NFC

Powered by NT3H2111, the EXT4 board offers users more IoT options through NFC pass-through mode.

There are two interfaces of NT3H2111_2211 to access EEPROM, one is NFC and another is I2C. The NFC interface should be used by Android/iOS phones and the I2C interface should be used by EXT4. To exchange the payload between phones and EXT4, we should use the pass-through mode which need focus on Configuration registers, Session registers and SRAM.
