Does anyone know how to integrate the Playstation Eye with Labview? Can a driver somehow be used to allow Labview to recognize it as a webcam?
You should be able to do this with vision (install IMAQdx and Vision Dev Module)- it seems to be DirectShow, which IMAQ can do- or try out the code found on this page: http://www.labviewforum.de/thread-21279.html - it uses the original dlls.
as there are NO official dll´s for the PS3 Eye on Windows, the ONLY Option is to use the 3rd Party drivers from Code Laboratries or directly interface the Hardware via USB-RAW commands. Code Laboratries PS3 Implementation however does not seem to be 100% conform with the Direct Show standard. You can get a PS3 Eye to work with Labview (via Direct Show and IMAQ), but you will be limited by the usable framerates.
I tried to interface the dll from code laboratries directly, but got stuck on a stange error with the second function i tried (see the already referenced Thread http://www.labviewforum.de/thread-21279.html). However it seems as for now there is a Vi Package available for the PS3 Eye to support LabView under OSX with the full available framerate. More Information can be found here:

Hope this helps.

I was wondering how i would be able to get started with controlling my nikon DSLR camera? I have been reading on the Nikon SDK and MPT/PTP and is really confused on how to start with writing a script to control it. Thanks for helping me.
If you are just wanting to script stuff, under Linux libgphoto2 and gphoto2 are a good start.
You can use them under windows, I'm not sure if there are pre-compiled build available, but that would also require installing the USB wrapper libraries, and that a touch fiddly.
The next step above that is to compile libgphoto2 in cygwin (there are some good guides how to this on the web), but that overkill.
I am currently using digicamcontrol in windows, and for Nikon and C# code it's really nice to use, and very fast, plus it has no hassle on the USB front. It wouldn't be too hard to write a small C# that does what you want (unknown) and then run that from scripts.
this is what you are looking for:

Good luck
In case anybody is still looking at this: the answer is a bit more complex if what you are looking to do is write your own code to access a Nikon DSLR. Thomas Dideriksen's SDK wrapper referenced above is great in making it easy to access Nikon's SDK to control almost all camera functions - but it is restricted to USB-cable access since that SDK does not support wireless access. If the latter is what you want, your best option may be Duka Istvan's digiCamControl, which Simeon suggests above. This open-source C# project can be used as a standalone library. (See the development documentation page.) It is not all that well documented, though, so figuring out how to control all camera parameters can be tricky.
I purchased two Wacom stu-300 signature tabs. I had the ooption of buying the significant SDK/software, but I wanted to interact witht he pads myself. From research I see that I basically need access to wintab32.dll. I cant't find it anywhere? Can someone point me in the right direction?
I am looking to just capture a basic signature. No fancy graphics. Just cap signature. I have tried a few sample apps, but most of them complain about wintab being missing. Wacom seems to explicitly declare that the stu-300 is to be used as part of a compelte solution, and they don;t provide any driver or software for it. The signature pad is installed tho, and shows in devices. Does this tab work / fall into the caterogy of a "tablet" pc functionality?
I would really appreciate some help, maybe a sample app? I would prefer vb.net.
Thanks
It was last maintained by Wacom. The DLL is hidden inside their driver installs. I found it as part of the PenTablet driver version 5.2.5-5a, available at http://www.wacom.com/en/customercare/Drivers.aspx?model=Bamboo&os=
Rather than installing the entire driver, you can extract wintab32.dll from the self-extracting installer.
The stu-300 does not have wintab, Wacom has a set of SDK for the stu tablets, you can request it from https://ssl.wacom.eu/signature.wacom.eu/index.php?page_id=18

Hello everyone,
I recently bought a Sony Ericsson mobile phone and I would like to add a missing feature myself. In fact I cannot actually disable Internet connection in an easy way when roaming, which cost me a lot of money last time I moved away ... So I would like to develop a little application that would just replace the actual Internet configuration with a fake configuration to avoid auto-connections.
So what I would like to know is how can I access programmatically to my phone settings? I know that Sony Ericsson provides a SDK to run Java applications on its customised JVM. So what I am actually looking for is to know if they extended the J2ME functionality to fit their devices requirements.
This is not well documented so I am asking this question with the hope that someone here already had experience with development targeted for Sony Ericsson devices.
Thanks.
NB: This is a Sony Ericsson Elm which is based on the Sony Ericsson OS with SE Java Platform 8.5.
Edit: I accepted QuickRecipesOnSymbianOS answer as it gave me a clue on the only feature that could have helped me, but which is unfornatunately missing. The Sony Ericsson Java Platform is the only API I could use to develop real programs on my phone. But the JP-8.5 does not implement the JSR-307 package which could help me in managing APN. Thanks everyone for your help.
Well, I hope you got the great Vivaz phone, not the Satio.
In order to learn about Symbian OS C++, first go to the Foundation website.
Relevant plug: the latest introduction to Symbian OS C++ in book form is Quick Recipes on Symbian OS
For now, you won't find a better way than Symbian OS C++ to manipulate your handset access points.
JavaME simply doesn't have the correct APIs for this, at least not until JSR-307 is implemented.
I believe Qt isn't integrated quite tightly enough just yet either but that should change soon enough. Keep an eye on it.
Extending the Symbian Python runtime to do what you want would require some Symbian OS C++ anyway.
Yes you will need to use Symbian C++ to modify the CommDB, which holds the list of connections. It is quite painful to work with it directly, but there are some utility classes that can help you out. Take a look at CApSelect, CApDataHandler and CApAccessPointItem, all in the developer library.
And yes, these will work on all modern Symbian handsets, independent of brand.
Note: My answer below assumed it was about a symbian device. Since it was actually a J2me device none of the below applies
The easiest way to achieve what you want to do is probably to just remove all the "destinations" when you want to prevent auto connections. Otherwise the device will test each destination in turn until it finds one that works.
You can also set up your destinations so that they are not allowed to be used automatically. This setting must be done individually for each destination.
You can also group your destinations and set one of the groups to the default. If you set the default to an empty group you should not get any automatic connections.
Note that I have not tested any of these methods myself. When I roam I turn off automatic updates in the apps that use them. Some apps can even detect when you are roaming and avoid auto connects.
There are S60 apps available that improves the connection management of vanilla S60, but I do not know if any of them can help you with your problem.
If you are dead set on doing the programming yourself you have to use the C++ SDK for Symbian S60 available from Forum Nokia. Java ME does not allow you to manipulate the destinations of the device.
The Elm device should have (I haven't verified this) the access point API originally designed by Nokia. Not sure whether you can use it for the purpose you want though. The J2me developer guidelines available from developer.sonyericsson.com should have all the information you need.
I have a Symbian 9.1 handset, Nokia E65, based on Nokia S60 series UI. I'd like to build a simple, full screen, graphic application. It should be able to display some text and pictures and have a basic interaction from the keyboard. That's for me only, not to be deployed.
Now, what do you think is the quickest and most painless way to have it done?
I have the following skills:
- HTML, PHP, ASP.net, JS
- ASP.net and C#, Silverlight
- Java, but mostly for networking, not UI
- Some C++
I have downloaded the Nokia IDE, but it is scary at first sight :)
Any tutorial or example are welcome!
Edit:
In particular, two questions:
is there a possibility to make a stand-alone flash application for that handset?
how about the QT mobile version?
For your device, definitely use Python for S60. It is much easier to start with than Symbian's C++ SDK and in case you ever need more low level functionality than python gives you, you can write small modules in c++ and use them in your Python program.
For a simple application like the one you are describing, Python will do just fine. You don't even need any of Nokia's IDEs / tools on the PC, you can just write the code in any text editor, copy it to the phone and test it live.
As others have mentioned, other options include:
Symbian C++ SDK : As you have discovered the tools and not the most intuitive to work with, development is not straight forward either.
Nokia's WRT : Using javascript/css/html, but it is not available for your phone.
Qt : Not available for your phone.
Java Me : Probably your second best option, your code will be slightly larger but more protable. The tools are not as straight forward as with Python, but definitely not as complicated as with Symbian.
If you think you may like to do some further development on the Symbian platform in future, I'd strongly suggest looking at Qt. Unfortunately, however, you can't use it on your E65, since Qt requires S60 3.1 or higher. (The E65 runs S60 3.0).
Since Qt coding in done in C++, you also have access to native platform APIs if required. For most apps however, the (considerably more user-friendly) Qt APIs provide all the functionality you need.
Depending on your background, the learning curve may be steeper than using Java or Python, but the pay-off is that you get access to a very powerful toolkit. And of course, as long as you use only Qt APIs, your app should be easily portable to other Qt platforms if necessary.
Go for Java ME.
All the things you list in your post is possible to do in Java.
The Symbian SDK for C++ can be downloaded here.
NSBasic is another option.
Kindness,
Dan
May I suggest Python? For newer Symbian handsets I'd recommend Web Runtime (WRT), but it is not supported on good old E65.
I'm obviously biased but I would suggest getting the 2D graphics example code from the "Quick Recipes On Symbian OS" book:
If you know HTML and JS already, you should be able to write a Web widget for your Symbian device pretty easily, using the tools available through Forum Nokia. More info here:
http://www.forum.nokia.com/Technology_Topics/Web_Technologies/Web_Runtime/
These widgets are standalone full screen applications that use the device WebKit browser engine for rendering and UI. You can also use keyboard inputs and customize the softkeys if you wish.
Can anybody tell me where I can find information related to How to Bringup any arm board? I am looking for an overview as I am novice in ARM related stuffs. Any link/document will do ...It will be gr8 help if i can look for a case-study
any arm based board can be considered..I am looking for just a case study...simple in few steps??
Every single ARM "board" will be different. Read the datasheet for the ARM chip you have, that should have a section near the start about booting. Also, read the datasheet about your board, as it made have flash/boot loaders on there. If there are no loaders on the board, you'll have to either set the jumpers for the ARM (if that type supoprts it) to read from external rom, or JTAG the initial boot code into it.
Basically: Read the datasheets. Programming a device like an ARM isn't your usual compile/run stratergy like most software, especially not in the first stage.
edit:
If you don't even have a board yet, try going for this one:
http://beagleboard.org/
It has and ARM on it (as well as a decent GPU).
Check the DLP-2232PB-G evaluation kit from FTDI. Looks great for newbies trying to get into microcontrollers, and it comes with everything you need. It's a PIC controller - not an ARM controller, but the easiest starting point that I've seen... and same basic methods of development.
I would start with any documentation the IC manufacturer may have on "getting started".
http://free-electrons.com/doc/porting-kernel.odp
This link gives a good overview of the bringup of the board with a CPU for which the linux support package is available.
Linux sources in arch/arm have mach-* which are cpus supported by Linux Kernel.
With in the mach-* dir, there are some board specific files that are board specific BSPs.
You can take the process elucidated in this article and try using in your case.
Check out the ok6410-h at http://www.arm9board.net/sel/prddetail.aspx?id=348&pid=200
Quit a nice kicking-start kit coming with everyting you would ever need: documentations, source code, example programs.
recommendable for both newbies and experienced.
