* MFRC522.h - Library to use ARDUINO RFID MODULE KIT 13.56 MHZ WITH TAGS SPI W AND R BY COOQROBOT.
|
||||||
|
* 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.)
|
||||||
|
* Released into the public domain.
|
||||||
|
*
|
||||||
|
* Please read this file for an overview and then MFRC522.cpp for comments on the specific functions.
|
||||||
|
* Search for "mf-rc522" on ebay.com to purchase the MF-RC522 board.
|
||||||
|
*
|
||||||
|
* There are three hardware components involved:
|
||||||
|
* 1) The micro controller: An Arduino
|
||||||
|
* 2) The PCD (short for Proximity Coupling Device): NXP MFRC522 Contactless Reader IC
|
||||||
|
* 3) The PICC (short for Proximity Integrated Circuit Card): A card or tag using the ISO 14443A interface, eg Mifare or NTAG203.
|
||||||
|
*
|
||||||
|
* The microcontroller and card reader uses SPI for communication.
|
||||||
|
* The protocol is described in the MFRC522 datasheet: http://www.nxp.com/documents/data_sheet/MFRC522.pdf
|
||||||
|
*
|
||||||
|
* The card reader and the tags communicate using a 13.56MHz electromagnetic field.
|
||||||
|
* The protocol is defined in ISO/IEC 14443-3 Identification cards -- Contactless integrated circuit cards -- Proximity cards -- Part 3: Initialization and anticollision".
|
||||||
|
* A free version of the final draft can be found at http://wg8.de/wg8n1496_17n3613_Ballot_FCD14443-3.pdf
|
||||||
|
* Details are found in chapter 6, Type A – Initialization and anticollision.
|
||||||
|
*
|
||||||
|
* If only the PICC UID is wanted, the above documents has all the needed information.
|
||||||
|
* To read and write from MIFARE PICCs, the MIFARE protocol is used after the PICC has been selected.
|
||||||
|
* The MIFARE Classic chips and protocol is described in the datasheets:
|
||||||
|
* 1K: http://www.nxp.com/documents/data_sheet/MF1S503x.pdf
|
||||||
|
* 4K: http://www.nxp.com/documents/data_sheet/MF1S703x.pdf
|
||||||
|
* Mini: http://www.idcardmarket.com/download/mifare_S20_datasheet.pdf
|
||||||
|
* The MIFARE Ultralight chip and protocol is described in the datasheets:
|
||||||
|
* Ultralight: http://www.nxp.com/documents/data_sheet/MF0ICU1.pdf
|
||||||
|
* Ultralight C: http://www.nxp.com/documents/short_data_sheet/MF0ICU2_SDS.pdf
|
||||||
|
*
|
||||||
|
* MIFARE Classic 1K (MF1S503x):
|
||||||
|
* Has 16 sectors * 4 blocks/sector * 16 bytes/block = 1024 bytes.
|
||||||
|
* The blocks are numbered 0-63.
|
||||||
|
* Block 3 in each sector is the Sector Trailer. See http://www.nxp.com/documents/data_sheet/MF1S503x.pdf sections 8.6 and 8.7:
|
||||||
|
* Bytes 0-5: Key A
|
||||||
|
* Bytes 6-8: Access Bits
|
||||||
|
* Bytes 9: User data
|
||||||
|
* Bytes 10-15: Key B (or user data)
|
||||||
|
* Block 0 is read only manufacturer data.
|
||||||
|
* To access a block, an authentication using a key from the block's sector must be performed first.
|
||||||
|
* Example: To read from block 10, first authenticate using a key from sector 3 (blocks 8-11).
|
||||||
|
* All keys are set to FFFFFFFFFFFFh at chip delivery.
|
||||||
|
* Warning: Please read section 8.7 "Memory Access". It includes this text: if the PICC detects a format violation the whole sector is irreversibly blocked.
|
||||||
|
* To use a block in "value block" mode (for Increment/Decrement operations) you need to change the sector trailer. Use PICC_SetAccessBits() to calculate the bit patterns.
|
||||||
|
* MIFARE Classic 4K (MF1S703x):
|
||||||
|
* Has (32 sectors * 4 blocks/sector + 8 sectors * 16 blocks/sector) * 16 bytes/block = 4096 bytes.
|
||||||
|
* The blocks are numbered 0-255.
|
||||||
|
* The last block in each sector is the Sector Trailer like above.
|
||||||
|
* MIFARE Classic Mini (MF1 IC S20):
|
||||||
|
* Has 5 sectors * 4 blocks/sector * 16 bytes/block = 320 bytes.
|
||||||
|
* The blocks are numbered 0-19.
|
||||||
|
* The last block in each sector is the Sector Trailer like above.
|
||||||
|
*
|
||||||
|
* MIFARE Ultralight (MF0ICU1):
|
||||||
|
* Has 16 pages of 4 bytes = 64 bytes.
|
||||||
|
* Pages 0 + 1 is used for the 7-byte UID.
|
||||||
|
* Page 2 contains the last chech digit for the UID, one byte manufacturer internal data, and the lock bytes (see http://www.nxp.com/documents/data_sheet/MF0ICU1.pdf section 8.5.2)
|
||||||
|
* Page 3 is OTP, One Time Programmable bits. Once set to 1 they cannot revert to 0.
|
||||||
|
* Pages 4-15 are read/write unless blocked by the lock bytes in page 2.
|
||||||
|
* MIFARE Ultralight C (MF0ICU2):
|
||||||
|
* Has 48 pages of 4 bytes = 64 bytes.
|
||||||
|
* Pages 0 + 1 is used for the 7-byte UID.
|
||||||
|
* Page 2 contains the last chech digit for the UID, one byte manufacturer internal data, and the lock bytes (see http://www.nxp.com/documents/data_sheet/MF0ICU1.pdf section 8.5.2)
|

Renamed library from RFID to MFRC522 (RFID seemed to generic).
|
||||||
|
Register names changed to comply with datasheet.
|
||||||
|
Global defines moved into class.
|
||||||
|
All constants, functions and parameters are now commented in English.
|
||||||
|
Code refactored, most function names have changed.
|
||||||
|
Now supports ISO-14443-3 anti collission and 4/7/10 byte UIDs (cascade levels).
|
||||||
|
Added functions for MIFARE Classic Decrement/Increment/Restore/Transfer and MIFARE Ultralight Write.
|
||||||
|
New examples written.
