ST / Mbed 2 deprecated NFC01A1_Demos

This application provides a set of demos with X-NUCLEO-NFC01A1 expansion board.

Dependencies:   NDefLib X_NUCLEO_NFC01A1 mbed

Fork of X-MBED-NFC1 by Giovanni Visentini

This application provides a set of demos with X-NUCLEO-NFC01A1 expansion board.

The available demos are:

  • SAMPLE_WRITE_URL: write a tag with the ST home page URL
  • SAMPLE_COUNT_CLICK: create a custom tag to count and report the user button clicks.
  • SAMPLE_WRITE_AND_CHANGE_ALL: write a tag with all the supported records and update the tag contents when the user button is pressed.
  • SAMPLE_LOCK_TAG_CONTENT: use the M24SR component API to set the NFC tag as read-only.

To enable the different demos comment/uncomment the SAMPLE_* macros provided in main.cpp .
