关于心形小灯的51程序设计

ti

本设计包含五种闪烁模式，分别为：全亮、闪烁、滚动、1/3补全、1/2补全和呼吸，通过两个外部中断控制不同模式的切换。#include#include#define uint unsigned int#define uchar unsigned char***it key0 = P3^2;***it key1 = P3^3;***it mouth_up = P1^6;***it mouth_down = P1^7;uint mode = 0;uchar stars[24][2] = {{0xfe,0x01},{0xfe,0x02},{0xfe,0x04},{0xfe,0x08},{0xfe,0x10},{0xfe,0x20},{0xfe,0x40},{0xfe,0x80},{0xfd,0x01},{0xfd,0x02},{0xfd,0x04},{0xfd,0x08},{0xfd,0x10},{0xfd,0x20},{0xfd,0x40},{0xfd,0x80},{0xfb,0x01},{0xfb,0x02},{0xfb,0x04},{0xfb,0x08},{0xfb,0x10},{0xfb,0x20},{0xfb,0x40},{0xfb,0x80}};uchar vm[8] = {0x01,0x03,0x07,0x0f,0x1f,0x3f,0x7f,0xff};//uchar v[8]= {0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80};//p2->v//uchar h[3]= {0xfe,0xfd,0xfb};//p0->hvoid delay(uint x,uint y)//单步执行7*E-4{ int i,j; for(i = 0;i0;x--) for(y=20;y>0;y--);}/********************************//**************Define a point***************/void dpoint(uchar *array){ P1 = array[0]; P2 = array[1];}/**************Mod***************/void mode2(){ int time = 10; while(time--) { int i; for(i=0;i<24;i++){ if(i%2 == 0) dpoint(stars[i]); delay(5,14); } } time = 10; while(time--) { int i; for(i=0;i<24;i++){ if(i%2 != 0) dpoint(stars[i]); delay(5,14); } }}
