Avoid redundant code in PN53x usb and uart drivers. Since it makes sense to
report errors at the nfc_device_t level, pass it directly to
pn53x_transceive().
Programs using the libnfc MAY use pn53x_transceive() to communicate with a NFC
device, and SHALL not use anymore pnd->pdc->transceive(). Code in the library
itself SHOULD avoid calling pnd->pdc->transceive(), so such construct have been
updated accordingly.
New issue
Summary: pn53x_transceive() workaround reverences in examples/nfc-poll.c comments
Status: New
Owner: rconty@il4p.fr
Cc: rtartiere@il4p.fr
The source code of nfc-poll has references to no using pn53x_transceive() for
the status-byte workaround reason in a comment. However this function is not
called in the code. While I guess that's some comment that should have been
removed and have never reached the svn repo, I prefer to be sure that it can be
removed. The comments where introduced at the same time of the file, at r353.
New issue
Summary: Provide a target listing function
Labels: Milestone-1.4.x
Libnfc lacks of target listing function. Actually, applications or libraries based on libnfc have to wrote their own listing function which can provide side effect if two or more of theses libraries are used together in the same application. Plus, some kind of problem could appears during listing multiples targets (i.e. collisions) and this problem should be solved in libnfc (i.e. using NFC chip capabilities), not in applications based on libnfc.
- New API function append_iso14443a_crc();
- Add a PRINT_HEX macro for driver debugging (replaces print_hex function from bitutils.c);
- Move bit-mirroring related functions to libnfc/mirror-subr.[hc];
- Move iso14443 related functions to libnfc/iso14443-subr.c;
- Move libnfc/bitutils.c hex-dumping code to examples/nfc-utils.c;
- Replace calls to swap_endian32() and swap_endian64() functions with calls to bswap32() and bswap64 provided by endian.h.
And while I am here:
- Fix the DBG macro so that it does not throw warning at compile time.
- format '%ld' expects type 'long int', but argument 2 has type 'unsigned int';
- format '%ld' expects type 'long int', but argument 2 has type 'size_t'.
Tested on FreeBSD arm.
- format '%d' expects type 'int', but argument 2 has type 'long unsigned int';
- format '%d' expects type 'int', but argument 2 has type 'size_t';
- unused variable 'nti';
- unused parameter 'argc'.
