Hello, I’m new in RFID and don’t know how to make RFID reader read. Can you help me ? How RFID reader read with freerunning mode from ATMega8’s command through serial ?
Note: I use RFID Kanda Starter Kit.Thank you..
hello sciencetronot…
i here i am sending you some of links related to RFID…
What is RFID how does it works??

RFID interfacing using AVR interrupt concepts…
the above two links for AVR interfacing with RFID is using ATmega16 but the same concept is applied on ATmega8… go throught these links… an if face any problem in future let us know we will try to solve that out….
Hey all,
The interfacing of an RFID reader with AtMega8535 boggled me for 2 months until i realised that the only flaw was regarding the connections.
Please note the connections of the pins. Its really tricky. If u know this weird conventions of MAX232 then interfacing of the reader is very easy. Otherwise it would be really difficult to realise the gamble.My friend revealed it to me and am sharing here so that others dont face the same problem.
Happy engineering!
cheers!When you swap an rfid tag on to an rfid reader, it just receives the secret number inside the tag and send to its serial port. From there you can convert it using serial to ttl converter ( MAX232 ) and receive it into the microcontroller and store it in an array. Then you can compare it with any predefined array. That is the basic idea.
