Detailed Description

This class represents a NFC target (either a remote target when the local controller in in initiator mode, or a target connected through a wired connection).

A target can be a NFC tag/card, a NFC-enabled phone or other NFC device capable of modulating a RF field.

Constructor & Destructor Documentation

NFCTarget ( const Span< uint8_t > &  buffer )

Create a NFCTarget.

Parameters:
[in]buffera bytes array used to store NDEF messages

Member Function Documentation

void build_ndef_message ( ac_buffer_builder_t &  buffer_builder ) [protected, inherited]

Build NDEF message.

Parameters:
[in,out]buffer_buildera buffer builder in which to create the NDEF message. The backing buffer is guaranteed to be continuous.

Definition at line 44 of file NFCNDEFCapable.cpp.

virtual void erase_ndef_message (  ) [pure virtual]

Erase the NDEF message in the target.

on_ndef_message_erased() will be called on completion.

Implemented in NFCEEPROM.

virtual bool is_ndef_supported (  ) const [virtual, inherited]

Check if this instance actually supports NDEF content.

Returns:
whether NDEF content is supported

Reimplemented in Type4RemoteInitiator.

Definition at line 55 of file NFCNDEFCapable.h.

ndef_msg_t * ndef_message (  ) [protected, inherited]

Retrieve underlying NDEF message instance.

Returns:
pointer to NDEF message instance

Definition at line 77 of file NFCNDEFCapable.cpp.

void parse_ndef_message ( const ac_buffer_t &  buffer ) [protected, inherited]

Parse a NDEF message.

Parameters:
[in]buffera buffer containing a NDEF message

Definition at line 33 of file NFCNDEFCapable.cpp.

virtual void read_ndef_message (  ) [pure virtual]

Read a NDEF message from the target.

on_ndef_message_read() will be called on completion.

Implemented in NFCEEPROM.

virtual void write_ndef_message (  ) [pure virtual]

Write a NDEF message to the target.

on_ndef_message_written() will be called on completion.
