Hi all.
I'm new on this forum.
I have question for RFID reader 125kHz.
In my application (AVR) use EM4095 IC for read and decode TAG.
Now I have small reader where is PIC MCU and small board for read decode TAG to TTL for MCU.
There is used 16MHz crystal and 74HC393 , 4049 and 74HC04 (+ many passive component) .
question is how it work ?? how I can read data and decode it?? there is possible to use only 3 pin (for small RFID board) VCC, GND and decode data out, no other need. In my application used EM4095 I need minimum 2pin, and read distance using EM4095 is smaller then use reader with 4069 .
how I can read this data ??
thanks all.
