Hello to pcbheaven's readers once more!!!!!In the following pages i will present you an RFID reader connected to a pic microcontroller.The pic microcontroller is the pic16LF1939 from microchip and the Rfid reader is the MiniProx 5365 from HID global Secure Identity Solutions.Their datasheets are able to be downloaded from here and here.
The pic runs at 16mhz internal clock speed and the oscillation frequency of the Rfid reader is at 125mhz.The communication between the pic and the reader is accomplished through the wiegand protocol.I will provide extra info of how this protocol works on the reference section.
