一、 使用键盘显示接口芯片8279接收按键键值，并在七段数码管上显示出来，通过判断键值进入相应音乐播放处理程序。在音乐播放程序中，使用定时器/计数器8253的计数器2，使其工作在方式¬ ¬ 3―方波发生器，通过查表依次取出乐曲频率值送入计数器作为计数初值，经out2输出方波，驱动扬声器发出不同频率的声音，在每个音阶之间加入相应的延迟时间，即实现了音乐的播放。-First, the use of a keyboard display interface chip receive keys keys 8279, and Seven-Segment LED display, through to determine the corresponding music player keys to enter the treatment program. Procedures in the music player, use the timer/counter 2 counter 8253 to work in the way ? ? 3- square-wave generator, followed by out music through the look-up table values into the counter as a frequency count of the initial value, the output side out2 waves, driven loudspeakers of different frequency sound, in between each scale by adding the appropriate delay time, namely, the realization of the music player.

运行可执行程序testword.exe，出现菜单主界面，按回车键出现由26个字母组成的乱序行，这时其中任一字母落下，在键盘上敲入该字母，如果输入正确，字母消失；按ESC键返回主界面；按空格见暂停；按‘E’退出。 -running executable testword.exe, there main menu interface, press the Enter key emerging from the 26 letters of the alphabet disorder OK, then any one of the letters fall into nice in the letter, if the importation is correct, the letters disappeared; According to the ESC key to return to the main interface; See box suspended by ; according to "E" withdrawal.

这个程序是用Intel8086平台运行的一个汇编语言程序，其中包含两首歌，可通过控制来实现音乐播放的功能，同时，也以实现按键控制8086发出声音的功能。
