摘要
本文从硬件和软件二方面,结合一个带CAN接口的强单片机PIC18F458,从实际工程应用角度来阐述一个较复杂的仪表系统工程的实现。其中较系统的介绍了PIC18f458单片机系统外围电路,单片机系统与步进仪表电机接口、与液晶显示模块接口、与小键盘扩展接口尤其重要的是单片机CAN通信软、硬件接口等五个部分。
With the powerful single chip CPU PIC18F458, we discuss an implementation of complex automobile meter system from the view of practical engineering, including both hardware and software. Also in this article, we intensively introduce the framework of PIC18F458 peripheral circuit, interface to step motor meter, interface to liquid crystal display module, extended interface to minikeyboard, as well as the important software and hardware interface of PIC18F458＇s CAN communication.
