心形花样LED 流水灯(带程序)使用89C52做的,原理图如下:总共有32个LED灯,4个I/O全部用上了。我在这里不加有LED保护电阻,,C1,C2用30PF。程序是用C语言写的;如下:#include<>#include<>#define uintunsignedint#define ucharunsignedcharucharcodetable[]={0xfe,0xfc,0xf8,0xf0,0xe0,0xc0,0x80,0x00};//逐个点亮0~7ucharcodetable1[]={0x7f,0x3f,0x1f,0x0f,0x07,0x03,0x01,0x00};//逐个点亮7~0ucharcodetable2[]={0x01,0x03,0x07,0x0f,0x1f,0x3f,0x7f,0xff};//逐个灭0~7ucharcodetable3[]={0x80,0xc0,0xe0,0xf0,0xf8,0xfc,0xfe,0xff};//逐个灭7~0/***********************************************************/voiddelay(uintt); //延时voidzg(uintt,uchara);//两边逐个亮voidqs(uintt,uchara);//全部闪烁voidzgxh(uintt,uchara);//逆时针逐个点亮//voidzgxh1(uintt,uchara);//顺时针逐个点亮voiddjs(uintt,uchara);//对角闪voidlbzgm(uintt,uchara);//两边逐个灭//voidsszgm(uintt,uchara);//顺时针逐个灭voidnszgm(uintt,uchara);//逆时针逐个灭voidsztl(uintt,uchara);//顺时逐个同步亮voidnztl(uintt,uchara);//逆时逐个同步亮voidsztm(uintt,uchara);//顺时逐个同步灭voidnztm(uintt,uchara);//逆时逐个同步灭voidhwzjl(uintt,uchara);//横往中间亮voidhwzjm(uintt,uchara);//横往中间灭//voidswzjl(uintt,uchara);//竖往中间亮//voidswzjm(uintt,uchara);//竖往中间灭voidnzdl(uintt,uchara);//逆时逐段亮voidnzdgl(uintt,uchara);//逆时逐段一个点亮voidjgs(uintt,uchara);//间隔闪/**********************************************************/voidzg(uintt,uchara)//两边逐个亮{ uchari,j;for(j=0;j<a;j++) { P0=P1=P2=P3=0xff; P0=0x7f;delay(t); for(i=0;i<7;i++) { P0=table1[i+1]; P2=table1[i]; delay(t); } P2=0x00;P1=0xfe; delay(t); for(i=0;i<7;i++) { P1=table[i+1]; P3=table1[i]; delay(t); } P3=0x00;delay(t); }}voidqs(uintt,uchara) //全部闪烁{ ucharj; for(j=0;j<a;j++) { P0=P1=P2=P3=0xff; delay(t); P0=P1=P2=P3=0x00; delay(t); } }voidzgxh(uintt,uchara)//逆时针逐个点亮{ uchari,j; for(j=0;j<a;j++) { P0=P1=P2=P3=0xff; for(i=0;i<8;i++) { P0=table1[i]; delay(t); } for(i=0;i<8;i++) { P1=table[i]; delay(t); } for(i=0;i<8;i++) { P3=table[i]; delay(t); } for(i=0;i<8;i++) { P2=table[i]; delay(t); } }}voidnszgm(uintt,uchara)//逆时针逐个灭{ uchari,j; for(j=0;j<a;j++) { P0=P1=P2=P3=0x00; for(i=0;i<8;i++) { P0=table3[i];delay(t); } for(i=0;i<8;i++) { P1=table2
