智能移动设备的音频通信接口设计与实现

Design and implementation of audio communication interface of intelligent mobile devices

本文基于LPC812M101 32位ARM微控制器和智能手机的音频接口,以差分曼彻斯特编码算法为核心,设计了i Phone4S智能手机与外部设备的通用型硬件通信接口,能有效地实现智能移动系统与外部物理设备间的信息互动。实验表明,该通信接口功耗低,硬件集成度高,支持i OS和Android智能移动设备,通用性好,有着良好的应用前景。

Based on LPC812M101 32-bit ARM micro controller and intelligent mobile phone audio interface, with differential Manchester encoding algorithm at the core, an universal hardware communication interface between the i Phone4 S smartphone and the external device was designed in this paper,and it can effectively realize intelligent information interaction amongst the mobile system and the external physical device. The experimental results show that this communication interface of low power consumption, high hardware integration, good generality, supporting i OS and Android smart mobile devices, has a good future prospect.
