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.

超级流水灯源程序，三种状态转化，用PWM及定时中断控制！-Super light water source, three state of transformation, using PWM and timer interrupt control!

汇编语言程序设计，显示系统时间。 首先在数据段开辟一显示缓冲区，用来存储系统时间。调用BIOS中断，返回系统时间，并将来返回的二进制时间转换成ASCII码，方便时间显示时的调用。分别将来小时数、分钟数、秒数存入显示缓冲区。通过写显存将时间显示出来。由于获取了的系统时间不会自动刷新，所以我们要设计成刷新的方式来不断获取系统的时间，这样就形成了会跳动的电子钟了。-Assembly language programming, display system time. First of all, open up one paragraph in the data display buffer for the storage system time. BIOS interrupt calls to return system time, and the future return of the binary time into ASCII code for the call time is displayed. Respectively, the future number of hours, minutes, seconds into the display buffer. Time by writing to memory will be displayed. As the access to the system time does not automatically refresh, so we need to refresh the way designed to keep on getting the system time, so that will be formed beating electronic o

固定值的加法。我用bx和ax作为寄存器。bx表示第一个固定值，ax表示第二个固定值，然后将其相加。

本程序实现系统时间查看.-system to examine.
