【基于单片机音乐流水灯的控制系统设计与实现12000字（论文）】

[20]其图如5-2所示：图5-1AT89C51属性编辑对话框图5-2流水灯硬件仿真结果结论毕业设计是基于单片机的音乐流水灯控制系统设计，设计拟由三个按钮控制音乐的上下歌曲切换和暂停播放。在切换五首歌曲的同时，8个LED灯随蜂鸣器中的曲调闪烁和律动。实现这些效果需要单片机对电路系统的控制配合来达到。相应的要对电路进行模块化设计，程序再控制电器元件互相配合，从而完成设计要求。比如流水灯的设计，把固定的闪烁模式在本设计中通过音乐节拍改为随音乐而律动的程序。而本系统设计中的程序编译设计占有很大的比重，特别是音乐节拍和流水灯闪烁的结合与音乐流水灯控制系统操控的显示。结合所学知识完成本设计也极具挑战性，但完成毕业设计也入让我对单片机有了更深的了解，各个方面都让我深受洗礼，这对我以后的工作、生活有很大的助臂。参考文献南京工业职业技术学院.一种蓝牙音乐双心形流水灯[P].CN：206771051，2017.12.19.南京信息工程大学.一种用于儿童车的音乐流水灯[P].CN：202703765，2013.01.30.姜红星教传艳施利.浅析单片机的LED流水灯控制过程[J].沈阳工学院机械与运载学院.2017,(第06期).MeehanJoanneMuirLindsey.SCMinMerseysideSMEs:Benefitsandbarriers[J].TOMJournal,2008.刘利民.MCS-51系列单片机系统设计[M].北京：北京航空航天大学出版社，2008.5.刘玲,刘新,张鹏鸣.基于FPGA的数码管音乐流水灯设计[J].沈阳师范大学学报(自然科学版),2019.陶小苗,王紫婷.基于FPGA的音乐流水灯控制系统的设计[J].电子科技,2010,(第11期).周明周亮.AT89C51单片机在霓虹灯控制中的应用[J].吉林师范大学计算机学院，四平.2007,(第05期).邓和莲.可编程音乐彩灯系统设计[J].娄底职业技术学院,2007.杜毅.基于单片机的可调速音乐流水灯[J].企业技术开发(上半月),2011,(第5期).梁平元.基于音乐节奏识别的智能LED流水灯以及其控制方法[P].CN：106332378，2017.01.11.郑超.基于Proteus的单片机教学实验仿真平台[D].华南理工大学,2017.祝清法.自制音乐流水灯[N].电子报,2010,(第011版).许艺珍.关于单片机LED点阵流水灯的制作[J].西南石油大学2018,(第06期).雷友建.音乐流水灯的单片机控制研究[J].科教导刊(电子版)(中旬),2013,(第2期).HengYu,PengZhou,andShi-longZhang.CompensationLEDLight-ControlSystemDesignandImplementationofIntelligentLightCompensationLEDLight-ControlSystem[J].Wuhan430070,China.蒙启熟.基于51单片机的音乐喷泉设计[J].广西城市职业大学.2019,(第12期).任杰.DIY简易声控流水彩灯[J].无线电杂志,2008,(第7期).倪云峰.单片机原理与应用[M].西安：西安电子科技大学出版社，2009.6.倪云峰.单片机原理与应用[M].西安：西安电子科技大学出版社，2009.6.附录电路原理图：音乐程序：#include"main.h"staticuint8_t*play_music_index=NULL;//共五首歌，省略了后四首//挥着翅膀的女孩uint8_tcodeMusic_Girl[]={0x17,0x02,0x17,0x03,0x18,0x03,0x19,0x02,0x15,0x03,0x16,0x03,0x17,0x03,0x17,0x03,0x17,0x03,0x18,0x03,0x19,0x02,0x16,0x03,0x17,0x03,0x18,0x02,0x18,0x03,0x17,0x03,0x15,0x02,0x18,0x03,0x17,0x03,0x18,0x02,0x10,0x03,0x15,0x03,0x16,0x02,0x15,0x03,0x16,0x03,0x17,0x02,0x17,0x03,0x18,0x03,0x19,0x02,0x1A,0x03,0x1B,0x03,0x1F,0x03,0x1F,0x03,0x17,0x03,0x18,0x03,0x19,0x02,0x16,0x03,0x17,0x03,0x18,0x03,0x17,0x03,0x18,0x03,0x1F,0x03,0x1F,0x02,0x16,0x03,0x17,0x03,0x18,0x03,0x17,0x03,0x18,0x03,0x20,0x03,0x20,0x02,0x1F,0x03,0x1B,0x03,0x1F,0x66,0x20,0x03,0x21,0x03,0x20,0x03,0x1F,0x03,0x1B,0x03,0x1F,0x66,0x1F,0x03,0x1B,0x03,0x19,0x03,0x19,0x03,0x15,0x03,0x1A,0x66,0x1A,0x03,0x19,0x03,0x15,0x03,0x15,0x03,0x17,0x03,0x16,0x66,0x17,0x04,0x18,0x04,0x18,0x03,0x19,0x03,0x1F,0x03,0x1B,0x03,0x1F,0x66,0x20,0x03,0x21,0x03,0x20,0x03,0x1F,0x03,0x1B,0x03,0x1F,0x66,0x1F,0x03,0x1B,0x03,0x19,0x03,0x19,0x03,0x15,0x03,0x1A,0x66,0x1A,0x03,0x19,0x03,0x19,0x03,0x1F,0x03,0x1B,0x03,0x1F,0x00,0x1A,0x03,0x1A,0x03,0x1A,0x03,0x1B,0x03,0x1B,0x03,0x1A,0x03,0x19,0x03,0x19,0x02,0x17,0x03,0x15,0x17,0x15,0x03,0x16,0x03,0x17,0x03,0x18,0x03,0x17,0x04,0x18,0x0E,0x18,0x03,0x17,0x04,0x18,0x0E,0x18,0x66,0x17,0x03,0x18,0x03,0x17,0x03,0x18,0x03,0x20,0x03,0x20,0x02,0x1F,0x03,0x1B,0x03,0x1F,0x66,0x20,0x03,0x21,0x03,0x20,0x03,0x1F,0x03,0x1B,0x03,0x1F,0x66,0x1F,0x04,0x1B,0x0E,0x1B,0x03,0x19,0x03,0x19,0x03,0x15,0x03,0x1A,0x66,0x1A,0x03,0x19,0x03,0x15,0x03,0x15,0x03,0x17,0x03,0x16,0x66,0x17,0x04,0x18,0x04,0x18,0x03,0x19,0x03,0x1F,0x03,0x1B,0x03,0x1F,0x66,0x20,0x03,0x21,0x03,0x20,0x03,0x1F,0x03,0x1B,0x03,0x1F,0x66,0x1F,0x03,0x1B,0x03,0x19,0x03,0x19,0x03,0x15,0x03,0x1A,0x66,0x1A,0x03,0x19,0x03,0x19,0x03,0x1F,0x03,0x1B,0x03,0x1F,0x00,0x18,0x02,0x18,0x03,0x1A,0x03,0x19,0x0D,0x15,0x03,0x15,0x02,0x18,0x66,0x16,0x02,0x17,0x02,0x15,0x00,0x00,0x00};//同一首歌uint8_tcodeMusic_Same[]=//两只蝴蝶uint8_tcodeMusic_Two[]=//生日快乐unsignedcharcodeMusic_happy_birthday[]=//大海unsignedcharcodeMusic_DaHai[]=boolis_change_play=false;staticcodeuint8_t*music_list[]={Music_Girl,Music_Same,Music_Two,Music_happy_birthday,Music_DaHai};staticuint8_tmusic_list_index=0;#defineMAX_MUSIC_INDEX(4)boolis_pasue_play=false;sbitP37=P3^7;/**/staticvoiddisplay(void){lcd12864_clear_display(0);if(music_list_index==0){lcd12864_show_line_chinese(0,0,(uint8_t*)"挥着翅膀的女孩");}elseif(music_list_index==1){lcd12864_show_line_chinese(0,0,(uint8_t*)"同一首歌");}elseif(music_list_index==2){lcd12864_show_line_chinese(0,0,(uint8_t*)"两只蝴蝶");}elseif(music_list_index==3){lcd12864_show_line_chinese(0,0,(uint8_t*)"生日快乐");}elseif(music_list_index==4){lcd12864_show_line_chinese(0,0,(uint8_t*)"大海");}}/**/staticvoidkey_poll(void){if(is_key_down(0)){is_change_play=true;EA=0;++music_list_index;if(music_list_index>MAX_MUSIC_INDEX){music_list_index=0;}play_music_index=music_list[music_list_index];display();}if(is_key_down(1)){is_change_play=true;EA=0;if(music_list_index>0){music_list_index--;}else{music_list_index=MAX_MUSIC_INDEX;}play_music_index=music_list[music_list_index];display();}if(is_key_down(2)){is_change_play=true;EA=0;is_pasue_play=!is_pasue_play;}}/**/staticvoidplay_music_poll(void){if(is_pasue_play){P37=1;return;}beep_play_music(play_music_index);}/**/voidbeep_play_music_callback(void){key_poll();}/**///程序入口函数mainvoidmain(void){P1=0xfe;lcd12864_init();beep_sound_init();play_music_index=music_list[1];display();EA=1;while(1){key_poll();play_music_poll();}}蜂鸣器程序：#include"main.h"#ifdef__BEEP_DEV_DRIVER__//宏定义sbitBEEP_IO_PIN=P3^7;///<定义蜂鸣器输出管脚#defineIS_BEEP_CALLB
