这是关于DS18B20的读写程序,数据脚P2.2,晶振12MHZ 温度传感器18B20汇编程序,采用器件默认的12位转化,最大转化时间750微秒 可以将检测到的温度直接显示到AT89C51开发实验板的两个数码管上 显示温度00到99度,很准确哦~~无需校正!-This is about reading and writing DS18B20 procedures, data pin P2.2, crystal 12Mhz temperature sensor 18B20 assembler, using the default device 12 transformation, the largest conversion time of 750 microseconds can be detected in the temperature display to direct the development of experimental AT89C51 Two digital control panel displays the temperature 00-99 degrees, very accurate without calibration Oh ~ ~!
