Help with PN5180 card emulation mode

[tsotnek]

Hello everyone,

So, I am doing a custom project which includes a PN5180 IC and my task is to emulate a type A 14443 card. I want to read its UID and write to it some data from smartphone.

My procedure to setting it as a card emulation mode is as following:

1. write 1 in EEPROM addresses 0x58 & 0x51

2. loadRFCONFIG as  ISO 14443-A PICC with tx and rf conf 0x14 and 0x94 

2. activate autocoll :

      sendBuf[0] = PN5180_SWITCH_MODE;
      sendBuf[1] = 0x02; // mode 2 = autocoll
      sendBuf[2] = 0x01; // RF technologies
      sendBuf[3] = 0x02; // autocoll mode 0
      RFID_SSPSendAndReceiveBuf (sendBuf, 4, NULL, 0);

4. Check for IRQ status card_activated_IRQ, however this irq is not set. also when bringing smartphone to the device the only IRQ that gets set is RFON_DET_IRQ_STAT & RFOFF_DET_IRQ_STAT. 

The smartphone has no reaction whatsoever when bringing it close to the device.

Please help me if you know anything or can provide any type of advice or guidance.

Thank you in advance

Hello!

I'm not going to use the library and the link you posted do not provide any source code.

I need to implement the autocoll function from scratch so please provide more info. 

Thanks
