Desfire/MFRC522 library and command list?

[kjlowe]

Hi everyone,

I have a MFRC522 chip and I am trying to write files to and read the UID of a Desfire EV1 card. I am using a ported version of this library:

https://github.com/ljos/MFRC522/blob/master/MFRC522.cpp

The library works fine for MIFARE Classic but I am having problems with Desfire EV1. The Desfire EV1 datasheet (MF3ICDx21_41_81) does not have detailed list of commands and responses. On the Q&A page it says "NXP provides reader libraries for all our reader chips supporting every MIFARE product. However, libraries for security products like MIFARE DESFire and MIFARE Plus can only be obtained a valid NDA"

http://www.mifare.net/en/micommunity/qa/

Where can I request an NDA document and get those libraries? Where can I get a detailed datasheet of Desfire EV1 commands?
