Abdul, do you know what version of SW3693.zip you downloaded? Current won't build cleanly on Raspbian Jessie June 2017.

That version of SW3693 does not compile cleanly for me on raspian jessie. Errors in example 5. Rest of build is OK.

The problem lies in example 5. sDiscLoop.sTypeVTargetInfo causes compile errors.

Looks like an issue with how include switches are set when building on and for a Pi with a nfs-explorer board.

Trying to untangle without going deep down a rabbit hole.

Hi hadifikri

Thank you very much for your support!

Hi julia-rakitina,

I've uploaded some of my test code here https://hadifikri@gitlab.com/hadifikri/nxp-explorenfc.git. It has some basic function of reading and writing and changing any sector authentication keys.

B.t.w, I'm still using the old library from 2 years ago I've provided some instructions there to get you up to speed...

Regards,

Hi Julia,

you can find all required and up to date resources at

NFC Reader Library|NXP

The software you need is NFC Reader Library for Linux. Make sure to download version 4.040.05.011646.

The corresponding documentation that describes how to get started is AN11802: NFC Reader Library for Linux Installation Guidelines.

Hope that helps,

Michael

Dear hadifikri, I appreciate your answer.

I am experienced python/Java/javascript programmer and it is my new challenge with C, before I used Arduino boards sometimes.

Could you please provide some details? What IDE should I use? How to run this examples? I found SW3693 README but it is not for EXPLORE-NXP, asks for LPCXpresso IDE...

I feel stupid to ask such noob questions , but nobody knows everything

Thank you in advance

The library that I used with my pi (2 and 3) was downloaded from nxp website. You can get it from http://www.nxp.com/documents/software/SW3693.zip look for folder NxpNfcRdLib. I surely hope the library support has improved over the years.

Thank you very much for your response!

And library is https://github.com/christianeisendle/nxprdlib-kernel-bal as I understand?

In order to set the password/authentication keys, all you have to do is write the keys to the "Sector Trailer" for every sector that you wish to protect. Each sector trailer (Block 3 of every sector) have <Key A><Access Bits><Key B> entries. You may set the password just as how you write to any block.

1) Activate the tag : phpalI14443p3a_ActivateCard(..)

2) Initiate the tag : phalMfc_Sw_Init(...);

3) Authenticate the tag with the current keys : phalMfc_Authenticate(...);

4) Write the Sector Trailer: phalMfc_Write(...);

Caution:

If you wrongly set the access bit, you might brick the tag for good.

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

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.

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

----------------------------------------------------------------------------------------------------------End Function-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Please expert help me solv this.

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

Hi,

I would like to write this card:

Mifare 1k S50 IC 13.56MHz

Hi,

which NFC Tag/Card are you talking about?

Michael

RE: NXP - EXPLORE-NFC

Former Member — Wed, 19 Mar 2014 07:30:02 GMT

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 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
