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 .
