Hi Mauro,

the main difference between the PN512 and the PN532 is that the PN532 is combined with a microcontroller. So if you are using the PN532 with the Raspberry Pi, you can not directly talk to the NFC reader IC but to the firmware on the microcontroller if the reader IC.

If you are using the Explore-NFC with the Raspberry Pi, you can talk directly to the PN512 over the SPI interface. That offers more flexibility in using the reader IC. To make working with the PN512 more comfortable, NXP provides a reader library that is included in the example projects which can be downloaded.

The PN512 is NFC Forum complaint, the PN532 is not.

The PN512 is supported by the NXP Reader Library (sources are available for download), the PN532 is not supported.

Both ICs are supporting the same tags.

Best Regards,

Michael

Hi Michael,

I have PN512 and I use the Reader Library. I would like to change the key of the card. Can I do with this IC or not because I didn't find any solution for that.

Thanks

Grill

Hi,

which NFC Tag/Card are you talking about?

Michael

Hi,

I would like to write this card:

Mifare 1k S50 IC 13.56MHz

Grill

Yes, that's possible.

An example project about how to read/write Mifare Classic cards can be found here.

Just download the project "PNEV512BPNEV512B MIFARE Classic Project for LPC1227 You can find the example in the main function of the main.c It uses the same library as the provided Raspberry project does

Michael

Thanks. I'll try this I hope it'll work

Grill.

Dear friends.

I am  write a C library using SPI communication for interface the Board NFC EXPLORE PN512 with a micocrontroller 8 bit, 16 bit or 32 bit. This because lot off pleople dont has Raspeberry or prefere use this Board with another MCU, like in my case.

After one week working in this projects I can manager the NFC EXPLORE register, for exemaple write and read the FIFO BUFFER, clear the configuration, transmitte data to RF anntena.

Now I need any help to solve the last problem that is: Cannot send data to MIFARE card to read the UID or other data that is store in the card EEPROM.

Below is my code:

// THIS LINES OF CODE CONFIGURE THE DEVICE TO ENABLE RF ANTENA AND

EXPLORE_NFC_PN512_ControlReg(0x05);

  EXPLORE_NFC_PN512_TxAutoReg();

  EXPLORE_NFC_PN512_RxThresholdReg();

  EXPLORE_NFC_PN512_RFCfgReg();

  EXPLORE_NFC_PN512_GsNOnReg();

  EXPLORE_NFC_PN512_TxControlReg();

  // CLEAR THE FIFO BUFFER BEFORE  WRITE THE COMMAND DO BE SEND TO RF

  EXPLORE_NFC_PN512_Clear_Fifo_Buffer();

  EXPLORE_NFC_PN512_WRITE_MB_INTO_FIFO_BUFFER(0x26);  // value write 0x26h command do quest card

// NOW SEND THE FIFO CONTENT TO ANNTENA AND WAIT FOR MIFARE CARD RESPONSE

// IN THIS PARTICULAR CASE I WAITING FOR 04h 00h

EXPLORE_NFC_PN512_Start_Send();

EXPLORE_NFC_PN512_Transmit();

EXPLORE_NFC_PN512_Transceive();

    _delay_cycles (50000);

    nBytes=EXPLORE_NFC_PN512_GetFifoLevel(); // Get FiFo level

  _delay_cycles (50000);

    receiveData=EXPLORE_NFC_PN512_READ_FIFO_BUFFER_MB();  // Read Buffer

Please expert help me solv this.

Hi Michael,

I've been using nxpRdLib in Raspberry Pi for NFC-EXPLORE to read and write on MIFARE Classic 1K for a while now. So far I managed to read and write into the tag using KEY A authentication. However I need to set KEY A as a read only KEY and KEY B for write operation. I know that I have to write the access bits to setup the behavior. My problem is I never managed to authenticate the card using KEY B at all. Is there any example using NxpRdLib that performs authentication using KEY B?

p/s : I've already successfully loaded KEY B into the phKeyStore and the KEY B is the default factory value verified using NFC Tag info (Android App).

(edit): The current access bits setup allows for read and write operation using KEY A or KEY B for NFC sector and only write operation using KEY B for sector trailers.

Regards.

Never mind, I got it.

Hi hadifikri

I need similar functionality, I have NFC-Explore and raspberry Pi2. I am giong to use Mifare Classic 1k

How to implement this?
I tried with NTAG216 cant find documentation to set a password
