hello all.
i'm working with NT3H2211 Tag and RC522 as a reader.
i'm trying to communicate from PC (reader) to MCU (NT3H2211 - i2c bus).
the PC write command. -> MCU decode it and send answer.-> PC read the answer and so on.
1. PC write command - working good
2. MCU get the command and decode it - working good
3. MCU send answer - working good
4. from i2c perspective -> NC_REG=7Ch , NS_REG=29h - working good
5. from NFC perspective -> NC_REG=7Ch , NS_REG=00h <--- NOT working!!!!!!
i dont understand y NS_REG is always 0x00. when from i2c i read 0x29!!
please help.
Hello,
Please make sure that you are accessing the session registers correctly from NFC Perspective. The session registers are available from page 0xEC to 0xED. The NS_REG, is in Byte 2 of page 0xED. For more information, please refer to Table 12. of the data-sheet:
