Emmanuel Dreyfus 2d9ada743b Introduce timeout on DESfire operations 
There are a few reasons why an NFC operation may timeout, including
the pn533 USB toggle bit bug. In that case it helps to report the
problem to calling process so that it can retry operation, instead
of hanging forever.

For instance, mifare_desfire_format_picc() may make the chip
unresponsive (see commit 91d3ff9cc4),
but if calling process gets ETIMEDOUT, it can select_application,
authenticate and format_picc again, with some success.

Introduction

Build Status Join the chat at https://gitter.im/nfc-tools/libfreefare

The libfreefare project provides a convenient API for MIFARE card manipulations.

It is part of the nfc-tools, you can find more info on them on the nfc-tools wiki.

If you are new to libfreefare or the nfc-tools, you should collect useful information on the project website and the dedicated forums.

Installation

For *NIX systems

You can use released version (see Download section) or development version:

First, ensure all dependencies are installed:

  • libnfc;
  • git;
  • Autotools (autoconf, automake, libtool);
  • OpenSSL development package.
apt-get install autoconf automake git libtool libssl-dev pkg-config

Clone this repository:

git clone https://github.com/nfc-tools/libfreefare.git
cd libfreefare

Before compiling, remember to run:

autoreconf -vis

You can now compile libfreefare the usual autotools way:

./configure --prefix=/usr
make
sudo make install

For Windows Systems

Requirements

  • cmake
  • make
  • mingw{32,64}-gcc

Building

mingw64-cmake -DLIBNFC_INCLUDE_DIRS=/path/to/libnfc-source/include  -DLIBNFC_LIBRARIES=/path/to/libnfc.dll
mingw64-make

Debug

In order to debug using gdb, you should tune the CFLAGS:

CFLAGS="-O0 -ggdb" ./configure --prefix=/usr
make clean all

It is then possible to debug examples using this kind of command from the root of the repository:

./libtool --mode=execute gdb examples/mifare-classic-write-ndef

If you are only interested in viewing transfert traces between the PCD and the PICC, simply use the --enable-debug configure flag:

./configure --enable-debug
make clean all
