基于信息家电智能终端无线通信模块的设计

Design of Wireless Communication Module in Intelligent Terminal of Information Appliance

文章设计了由性价比高的nRF905单片射频发射器芯片和P87LPC764单片机组成的智能终端使用的嵌入式无线通信接口,该接口向低端支持I2C、SPI、UART或以并行接口形式为家电控制器扩充通信接口;向高端则通过nRF905以无线通信方式与家庭无线网关连接,实现了家庭网络控制器和智能信息家电的无线数据传输,为扩充家电设备控制器的通信接口提供一条新的途径。

Traditional appliance products can＇t be controlled flexibly.A design of wireless communication interface in the embedded information appliances by using P87LPC764 MCU and RF905 wireless module is introduced.The interface can support I2C,SPI,UART or parallel interface down to the under layer to expand the communication interface for the appliance controller,and link up to the home wireless gateway with RF905 wireless module.It provides a new approach to realize data transfer between the embedded network and IA.
