Introduction: ATMEL AT89S52 + RFM70 for Wireless Data Transmission !

I have interfaced RFM70 a 2.4GHz RF Module with ATMEL's AT89S52 microcontroller and used it for wireless communication. 

Microcontroller i have used :- ATMEL- AT89S52.
Programmer for ATMEL:- TOPWIN Universal Programmer.
RF Module:- RFM70 from HOPE RF.
