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.

本程序由国外的Vulture大哥编写,并公布了源码,这个是他95年的一个作品,可以说是在当时是非常成功的!
这个程序是巧妙的利用了坐标的不断变化,从而实现了由星星构成的箱子3D转动!
为了尊重版权,本人未对源码注释进行翻译,这样做也可以让国内的汇编爱好者自己琢磨国外的汇编编程的思维-This program prepared by the foreign Vulture brother, and announced the source code, this is his 95 years, a work can be said that at that time was very successful! The program is clever use of changing coordinates in order to achieve a box formed by the stars, 3D rotation! In order to respect copyright, I did not comment on the source code translation, this would also enable the compilation of country fans on her own way of thinking outside of the compilation of programming
