温度传感器DS18B20的时序分析与实现
Timing Analysis and Implementation of Temperature Sensor DS18B20
摘要
Abstract
This paper introduces the communication mode,internal structure and instruction system of DS18B20 temperature sensor,and uses the timing node analysis method to deeply analyze the initialization timing,writing data instruction timing and reading data instruction timing of the sensor,thus revealing the working principle of DS18B20.Based on the results of timing node analysis,a temperature data reading program is developed and loaded into the single-chip microcomputer chip in Proteus for simulation operation.The experimental results show that the LCD1602 screen successfully displays the temperature data consistent with the DS18B20 setting value,which verifies the feasibility and rationality of the timing node analysis method,and lays a foundation for further research on other types of sensors.关键词
