Is there any binding for USB devices?

I am looking for a Java library for USB joysticks.
Does anyone know any?

You want an API to communicate with gaming devices; a joystick, regardless of the method of connection, is just a specific subset of that. There are some options. If you are creating a game or a simulation then you might want to look into the LWJGL API set which is a complete package for graphics, sound and gaming devices and it has a nice community; an alternative is JogAmp which delivers basically the same. High level than that there is LibGDX which builds on top of LWJGL but also allows you to deploy to Android, "html 5" and pretty soon iOS.
If all you want is to communicate with gaming devices you may want to look at the JxInput API.

    If you are using the iPhone camera zoom then remember that this is a digital zoom not an optical zoom. The zoomed in area will have fewer pixels and not appear as clear. The more you zoom the worse it gets. It's like cropping a picture after it has been taken.

  • Are there any fee for developing software for USB non NI harware?

    We develop applications in LabView for pieces of hardware witch communicate via USB. Are there any fee for developing software for USB non NI harware?

    If you really mean distributing software that you developed, then you and a lawyer might want to review the LabVIEW software license - especially the section on distribution requirements (in my 6.1 version it's section 12). You should also contact NI directly and ask them. This forum is primarily made up of LabVIEW end-users and any legal advice you get here is worth exactly what it costs, in other words, nothing.

  • I have an iphone and an ipad (which are connected by the same apple id) i broke the phone and sold it but i didnt get to factory reset it because it was broken, is there any way for me to wipe my iphone from my ipad?

    i have an iphone and an ipad (which are connected by the same apple id) i broke the phone and sold it but i didnt get to factory reset it because it was broken, is there any way for me to wipe my iphone from my ipad?

    Try this:
    Open the "Find my iPhone" app on your iPad, fill in your AppleID and password at the start up screen, and you should see a list of all your devices and their current location, if connected to a Wi-Fi or mobile data network. Devices not connected will be shown as "offline". But you can still trap on the icon and hit "erase iPhone" in the right hand window.
    If your iPhone is not listed, you did not activate this feature during the setup of the phone and it can't be erased remotely.
    If the phone is listed, even as offline, tap on "erase" to send the erase command. The next time your device will be connected to any kind of network, the content will be erased.

  • Is there any hope for a Nano 6th gen that went through the washing machine?

    Is there any hope for a Nano 6th Gen that went through the washing machine?  All of the devices contents are showing up in iTunes when connected but the device itself is not working.

    Hello kpratta,
    There is some hope. I have heard of someone putting the ipod in a bag of dry rice and putting the bag in a dark place for a 4-5 days. After that they used this:
    www.apple.com/support/ipod/five_rs/
    This has the best chance. The rice absorbs any liquid in the ipod.
    Hope this helps.

    Hi, I've been playing Smurf's village for a year now and just last week, i tried to get into the app but it keeps rejecting and goes back to the main page.  Is there any reason for this?  I've been updating the app everytime and now it's not letting me in.  Pls advise. Tq

    Reset the device, restart the device, try downloading any other app.
    All of these are basic steps that could have been found by a simple search of the forums as a resolution for the issue.

  • Is there any way for me to get my music off of my iPod?  I had to get a new computer and no longer have my files...but most are cds

    Is there any way for me to get my music off of my iPod? I had to get a new computer and no longer have my files, most of it is cds...

    Your iPod can only be synced with one computer at a time.  If you try to sync it with a new computer/iTunes library, it will replace the contents of the iPod with whatever is in the new library. You should probably disable the autosync functionality first by going to Edit -> Preferences, clicking the Devices tab, and enabling the prevent iPods,iPhones, and iPads from automatically syncing option.
    Before doing anything else,  authorize the new computer with your iTunes Account.  In iTunes, choose Store -> Authorize This Computer and enter in the correct credentials. Either copy a backup file from your old computer to your new one or create a new backup of your iPod in iTunes before letting it sync.
    Then right->click on your iPod Touch from under the Devices section in the left hand pane of iTunes and choose Backup. You might also want to take a look at this article to see what it all included in the backup.
    iOS: How to back up
    Now onto synced content such as music, videos, photos, etc.  For iTunes purchases you can copy them back into iTunes by choosing File -> Transfer Purchases.  For all other nonpurchased iTunes content, see this excellent user tip from another forum member turingtest2 outlining the different methods and software available to help you copy content from your iPod back to your PC and into iTunes.
    Recovering your iTunes library from your iPod or iOS device
    Once the backup has been made and all other synced content such as music, videos, and photos are back in your iTunes library, restore your iPod from that backup you made earlier.  Here is more on backing up and restoring your iPod.
    iTunes: Backing up, updating, and restoring iOS software
    If you do happen to lose any purchased content, you can always redownload it from the iTunes Store again at no cost via iCloud.  See this article for information.

  • I recently gave my old iPhone to my nephew, he switched it to his phone account, but somehow I now have his contacts on my new iPhone 5. When I look at my iCloud account, it lists his contacts. Is there any way for me to get my contacts back?

    I recently gave my old iPhone to my nephew, I did not clear out my old phone before I gave it to him, when he transferred to his account, he had my iCloud info on the phone, and it updated the contacts on my new iPhone 5 to his contacts. Is there any way for me to get my contacts back?

    This is caused by using the same iCloud account on both phones.  When you do this any data you sync with the shared iCloud account such as contacts is merged and will appear on all devices connected to the account.  To fix this you both need to have separate iCloud accounts (you can continue to share the same Apple ID for purchasing from the iTunes and app stores). 
    Decide which iPhone will be keeping the current iCloud account.  On the one that will be changing accounts, if you have any photos in photo stream that are not in your camera roll or backed up somewhere else save these to your camera roll by opening the photo stream album in the thumbnail view, tapping Edit, then tap all the photos you want to save, tap Share and tap Save to Camera Roll. 
    Once this is done, go to Settings>iCloud, scroll to the bottom and tap Delete Account.  (This will only delete the account from this phone, not from iCloud.  The phone that will be keeping the account will not be effected by this.)  When prompted about what to do with the iCloud data, be sure to select Keep On My iPhone.  Next, set up a new iCloud account using a different Apple ID (if you don't have one, tap Get a Free Apple ID at the bottom).  Then turn iCloud data syncing for contacts, etc. back to On, and when prompted about merging with iCloud, choose Merge.  This will upload the data to the new account.
    Finally, to un-merge the data you will then have to go to icloud.com on your computer and sign into each iCloud account separately and manually delete the data you don't want (i.e., deleting your nephew's data from your account, and vice versa).
    As for recovering your lost contacts, if they aren't on icloud.com when you check from your computer, you will have to recover them from a backup source.  You could try restoring to your last backup but this doesn't always work for contacts.  (Chances are you nephew deleted your contacts from his phone, not realizing it would also delete them from yours.)

  • Are there any fixes for iPad 2 with OS 8.1.1.

    Are there any fixes for the iPad 2 IOS 8.1.1?  I've had problems with Safari and other Apps crashing or locking up, and with extremely slow touch response.  These problems have been occurring since the last update.  At times the iPad becomes unusable.  I have been keeping all programs closed and history and web site data cleared.  Thanks for any help you can give.

    Hi, dannilee,
    I have exactly the same problem. The device was my favorite computer until 8.1.1. Now it runs s-l-o-w-l-y, requires endless reboots.
    To improve the performamce, I have tried these:
    1.Go to Setting->General->Accessibility->Reduce Motion. Turn on.
    2.Reset iPad device settings using Setting->General->Reset->Reset All Settings. Its increase iPad performance little better.
    3.Hold the sleep/wake button and home button upto 8 seconds. This will turn off your iPad. Then turn on iPad. Wait few moments. Do the same thing twice to solve this issue.
    Solution 3 worked for me. And, I always recommend you to backup your iPad first before any action to avoid any data loss.
    Hope it is useful for you.

    What a colossally bad idea!  To anyone reading this thread DO NOT DO THIS!!!  Once anyone other than an Apple Authorized Service Provider (and that doesn't automatically mean your carrier, just FYI) opens up the device, then ALL options from Apple are gone, permanently.

  • Is there any limit for DAQ_Start(​)'s count parameter?

    Is there any limit for DAQ_Start()'s count (the fifth) parameter? It seems that the limit is between 16 million and 18 million. I use PCI-MIO-16E-1 and LabWindows/CVI.

    Hello,
    This depends on whether you are performing a single-buffered or double-buffered acquisition.
    In a single-buffered acquisition, the "count" corresponds to the number of samples the DAQ device acquires and is an unsigned 32-bit value. The largest number that this number can represent is (2^32)-1.
    In a double-buffered acquisition, the "count" corresponds to the size (in number of samples) of buffer that fills up in a circular fashion. It must be an even number. The range of this value depends on the DAQ device you are using and can be referenced by the chart located in the NI-DAQ Function Reference Help file. To access this file, go to your desktop and click [Start]>>[Programs]>>[National Instruments]>>[NI-DAQ]>>[Traditional NI-DAQ Function Reference
    Help]. Then, search for "DAQ_Start" without the quotations.
    I hope this helps clear up any confusion. Please let me know if you need any further assistance. Have a great day!

  • My iPod Touch 4G just shut off one day while i was using tap to post. tried everything and nothing is working not even iTunes! Is there any hope for me? my iPod is my LIFE!!!!!!!!!!!!!!!! oh by the way none of this happened until i updated to iOS 6.

    My iPod Touch 4G just shut off one day while i was using tap to post. tried everything and nothing is working not even iTunes! Is there any hope for me? my iPod is my LIFE!!!!!!!!!!!!!!!! oh by the way none of this happened until i updated to iOS 6.

    I have not had any experience in getting any devices repaired so I'm not sure which store to resort to. An official Apple store should more than likely get you what you need, but I'm guessing it's probably more expensive. (if any cost for your situation)
    I hope you get your problem resolved.

  • HT201304 is there any app for i-5 to virtual typing keyboard?

    is there any app for i-5 to virtual typing keyboard?

    The general method of reducing Other is to restore the device.  If you install your backup when requested, you iPhone will be as it was prior to the restore.  If not, it will be factory fresh.
    Note that Other is usually less than 1GB.

    Hi shishirtusi,
    Thank you for your question, I understand that you would like to know if there is a browser available for the Firefox OS platform that asks for the desktop version of a site, instead of the mobile one.
    There was a bug filed for this feature in the earlier devices of Firefox OS, however there is currently no ETA on when they will include this feature in the Firefox OS browser.
    I understand that this news may be frustrating. However, the [Bug 833150 - Support "Request Desktop mode" in browser app in Firefox OS ] and other bugs for specific devices are bugs that I have found that shows it has been requested before.
    There is also a place in Bugzilla to suggest features here [https://bugzilla.mozilla.org/form.fxos.feature] however I cannot estimated time when this will be available.
