| Abstract: | This paper introduces the operation principle and main characteristics of wireless IC CC2420, followed by the design of interface circuit with micro controller ATmega128. Microcontroller reads and writes buffer data in CC2420 through SPI interface. CC2420 works in slave mode and ATmega128 in master mode. The paper also gives a brief scheme of registers setting in CC2420, which lays the foundation of designing wireless sensor network. |
