            TH=read18b20(); //接着读的是温度值高位
            TN=TH*16+TL/16;    //实际温度值=(TH*256+TL)/16,即：TH*16+TL/16
                                       //这样得出的是温度的整数部分,小数部分被丢弃了
      TD=(TL%16)*10/16;

      display_temp1(TN); //显示温度的整数部分
      display_temp2(TD); //显示温度的小数部分
      }
      }
}
求大神指点一下按键总是调不好
