这个单片机程序定义没怎么看懂，H,M,L没懂什么意思，还有就是为什么要乘100000,100...

void READS()
{
      uchar Mileage_H,Mileage_M,Mileage_L;
      delay(10);
      RADIUS=read_add(0x01);
      delay(10);
      SAFE_SPEED=read_add(0x02);

      delay(10);
      Mileage_L=read_add(0x05);

      Mileage=Mileage_H*100000+Mileage_M*1000+Mileage_L*10;
}

//写初值

      delay(10);

      delay(10);

      Mileage_M=Mileage%10000/100;
      Mileage_L=Mileage%10000%100;       */
      delay(10);

      delay(10);
      write_add(0x05,Mileage%100000%1000/10);
}
我是一个单片机小白，希望各位大佬相助一下，

程序不全。不知道为啥要这样做，可能和读取的位数有关，每次只能read_add两个字符。按照你给的代码。uchar ...

那我可以把全部程序发给你看一下吗就这里不怎么懂什么意思你的评论我觉得挺好的但是好像有什么24小时评分限制我明天再给评分谢谢了希望能回复一下实在是单片机小白想学习一下很多不懂的

这是主程序，这个程序主要用来测速，用的是光电传感器，通过定时记脉冲来进行测速，用了一个外部存储器，就是这里不怎么懂，希望大佬帮下忙，谢谢
