单总线是一种新型总线标准,仅通过一条数据线便可以完成主机对多个器件的通信和控制。本文简述了单总线技术特点、单总线协议及单总线间的通信方式,分析单总线器件的结构、操作和信息访问的机理,介绍其软件开发环境和应用系统的设计方法及软件框图。 Single-bus is a new type of bus standard that enables the host to communicate and control multiple devices with just one data line. This paper describes the characteristics of single-bus technology, single-bus protocol and single-bus communication between the single bus device structure, operation and information access mechanism, introduced its software development environment and application system design methods and software block diagram.
