Hello everybody,
I am working on a project in which I use a CLRC663 for NFC communication with type 2 tags. I use this library that I adapted for the RS232 communication protocol ( I just defined write_reg and read_reg functions) : https://github.com/kenny5660/CLRC663
When I try to read/ write registers as Version register or command register all works as it should. However, when I try to send the REQA protocole, I have T0 underflow IRQ and when I try to change the value in T0COUNTERVAL[HI/LO] registers nothing change and the CLRC answer me that the 2 registers are at 0x00 when I read them.
As initialisation I use CLRC663_AN1102_recommended_registers(CLRC663_PROTO_ISO14443A_106_MILLER_MANCHESTER); function and I do my REQA after.
Do you have some ideas to help me with this problem ?
Thanks in advance
Mathieu
