以下是一个单片机间隔点亮一LED灯的C语言程序，以8051单片机为例：cCopycodeinclude//包含了ATC51的寄存器定义voiddelay(unsignedintxms)//延时函数，xms为要延时的毫秒数{unsignedinti,j;for(i=xms;i...
数码管显示路灯亮的时间是一个常见的应用场景，可以通过单片机来实现。下面是一个简单的C语言程序示例，用于控制数码管显示路灯亮的时间。```cincludesbitD1=P2^0;//定义数码管引脚sbitD2=P2^1;sbit...
voiddelay(void)//两个void意思分别为无需返回值，没有参数传递。{unsignedinti;//定义无符号整数，最大取值范围65535。for(i=0;i<20000;i++)//做20000次空循环。;//什么也不做，等待一个机...
include<reg51.h>voiddelay(void){unsignedinti,j;for(i=0;i<200;i++)for(j=0;j<1000;j++);}voidmain(void){while(1){P3=0xfe;//第一个灯亮delay();//延时P3=0xfd;//第二个灯亮delay();...
