RFID interfacing with AVR microcontroller (ATmega16) using interrupts

[mirza]

hi

i had this project of u long time ago by chance i got a RFID so i implemented this circuit of u but i have a problem first i made this on atmega 16L and then i made configs with nothing but ext osc while programing and then i made the circuit so it is running so well but when i passed the card in front of rfid it resets the id code but shows code with random characters like ****>><<777&# like this but not as such these characters so it is updating on the other card but still not exact code kindly tell me did i have done somthing wrong or else

i used jsxzlz rfid reader and used its pins TX on the RX of db9 and PC pin onTX of DB9 should i upload the picture too

kindly tell me

Hi
You now have problems the software? Or the hardware?

i wrote this earlier i m receiving random letters on lcd instead of actual card code it seems nothing wrong with hardware it is perfectly working so tell me is ur circuit is compatible with jsxzlz rfid or should i use different 1 coz card’s code is random characters

Make the following adjustments

 

Bit per Second 9600

Data bits 8

Parity NONE

stop bits 1

 

 

CKSEL FUSEES : INT,RC 8MHZ
