The Searching Algorithm of the Sequential Numbers of DS18B20s on 1-wire-bus Structure

LIU Xiao-yang,ZHOU Yan-tao (College of Electronic and Information Engineering,Hunan University,Changsha 410082China)  
This paper discussed the searching algorithm of the sequential numbers of the 64-bits of multiple digital temperature sensor named DS18B20 based on the 1-wire-bus structure,proposed a new searching algorithm depending on the searching features of DS18B20,and provided the detailed flow chart.Finally,the algorithm was verified.This algorithm,pithily programmed and running-time steadily,is better organized compared with the traditional algorithms.Not only does it save the required memory space,but also it has more practicality in engineering with its high performance.
