电子琴设计报告VIP

电子琴设计报告摘要功能：本作品是基于单片机控制系统的简易电子琴，有各种友好的菜单界面和显示界面，可实现通过按键控制，发出1、2、3、4、5、6、7、i……等二十一个音符。该电子琴亦能够自动演奏三首乐曲，且其演奏方式（点播、顺序播放和随机播放）可以通过按键选择（其中点播模式还可以点播之前的录音，可以播放掉电之前保存的录音）。操作者还可以在电子琴演奏时对电子琴进行音调（按键控制）、音量（电位器）的调节，并能以发光二极管显示播放音量的大小。同时在设置模式下能调节音阶和拍长，音阶和拍长在掉电后仍然保存。另外，它可以对手动编奏的乐曲进行录音，在按下放音键时能演奏出来，同时贮存在eeprom里面，掉电不丢失。还有一键关机功能，一键按下关闭整个电路板的电源。方案的设计和论证电源控制控制模块方案（1）：采用继电器来控制电源的关断，其优点是电路设计比较简单，但是由于继电器的体积偏大，如果以后要做出易于携带的产品的话，不是很方便；方案（2）：运用晶体管的开关功能设计电源开关控制电路，通过向单片机输入外部中断来使得单片机自动控制电源的关断。主控模块这模块主要实现的功能有：=1\*GB3①接收由键盘输入的信号并输出相应的操作信号；=2\*GB3②控制菜单操作显示器基于以上标示，可考虑采用51系列单片机、AVR单片机，或者ARM等都可以实现，但是从性价比考虑，AVR系列优势比较明显，因此选用之作为主控芯片。至于菜单显示部分可以采用以下两种方案：（1）1602液晶：它能显示16X2个数字或英文字符，信息量较大，用串行通讯可减少I/O口的占用量。1602的成本中等，是值得考虑的选择。（2）12864是带中文字库的液晶显示屏，可以显示4X16个汉字，甚至可以显示图案，显示功能较为强大。使用12864可以提供大量信息，但是其价格比较1602液晶要贵几倍。考虑到成本因素，决定采用1602液晶来实现该显示功能。掉电保护电路：（1）使用外部存储器不过得加入外部电路，既加大成本又加大功耗。（2）使用AVR单片机自带的EEPROM不用增加器件，操作简单。综上所述，我们采用第（2）种掉电保护方案。音量调节模块方案（1）：采用数字电位器对音量进行调节，这样做的好处是便于数字控制，可以选择的音量大小不多。方案（2）：采用可变电阻进行音量调节，这样可实现音量连续可调。另外，在如何显示音量大小的问题上，我们采用的是以数字芯片TA6777来驱动发光二极管，当音量比较大时，发光二极管亮的个数比较多。功放模块方案（1）：采用LM386芯片对对输出的音乐信号进行放大，其优点是电路简单，稳定性强；方案（2）：采用TDA2822芯片放大音乐信号，但是TDA2822在单电源供电下，工作不是很稳定。考虑到稳定性因素，选用方案（1）。键盘输入模块方案（1）：采用矩阵键盘（N×M），每个按键占据行列的一个交点，需要的I/O口数目是N+M,容许的最大键数是N×M。方案（2）：新型键盘，用N个I/O口以及一个中断口，可以实现N×N个按键，比较节省I/O资源，故采用之。系统框图基于AtmelMega16L电子琴系统的硬件总体结构图如图1所示，主要包括中央处理器MCU、单键开关机电路，1602显示模块、功放模块、键盘模块、电平灯频谱显示模块等。各模块的设计与论证中央处理器MCU中央处理器选用的是ATMega16l，ATmega16是基于增强的AVRRISC结构的低功耗8位CMOS微控制器。具体的电路连接图如图2所示。PB0～PB7用于连接键盘输入（INT2用于键盘的中断输入）；PD0用于连接单键开关电路的续电；PD2（INT0）用于连接单键开关电路按键的检测；PD5用于音律PWM的输出；PC0～PC7用于连接LCD1602显示输出，其中PC0～PC2用于控制1602的选通、读写控制等的操作，PC3～PC7连接74HC595，实现串行数据转并行数据。单片机输出频率CTC不同的信号来产生各种音符，将歌曲各个音符的转化成相应的数字信号，存放在单片机程序寄存器中，当播放音乐时，程序从该寄存器里读取数据，然后以CTC信号的模式传给功放电路，实现放音乐的功能。当要向单片机录入音乐时，通过键盘上的按键，输入不同的音符，接下来单片机可以记录下音符以及其持续的时间，然后存入程序寄存器中，当录音结束，按下“录入确认键”，按下来就可以从菜单里选择播放刚才录入的音乐。单键开关机模块该电路的工作原理是：接通K1（总电源开关，外电源接到P0）后，按动轻触开关S2，三极管Q29012导通，VCC输出高电平，单片机接通电源工作后，第一时间给P_OUT一个高电平，三极管Q19013导通，这样，即使按键S2松开了，Q2也依然导通，电路依然接通。当按键S2再次按下时，单片机检测到P_IN为低电平，这是单片机可以延时一段时间后，将P_OUT置为低电平，Q1截止，Q2也同时截止，电路断开。3、电平灯频谱显示模块为了显示的效果更炫，本硬件电路特意增加了一个电平灯频谱显示模块，该模块采用的是一块TP7666芯片，该芯片在老式收音机上非常常见，现在已经很难买到。该芯片具有双路5点电平显示，而且外围电路原件很少。4、6×6键盘模块该电路的工作原理是：待机时，PORT1～PORT6输出高电平；当某个键按下时，PORT7由高电平变为低电平，由此产生一个中断；MCU启动按键扫描，如按下的是K30时，置PORT1=H，扫描PORT2～6的输入结果为LLLL，没有扫描到所需的结果；继续置PORT2=H，扫描PORT1、PORT3～6的输入结果为HLLL，按键S30就被唯一确定了。5、LCD1602液晶显示模块该模块的连接比较简单，但是若直接使用并行数据传送的话要用到11个IO口，这里为了节省IO口资源，使用也一片74HC595串行数据转并行数据芯片，该芯片与单片机连接最多只需要5个IO口，这样连接一片1602只需要8个IO口，节省了3个IO口。具体的硬件连接图如下图5所示。电位器RW1可用于调节背光的亮度，RW2可用于调节液晶的对比度。6、小功率功放模块这里的功放模块采用了传统的LM386芯片，采用该芯片是因为LM386具有自身功耗低,电压增益可调整,电源电压范围大,外接元件少和总谐波失真小等优点,尤其是在增益为20DB时使用的外围原件极少。具体的单路连接如下图6所示。软件程序流程图测量与分析1（do）2(re)3(mi)4(fa)5(sol)6(la)7(si)降C131Hz147Hz165Hz174.5Hz196Hz220Hz音符音符音阶中央C261.5Hz293.5Hz329.5Hz349Hz392Hz440Hz494Hz升C523Hz587Hz659Hz698Hz784Hz880Hz988Hz输出音调对应的频率表按C调来说1=261.5HZ2=293.5HZ3=329.5HZ4=349HZ5=392HZ6=440HZ7=494HZ低7个音调后1=131Hz2=147Hz3=165Hz4=174.5Hz5=196Hz6=220Hz7=247Hz高7个音调后1=523Hz2=587Hz3=659Hz4=698Hz5=784Hz6=880Hz7=988Hz总结 经过一翻辛苦努力，终于搞定了电子琴了。这个过程中团队合作让我们收获很多。三个同学一起做，不可能每个同学对每项内容都了解得很透彻，需要知识互补。另外，遇到困难的时候不能指望让一个同学独自解决，团队合作不崇尚单打独斗。源程序主文件go.c：//主文件，包含主函数#include<iom16v.h>#include<macros.h>#include<eeprom.h>#defineucharunsignedchar#defineuintunsignedint#definevucharvolatileunsignedchar#definevuintvolatileunsignedint#definerecord_max160//变量定义vucharkey_int=0,mode_fr=0,counter_en_fr=0,pop_en_fr=0;vucharrow=0,scrollbar=1,volume,temp,delayMs,tonality,tone;vucharinttemp;ucharmusicLength,recordLength;uintbell_standard_time;vuintcounter_ms=0;vucharcounter_record;vucharsong_4[record_max][2];//包含头文件//子函数清单#include"function_list.h"//数据#include"data.h"//延时#include"delay.h"//键盘中断#include"int2.h"//液晶#include"ts1620.h"//发声部分#include"bell.h"//功能函数1#include"fun.h"//功能函数2#include"fun_need_check.h"voidmain(){
