Study on Timing Sequences of Interface Program of Digital Temperature Sensor DS18B20

摘要

DS18B20 belongs to a kind of single-bus digital temperature sensor with corresponding simple hardware circuit connection. As a result it is necessary to make use of software to provide complicated and accurate timing logical sequences to realize data transfer correctly between the sensor and host computer, and finally to ensure the accuracy of data the host receives. It is the most foundational element to provide accurate timing logical sequences making use of some kind of relatively complicated software structure for data transfer of the single-bus digital sensors.
