Topic: libnfc for Beginners

Hi

I am new to NFC readers and need some help using libnfc. I have downloaded the libnfc1.1.0 and I work on the Windows platform. I want to write a simple application to autolaunch a web browser for touch a tag. So that, this will be a standalone application, and I dont have to register with touchatag website. Where should I start?

Thank You

At first, you can start with the "list" example : you will be able to detect a card and extract some information like uid.
You also must know that you are using MIFARE ultralight tags if you use touchatag's tags : read some documentation about this tag type.

Re: libnfc for Beginners

Hi rconty

Thank You for the reply.

I started with the list example for the ACR 122 Reader, and was able to extract information. I also went through the code and am becoming familiar with the implementation of the libnfc api.

Re: libnfc for Beginners

Hello,
I am trying to read tags in cycle. As a base I used nfc-anticool example. The problem si, that first cycle is OK, it read Tag for example 0484b5d9a12580. After that I Drop the field for a while and make whole cycle again, but I got different (wrong) tag UID (44005180). What should I do to get the correct tags UID again (without exit the program and run it again)?

Is there any program to handle event when there is a new TAG on reader? (this is may final goal, but I can't solve such a simple task as read tags more time in one program without exit it).

Thanks

Re: libnfc for Beginners

I want to do something very similar, only i am hoping to make the program launch from a mifare classic 4k.  I know there is room on the card, but i don't know if i can make it self launch without having a host program running on the PC, other than of course the card reader and whatnot.  I am super new to this. I haven't even as of yet successfully launched libnfc. I downloaded everything last night at 3 am. it is such an exciting possibilty, and so overwhelming. i don't know where to start.

I am running windows 7 and have an Omnikey 5321 reader installed and running

Re: libnfc for Beginners

Hi!
I am a new developper on libnfc. I'm trying to install the libnfc on windows vista. I have readed the README-Windows.txt file. I've followed all the steps and I got this error :

Re: libnfc for Beginners

hi kchempes,

I see that you are including C:\dev\pcsc-lite-1.7.2\src\PCSC\pcsclite.h .
Is there any reason for this? Normally you should be fine with the one included in MinGW64..
Note that the include directory of minGW should be in your path (see README-Windows.txt).

Re: libnfc for Beginners

Hi kchempes,

Please verify that all necessary directories are added to the PATH environment variable, as described in the readme.
Also i suggest to delete your build directory and rerun cmake, to get rid of cached cmake variables.
If it still fails please post the full output which shows the path var, the cmake output, and the mingw32-make output.

thanks,
Glenn

Re: libnfc for Beginners

Are you sure you set correctly PCSC_LIBRARIES value in cmake ? I don't know how to set it from command line, you can set it for sure using cmake-gui.
You should set it to C:/MinGW64/x86_64-w64-mingw32/lib/libwinscard.a

Hope this helps

Re: libnfc for Beginners

normally setting this manually should not be necessary, the FindPCSC.cmake module should be able to determine this if everything is installed and the path is set up correctly.
The path seems OK on first sight, can you check if the file winscard.h exists in directory C:\MinGW64\x86_64_w64-mingw32\include ?

Re: libnfc for Beginners

Yes the PCSC_LIBRARIES is set correctly. In cmake-gui i don't have errors but it just doesn't work. What libnfc should I use? I'm using libnfc-1.4.2 on windows vista. Now I moved on Windows 7 because I thought it was a problem of vista but i still got the same error.

Re: libnfc for Beginners

Should be found automatically as well if you install it like described in the README file.
It looks in your Program Files directory for a LibUSB-Win32 directory. Note that you should rename the dll file as described.

Re: libnfc for Beginners

Hello,

Turn ON debug mode, that could help to find what is going wrong.

You could also try the development version.
