How can I make a labview application for a usb-device?

I've built an application using the FT8U245AM from FTDI. This is a chip that converts signals into usb signals. Now I want to set parameters using labview. There is a driver provided with the chip, that makes it possible to turn the usb port into a virtual com-port. But how do I continue from here? Do I write my application as if it were a classic serial port device, using VISA, or is it more complicated than this?

We had an RS-232 design that communicated with LabVIEW via the plain old serial commands here that needs to be converted to USB and CAN.
A serial-USB chip was inserted to account for the hip USB transition. As i've been told by the electronics designer, it worked without a flaw (I don't remember the type used however).

  • How can I make a "property node" for a VI?

    Hello!
    If I add a boolean button on the FP then I am able to make a property node for that button in the Block Diagram. But how can I make a property node for a VI? I have several VI:s an that together is one program. What I need to do is to verify what kind of VI some of my VI:s is. I need to verify if it is .exe or .vi-file, and if it is .exe then I want to disable run, abort, run continuously bottons otherwise not. I have hard that this is possible to do programmaticaly but I can´t figure out how. I am aware that I could do that manually in the File->vi properties->customize->windows appearance but theese choises makes it last forever.
    I want to be able to stop and run and everything if it is a .vi file, but if it is .exe-file then all those buttons should be disabled.
    Anyone have an example on this?
    In an other message at this Forum I read "You can use the `Front Panel Window. Allow Runtime PopUp`" property to disable run-time shortcuts menues programmaticaly, but still I dont know how to create this property node.

    You really shouldn't open a new thread. If you don't understand something, ask and we will explain it.
    Like I said in the other thread, you can check if you are running in LV or an EXE by using the Application>>Kind property. To get it, place a property node (from the Application Control palette) on the diagram, click it and find the property.
    To set the properties for the VI, place another property node, right click it and select Select Class>>VI Server>>VI. You should have the properties you want under Front Panel Window.
    To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here and here are a couple you can start with. You can also contact your local NI office and join one of their courses.
    In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf). I believe chapter 17 of the user manual explains about programmatic control of VIs.

  • How can I make a bootable disk for Mountain Lion?

    How can I make a bootable disk for Mountain Lion?

    Make Your Own Mountain/Lion Installer
    1. After downloading Mountain/Lion you must first save the Install Mac OS X Mountain/Lion application. After Mountain/Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Mountain/Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
    2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
    Open Disk Utility in your Utilities folder.
    After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
    3. Locate the saved Mountain/Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
    4. Plug in your freshly prepared USB flash drive. You are going to clone the content of the InstallESD.dmg disc image to the flash drive as follows:
    Double-click on the InstallESD.dmg file to mount it on your Desktop.
    Open Disk Utility.
    Select the USB flash drive from the left side list.
    Click on the Restore tab in the DU main window.
    Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
    Drag the mounted disc icon from the Desktop into the Source entry field.
    Double-check you got it right, then click on the Restore button.
    When the clone is completed you have a fully bootable installer that you can use without having to re-download Mountain/Lion.
    Note: The term Mountain/Lion used above means Lion or Mountain Lion.

  • How can I make a intro page for my website, then after the intro has run make the page automatically change to my we site home screen

    how can I make a intro page for my website, then after the intro has run make the page automatically change to my website's home screen

    You can do this using a meta refresh but the problem is you have to add it to the html file for the page very time you publish changes.
    A better way is to create a splash page and upload it to the server outside of the folder produced by iWeb. Example HERE.
    The meta refresh is added to the head section of the html file...
    <meta http-equiv="refresh" content="32;url=http://www.domain.about.com/Page-Name.html">
    The delay time in seconds is marked in blue and the URL to the redirect page is in red.

    You will only know about the hard drive when you try to access it in TDM from your other computer. If you cannot boot into TDM mode or if the drive does not appear on the new computer's Desktop then it is likely bad.
    What you are thinking about as a recovery disk is the Recovery HD normally created when you install Lion or later on the computer. You boot from it as follows:
    Boot Using Command+R keys:
      1. Restart the computer.
      2. Immediately after the chime press and hold down the
          "COMMAND" and the "R" keys together.
      3. Release the keys when the Utilities Menu appears.

    How can I make more email maps for the iPad2?

    If you are on iOS 5 as your tagline suggests and it's an IMAP type account then you should get an Edit button at the top of the list of folders that you currently have on your email account. If it's a POP type account then you won't get the Edit button.

  • When can i make a single edition for an android device?

    From Amsterdam, Europe
    As an Adobe-cloud member......
    1:
    when can I make a single edition for an android device?
    2:
    why can I NOT make a single edition for Android ...
    Whe are not able to use the single edition at all in Europe...(why actually??)
    No one knows when it will be possible....
    And then also what about Android, I do not want to use Apple's hardware, but actually I am forced to do so....I think that that is a big minor for Adobe...
    regards, Anne

    The original problem with android was the file size of the app, i think it was limited to 25/50Mb so have a multi-issue app solved that as the full content was downloaded from adobe servers.
    That may still be the issue, though I thought the file size had been increased.
    You dont have to use a Mac to create you folio's etc, you just need a mac to upload the binary, not Adobe's fault :-) and everyone is in that boat, so not a big minor for adobe then, just you maybe
    have a good weekend

  • How can I change the default application for a content type?

    Running a version of Linux, the default application for PDF files is "Use Document Viewer (default)", which appears to be /usr/bin/evince. I'd much prefer to use /usr/bin/okular; how can I change the default. This question is NOT about how to change the function that is automatically applied when I access a link, in this case "Preview in Firefox", but rather to the default application that I can select when I download a file being viewed in Firefox's previewer.

    This is real progress, a solution to the problem as posted. The command:
    xdg-mime default okularApplication_pdf.desktop application/pdf
    makes okular the default.
    However when I added okular to the choices for applications in:
    * Edit>Preferences>Applications>PDF
    the popup box that appears when I click Download on the preview page changed. The pulldown menu that appears next to "Open with" used to have 3 entries:
    # Document Viewer (default)
    # Acroread
    # Other
    Now it has only 2:
    # Okular (Default)
    # Other
    I'd like it to read
    # Okular (Default)
    # Acroread
    # Other
    How can I control the entries in this pulldown list?
    Also, how can I make the default choice in the popup box be
    * Open With <whatever> , rather than
    * Save File ?
