基于I2C总线单片机暖水锅炉测温系统实现:摘要：温度测量是工程控制领域常见的一种情况，本文介绍了一种基于I2C 总线的单片机暖水锅炉的测温方法，主要以MCS—51单片机的汇编语言为软件开发工具；主要实现了对锅炉上下水的温度采集、存储及显示等功能。使用I2C 总线为串行扩展总线，使得程序设计部分大为简化。Abstract: Application of temperature survey is very universal in Control engineering, Thisarticle introduced one kind of temperature survey system take the assembly languages of mcs-51 as the software development tool, the mainly functions are temperature survey, the memory and the demonstration. moreover, this design take the I2C Bus as the serial expansion Bus, thisprogramming just uses these characteristics of I2C Bus to make the design of program is verysimplification.Key words: MCU; I2C Bus; temperature survey
