Why can I write only read during continuous samples?

I am acquisition of analog voltage signals and who to write to a text file when the condition is true, so there is life-long. However, the written files contain only 100 samples (my buffer size)... I need my files to read the samples until the while loop is stopped. How can I do this?

Thank you

Hi Tflax,

The key here is the mechanical action of the button "start gathering. As the mechanical action has been "lock when released" the 'real' value would be read once and then go back to false, then the writing on a measure 'turn on' input file would be true once, that is why it would only write to the file once.

See this knowledge base and the example of 'Mechanical Actions of Booleans.vi' he mentions.

With respect to the producer/consumer, I searched "producer-consumer" to ni.com and came up with a description (first cause), a tutorial and an example of using DAQmx all on the first page of results. Definitely use ni.com research because we have many valuable resources available out there.

  • Why can't Lightroom 5 read these same files to my old 5 d? Any help or fix it please!

    Why can't Lightroom 5 read these same files to my old 5 d? Previous Lightroom could read all my files very well. They were not moved or renamed. "Lightroom has encountered a problem of reading of this photo (!). No idea why or fixed?

    It shows my 5 d MarkIII files perfectly. Still more old files 40 d and nikon. But almost all of my original 5 d files appear in white with the in the upper right corner.

    When I upgraded lightroom the transition of this catalogue and all the remains transferred very well. Just not the old files. I had hoped that an update would fix it but still no luck.

    Perhaps I should remove and reimport?

    Any help is very appreciated.

    One last thing.  If it's on a Mac and that you have recently updated to the 10.9.3, Mavericks then that makes the users folder hidden, so photos down there could be a problem.

  • Why can I connect only an indicator to an indicator?

    When I use under VI with a table or matrix, or just a text string box I can only read if it is an indicator.  If it is a Labview CONTROL said "you have connected an ENTRY Sub VI on a subset table ENTRY".  When I use an indicator, I can't type in the text box when the execution of the VI.  And I can't run if the text box is a control?

    Help, please!

    PS, why is 'LabVIEW' not in the spell checker?

    Open the Subvi when executing?

    Your table must be a control.  When your Subvi is called, you can pre-populate this control with the data that you pass through a terminal connector.

    What does your Subvi when you edit the table inside?  Other calculations?  Just wait?  How to finish the Subvi in order to transmit the data back?

    When you are ready for the Subvi in the end, you can move data from your table control to a table inside the Subvi hint.  The table hint might be hidden or off-screen.  This table hint would be connected to a terminal on the Sub login Panel - VI.  When the Subvi returns execution to the main VI, new data updates that are hidden table indicator now will be present on the wire in the main VI.

  • How can I write or read e-mail messages offline.

    Original title: Windows Mail

    Where can I download Windows Mail. I am running Windows 7 but prefer to have e-mail on my computer software so I can write or read emails in offline mode.

    Thank you

    Windows Mail was used only in Vista. There is a way to hack in, but for the average user, I would say that this is not a good idea. Have a look here for some choice of email client.
     
     

     
  • How can I write only 1 sample every 0.5 second to my excel sheet

    It's the VI I work on... everything works fine but I have too many samples per second on my excel file... I just need 1 sample every 0.5 seconds. How can I solve this problem?

    Thank you very much

    The default values on the DAQ Assistant 100 samples acquired at 1 kHz, then each cycle you get 100 data points.  If you want only 2 points to a second and avoiding the is acceptable, could I plug "1" on the number of samples on the DAQ Assistant (or right-click and select properties to configure the node) and use a software or a timed loop delay in the loop like "wait until the next multiple of ms.  Alternatively, you can use screws more advanced such as 'DAQmx read' to get the desired behavior.  Remember that the data acquisition will be back as soon as he gets the data that you invited to capture, so you'll probably need something to keep periodic things between cycles of the loop unless you want to move to continuous hw timed operation of data acquisition.

  • Why can't PSE 14 read a Canon EOS 5 d Mk iv raw CR2 file?

    I just bought a new Canon EOS 5 d Mk iv and I both CC 2015 and PSE 14. I've updated PS using CC and LR.  LR, PS and bridge now read EOS 5 d Mk iv raw files fine, but PSE 14 has not although he reads very well to pictures of EOS D5 Mk iii.

    in PSE 14 help/subject/Camera Raw = version 9.5.0.585 and

    Help/updates = your applications are up to date

    What should I do to make it work?

    ACR there two versions running simultaneously - a PSE 14 and one for LR and PS?

    I appreciate any help you can provide.

    Thank you

    Jim

    You say that bridge can read your raw files so do you try a right click on the image and choosing PSE14 Editor?  See this picture:

    If this is not suitable for you then try this post:

    It is likely that the various files contain the CODEC, that are either not installed on your computer, or PrE is not able to use them.

    You list several types of files, and I urge you to first see this FAQ entry, then get one of the utilities file info, related to it, G-Spot, MediaInfo, or MediaInspector, then view the details on the different CODECS: http://forums.adobe.com/thread/440037?tstart=0

    In addition, WMP cannot play the video shows the probability of a CODEC problem.

    Or another of the great, try free media players, VLC Player, or MediaPlayer Classic HC. Both contain many useful CODECS, but they do NOT install them in the operating system.

    Good luck, and with the CODEC info, can anyone give your recommendations.

  • I can't choose Canadian dollars during the sampling of a DC plan?

    Right here https://creative.Adobe.com/plans there is no option for Canadian dollars when choosing a plan.  So I'm stuck picking U.S.?  When the dollar fluctuates, I get to pay more or less every month?  It's not fair.  I hope you add Canada option from.

    Lunchababe, right now, we don't have the possibility to pay in Canadian dollars. Thus, you pay in US dollors only.

    If all goes well, in the future we could also add but don't know when.

  • How to check if can device is busy to write or read

    Hi, I'm using NI USB 8472 low speed CAN and I want to check if the device is used.

    because if I send a frame to the device CAN I have a continuous loop, sending another frame and I want to know who I'm not write or read my continuous loop at the same time.

    This loop is made with an asynctimer.

    How can I check if the device is used to prevent writing or reading at the same time?

    Kind regards

    If you choose to use the CVI locking mechanism or the methods of the critical Section of the SDK, the net effect is exactly: a single function that is used by all parts of your program to access a resource atomically. You needn't semaphores here. For example:

    Critical_section cs;         Declare in a scope that includes all threads wanting to use the resource

    void Init (void) {}

    ...

    InitialiseCriticalSection (&cs);)    Do this somewhere soon, before you actually use

    ...

    }

    void CommFunc (...) {/ / This function represents the resource that are not accessible at the same time}

    EnterCriticalSection (&cs);) Stop another thread to run past here

    ... / / Now this block of code can run without fear to be readmitted

    LeaveCriticalSection (&cs);) Finished - let other threads are using the same code

    }

    My main programming in real time, I tend to use the components of the SDK, as described above. Roberto promotes the CVI ones - I think that in this case, their operation is identical.

  • Why even after having changed the permissions can't write to my files?

    I moved files on "users / shared" on the imac 27 "my father Yosemite retina.  He got last June but was not able to migrate because of her old imac was in Florida and North Carolina.  So, I migrated the old imac again with time machine backup charges a few months after getting the computer.  Now, I'm trying to merge the 'old' on the new computer account with the migrated account 'new', I restored it with time machine from the old imac.  I thought I was smart "passage" large libraries of film and photo of users / shared and that the account migrated from old imac. (on the same computer again) But I have no write permissions for files on the migrated account.  And making matters worse, while I can't write to files, I'm still able to corrupt them trying to change permissions and try to load them with i-movie and what not.  So now, I have a 6 GB corrupted movie library and not backup.  I tried it duplication and corrupt also.

    So my question would be "why is it when I add to the new migration full privileges to user for these files, I always failed to write about them?  Now instead, I wonder if there is a way I can fix the corrupted film library file.  Film - I tried and failed on the double.    I tried available i-movie file to 'all' as well as the addition of the new migrated user full privileges to it.  While I was able to do it without error (it seems to take the changes) or the new migrated user or former user on the new computer can write to the file (i-film library) at this stage.

    Every article help I read says just to click on info and change the privileges for what I did.  So I'm pulling my hair out.

    Hope that I was not too confusing in the way that I want to talk about the two different accounts.

    Reset user - file property See post by Linc Davis

    You may need to restore the permissions on your user account. To do this, start on your recovery partition (hold down the command and R during startup) and open Terminal from the Utilities menu. In the Terminal, type: 'resetpassword' (without the), press return, and then select the admin user. You do not have to reset your password. Click the icon of your Mac hard drive at the top. In the list box below, select the user account that has problems. At the bottom of the window, you will see a box labeled restore Home Directory permissions and ACLs. Click the button to reset there. The process takes a few minutes. When you're finished, restart.
