This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the ST25DVxx-series dynamic NFC/RFID tag ICs with integrated EEPROM.
IMPORTANT: This software is meant to be used with the spin-standard-library (P8X32A) or p2-spin-standard-library (P2X8C4M64P). Please install the applicable library first before attempting to use this code, otherwise you will be missing several files required to build the project.
- I2C connection at ~25kHz (P1: bytecode-based I2C engine), 1MHz (P1: PASM-based I2C engine, P2)
- Read/write to the embedded EEPROM over I2C (uses memory.md API
- Present, change security session password (I2C)
- Read serial number
- Read RF individual area R/W and password policies
- Read lock flags
- Enable/disable energy-harvesting feature
