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.
