How can I control external devices using a stand-alone touchscreen with a LabVIEW app

For my senior project my group design and created a vehicle for extended range hybrid with 90 Li + battery which is charged by a 15 kW generator and/or who is also charged by a 5 kW fuel cell. Currently, our system is able to measure the tension on batteries and display them on a laptop via LabVIEW. To process these data, we use a cRIO FPGA. What we would like to do now, is having a touch screen for the pilot to choose which loads of source of battery power so that monitor a pressure reading from the fuel tank.

What kind of touch screens to LabVIEW to be downloaded on and used for controls?

A cRIO has the necessary capacity to supply such a screen and handle the transfer of the data from the sensor fuel and relay (for turning on and off will deepen)?

Do I need an additional license to create stand-alone applications and how I would go about creating a stand-alone application?

Sorry for the question as much. Any help with the answer. Thank you!

This looks like a very interesting project.  If you are interested, National Instruments organizes an contest of Design student where you can win cash or a trip to Austin for NIWeek.

NEITHER sells computers touch screen that can be used to control LabVIEW applications.  You can find more information here: HMIS and industrial touch panels and here: LabVIEW Real-time and Touch Panel Deployment and replication resources. Our computers 6-inch touchscreen , run Windows CE, programming on them is a little different from the programming on a full Windows operating system.  You can find useful getting started with LabVIEW Touch Panel Module .

You can use third-party with the LabVIEW Touch Panel Module devices, although it takes a deployment license for it.  More information can be found in the getting started guide.

If you were able to send the information of cRIO on a network (which according to your description, seems unlikely), you can use a smartphone to control your application.  More information on our community of Smartphone group.

If you use the 6-inch touchscreen panels, they need 18 to 32 VDC (the fuse becomes an open circuit if the input level exceeds 33 VDC).  The transfer of data from the switching relay can be monitored and changed with the touch screen.

If you have traveled the road of the touch panel, you need to purchase the LabVIEW Touch Panel Module and a touchscreen.  Touchscreens OR have a touch panel deployment license.  Guides step by step to create the stand-alone application are in the getting started with LabVIEW Touch Panel Module .

  • How can I remove the persistent database on stand-alone simulators?

    I use stand-alone device simulators (not of JDE or Eclipse according to) to test an application on multiple platforms. In order to do some tests first-time behavior, I need to blowing the persistent data store before each new installation. In the JDE-based simulators, there is a clean.bat which does just that. However, for these simulators autonomous, that I can't find anything like that under the folder, they were installed in. I tried to reset, and I tried to uninstall and reinstall the Simulator itself, and yet the data is * really * persistent - won't go away. Of course it's stored somewhere else.

    Does anyone know how to remove all data on these stand-alone simulators?

    I use Windows Vista, 4.2.1\4.2.1.96...7130-Cingular ...\Research in Motion\BlackBerry device simulators Simulator.

    You can find the files in your Users in AppData directory.

    Click on the C: drive in Explorer, and then look for *.dmp.

  • How can I control 4 sets of compact system of RIO with my host PC?

    Hi all

    As the title.

    I want to control 4 sets of compact system of RIO at the same time.

    I wrote before for two PC TCPIP connection.

    But I never program to connect to multiple PCs.

    If I need to connect several PC, can I configure different PC connection port?

    Could you give me an example?

    I thank very you much.

    Hi StephenCh...,

    You can calculate the transfer rate that depends on your network card. You will find very good examples on it in the finder of the example, search for tcp/ip. You can use the code on each of your cRIOs server. Use the client to connect to your servers (cRIO), you have to change the IP address. If you need to connect to all at the same time, you need to change the client program a little, so that you are able to build four connections.

    Where do you have problems? Have you ever seen the examples?

    How can I make the best use of a new external hard drive and a new catalog full of photos just loaded into Photoshop elements 14 Organizer?

    Keep all the files on external hard drive image?  Nothing else and no pictures on the desktop?

    Keep all image files both places?

    What is the best way to go through thousands of images in the Organizer to identify and place them in files?

    Once I've placed a file, I just leave it in the entire catalog or a way indicate to me that it has been sorted?

    As overwhelming, any tips/shortcuts/schemes, you can offer are welcome!

    As I only have the version of the EP, here is some info on the organiser:

    https://helpx.Adobe.com/Photoshop-elements/how-to/use-elements-Organizer.html

    Independent of how this feature works, you want to have your photos in one place and have a backup (second copy) somewhere else. All hard drives will not be successful at some point - some more early, some late - never trust to have your files in any safety devices if they are on a single disc. Once you have your sorted, it would be useful that you will organize/name/tag new photos immediately if the task is relatively short and simple. I copy my photos on my internal hard drive for my camera, take a quick look with preview to see who needs some changes and then decide where to put them - either drop them immediately after naming them or bring in an editing application and then file them away.

  • When I try to copy a file to an external device using Windows Explorer I get the following error message: "cannot copy. The directory or file cannot be created. »

    original title: could not copy files

    When I try to copy a file to an external device using Windows Explorer I get the following error message: "cannot copy.  The directory or file cannot be created. "I understand that I may have the physical limit of USB keys for the root directory.  How can I fix it?

    Hi GloriaZF,

    What is the size of your external hard drive and what is the available free space? Open my computer-> right click on the external hard drive-> properties. You will not be able to copy more data if the disk is full, or who have less space compared to the size of the file you are trying to copy.

    You need to remove the order data to make the space more. Deleted data from the device USB will be permanently deleted and will not be stored in your Inbox, so take care while eliminating unnecessary data.

    I hope this helps.

  • How can I control a button from a swf file to another swf file?

    Hello

    I have a file main.swf . From this file I can access the file external.swf which is an external file.

    Now, how can I write code on my file main.swf to the button that is on my external.swf file?

    Activities.MainPanel.close_btn.addEventListener (MouseEvent.CLICK, btnClickClose);

    Activities.MainPanel.close_btn (This button is actually the external.swf file, but I want to write code on main.swf file to run it on external.swf) How can I control a single swf in another swf file button?

    Thank you.

    Some examples of code that you should be able to adapt to your needs.

    create a new instance of the loader object.

    var loader: Loader = new Loader();

    make the download request...

    var request: URLRequest = new URLRequest ("external.swf");

    Add a full event for the loader listener

    loader.contentLoaderInfo.addEventListener (Event.COMPLETE, completeHandler);

    start the actual loading process...

    Loader.Load (request);

    Create a new empty movieClip instance, you place the movie loaded into this movieClip after loading

    var externalMovie:MovieClip;

    This function is called when the download is complete and the file is ready for use.

    function completeHandler(event:Event):void {}

    set the contents of the film to the new empty movieClip...

    externalMovie = MovieClip (event.target.content);

    Add this new film to the display list.

    addChild (externalMovie);

    }

    Now you can reference the film loaded with the name of the instance 'externalMovie '. So if, for example, you want to address a button in the film loaded, you can write something like that on the main timeline:

    externalMovie.addEventListener (MouseEvent.CLICK, btnClickClose);

    function btnClickClose(event:MouseEvent):void {}

    }

  • How can I control the working time so that the loop structure in the cases where the structure?

    Hi all

    My job is: Loop While structure generates the signal for 4 seconds when you press the 'start build' button, after that data has been backed up. You press the button "generate the beginning' once again, and the loop runs one again.

    My problem is: the first pressing, the loop, exactly 4 s (3, 999 s), but him second, third pressing on... The time elapsed is not 4 seconds, always smaller (even ~ s 0.003). The loop works correctly after press the "Exit" button and launch the program again.

    How can I control exactly time loop work While Structure without the press "Exit".

    Thank you any help!

    P/S: I used the number of cycles (ms) just to look at a working time of the While loop.

  • When you open a Photoshop file with Bridge, how can I control what version of Photoshop, the file wil

    At the opening of a bridge of fthrough Photoshop file, how can I check which version of Photoshop, the file will open in?

    I store my PSD files that is adjacent to the original RAW file which it originates.

    If I open the folder and double-click this PSD file, it opens to the CS6. But, if I use the bridge (CS6) for access to and open the same file, it starts by is Photoshop CS5 and then opens this file PSD in CS5.

    How can I control which Photoshop will open a file then choose to open it through Bridge?

    Interesting, but it does not give any idea what I'm supposed to do. No Photoshop ducuments listed.

    Look at the PSD file on the location of Curt and Photoshop Document research. Beside him ideally should show Adobe Photoshop CS6 if you have Bridge open CS6. Click to provide the fly on the menu and choose the correct Photoshop from the list.

    But probably something went wrong with your installation. By default, Bridge chooses the latest version of PS to open its plug in.

    Maybe reset preferences may also help you. Can you provide more details about the version of the OS etc.

    And you have a good reason to keep your Raw and finalized in the same place files. Personally I put them aside and use a convention of appropriate filename (YYYYMMDD and details) so I can easily search the DNG files in my archives if I needed, but I don't make mistake by opening a bad
