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 */ #includereg51.h #define uchar unsigned char #define uint unsigned int sbit LED=P10; //延时 void DelayMS(uint x) { uchar i; while(x--) { for(i=0;i120;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 */ #includereg51.h #includeintrins.h #define uchar unsigned char #define uint unsigned int //延时 void DelayMS(uint x) { uchar i; while(x--) { for(i=0;i120;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 */ #includereg51.h #includeintrins.h #define uchar unsigned char #define uint unsigned int //延时 void DelayMS(uint x) { uchar i; while(x--) { for(i=0;i120;i++); } } //主程序 void main() { uchar i; P2=0x01; while(1) { for(i=0;i7;i++) { P2=_crol_(P2,1); //P2 的值向左循环移动 DelayMS(150); } for(i=0;i7;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 */ #includereg51.h #define uchar unsigned char #define uint unsigned int uchar code Pattern_P0[]= { 0xfc,0xf9,0xf3,0xe7,0xcf,0x9f,0x3f,0x7f,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff, 0xe7,0xdb,0xbd,0x7e,0xbd,0xdb,0xe7,0xff,0xe7,0xc3,0x81,0x00,0x81,0xc3,0xe7,0xff, 0xaa,0x55,0x18,0xff,0xf0,0x0f,0x00,0xff,0xf8,0xf1,0xe3,0xc7,0x8f,0x1f,0x3f,0x7f, 0x7f,0x3f,0x1f,0x8f,0xc7,0xe3,0xf1,0xf8,0xff,0x00,0x00,0xff,0xff,0x0f,0xf0,0xff, 0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff, 0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0x7f,0xbf,0xdf,0xef,0xf7,0xfb,0xfd,0xfe, 0xfe,0xfc,0xf8,0xf0,0xe0,0xc0,0x80,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x80,0xc0,0xe0,0xf0,0xf8,0xfc,0xfe, 0x00,0xff,0x00,0xff,0x00,0xff,0x00,0xff }; ucha
