M24SR64-Y

Arduino library to support the dynamic NFC/RFID Tag IC dual interface M24SR64-Y.

API

• M24SR(const uint8_t, TwoWire *, gpoEventCallback, const int, const int): class constructor
  Params I2C address of the component
  Params pointer to the I2C instance
  Params pointer to a gpoEventCallback called when the gpo pin status changes
  Params gpo pin number
  Params RF disable pin number

• begin(void *): initializes the device
  Params not used
  Returns M24SR_SUCCESS if no errors

• writeTxt(const char *): write text TAG
  Params pointer to the text to write
  Returns true if no errors

• readTxt(char *): read text TAG
  Params pointer to the text to read

• writeUri(const char *): write URI TAG
  Params pointer to the URI to write
  Returns true if no errors

• readUri(char *): read URI TAG
  Params pointer to the URI to read

• writeAAR(const *): write AAR TAG
  Params pointer to the AAR to write
  Returns true if no errors

• readAAR(char *): read AAR TAG
  Params pointer to the AAR to read

• writeURIMail(const char *, const char *, const char *): write URI Mail TAG
  Params pointer to recipient
  Params pointer to the mail subject
  Params pointer to the mail body
  Returns true if no errors

• readURIMail(char *, char *, char *): read URI Mail TAG
  Params pointer to recipient
  Params pointer to the mail subject
  Params pointer to the mail body
  Params pointer to the URIMail to read

• writeSMS(const char *, const char *): write SMS TAG
  Params pointer to recipient
  Params pointer to the SMS body
  Returns true if no errors

• readSMS(char *, char *): read SMS TAG
  Params pointer to recipient
  Params pointer to the SMS body
  Params pointer to the SMS to read

• writeMime(const char *, const char *, const uint8_t): write mime TAG
  Params pointer to mime type
  Params pointer to data
  Params data length
  Returns true if no errors

• readMime(char *, uint8_t *, uint8_t *): read mime TAG
  Params pointer to mime type
  Params pointer to data
  Params pointer to data length

For the other functions the documentation is available on www.st.com.

Known limitation

The size of a TAG is limited to 246 bytes. This limitation is due to the Iblock command on the M24SR device (protocol + payload = 255 bytes).

Examples

• WriteAAR: writes a AAR (Android Application Record) tag on the device. It opens an application on your smartphone.
• WriteMime: writes a mime tag on the device. It records a define type of data.
• WriteSMS: writes a SMS tag on the device. It records a SMS body and a recipient phone number
• WriteText: writes a text tag on the device. It records a simple text message.
• WriteURI: writes a URI tag on the device. It records an URI.
• WriteURIMail: writes a Mail tag on the device. It records a mail with the recipient, the subject and the body of the message.
