| Abstract: | Taklng the 1 -Wire bus digital thermometer as an example,the hardware configuration,the operating sequence and timing graphic of DS18B20 are introduced in this paper. Combining the practical application,a measuring system of AT89C2051 with the DS18B20 is designed and a concrete programming method is offered. At last ,the problem to be noticed during the design phase are shown. |
