【摘要】 基于ARM处理器的32位嵌入系统具有高速和大容量的数据处理能力,如何设计ARM与主机设备或系统的通信接口,成为嵌入式系统设计的一大问题。本文阐述了嵌入式系统的概念及嵌入式通信系统的结构。给出了在一个裁剪的uC/OS-II操作系统环境下实现系统与主机通信的下位机程序,方案有较高参考价值。更多还原

【Abstract】 The processing speed and capability of 32bit embeded system based on ARM procesor is very high and powerful, how to design the communication interface between ARM processor and host or other system, becomes a question of embeded system design. This article explain the concept of embeded system and the architecture of embeded communication system, brings out a design of a communication program based on uC/OS- II. So this design is worthful to refer.更多还原
