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.
- Initialize the device right after pn53x_init() instead of pn53x_initiator_init().
- Turn on LED1 when initialized
- Switch On/Off LED2 on Activation/Desactivation of the field.
- 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)
Update issue 114
Status: Fixed
Owner: yobibe
This workaround allow to use PN533 USB (like SCL3711) without toogle bit issue (on OSes that care about this toogle bit: e.g. GNU/Linux, MacOS).
libfreefare tests suite now works as expected, enjoy!
New issue
Summary: Implement the abort mechanism (PCD->PICC ACK)
Currently, this issue is motivated by the need to reconnect to the device after a failure: ie. Issue 114.
BTW, this feature could also be useful to break an infinite polling or to cancel a previously sent command.
While here, rename the pn53x_transceive_callback() function to
pn53x_transceive_check_ack_frame_callback() to make it more obvious what it is
supposed to do.
- 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.
New issue
Summary: Make sending ACK on message transmission skipable.
Owner: rtartiere@il4p.fr
Cc: rtartiere@il4p.fr
Status: New
I guess that for performance reasons, some advance users would prefer to skip
sending the non-mandatory ACK on data transmission. They may also perform a
quicker check of the ACK returned by the chip after sending the command and
before receiving the response (not sure about this one).
It will probably be a ./configure option disabled by default that allows some "shortcuts" to perform NFC hacking.
