1、单片机软件实现数码时钟，可以用 proteus7.12 仿真，也可以，做成实物后 18B20 会读取出错，或者给我发邮件给你一份实物能用的（proteus7.12 仿真 18B20 会读取出错） ，电路图不清晰处理方法，将电路图另存为图片格式，或者直接放大即可。http:/ #include #include#define uint unsigned int#define uchar unsigned charuchar hour,min,sec,sec1=0;/时钟函数uint time_ms=0;uchar time_sec=0,time_min=34,time_hour=9;uchar
