写一个单片机的跑马灯的C代码
时间: 2024-05-15 11:18:15 浏览: 13
好的,下面为您呈现单片机跑马灯的C代码:
```
#include <reg51.h>
void delay(unsigned int t) //延时函数
{
unsigned int i, j;
for (i = 0; i < t; i++) {
for (j = 0; j < 125; j++) {
}
}
}
void main() {
unsigned char led_temp; //8个灯的状态
unsigned char i;
while (1) {
led_temp = 0x01; //第一个灯亮起
for (i = 0; i < 8; i++) {
P0 = led_temp; //输出灯的状态
delay(200); //延时
led_temp <<= 1; //将灯的状态左移一位
}
}
}
```
注:此代码在8051单片机下编写,具体细节以及器件和外设的选择可以根据实际情况进行调整和修改。
