Public Member Functions

 NTAG_I2C (IntPtr ftHandle)
 Instanciate the NTAG_I2C. The ftHandle parameter must be a valid handle to the FTDI's FT2XX DLL, opened against the FT42222 interface connected to the NTAG.
 
void PrintLastError ()
 Print the last error to the console.
 
bool ClearSession ()
 Reset the session flags to accept another NFC reader/writer.
 
bool WriteConfiguration ()
 Write the configuration registers according to the NTAG I2C specification.
 
bool EnablePassthroughNfcToI2c ()
 Enable the SRAM passthrough NFC->I2C for the current session.
 
bool EnablePassthroughI2cToNfc ()
 Enable the SRAM passthrough I2C->NFC for the current session.
 
bool ReadSessionRegister (byte register, ref byte value)
 Read one of the NTAG I2C's session registers. Return false on error.
 
int ReadSessionRegister (byte register)
 Read one of the NTAG I2C's session registers. Return -1 on error.
 
bool Read16 (byte addr, ref byte[] data)
 Read data from the NTAG I2C. Warning, addr is related to the I2C mapping, which is different from the NFC mapping.
 
byte [] Read16 (byte addr)
 Read data from the NTAG I2C. Warning, addr is related to the I2C mapping, which is different from the NFC mapping.
 
bool Write16 (byte addr, byte[] data)
 Write data into the NTAG I2C. Warning, addr is related to the I2C mapping, which is different from the NFC mapping. data shall be a 16-byte buffer.
 
bool Erase16 (byte addr)
 Write empty data into the NTAG I2C. Warning, addr is related to the I2C mapping, which is different from the NFC mapping.
 
void DumpMemoryContent ()
 Read all the data from the NTAG I2C and show them onto the console.
 
void DumpSessionRegisters ()
 
TLV ReadResponse ()
 Read the response from the remote device (if some) through the NTAG_I2C's SRAM.
 
bool ClearResponse ()
 Clear the NTAG_I2C's SRAM.

Properties

bool Valid [get]
 Return true if the object is valid, i.e. if a NTAG I2C chip has actually been found on the I2C bus.
 
byte [] UID [get]
 Return the serial number (or UID). It should be in the form "04 <5 bytes> 80" for a genuine NXP NTAG I2C.
