An Arduino library for the ST25DV64KC Dynamic NFC/RFID Tag.
With this library, you can:
- Write WiFi credentials to the tag using your smart phone and then have your Arduino board read them via I2C
- Log data from your Arduino project into the tag's EEPROM memory and then read it back with your smart phone - even while your Arduino board is asleep or powered off!
- Configure or update your project's keys, usernames or passwords securely and easily using contactless near field communication
- Provides a comprehensive set of methods to:
- Read and write the tag's user memory
- Adjust the size of the four memory areas
- Change the I2C and RF passwords and read/write protection
- Enable RF detection and Energy Harvesting
- Includes enhanced methods to:
- Write the tag's Capability Container (CC) File
- Read and write multiple NDEF URI records
- Read and write multiple NDEF WiFi records
- Read and write multiple NDEF Text records
