On the output of the application

Hello
Is it possible for a single on demand, but with a sampleclock at 1000 Hz output data point? If the loop itterates every 1 MS material is still programmed? I work with a USB-6211...

Kind regards
Thijs

Well I think you can see that the code you sent is not quite what you asked for in your first post.  One caveat with the code you posted, is that there is a FIFO on the 6211 8 k which will fill quickly upward, leaving you with a fairly large amount of latency (in 512 Hz, 16 seconds of latency).

The feature you have to do what you call in your first post is called 'hardware Timed Single Point '.  Unfortunately it is not available on the 6211.  In general, USB is not a great choice if you are interested in single point of low latency applications.

Based on the example you posted, you would be better to do something like this:

There is no clock sampling in this case, so if you need an exact chronology between the updates then this would not be a good solution.  However, if the OD is just updated with a new DC value based on a slider UI then I don't see why there should be a sample clock.

Best regards

  • Cannot change the output of the application

    I use a small set-up at home to record electric guitar. I got my release of guitar through an audio interface and in my computer via a USB cable, the guitar output then goes through a low latency driver and effects software called "amplitube 3.

     
    I would like to follow the sound coming from the software, however, the application does not appear in my sound mixer. Instead, the output of it goes back into the audio interface (it is recognized as a playback device) for the follow-up of its headphone output. There is a problem such as the headphone output of the interface also monitors the sound of the guitar until it reaches my computer and so the two sounds play together leaving a chorus - like junk. the sound of the guitar before it reaches the computer cannot be resolved by the volume which also adjusts the other output.
    It is also worth noting as the input audio and output to "amplitube 3" can be changed in the program itself however, when the interface is selected as the input, the output is defined as both interface and cannot be changed as long as the interface is at the entrance.
    It may sound complicated so simply, I would like to be able to edit the output of amplitube 3.

  • Where to see the output of my Application Engine program?

    People,

    Hello. I create my first program AE in the application designer and the test in 2-tier mode. I opened the AE in the application of program designer and click on Edit-> delivery of the program. Then, open the log file to see its performance and know that the EI program runs out. But I do not know where to see the output of the EI program.

    The EI program runs only a 'select' SQL statement. ResultSet of SQL's output.

    People know where to see the output of the EI program?

    Thanks in advance.

    Simply executing a SQL in AE produces no output. AE is not designed to be a reporting tool, so it requires a lot of effort to produce this type of output. You can use a "journal" step to write messages to the log file, or a call the MessageBox function in one-step PeopleCode will do the same. However, to write a SQL select results to a file, you use, for example, basic file API methods (& F = GetFile (...); F.Writeline("Hello"); & F.Close (); etc.), methods of layout of the file from the API file & F.SetFileLayout (...); (& F.WriteRecord (...)); or use the query API RunToFile method.

  • General protection fault with tabs and toolbars to the output of the application

    Hello

    It seems that if you have a tab control

    .. .and that tab has a tab with a child Panel control

    .. .and this child Panel has a sign callback function

    .. .and this same child Panel also has a toolbar

    .. .and you do not throw the toolbar when the application closes

    .. .and you do not throw the child Panel when the application closes

    .. .and you do not throw the Panel with the tab control when the application closes

    .. .the application will crash with a general protection fault after the return of the main function.

    Certainly, I consider really cela a bug so as much as there were several things wrong with the code I was working with in order to hit it (and once I set the application everything is fine), but it still took me a little time to track down, so I hope this post can someone put some time in the future.

    I have attached a small sample application that illustrates this problem on my PC in the case where an engineer OR wants to take a peek.  I'm under CVI 2012 SP1 on Windows 7 64 bit.  Thank you.

    I see that I was a little involuted in my previous answer. At Telegraph and hopefully more clear:

    • As indicated in aid, after the chaining of the callback function to the Panel, Panel callbackData should not be modified
    • (solution 1) If you just install a reminder rather than chaining one new this problem is not present
    • I suspect that the instrument of the toolbar handles callbackData parameter Panel. If this is true, you can:
    • Install the toolbar to a panel that does not have a chained reminder (solution 1), or
    • Install the toolbar BEFORE chaining (solution 2) recall: as you can see in the code for ChainPanelCallback, the instrument takes care of callbackData existing and manage correctly in all situations, including the Panel throwing
  • How is it when I click on the menu of the Applications in the Options screen, Firefox crashes?

    Whenever I open the tab Options in Firefox, I can access all items with the exception of the Applications menu. When I click on the Applications menu, Firefox freezes and the only way to fix is to open the Task Manager window and force a shutdown of Firefox. I use the latest version of Firefox and the updates of Windows 10.

    It is normal to have a slight delay, while Firefox generates the list. If you wait more than 10 seconds, there may be a problem with the settings file that Firefox is reading.

    As it is difficult to change, when there is a problem, we offer usually when you rename the file and allows Firefox to rebuild the Windows registry. Here's how:

    Open the settings folder (AKA Firefox profile) current Firefox help

    • button "3-bar" menu > "?" button > troubleshooting information
    • (menu bar) Help > troubleshooting information
    • type or paste everything: in the address bar and press Enter

    In the first table of the page, click on the view file"" button. This should launch a new window that lists the various files and folders in Windows Explorer.

    Leave this window open, switch back to Firefox and output, either:

    • "3-bar" menu button > button "power".
    • (menu bar) File > Exit

    Break while Firefox finishing his cleaning, then rename the mimeTypes.rdf to mimeTypes.old (or another name of your choice, in the case where you decide to roll back this experience).

    Launch Firefox back up again and return to the Options page to specify your preference. The list will load?

  • File in the applications folder

    I accidentally dragged a + 1 GB MP4 file in my applications folder. When I try to drag the output file, it appears only in my movies folder (or another folder, including the desktop) as an alias of 440 KB. Through the get info (command I) I have reset the permissions so anyone can read/write, but the same problem persists. How can I fix this problem so I can drag the real file on applications and in the movie as a complete file folder? It is a weird scenario I have not experienced before.

    Thank you.

    Hey Danielmak,

    Certainly a strange scenario with your MP4 showing a reduction in the size with a few hundred KBs Alias. Not to worry, this should do the trick for you.

    Try right click on the file that is located in the Apps folder, and then click Copy 'filename '. Once you have copied to the clip board, you can then paste the original file in the folder sequences or according to folder that you choose. After you have copied, open the folder that you copied the file and check it's there and can open as expected. If all is good, you can delete the file you have in the Applications folder to remove it from this place.

    Thank you for using communities of Apple Support. Have a great day!

  • the control's behavior bizarre table in the application builder

    I just made the program to change the color of the table control by using the property node (LV 2009 SP2).

    At the code level, it was no problem, but not just any what dye in standalone application.

    It's pretty hard to debug because of the level of the application.

    I attached the file source and built the application to check this trouble in LV2009.

    The front panel for C:\Downloads\exam2\builds\Application.exe\painting_batch_table.vi cannot be loaded, but is required by this property or method.

    The reason was that it does not find the Panel before the calling vi. By linking the reference of the vi parent to your sub vi It should work. See the attached project.

  • Change the default audio device and the recognition of the application

    I'm new to Vista (home premium w/sp2) and I am confused by works the assignment of default device (control_panel-> sounds), specifically the device change with existing applications (running).

    I change frequently between the speakers and the headphones - however, the change of output device is not recognized by running applications, such as iTunes or Firefox and will not be recognized until I have completely quit and restart the application.

    Why?  It is extremely annoying and incoherent other well educated such as Mac OS X platforms.  I would just like to change the default audio output device, on the fly, without the need to restart applications.

    I do something wrong or Vista offers this functionality to the end user?

    Thank you!

    Hello Wyntr,

    Thank you for using the Microsoft answers Forum.

    Currently, the function of switching between audio output devices is carried out manually. To make the selection, you can click the sound icon in the taskbar, then click the button at the bottom of the volume control Mixer. In the properties of the volume, you can click on devices in the upper left corner and select the appropriate device to make it the default for applications open from then on.

    Let us know if this can help, or if you have additional questions on this subject.

  • Error in the application sequence of final launch of closing

    Hey. My debugging code works fine on the device, but on the Simulator (Momentics 2.1.1 and sim 10.3.1.2267) he began to say:

    Launch "Appname" has encountered a problem. Error in the final launch sequence.

    Cannot prepare and download the biinary. Error: The Application closes.

    I think that this isn't a code problem because it works on the device and there is no compiler errors.

    I have read several posts with the same first three sentences as my error message, but none had "Application closes."

    I tried to restart Momentics, restarting my PC, by enabling verbose mode console in Debug Configuration (as someone said).

    I tried a Clean and build together. And I put all the recent code in comment and tried again.

    It is the console output when I build. I'd appreciate any help,

    See you soon,.

    When I press the button in the main.qml the label on the cover of the app (Cover.qml) must be updated. Confirms this label has been updated to debug output. But the steel cover app displayed old value.

    Do I did wrong?

    I guess the reason for this behavior in the strangeness of the Simulator. Thanks for the help.

  • 500 unexpected substitute error when changing the id of the application in - app. XML

    Hi, I'm debugging my app on the real PlayBook,

    I decided to change the application in the - app.xml id, since then, I get an error "500 unexpected substitute" when you try to run the FB4.5 application.

    This threa500 unexpected substitute at the launch of app browsing I understood the problem came from the ID of the application being changed, but not the inner packaging ID used to reference the app in the PlayBook.

    This is verified by looking inside the bar file for application id generated old and new application id, package id remains unchanged. (I think it's actually a bug in the SDK, I'd love to have confirmation of this from someone competent)

    so I thought OK, I'll just delete the app from the PlayBook to clear the former association IDPack applicationid and reinstall...

    but still no hope.

    Here is a detailed description

    old id of the application has been myOldAppID

    new application id is myNewAppID

    generated from the package id: myPackID (even for the two application ID)

    It seems that the PlayBook maintains a list of applications that have already been installed on it: I tried to delete the application from the command line using blackberry - deploy and the package id (obtained from the .bar):

    blackberry-deploy -uninstallApp -device 169.254.0.1 -password *** -package-id myPackID
    

    The app is removed as planned, it is deleted from the PlayBook, the command displays the result menu

    Info: Sending request: Uninstall
    Info: Action: Uninstall
    Info: Uninstalling myPackID...
    Info: Processing 0 bytes
    actual_dname::myOldAppID.debug.myPackID
    actual_id::myPackID
    actual_version::
    result::success
    

    The result, we see that the PlayBook concludes the old reference to my application and displays the ID of the application on line actual_dname

    now, if I run the same command, but with an obviously wrong package ID:

    blackberry-deploy -uninstallApp -device 169.254.0.1 -password *** -package-id someWrongID
    

    I get the result

    Info: Sending request: Uninstall
    Info: Action: Uninstall
    Info: Uninstalling someWrongID...
    Info: Processing 0 bytes
    actual_dname::
    actual_id::someWrongID
    actual_version::
    result::success
    

    Note the line actual_dname is empty, there is no reference for the application with package ID someWrongID

    Here, I'd rather see an output like "application not found for package id someWrongID" but anyway...

    So if I run the same command again, with my application package ID, I expect the line actual_dname will be empty, because the application has already been deleted, but the result is always:

    Info: Sending request: Uninstall
    Info: Action: Uninstall
    Info: Uninstalling myPackID...
    Info: Processing 0 bytes
    actual_dname::myOldAppID.debug.myPackID
    actual_id::myPackID
    actual_version::
    result::success
    

    Here, I see that the PlayBook still holds the former association of myOldAppID with myPackID, even if the application has been removed...

    I tried to restart the PlayBook, cleaning and reconstruction project, all without result... the reference remains in the PlayBook, and myPackID remains unchanged.

    NoI am blocked, if I want my app to debug, it seems that I must leave application ID with the old value...

    I would like to know, is it possible to remove completely an application and all of its references, of the PlayBook?

    And there at - there someone who can explain how the Package Id is generated, and if it's a bug or a feature?

    Thank you!

    Hi Julien,

    This problem is supposed to be fixed on the latest SDK version: 1.1.1. Could you please confirm what command line tools do you use?

    blackberry-airpackager -version
    

    will show you its own version.

    See you soon!

  • The file of the bar - descriptor.xml (and make the application of command line)

    I made a game with air and it is online for sale on Android and iOS. It is somewhat popular and I thought to put up on Blackberry for quite awhile now and with the Port of soon-to-start-A-Thon, this seems to be a great time to finally make it.

    BlackBerry is not very common that here where I live in Sweden, however it still looks like an interesting with a potential platform if I want to get the trip. Unfortunately I don't own a camera myself so I'll use the Simulator. With some graphic problems with the simulator when running in mode BB10DevAlpha (icons does not appear right) and the Simulator is very slow when running in mode BB10DevAlphaSafe (chart appears on the right, but it seems that updating them requires more CPU my computer are available).

    The game is built using nothing other than Adobe Flash Professional CS6 and a bunch of command line tools to build the package and sign. I've only got an old computer with Windows XP now since the death of my main PC, all at the time and since the Port-A-Thon is just a few days I do with what I got.

    Firstly I understand that only AIR 3.1 is supported by Blackberry 10, so I use the old AIR SDK 3.1 to create a SWF (flash) file.

    What I really need to do should be used in the exported SWF file of the game, then use the command line tools provided by RIM to build the package, right?

    Except that I did not count on bar - descriptor.xml to be so difficult to understand.

    I was brought to the documentation here: https://developer.blackberry.com/air/documentation/bb10/bar-descriptor_config_file.html

    It says Adobe AIR at the top, the platform selected is Blackberry 10 and the title says "bar-descriptor configuration file", so it must be in the right place!

    I start by trying the 'bar-descriptor configuration example file"on this page:

    Of course during the test I replaced a few things in the example above with the correct filenames for images etc, I just copied the example of right - off this time to you guys show what I mean.

    Firstly, I extract "blackberry-tablets-sdk - 3.0.0" in a folder on the disc, then I make sure as a full path to the "bin" in the SDK folder inside the path on the OS environment variable.

    Then I read on "Applications of Test using the command line": https://developer.blackberry.com/air/documentation/bb10/testing_your_application_cmd_ms_2010851_11.h...

    Now I run:

    Note that "bg" is a folder with 500 images that must be accessible from the app. I hope that I can just add the folder like this and not type a path to each image file...

    What I get (in lib\adt.jar via the bat file):

    error 101: Namespace is missing
    Error: Validation of the AIR is not

    Okay, so the example did not straight on the box.

    Now, I've read all paragraphs in the first URL I linked above ("the bar-descriptor configuration file"). I start my own XML file and make sure to include everything that is marked as "necessary". That's what I'm left with:

    ===========================================================

    Looks like the XML code that I use when I build for Android.

    First of all it doesn't have the tag root of qnx, but also nothing of the icons are of the required size (86 x 86). The tag required splashscreens and invoke target is also absent, to name a few. No idea of what the entire block of 'extensions' really do.

    Surely, this does not work:

    BlackBerry - airpackager.bat - package installApp - blackberry-myappname - new.bar - launchApp myappname-blackberry-bar - descriptor.xml myappname.swf QNXDevice.ane QNXNetwork.ane QNXSensors.ane QNXSkins.ane myappnameicon36.png myappnameicon48.png myappnameicon72.png bg-device 192.168.8.128

    Success in building the package BAR to my infinite surprise!

    He even managed to install on the Simulator. An icon for the game. However when it auto-couru the app went into landscape, thought for a second and then crashed (or you leave?) without a message.

    Perhaps because the required qnx tag was missing in the XML?
    Perhaps because images in the bg file could not be loaded?
    Perhaps because he had no permission to keep screen from dimming?

    I have no idea. I tried to add XML to qnx at the address previous to the bar - descriptor.xml, I thought that maybe he needed both the qnx block for when you run the application and the application block for when packaging. But now, he has complained of something like XML is not not clean ("' fatal error: markup in the document following the root element must be well-formed." ").

    So he came to it, I have to ask for help if I ever make the deadline of the Port-A-Thon.

    (1) how am I supposed to write the bar - descriptor.xml?
    (2) what command line starting by "blackberry - airpackager.bat" is OK to use?
    (3) all I have to do is build the SWF using Adobe Flash Professional CS6 and then pack it using the Blackberry SDK, right?

    First of all, there are two xml files that you need.

    One is called the manifesto, is to AIR and is called yourappname- app.xml. It is identical to the ones you use for Android and IOS, though some elements will be ignored. It's one you need to switch on the command line, and is probably causing the 'Namespace' missing error message. A file manifest a minimum is:

    
    http://ns.adobe.com/air/application/3.1">
    
        com.example.appname
        My Fabulous Game
        1.0.0
    
        FileNameOfYourSwfWithoutExtension
        YourCompanyName
        
            [This value will be overwritten by Flash Builder in the output app.xml]
            true
            false
            none
            cpu
            false
        
    
    

    Replace the text in red with your own stuff.

    The second xml file is called to the bar of descriptor. It is for App World and the installation process and is called bar - descriptor.xml. It contains information about signing code, icon, permissions etc. A simple bar - descriptor.xml is:

    
    
       
          none
          true
          landscape
          false
          cpu
       
    
       
       your-name-on-certificate
       your-id-on-certificate
    
       core.games

          icon86x86.png
       
       splash-landscape.png
    
       
       2.1.0.1314
    
       
       access_shared
       access_internet
       play_audio
       set_audio_volume
    
    

    Make sure that you at least change the red dots.

  • Unable to return to the application: a UI - EUI: no face is detected

    Being on a specific in my application screen, when I use the application switcher function to switch to another application, I'm not able to go back to my request. The only output generated in the event log when you try to switch back is: a UI - EUI: no face is detected

    Here are the steps to reproduce the problem:

    1. I open my application (everything works fine)
    2. Switch to the application event log, using Application Switcher (assuming that the application event log is already open)
    3. clear the event log
    4. try to switch to my request, using Application Switcher->, after choosing my request, the application switcher function closes but I am still in the application event log
    5. refresh the event log
    6. the following output is generated: a UI - EUI: no face is detected

    The error only occurs on one modal screen, where I use a timer to display a countdown. What is the output "a UI - EUI: no face detected" mean? The cause of the problem would be that I'm using a timer or a modal screen?

    I'd appreciate any help!

    Only, I solved the problem. It had nothing to do with the output "EUI: no face detected '-j' have still not this release quite often for different applications. It seems to be a fairly common output.

    The question was on the screen, there's a single command, which results in a circular call (not obvious) to one of its own callers, which is of course very bad and ended in a ForcedStackTraceException. So it was simply not possible to return to the screen because the computer was tremendously busy (of course) until he was eventually suspended by the operating system.

    Thanks for the help anyway!

  • NavigationPane second push freezes and blocks the application

    I use a navigation pane to view a list of some points. So, if I type an item in the list, it grows perfectly to another page. Burst of this page also works.

    When I try to type another item, the application hangs and crashes.

    This is the output of the console when the application crashes:

    18223290 (EventApp) process ended the SIGSEGV = 1 fltno = 11 ip=786dd9b0(/base/usr/lib/libbbcascades.so.1@+0x22058 code) mapaddr = 000dd9b0. REF = 00000010

    Instead of using the deprecatedPushByQmlString(), I followed how to use objects.

    Someone at - it any ideas what I am doing wrong?

    There is apparently a mistake with this right now, deprecatedPushByString works well. Try that and also you have your "back" button the value of pop or the popAndDelete()?

    Here is the link to the issue, it has been discussed quite well.

    Good luck.

  • Listener for notification/clock without running the application

    We wanted to implement application of traction which runs every hour or so to check the main server for new data and update a local SQLLite database.

    Instead of background application that runs all the time, we were wondering if there a way to plan the such task such as our custom event listener/application launched / will periodically call a Blackberry? When the listener is started, all it has to do is check for data and output backend.

    It is more or less similar to Windows at the special request or cron job.

    Thank you

    You don't have to call it recursively to all.

    Here are the steps:

    1. your application is launched with a specific argument of your choice.

    2. in the main method you are looking for this argument and run your login code.

    3. after the application is completed, schedule it to run again in an hour, or whatever time you want to.

    4 complete the application.

    This process is a recursive process.

    And of course, it's better than running your application when it is not needed.
