摘要
以基于LPC2210微控制器的嵌入式系统为例,给出了一个完整的嵌入式系统软件架构方案.设定了存储器的访问方式,设计了软件的4层结构:启动及模式规划层、硬件驱动层、操作系统层和用户应用程序层,给出了系统的存储器分配方案.规划了程序按文件系统存放的框架,特别说明了其中头文件的设计.提供了一套具有工程应用价值的嵌入式系统开发方案.
Basing a embedded hardware system on LPC2210, this paper develops a scheme for constructing a software system. It consists of a setting of storage allocation and four software layers which are layer of startup and mode setting, layer of hardware driving, layer of operation system and layer of application for user. Image region allocation in the memory map has been described. A files frame designed to store program files. Especially the head files＇ program and storage have been explained in detail. This software structure provides a useful engineering application template.
