NXP - EXPLORE-NFC

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

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

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.

Thank you very much for your response!

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

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.

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

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

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 hadifikri

Thank you very much for your support!

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.

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