《基于8051+Proteus仿真》案例
第 01 篇 基础程序设计
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=P1^0;
//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);
}
}
03 8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
void DelayMS(uint x)
{
uchar i;
while(x--)
{
for(i=0;i<120;i++);
}
}
//主程序
void main()
{
uchar i;
P2=0x01;延时
while(1)
{
for(i=0;i<7;i++)
{
P2=_crol_(P2,1); //P2的值向左循环移动
DelayMS(150);
}
for(i=0;i<7;i++)
{
P2=_cror_(P2,1); //P2的值向右循环移动
DelayMS(150);
}
}
}
04 花样流水灯
/* 名称：花样流水灯
说明：16只LED分两组按预设的多种花样变换显示
*/
