How do you communicate with a USB RAW camera

I have a USB camera which I am trying to control using LabView. I have followed the tutorial, Using NI-VISA 3.0 to Control Your USB Device, and the device is now recognized by MAX. The device came with demo software allowing me to control it through the PC, i.e. change exposure controls, white balance controls, tell it to stream video and when to capture a still image. All I really need to do with LabView is load initial settings to the camera, tell it when to begin streaming video, tell it when to take a still image, and tell it when to stop streaming video, but I have no idea how to talk to the camera from here. For example, I am not sure if my device uses Bulk, control, or an interrupt pipe, and I am not sure how I can read and write from my device even if I knew the appropriate pipe or endpoint. I also noticed that the "VISA USB RAW Control" VI has fields such as "request", "request type", "index", etc. I read some notes trying to figure out what these meant, but I couldn't find anything. With all that said can anybody name any tutorial/article(s) I should read that will help point me in the right direction?  Any help will be appreciated.

Hello kd,
Dennis pointed you to the correct link.  You will need the NI-IMAQ for USB Cameras driver to acquire images from a DirectShow USB camera into LabVIEW.  As you can see from the attached table image, you will need the NI Vision Development Module 8.5 for LabVIEW 8.5.  You can determine which version of the NI Vision Development Module that you have installed by opening the NI Measurement and Automation Explorer, expanding the Software section under My System, and looking for an item called "NI Vision."  By single-clicking on the NI Vision item, you will bring up information, including the version number, in the Attributes tab off to the right. 
Best Regards,
T. McCarty

  • How do you communicate with Adobe?

    When Adobe doesn't accept a legitimate serial number when I try to re-install Photoshop Elements how do I get technical support?

    Now that we have your post in the correct forum, I would like to ask a few questions, to determine the best course of action, please:
    Which version of PsE do you have?
    What OS version are you running it on?
    Did you buy PsE directly from Adobe (the Adobe Store), or from a certified reseller, such as directly from Amazon?
    Did you buy the program with physical media, i.e. DVD's, or as a download?
    If you did buy from a certified reseller, did you Register your software with Adobe?
    Have you logged into Adobe.com with your Adobe ID and password, and looked under My Products to verify that you have the correct S/N?
    As Trevor mentions, if you go to Customer Support, you can do Live Chat (click on "I still have a problem" to sort out many issues, such as S/N's, Activations, etc.
    Good luck,

  • How to communicate with HID USB device under windows XP with Labview

              I have designed a EZ-USB FX2 device and I need to communicate with LabVIEW. I mean I just want to send and receive data. I don’t know how to achieve this goal.Someone have advised me to design a HID device,then use VISA Driver Development Wizards to generate driver(inf file).SO I defined it to a hid device .However when I connect my hid device to the computer, it will automatically be recognized as HID compliance device. I can’t to install the inf file driver. I wondered whether all HID devices will be acquiescently installed the drivers contained in the windows rather than use the inf file driver generated by VISA Driver Development Wizards? If so，what should I do next to communicate with HID USB device under windows XP with Labview? HOPE TO GET HELP!

    Hi,
    I am working on a project using PIC18F4550 MCU and USB.
    I would need to send and receive data from the MCU thru USB. I have uninstaled the HID and created a new NI-VISA driver for my MCU. this worked fine, and it did showed up in MAX
    Unfortunately I was not able to receive data from the MCU, Just sending!
    I thought to use HID.DLL but the way I need to use the functions inside the HID DLL is simply too much for me, I am not a PC programmer.
    There is any kind of VI that is able to use HID.DLL to comunicate with external devices conected to PC thru USB?
    Please Help

  • How can I communicate with other applications from my Java application?

    Hello,
    I need help about how can i communicate with other application(say textpad.exe/wordpad.exe/MS word.exe) from my Java program.
    More precisely, I need to know how i can get the current position of the cursor whether it is in any .txt/.doc files, then I may write some text in my java application and click a button and then my program will append the line(string) in that position of the file which is running under another appliction(Notepade.exe/MSword.exe).
    Please provide me some help.

    I may be wrong (and anyone, please correct me if so), but Java may not be the best tool for something such as this. I envision that you'd have to make some OS calls such as calls to the user32.dll, and while this can be done through the JNI, you'd still have to have a C or C++ program doing the dirty work.

  • Can I use the instrument I/O assistant express vi to communicate with a USB connected instrument ?

    Can I use the instrument I/O assistant express vi to communicate with a USB connected instrument ? My PC is running Windows 2000 et Labview7 express.
    where can I get information or examples on the assistant and USB communication ?

    Yes you can - the Instrument I/O Assistant communicates with message-based instruments through VISA. VISA 3.0 supports USB instruments and VISA 3.0 is the version of VISA that installs with the Assistant.

  • How do you verify LR4 has the RAW plug-in 7.2 update?

    How do you verify LR4 has the RAW plug-in 7.2 update?

    Lightroom does not use the ACR Plugin. The best way to think about Lightroom is that it is "ACR" with lots of other functions/modules, Library, Web, Print, Publish etc. all in one Stand Alone Software package.
    It does not require any other Adobe software to be installed on your computer for it to be fully functional.
    It is not a substitute for Photoshop Cs / Elements but more of an alternative to ACR/Bridge that provides many of the functions of Lightroom but through PS CS..
    That said you need to be running Lightroom 4.2 which is the equivalent of ACR 7.2. LR and ACR are updated simultaniously or within a few days of each other.

  • Has anyone experienced problems with Mackeeper? I did not complete downloading this software. Yet, occasionally when on the internet, I will have the MacKeeper multi-colored circle replace my pointer. How do you deal with this?

    Has anyone experienced problems with Mackeeper? I did not complete downloading this software. Yet, occasionally when on the internet, I will have the MacKeeper multi-colored circle replace my pointer. How do you deal with this?

    Welcome to Apple Support Communities
    Don't download MacKeeper. Users complain about this app and it damages OS X. Also, Mac OS X knows how to take care of itself, so you don't need any other cleaning application that may damage OS X. See > https://discussions.apple.com/docs/DOC-3691

  • Hyperlinks in cells, how do you deal with it?

    I've got the hyperlinks palette open (Windows menu / Interactive / Hyperlinks)
    Selecting a cell (or a table), that I would like to be clickable in a PDF, disables the hyperlinks address text field:
    Obviously hyperlinks from cells are not supported.
    How do you deal with it? Do you put empty textboxed on top of each cell that should be clickable?
    Thanks,
    Andreas

    @Andreas – to choose buttons over text based hyperlinks would mean you can define the area that is responsive like you want (the size is the size of the button) and you could design different button states in different ways (color, images, what not…).
    For the scripter in you: Hyperlink objects have no geometric bounds, Button objects have…
    Just an idea:
    Imagine a script that is scanning all cells of a selected table and if there are hyperlinks detected uses position, width and height of that cell to generate a button just on top of the cell (it could be well on a different layer above) using the information the hyperlink provides. Every time the table is changed by the user and the script is fired again, the old buttons are removed and new buttons will be built…
    If there are more hyperlinks than one in a specific cell, the buttons will be built around the area the hyperlinked text will occupy…

    Back up all data.
    Unlock the Network preference pane, if necessary, by clicking the lock icon in the lower left corner and entering your password. Cllck Advanced, open the DNS tab, and change the server addresses to the following:
              8.8.8.8
              8.8.4.4
    That's Google DNS. Click OK, then Apply.
    In Safari, select
              Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
    and confirm. If you’re using another browser, empty the cache. Test. Any difference?
    Notes:
    1. If you lose Internet access after making the above change to your network settings, delete the Google servers in the  Network preference pane, then select the TCP/IP tab and click Renew DHCP Lease. That should restore the original DNS settings; otherwise restore them yourself. Remember that you must click Apply in order for any changes to take effect.
    2. I don't use Google DNS myself, though I have tested it, and I'm not recommending it or any other DNS provider; the server addresses are offered merely for testing purposes. There may be privacy and technical issues involved in using that service, which you should investigate personally before you decide whether to keep the settings. Other public DNS services exist.

  • How do you get photos off a digital camera and videos off a camcorder onto the iPad air?

    How do you get photos off a digital camera and videos off a camcorder onto the iPad air?

    You can use the camera connection kit.
    http://store.apple.com/us/product/MD822ZM/A/lightning-to-sd-card-camera-reader?f node=3a
    If your camera has an SD card
    or the lightening to USB for your videos
    http://store.apple.com/us/product/MD821ZM/A/lightning-to-usb-camera-adapter?fnod e=3a
    (might also work for your camera)
    The photo part is rather self-explanatory. as long as your photos are in the right format and with the right naming convention they should import right over. The video may be a bit more tricky. So you may want to do some more research and make sure your camera records a format the iPad will import and whether or not you need an app such as iMovie

  • How do you Remove a photo from the camera roll album without deleting from other albums

    How do you Remove a photo from the camera roll album without deleting from other albums

    If it was originally on the camera roll try this: take another unimportant photo for test purposes, copy it to any special folder you have created within Photos, connect your iPad to your computer, locate it as any other external device, and most likely that Photos folder will be the only thing that will show up, locate the photo, delete it and then sync your iPad.
    If the test photo is gone from the camera roll but still in another folder within the app then you know that the system works so go ahead with the process. I understand that there are other photo apps which might let you achieve your goal much quicker.
    Hope thi helps.

    What is the BEST way to get my macbook with lion on it, to communicate with my Canon 40D camera? It says the utility disk is a PowerPC app and that is no longer supported. What do I do now? I can't upload photos from my camera.

    Also, I had the same problem happen when I tried to install an older version of Corel Painter. Are Macbook Pro users just NOT supposed to be able to use their laptops for the purposes they are best designed for?
