* MFRC522 - Library to use ARDUINO RFID MODULE KIT 13.56 MHZ WITH TAGS SPI W AND R BY COOQROBOT.
|
|
* The library file MFRC522.h has a wealth of useful info. Please read it.
|
|
* The functions are documented in MFRC522.cpp.
|
|
*
|
|
* Based on code Dr.Leong ( WWW.B2CQSHOP.COM )
|
|
* Created by Miguel Balboa (circuitito.com), Jan, 2012.
|
|
* Rewritten by Søren Thing Andersen (access.thing.dk), fall of 2013 (Translation to English, refactored, comments, anti collision, cascade levels.)
|
|
* Extended by Tom Clement with functionality to write to sector 0 of UID changeable Mifare cards.
|
|
*
|
|
* Released into the public domain.
|
|
*
|
|
* This sample shows how to fix a UID changeable MIFARE cards that have a corrupted sector 0.
