数码管单片机c语言程序设计 1、一个管亮《静态》 #includereg52.h #define uint unsigned int #define uchar unsigned char sbit Wela=P2^1; sbit Dula=P2^2; void main(void) { Wela=1; P0=0xfe; Wela=0; Dula=1; P0=0x7d; Dula=0; while(1); } 2、一个管亮《动态》 #includereg52.h #define uint unsigned int #define uchar unsigned char void Delay_Us(uchar t); void Delay_Ms(uint t); sbit Wela=P2^1; sbit Dula=P2^2; uchar num; uchar code table2[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f}; uchar code table1[]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f}; void main(void) { while(1) { for(num=0;num10;num++) { Dula=1; P0=table2[num]; Dula=0; Wela=1; P0=0xfe; Wela=0; Delay_Ms(500); } } } void Delay_Us(uchar t) { while(--t); } void Delay_Ms(uint t) { while(t--){ Delay_Us(245); Delay_Us(245); } } 3、全部管闪 #includereg52.h #define uint unsigned int #define uchar unsigned char void Delay_Us(uchar t); void Delay_Ms(uint t); sbit Wela=P2^1; sbit Dula=P2^2; uchar num; uchar code table[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71}; void main(void) { Wela=1; P0=0x00; Wela=0; while(1) { for(num=0;num16;num++) { Dula=1; P0=table[num]; Dula=0; Delay_Ms(100); } } } void Delay_Us(uchar t) { while(--t); } void Delay_Ms(uint t) { while(t--){ Delay_Us(245); Delay_Us(245); } } 4、流水数字 #includereg52.h #define uint unsigned int #define uchar unsigned char void Delay_Us(uchar t); void Delay_Ms(uint t); sbit Wela=P2^1; sbit Dula=P2^2; uchar num; uchar code table2[]={0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f}; uchar code table1[]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f}; void main(void) { while(1) { for(num=0;num8;num++) { Dula=1; P0=table2[num]; Dula=0; Wela=1; P0=
