Does anyone know if there exist a development library for the ACR1222L USB NFC/LCD reader/writer? (I'm not sure if it is compatible with ACR122U or not, which libnfc is somewhat supporting it.)
ACR1222L product page
Appreciate any help.
I am sure you aware that there is an SDK available for the ACR122L (Serial) but not the ACR1222L (USB). These devices appear the same but the SmartCard connection methods/operations are completely different.
The ACR1222L that you are concerned about operates in a fashion that is closer to the ACR122U that it's serial counterpart (ACR122L).
I took a bunch of code that worked on the ACR122U and it also worked on the ACR1222L with little modification.
What platform are you developing on?
A good place to start would be with the ACR122U SDK then buy the ACR1222L.
I have developed for all three devices mentioned above.

I'm trying to use the STM32 Embedded GUI Library with STM32F4 Discovery Board.
Has anyone already done a porting of this library on the discovery?
Otherwise, how can I try to port it and what is the "weight" in terms of work of such a porting? (I'm new in programming embedded devices)
I used Littlev Grapics Library (free, open source) on STM32 discovery. Maybe you will like it too.
http://www.gl.littlev.hu/blog/8/embedded-gui-on-stm32-discovery-board-with-littlev-graphics-library
It comes with a working project to download to STM32 Disocvery.
Maybe you want to take a look at µGFX: https://ugfx.io
It comes with a ton of optional features and built-in drivers. Your hardware setup is already supported.
You might also consider STemWin, it is already supported on STM32F4. In either case the biggest porting effort will probably be in supporting your specific display hardware.
This link will help to implement STemWin on STM32F4.. Link to blog..
It can be easily ported if the drivers for LCD and Touch are properly configured.
I often need simple personal apps on my phone and I'd like to make them. I know some programming (C++, Delphi, some Java, MATLAB, Visual Basic). I don't have any idea about where to start, what can I do, how the issue of "app signing" can impact on this.
One app should help to manage links between book pages, basically it has to handle a small database in which I can add books (title, ID) and linked pages (couples of numbers). The database must be obviously persistent.
The other app should let me program a number of time counters. I don't need persistence between app startups.
I tried Qt Creator, but let alone some problems about installation, it looks like it's made for S60 v5. I don't know where to start. I used to make small utilities for my computer in Delphi, which saved me much time; now that I have a small portable PC like the E5, it could be very useful to have, for example, a portable random number generator, or similar simple apps for personal use.
Someone please give me a kick-start!
Update: I've managed to make the timers application in J2ME, it took a week of investigation (1-2 hours a day)
I did software development for Symbian C++ for more then 6 years. I stopped it something like a year ago when Nokia declared that it is going to kill it. Symbian did not became never popular between application developers because it is EXTREMLY complicated to start developing on it. It will take long-long weeks, maybe months to get running something own for the first time. And that time maybe there will be no new Symbian devices sold... you better invest your time in something that has more future.
Qt is good, qt is MUCH easier to start with and the knowledge you gain you can use also for software development for desktop (Windows, OS-X, linux crossplatform) and other embedded (linux) devices. In one word it has some future.
Qt applications run also on 3.2 devices, just you will have to install the Qt runtime on your phone. You also don't have to use the latest SDK but 1.1.2, this has support for older platforms.
If you want to develop only for your own, you can create a "developer certificate" for free that you can use to sign your applications - they will install only on your phones (you have to specify the IMEI of the phone). You can find more info about signing at http://www.symbiansigned.com.
Take a look here: http://www.developer.nokia.com/Community/Wiki/Category:Symbian
There's a lot of information regarding development options available for S60.
I suggest you take a closer look at J2ME, reasons being:
J2ME is a mature & thriving language with a lot of documentation and examples available.
The midlets (apps) you produce can also be installed on S40 devices. S40 is currently the world's most widely used mobile phone platform.

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.
Simply I am asked to write an application for a smart device (smart cell phone), which will get the GPS coordinates from the device itself.
I have no smart device at all. And I am kind of lost among questions like how can I check if the device have a gps by using the code, if it has how can I obtain them in a "standard" way, do I need to be using frameworks like GeoFrameWork?
So, may somebody list the must or most required things I need to have ready?
Geoframeworks GPS.NET is free these days and it's pretty comprehensive so there's no point reinventing the wheel. It's also friendly to beginners which helps. I strongly recommend downloading it and playing with some of the sample apps. It's a bit tricky if you don't have a physical device to play around with but it does have GPS emulation classes that you can use.
All you need is a copy of VS2008 Pro with the Smart Device SDK installed.

iPhone development on Windows
Is it possible to create iPhone apps using a PC? I'm running windows vista and I want to learn objective-c, what better way can you be motivated then the potential to create something that someone, somewhere might use.
Are there any hacks that allow would allow me to make the apps?
Unfortunately this is not supported. Developing for the iPhone requires Xcode and Apple's gcc tool chain, and it is only supported on Intel Mac OS X (although some have gotten it to work on PPC Mac OS X).
NilObject is right that you can only develop for the iPhone officially on a recent (last few years) Mac with OS X.
That said, Objective-C isn't tied to the iPhone. You can write programs for your PC in Objective-C, which would give you experience without needing the iPhone and Mac. Objective-C is a standard part of the GNU Compiler Collection (GCC). It's rather easy to install with Cygwin.
If you really want to make iPhone applications, you should consider a Mac. You'll get all sorts of experience and can also program for OS X then. Since laptops were just released, many people are selling their previous models because they have upgraded. If you can find an old Intel chip based Mac Mini, it won't cost you much at all (a few hundred), but it won't be fast. The recent Minis haven't been updated in a very long time and are not a very good value anymore for their new price (in my opinion), but they may be available cheap too.
actually, there's an unofficial toolchain that works in windows and linux. you'll need cygwin installed on your pc to be able to work with it in windows.
here's a link to the basic setup: link
though this will not allow you to publish to the AppStore, it's just a good way to mess around with the SDK. Also, whenever Apple updates the iPhone firmware, you'll need to find/wait for the updated toolchain or do some hacking of your own to get the updates headers, etc...
Don't bother. I had a hackintosh and while it worked, Apple can (and does) regularly update the SDK's minimum platform requirement, which means your hackintosh won't be able to keep pace with the new cool features in the SDK, since Kalyway and whoever else need time to reverse engineer kexts or whatever to figure out the new OS.
If you're serious about iPhone, get a Mac. You could probably find a first gen Mac mini (intel) for a couple hundred bucks. Or spring for a macbook and be psyched. The new ones are awfully nice.

Although I thoroughly agree with the consensus: get a Mac, I just wanted to add a little based on this comment you left:
If you are planning to enter the iPhone arena to do one of those Cinderella ten-million downloads at a buck a pop stories you hear about, you'll need a killer app, something new and exciting. Good luck with that; I'm not gonna share my ideas with you, 'cause I'm trying to do the same. :)
That said, I'm in the same boat as you -- I don't have the extra green to buy a Mac -- so I will share some general advice that might help.
Rather than enter the iPhone arena, I've been looking into leveraging my Java skills on the Android phone first. Once I make a few bucks doing that, I'll buy a Mac and learn Objective-C and port my program(s) over. Since Android uses Java and is free/open source, I'm only out the twenty-five bucks to create a publisher account; I can do the rest with Eclipse on any platform I have.
I don't know if it will help you much, but it might be a more cost-effective way to write your Cinderella story. :)
