基于ISD4003的车道偏离警示系统语音报警实现

Voice Warning of Lane Departure System Based on Singlechip of ISD4003

介绍了车道偏离警示系统的语音报警实现方法和MC9S12DP256单片机与ISD4003语音芯片之间的SPI串行通信原理,给出了MC9S12DP256单片机与ISD4003语音芯片的电路连接及软件控制,实现了车道偏离警示系统的组合放音的设计。

This paper introduces the realization method of lane departure warning system and the principle of SPI serial communication. It presents circuit diagram and software between MC9S12DP256 and voice warning chip of ISD4003. So that it completes design of assembled playback of lane departure voice warning system very well.
