初级组三等奖队名缤纷成员钟恒

电子琴队名：缤 成员现通过按键控制，发出、i……等二十一个音符。该电子琴亦能够自动同时在eeprom里面，掉电不丢失。一、方案的设计和论证1、电源控制控制模（1（22、主控模51系列单片机、AVRARM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I/O口的占用量。1602的成本中等，是值得考虑的选择。（2）128644X16个汉字，甚至可以显示图AVR单片机自带的3、音量调节模（1（2另外，在如何显示音量大小的问题上，我们采用的是以数字TA6777来驱4、功放模（1：方（2采用TDA2822放大音乐信号但是TDA2822在单电源供电下，（15、键盘输入模（1（N×M口数目是N+M,N×M（2I/O资源，故采用之。基于AtmelMega16L电子琴系统的硬件总体结构图如图1所示，主要包括处理1、处理器CMOS2PB0～PB7用于连接键盘输入（INT2用于键盘的中断输入；PD0用于连接单键开关等的操作，PC3～PC774HC595，实现串行数据转并行数据。CTC信号的模式传给功放电路，实现放音乐的功能。按下来就可以从菜单里选择刚才录入的音乐。2、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，Q29012导通，VCCP_OUT一Q19013S2松开了，Q2也依然导通，电路依然S2P_IN为低电平，这是单片机可以延时一段时P_OUT置为低电平，Q1截止，Q2也同时截止，电路断开。是一块TP7666，该在老式收音机上非常常见，现在已经很难买到。该具有双路5点电平显示，而且电路原件很少。4、6×6由高电平变为低电平，由此产生一个中断；MCUK30时，置POT1=HLLLLPORT1、PORT3～6HLLL，按键S30就被唯一确定了。11IO口，这里最多只需要5IO口，这样连接一片1602只需要8IO口，节省了3IO口。具体的硬5所示。这里的功放模块采用了传统的LM386，采用该是因为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时使用的原件极少。具体的单路连接如下图6所示。音音
