- Rename the nfc_device_t's struct iErrorCode member to iPICCError (We are
likely to have both PICC and PCD errors fields to avoid unneeded complexity
at some point);
- Make the PN53x error descriptions static;
- Enhance some comments here and there.
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: Catch unsupported command before sending to chip
Labels: Milestone-1.6.x
Actually, libnfc support PN531, PN532 and PN533 NFC chips, but the devices does not the same features. e.g. PN531 does not support ISO14443B modulation.
It should great to catch theses unsuported commands before sending to chip in order to prevent a chip error.
- New API functions: nfc_strerror(), nfc_strerror_r() and nfc_perror();
- Drivers now have a reference to chips callback methods;
- Rename -pn53x_err2string to pn53x_strerror and add it to pn53x_callbacks_list.
- 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.
