下面是关于DS18B20的汇编语言，我想把它翻译成C语言，哪位大侠能帮帮忙，在此先行谢过。
    命令                              功能描述                    命令代码
    CONVERT                       开始温度转换                    44H
    READ SCRATCHPAD             读温度寄存器（共9字节）              BEH
        READ ROM                    读DS18B20序列号                  33H
    WRITE SCRATCHPAD        将警报温度值写如暂存器第2、3字节         4EH
       MATCH ROM                        匹配ROM                       55H
      SEARCH ROM                        搜索ROM                       F0H
     ALARM SEARCH                       警报搜索                      ECH
    SKIP ROM                    跳过读序列号的操作                 CCH
READ POWER SUPPLY     读电源供电方式：0为寄生电源，1为外电源      B4H
