problem works only with 32-bit operating system.
    -J' tried to uninstall and reinstall WMDC and the other fixes I found on TechNet and other Windows Mobile sites.  Nothing works.

    I'm not a developer, but I'm a power user who is used to run organizations, so I'll have intelligent conversations with these people.  They are perplexed and so I am.

  • (FirePower 7010 and FireSight) synchronization problems

  • BlackBerry Smartphones to BB Bold 9780 Outlook Contacts synchronization problem

    A few weeks ago, when I started to sync my Outlook Contacts to my BB, a message window pops up letting me know that RIM is no more using the same method to do.  Since then, I was unable to carry out a synchronization.

    When I start a synchronization, first of all, he said "Have information of the State of the BB address book" and reads all of the records quickly, then he said "Have information state of Outlook Contacts" and reads all of the records quickly. After that, he said 'get more information state of Outlook Contacts", but underneath, what is said"Card reading 1", then"read 2 records", etc as there are records.  She does very slowly, as it takes 20 minutes to read 50 records and I have 1900 records.

    I called T-Mobile, they couldn't help me.

    I uninstalled and reinstalled the desktop software.  I have updated the software of BB. None of these permits.

    Last night, I left my BB plugged to the computer at night to see if she would complement all.  In the morning, the BB Desktop Software had closed and the contacts were not properly synchronized.

    Help!  I need contacts on my phone.

    Hi - I'm the one who reported the problem at first.  I found the CD Moose comes with the phone and installed the old version 6.0 of the BB Desktop software.  My Outlook Contacts now synchronize very well, as they did before.  This seems to have solved the problem.  Maybe the other person with the same problem can do the same thing.  The other thread has a link to older versions of the software, but I hesitated to use because he said it was for Verizon and I have T-Mobile, but if I could not find my old CD, I would have given a trial.  I mention this just in case you do not have the CD.  Many thanks to those who helped and good luck to others with this issue.

  • BlackBerry storm smartphone synchronization problems

    Hello. I'm new to this forum. I just got the storm. I used to have the palm tx. When I open the bberry Desktop Manager and click on the device switch Wizard to synchronize my info from the Palm to the storm Office Manager, opens the window of the migration wizard. When I click Next, the window becomes "select desktop organizer", where I can choose the software to import from. But the options are not underlined, so I can't select the option of palm treo/Organizer. What's wrong?

    I know I have the Palm TX not the Treo, but I just want to download it from the desktop organizer that is the same for both. Both my Palm and the storm are connected to the computer and I have Windows XP Home Edition. My Palm Desktop Organizer is version 4.2, which is not on the list of the bberry Manager compatibility, but it is a later version, that shouldn't be a problem. Should I get a Treo (temporarily), synchronize it with my computer and then try to transfer the files to the storm? Or is the problem something else? Thank you.

    Hi and welcome to the forums!

    I think that your Palm 4.2 is not compatible. The last article is 12/8 and ignores the right 4.2
