AT89C51单片机流水灯c语言程序
1、首先先在proteus画出仿真图,方便仿真程序
2、下面来编写程序,先来写入头函数
3、根据自己在proteus画的图,定义一下管脚根据你的原理图进行编写
sbit p0=P1^0;
sbit p1=P1^1;
sbit p2=P1^2;
sbit p3=P1^3;
sbit p4=P1^4;
sbit p5=P1^5;
sbit p6=P1^6;
sbit p7=P1^7;
4、然后写一个延时函数,来调节流水灯的时间间隔延时时间自己定义
void mdelay(unsigned int t)
{
unsigned char n;
for(;t》0;t--)
for(n=0;n《125;n++)
{;}
}
5、下面就是主函数,包括流水灯的反复循环和j流水灯的方向
6、检查没有错误,编译一下。就可以进行仿真了
