How-To

To use the PN71XX with libnfc, one must first install libnfc-nci and then install a patched libnfc version.

libnfc-nci

1. Download the libnfc-nci source code
2. Install build dependencies: $ apt install autotools aclocal automake libtool
3. $ ./bootstrap
4. $ ./configure --enable-alt
5. $ make
6. $ make install. This installs the library to /usr/local/.

libnfc

build_deb.sh performs the following steps automatically:

1. Download libnfc source package: $ apt-get source libnfc
2. Install build dependencies: $ apt build-dep libnfc
3. Apply patches to Debian build system: $ ./patch_deb_rules.sh {path-to-downloaded-libnfc}
4. Change to libnfc-1.7.1/debian directory
5. Building: $ debuild -b -uc -us
6. Install packages using $ dpkg -i

Usage

1. Define connection string in /etc/nfc/libnfc.conf. For example on RaspberryPI: device.connstring = "pn71xx:/dev/i2c-1"
2. Use libnfc as usual
