给你段程序吧nn*------------------------------------------------n 读取温度n------------------------------------------------*/nunsigned int ReadTemperature(void)n{nunsigned char a=0;nunsigned int b=0;nunsigned int t=0;nwhile(Init_DS18B20()); //检测初始化是否成功nWriteOneChar(0xCC); // 跳过读序号列号的操作nWriteOneChar(0x44); // 启动温度转换nDelayMs(10);nInit_DS18B20();nWriteOneChar(0xCC); //跳过读序号列号的操作 nWriteOneChar(0xBE); //读取温度寄存器等（共可读9个寄存器） 前两个就是温度na=ReadOneChar(); //低位nb=ReadOneChar(); //高位nb<<=8;nt=a+b;nreturn(t);n}
