摘　　要：介绍了无线通信芯片CC2420的工作原理和主要特点,在此基础上设计了与AT-mega128的硬件接口电路。CC2420工作在从机模式,单片机工作在主机模式,通过SPI(串行外围接口)读/写CC2420缓冲器内的数据。给出了单片机控制CC2420工作所需的寄存器控制接口设计,为利用CC2420实现无线传感器网络通信做好前期准备。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.
