Description: 单片机演奏一个音符，是通过引脚，周期性的输出一个特定频率的方波。这就需要单片机?
下面是个网上广泛流传的单片机音乐演奏程序，很多人都关心如何修改乐曲的内容，但是不知如何入手。做而论道对这个软件，做了一些说明，希望对大家有所帮助，以后大家自己就能够编写进去新的乐曲。
在这个程序中，包括了两个数据表，其中存放了事先算好的、各种音符频率所对应的、半周期的定时时间初始值。有了这些数据，单片机就可以演奏从低音、中音、高音和超高音，四个八度共28个音符。-The microcontroller played a note by pin, periodic output of a specific frequency square wave. This requires microcontroller? Following widespread online MCU music playing program, many people are concerned about how to modify the content of the song, but I do not know how to start. Do pontificating on this software, some notes, and we want to help, that we will be able to write into the new music. In this procedure, including the two data tables which is stored in advance is quite good, and various note frequencies corresponding to the timing of the half cycle time initial value. With these data, the microcontroller can be played from the bass, midrange, treble, and ultra sound, four octaves of 28 notes. Platform: |

与其控制的音符构成音高，决定发音频率，音高的后面是音长，可以用整数或小数输入以控制时间，但中间必须用空各隔开。
乐谱文件的得最前面是一个整数，白噢是音长基数，一般为300 600 900 1200ms；乐谱文件最后世结束符 “##” ，以表示乐谱文件的结束。
程序对读入的乐谱进行翻译， 确定每个乐音的频率和声长， 每个音的音长=音长基数*节拍数，其中技术是乐谱文件的第一个字符。
由于DOS下用来发声的sound函数只能以频率作为参数，所以要完成音符到频率的翻译，没个音的音频可用以模拟频率值输入。-* said top note
H says soprano
M says alto
L said bass
Instead of controlling the notes form pitch, decided to sound frequency, pitch is behind the duration, can use the integer or decimal input to control the time, but must be separated with empty each in the middle.
Music files to the front is an integer, white base, oh is duration generally is 300 600 300 1200 ms Music file finally the terminator \"##\", to indicate the end of the music files.
For translation program to read music, make sure each tone frequency harmonic long, the length of each sound = length base* ticks, the first character technology is music files.
Due to DOS can only be used for voice sound function with frequency as parameter, so to complete the notes to the frequency of the translation, not a sound audio input can be used to simulate the frequency value. Platform: |

Description: 简易电子琴演奏器的VHDL实现
本实验实现了简易的电子琴演奏，包括自动和手动演奏。
输入为BTN0~BTN6，代表1~7共7个音符。音高可切换低中高音，用两个拨码开关控制：“00”为低音，“10”或“01”为中音，“11”为高音。一个拨码开关切换收动/自动。一个开关控制存储（播放存储）/不存储。一个按键clr复位。
输出为8*8点阵、两个数码管（显示音高和字符）、蜂鸣器。
具体功能：
当切换至手动模式时，根据手动按键播放音乐并显示。此时若存储开关置1，当前播放音符被存储，采样频率10HZ。
当切换置自动模式时，播放系统自身存储的音乐。此时若存储开关置1，播放的是之前手动播放时存储的音乐。若再切换回手动模式，则音乐可以接上回位置继续往下存储。
当clr置1时，系统回到手动播放的等待状态，并将已存储的音乐清除。
