单片机C语言程序方案实训例——+Proteus仿真(前题)

单片机C语言程序设计实训100例

——基于8051+Proteus仿真

01 闪烁的LED /*名称：闪烁的LED

说明：LED按设定的时间间隔闪烁 */ #include

#define uchar unsigned char #define uint unsigned int sbit LED=P10。 //延时

void DelayMS(uint x> { uchar i。 while(x--> {

for(i=0。i<120。i++>。 } }

//主程序 void main(> {

while(1> {

LED=~LED。 DelayMS(150>。 } }

02从左到右的流水灯 /*名称：从左到右的流水灯 说明：接在P0口的8个LED 从左到右循环依次点亮，产生走 马灯效果 */ #include #include #define uchar unsigned char #define uint unsigned int //延时

void DelayMS(uint x> { uchar i。 while(x--> {

for(i=0。i<120。i++>。 } }

//主程序 void main(> { P0=0xfe。 while(1> {

P0=_crol_(P0,1>。 //P0的值向左循环移动 DelayMS(150>。 } }

038只LED左右来回点亮 /*名称：8只LED左右来回点亮

说明：程序利用循环移位函数_crol_和_cror_形成来回滚动的效果 */ #include #include #define uchar unsigned char #define uint unsigned int //延时
