-===== Using the PN532 Breakout Boards with libnfc =====
+====== Moved! ======
-[[http://www.libnfc.org|libnfc]] is a mature, cross-platform, open-source NFC library that can be easily configured to work with the PN532 Breakout Board.  While Linux is probably the easiest platform to use libnfc with, it can be configured for the Mac and Windows as well, though you may need to dig around on the libnfc Community Forums for some specific details on compiling .dlls for Windows, etc.
+This tutorial has moved to [[http://learn.adafruit.com/adafruit-pn532-rfid-nfc|http://learn.adafruit.com/adafruit-pn532-rfid-nfc]]
-If you want to test the PN532 Breakout Board out with libnfc, this simple tutorial should walk you through the absolute basics of compiling and configuring libnfc, and using some of the canned example SW included in the library.
-===== libnfc In Linux (Ubuntu 10.10 used in this example) =====
-==== Step One: Download libnfc ====
-Download the latest version of [[http://code.google.com/p/libnfc/downloads/list|libnfc from Google Code]] (ex. "libnfc-1.4.1.tar.gz") and extract the contents of the file as follows:
-    $ wget http://libnfc.googlecode.com/files/libnfc-x.x.x.tar.gz
-    $ tar -xvzf libnfc-x.x.x.tar.gz
-    $ cd libnfc-x.x.x
-==== Step Two: Configure libnfc for PN532 and UART ====
-libnfc currently only supports communication over UART, using any inexpensive USB to UART adapter like the FTDI Friend or a TTL FTDI cable.  Before compiling, however, you will need to configure libnfc to include support for UART and the PN532 chipset, which can be done with the following commmand (executing in the folder where the above archive was unzipped):
-    $ ./configure --with-drivers=pn532_uart --enable-serial-autoprobe
-**Note**: If you also wish to include debug output, you can add the '--enable-serial-autoprobe' flag (minus the single quotes) to the configure options
-{{ :tutorials:products:rfidnfc:libnfc_configure_600w.jpg? |}}
-==== Step Three: Build and install libnfc ====
-You can build and install libnfc with the following three commands, also run from the folder where the original archive was unzipped:
-    $ make clean
-    $ make
-    $ make install
-==== Step Four: Check for installed devices ====
-Now that libnfc is (hopefully) built and installed, you can run the 'nfc-list' example to try to detect an attached NFC board.  Make sure the board is connected to the FTDI or USB/UART adapter, and that it is connected to your PC, and run the following commands:
-    $ cd examples
-    $ ./nfc-list
-This should list the devices that were detected
-==== Step Five: Poll for an ISO14443A (Mifare, etc.) Card ====
-Next, you can use the 'nfc-poll' example to wait 30 seconds for an ISO14443A card or tag and display some basic information about this card.  In the examples folder that we changed to above, run the following command:
-    $ ./nfc-poll
-This should give you some basic information on any card that entered the magnetic field within the specified delay.

-====== libnfc With Mac OSX Lion ======
-scott-42 was kind of enough to post some tips on getting libnfc working on a Mac using an FTDI adapter.  A couple simple changes to the code were required (as of v1.6.0-rc1), with the details [[http://forums.adafruit.com/viewtopic.php?f=19&t=22085#p115684|here]].
-Keeping in mind the code changes mentionned above, the following steps should get libnfc compiling and working via an FTDI type adapter and UART on Lion (using libnfc 1.6.0_rc1):
-==== Download and build libnfc and configure if for PN532 UART (making the code changes above before running make): ====
-    wget http://libnfc.googlecode.com/files/libnfc-1.6.0-rc1.tar.gz
-    tar -xvzf libnfc-1.6.0-rc1.tar.gz
-    cd libnfc-1.6.0-rc1
-    ./configure --with-drivers=pn532_uart --enable-serial-autoprobe
-    sudo make
-    sudo make install
-==== If everything worked out, switch to the examples folder and see if you can find the PN532 and wait for an appropriate tag: ====
-    cd examples
-    Kevins-Mac-mini:examples kevin$ ./nfc-poll
-    /Users/kevin/libnfc-1.6.0-rc1/examples/.libs/nfc-poll uses libnfc 1.6.0-rc1 (r1326)
-    NFC reader: pn532_uart:/dev/tty.usbserial-FTE5WWPB - PN532 v1.6 (0x07) opened
-    NFC device will poll during 30000 ms (20 pollings of 300 ms for 5 modulations)
-    ISO/IEC 14443A (106 kbps) target:
-        ATQA (SENS_RES): 00  04
-           UID (NFCID1): 3e  b9  6e  66
-           SAK (SEL_RES): 08
-There are some dependencies to get libnfc running, but since it isn't an Adafruit project and we can't really support it directly ourselves, you will probably have better luck looking at the [[http://www.libnfc.org/community/|libnfc forums]] for Mac support.  There are a few active users developping on the Mac.
