18B20数字温度显示系统
主机控制DS18B20完成温度转换必须经过三个步骤:初始化、ROM操作指令、存储器操作指令。必须先启动DS18B20开始转换,再读出温度转换值。本程序仅挂接一个芯片,使用默认的12位转换精度,外接供电电源,读取的温度值高位字节送WDMSB单元,低位字节送WDLSB单元,再按照温度值字节的表示格式及其符号位,经过简单的变换即可得到实际温度值.

This procedure is only attached a chip, using the default 12-bit conversion accuracy, an external power supply, read the temperature value high byte sent WDMSB unit and the low byte to send WDLSB of units in accordance with the temperature-byte format and representation the sign bit, after a simple transformation can be obtained by the actual temperature.
