D15.3。

移3）第三种花式灯显示方式为：从D1移向D2，尔后D1熄灭，再从D2移向D3，尔后D2熄灭，以此往来循环。与第一种方式的不同样之处为：当D1移向D2时，D1不熄灭，再从D2移向D3时，D2也不熄灭，以此类推。六、实验程序#include<reg52.h>#defineucharunsignedchar#defineuintunsignedintsbitduan=P2^6;sbitkey1=P3^2;//按key1可切换花式sbitkey2=P3^3;//按key2可切换歌曲sbitfm=P0^7;//蜂鸣器连续的IO口sbitP34=P3^4;//矩阵键盘的一列ucharcodehuayang1[]={0x7f,0xbf,0xdf,0xef,0xf7,0xfb,0xfd,0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf};//花式1ucharcodehuayang2[]={0x7f,0xfe,0xbf,0xfd,0xdf,0xfb,0xef,0xf7,0xef,0xfb,0xdf,0xfd,0xbf,0xfe};//花式2ucharcodehuayang3[]={0x7f,0x3f,0x1f,0x0f,0x07,0x03,0x01,0x0,0x80,0xc0,0xe0,0xf0,0xf8,0xfc,0xfe,0xff};charcodehuayang4[]={0x55,0xaa,0xcc,0x33,0x99,0x66,0x0f,0xf0};ucharcount1;//花式标志ucharcount2;//歌曲标志uchartimeh,timel,i;//简谱//编程规则字节高位是简谱,低位是连续时间,//代表多少个十六分音符//1-7代表中央C调,8-E代表高八度,0代表逗留//最后的0是结束标志ucharcodeqnzl[]={//千年之恋0x12,0x22,0x34,0x84,0x74,0x54,0x38,0x42,0x32,0x22,0x42,0x34,0x84,0x72,0x82,0x94,0xA8,0x08,//前奏0x32,0x31,0x21,0x32,0x52,0x32,0x31,0x21,0x32,0x62,//竹林的灯火到过的沙漠0x32,0x31,0x21,0x32,0x82,0x71,0x81,0x71,0x51,0x32,0x22,//七色的国家不断俊逸风中0x32,0x31,0x21,0x32,0x52,0x32,0x31,0x21,0x32,0x62,//有一种奇特灰色的旋涡0x32,0x31,0x21,0x32,0x83,0x82,0x71,0x72,0x02,//将我卷入了迷雾中0x63,0xA1,0xA2,0x62,0x92,0x82,0x52,//看不清的双手0x31,0x51,0x63,0x51,0x63,0x51,0x63,0x51,0x62,0x82,0x7C,0x02,//一朵花传来谁经过的温柔0x61,0x71,0x82,0x71,0x62,0xA2,0x71,0x76,//穿越千年的伤痛0x61,0x71,0x82,0x71,0x62,0x52,0x31,0x36,//只为求一个结果0x61,0x71,0x82,0x71,0x62,0xA3,0x73,0x62,0x53,//你留下的轮廓指引我0x42,0x63,0x83,0x83,0x91,0x91,//黑夜中不孤单0x61,0x71,0x82,0x71,0x62,0x0A2,0x71,0x76,//穿越千年的忧虑0x61,0x71,0x82,0x71,0x62,0x52,0x31,0x36,//是你在尽优等我0x61,0x71,0x82,0x71,0x62,0xA3,0x73,0x62,0x53,//最美丽的动人会值得0x42,0x82,0x88,0x02,0x74,0x93,0x89,0xff//结束标志//用一世等待};ucharcodejmszl[]={//孤单沙洲冷0x12,0x12,0x22,0x32,0x31,0x22,0x21,0x22,//自你走后心憔倅0x21,0x31,0x51,0x52,0x31,0x52,0x61,0x15,0x14,//白色油桐风中纷飞0x51,0x52,0x31,0x52,0x62,0x13,0x11,0x13,0x32,0x28,0x08,0x28,//落花似人有情这个季节0x31,0x32,0x31,0x32,0x11,0x21,0x51,0x52,0x51,0x52,//河畔的风?嚣张拼命地吹0x51,0x51,0x31,0x32,0x31,0x32,0x81,0x72,0x63,//不断拨弄离人的眼泪0x62,0x71,0x81,0x72,0x61,0x61,0x52,0x31,0x21,0x32,0x51,0x54,//那样浓烈的爱再也无法给0x22,0x12,0x11,0x12,0x11,0x12,0x12,0x14,0x26,0x32,0x26,//伤感一夜一夜0x32,0x61,0x51,0x51,0x31,0x31,0x21,0x31,0x51,0x61,0x51,0x31,0x51,//当记忆的线围绕过往支离破碎0x02,0x32,0x81,0x81,0x81,0x81,0x62,0x52,0x34,//是慌乱据有了心扉0x31,0x81,0x81,0x81,0x61,0x91,0x82,//有花儿伴着蝴蝶0x51,0x51,0x51,0x51,0x31,0x61,0x53,//孤雁能够双飞0x21,0x11,0x21,0x11,0x22,0x11,0x21,0x26,//更深夜静独彷徨0x32,0x61,0x51,0x51,0x31,0x31,0x21,0x31,0x51,0x61,0x51,0x31,0x51,0x52,//当幸福恋人寄来红色分享欢乐0x31,0x31,0x81,0x81,0x81,0x61,0x91,0x81,0x61,0x31,0x56,//闭上双眼伤心头也不敢回0x32,0x32,0x81,0x81,0x81,0x81,0x91,0x81,0x61,0x81,0x61,0x51,0x31,0x51,0x34,//依旧捡尽寒枝不肯安歇微带着后悔0x21,0x31,0x51,0x31,0x21,0x11,0x61,0x21,0x16,//孤单沙洲我该思念谁0xff};//
