单片机流水灯所有程序

1、#include#define uchar unsigned char/char 是字符数组#define unit unsigned intuchar num;sbit led仁PMO;void main()1 (0000 0001 )TMOD=OxO1; / 打开工作方式寄存器，选择工作方式 THO=(65536-45872)/256;TLO=(65536-45872)%6;EA=1; / 开总中断ETO=1; / 开定时器 O 中断TRO=1; /启动定时器 Owhile(1);/程序停止在这里等待中断发生void TO_time()interrupt 1TH1=(65536-45872
