* 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.)
|
|
* Released into the public domain.
|
|
*
|
|
* Sample program showing how to read data from a PICC using a MFRC522 reader on the Arduino SPI interface.
|
|
* Pin layout should be as follows:
|
|
* Signal Pin Pin
|
|
* Arduino Uno MFRC522 board
|
|
* -----------------------------------------
|
|
* Reset 9 RST
|
|
* SPI SS 10 SDA
|
|
* SPI MOSI 11 MOSI
|
|
* SPI MISO 12 MISO
|
|
* SPI SCK 13 SCK
|
|
*
|
|
* The reader can be found on eBay for around 5 dollars. Search for "mf-rc522" on ebay.com.
