need help in RFID interfacing to 89c52

[ud23]

hi i am using chipcon cc2500 i wrote code for that but not working any one have working code to transmit and receive continuous data . and if have instillation register sequence .pls i need it urgent ...........

 

[klystron]

Tell us more about your application

i would like to use cc2500 as transceiver and used as slave with 89c52 need sent or receive data if it present on cc2500 and take that data in pic controller and need operate relays

this is my code but it doesnt working is there any modification or correction needed please help me
