实现高级电子琴的程序，并实现若干扩展功能。 基本功能：用8257键盘输入对应的七个音阶，通过实验箱的喇叭发出声音，并通过七段数码管显示输入音阶； 扩展功能：1、录音：记录所弹奏曲目 2、放录音：任意时刻重放最新记录曲目 3、在程序中可预设一曲目，按一键实现播放该曲目。 4、在播放录制曲目或预设曲目时，按8279键盘上任意键可以暂停播放，再按一次从暂停处继续播放。 5、程序运行时有友好的用户介面 -Realize high-level organ of the process and realize a number of extensions. Basic functions: keyboard 8257 corresponds with the seven scale, through experimental sound speaker boxes, and through Seven-Segment LED display input scale the expansion of functions: one, sound recording: Record the playing pieces 2, released recordings: any time replay music 3-to-date records, in the proceedings may be the default one track, according to realize one key to play the tracks. 4, recording tracks in the player or the default program, press any key on the keyboard 8279 can pause playback, press once again to continue from the suspended players. 5, is running friendly user interface
