- nfc_device is now an opaque type;
- PN53x specific errors are not public anymore;
- nfc_device_name() renamed to nfc_device_get_name() for the sake of consistency;
- examples/*, utils/* uses the new nfc_device_get_name() function instead of access directly to struct's content;
- new error defined: NFC_ERFTRANS for notifying about RF transmission error, its used by mifare.c to detect permissions error on mifare;
- drivers initiator_transceive_bytes() function now returns libnfc's error code on failure (<0), and received bytes count on success (>=0);
- remove some unused errors.
- Add timeout on InJumpForDEP (pn53x) and initiator_select_dep (libnfc API)
- test_dep now works again (except 424Kbps)
- Fix ndi.ndm feeling when select a DEP target
Important: test_dep does not work on PN53x_USB devices after running previous tests
- Provide a nfc_get_default_device() that allow to grab the connstring stored
in LIBNFC_DEFAULT_DEVICE environnement variable or returns the first
available device if not set;
- nfc_connect(NULL) now takes the default device (see
nfc_get_default_device());
- Removes nfc_driver_desc_t from public types
- Defines nfc_connstring as char[1024]
- examples/*: use nfc_connstring
- examples/nfc-poll: now uses only the default device (instead of all devices
availables)
- Removes parse_args() from nfc-utils.[hc]
- Attempt to sort errors depending their source
- Rename DE* errors to differenciate Device-Error and Driver-Error
- Add ENOTIMPL error to raise a error when a feature is not (yet) implemented in libnfc
nfc_disconnect() now switch NFC device into idle before disconnecting;
pn53x_data now have a operating_mode enum to know the current running mode (initiator, target or idle);
new pn53x_PowerDown wrapper for PowerDown (PN532) command;
Note: ARYGON idle mode now to be implemented and ACR122 does not support this mode.
iAbortFd file descriptor array have been removed from nfc_device_t;
nfc_abort_command() can now failed (return false);
nfc_abort_command() now call abort_command pointer from drivers;
pn532_uart and arygon drivers use a pipe-based mecanism (similar from previous one);
pn53x_usb driver use a boolean flag-based mecanism (the previous one does not work as expected);
pn53x_usb now print smarter messages on error at usb connection;
pn53x_usb now handle a strange case: sometimes, the first sent command is not ACKed by PN53x USB device, a dummy command is now sent.
- Move CMake modules from cmake_modules/ to cmake/modules/
- CMake now use cmake/config_windows.h.cmake to create config.h on Windows platform
- contrib/windows.h header is automagically included by config.h
- Put missing NFC_EXPORT macro on front of emulation API
- nfc-mfclassic and nfc-mfcultralight examples are now compiled under Windows
Many thanks to Glenn Ergeerts which provide the initial patch.
- New functions nfc_device_new(), nfc_device_free();
- Add experimental abort mechanism for the PN53x USB driver;
- Move chip-specific variables from nfc_device_t to pn53x_data (Fixes Issue 124).
Suppress any PN53x references in nfc.c
Improve nfc_driver_t struct to embedded HAL API
Merge macros from nfc-messages.h into nfc-internal.h
Remove useless files: nfc-messages.h, buses.h and chips.h
Implement HAL for ARYGON driver
Move send/receive callbacks from nfc_driver_t to internal chip io callbacks (since there are dedicated to pn53x framing)
use a new way to handle drivers
use absolute include path instead of relative ones
move some nfc_device_t members in a better place
nfc_device_t now embeddeds driver data and chip data pointers (useful to be more generic)
use more readable variables instead of strange coding convention
move PRINT_HEX macro into nfc-internal.h
silent warnings with more strict CFLAGS
chips/pn53x: use the powerful C99 writing to construct PN53x commands
chips/pn53x: remove almost all memcpy()
chips/pn53x: WriteRegister, ReadRegister and SetParameters command wrappers are correctly named
chips/pn53x: introduce chip state (SLEEP, NORMAL or EXECUTE)
chips/pn53x: add SAMConfiguration command wrapper (need to be improved)
chips/pn53x: remove almost all const arrays
chips/pn53x: use human readable defines for commands instead of hex values
chips/pn53x: in debug mode, the PN53x command is shown in human-readable string, awesome isn't it? ;-)
drivers: split transceive() into send() and receive() to be able to handle more cases (differed replies, abort commands, etc) later
drivers: use a const structure of functions instead of -dirty- callbacks array
drivers/pn532_uart: major improvement of UART handling
drivers/pn532_uart: check PN53x frames when received
buses/uart: receive() is now based on expected bytes instead of calculated timeouts..
buses/uart: use a smart way to determine available ports on POSIX systems (tested on Linux and FreeBSD)
New Issue
Summary: Remove nfc-message.h file from installed ones
nfc-message.h provide some usefull debugging macros but I am not sure that these macros have to be installed with other files.
New issue
Summary: Improve ISO 14443-B data (ATTRIB_RES) decoding
Before this revision, pn53x_decode_target_data() wrongly decode ISO14443-B. Currently, whole ATTRIB_RES field is stored in nfc_target_info_t struct.
I do not find the correct documentation to fix it better than this, but at least it now retrieves a correct value.
Always use nfc_initiator_transceive_bytes(). If you where using advanced
features and already relying on nfc_initiator_transceive_bytes(), then your
code has to be updated to unset the NDO_EASY_FRAMING option. See an example of
such a change in the libfreefare's repository:

Updates issue 106
Status: Feedback
Romuald: I am not sure about the option enum values. I took 0x02 thinking it
would not hurt but am not really sure about that because I can see many 'holes'
in the sequence.
- Define two sets of DE<FOOBAR> macros: the first one for 'generic' errors
which could be encountered regardless of the NFC device the library is acting
with (0xX000), and ont set for device-dependant errors (0x0X00).
- Make some more functions accept a nfc_device_t* as first argument to have
access to the iLastError;
- Reset errors when entering public API functions;
- Save errors when applicable;
- Distinguish system-level errors (e.g. I/O error) and operational errors (the
PCD returns an unexpected value);
- Minor tweaks.
Update issue 65
Status: Feedback
New review:
Owner: rconty@il4p.fr
Cc: rtartiere@il4p.fr
Summary: Review the error-handling code.
Branch: /branches/libnfc-error-handling
For this development, a strong emphasis has been set on making changes that
will not go through our way on the way to libnfc-1.6+. For this reason, some
constructs are not natural (e.g. error codes defined in two different places),
please keep this in mind when reviewing.
