摘　　要：介绍了一个基于nRF2401的短距离无线通信系统,分析了该系统的硬件电路、软件设计和通信原理。nRF2401在单片机STC89C516RD+的控制下,工作在突发模式,可以实现全双工通信。在显示方面,本系统采用128×64点阵液晶显示器,从而实现了很好的人机界面。为了实现两个移动台可以收发汉字短信,设计中加入了中文输入法,字库则存储在有64 kB片内Flash存储器的STC89C516RD+中。A wireless short-distance communication system based on nRF2401 and SCM STC89C516RD ＋ is introduced. The system＇ s hardware, software and circuits are analyzed, as well the theory of communication of the system. The system is functioning in the ShockBurst mode of nRF2401, which is controlled by MCU STC89C516RD ＋ and it can realize full duplex communication. In displaying, this system uses LCD12864 which can display Chinese characters in real-time, and show on the LCD. The Chinese characters storehouse is stored in the MCU STC89C516RD ＋ which has 64 kB ROM on chip.
