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.

用直流无刷电机控制电动门的运转,可已省掉机械定位装置-Brushless DC motor control with electric door operation, may have saved mechanical positioning device

实现8251可编程通信实验的汇编源代码 使用环境是星研集成环境-8251 programmable communication experiment to achieve the compilation of source code for the use of the environment is an integrated environment for satellite research

交通灯控制源程序，包括各相位、可保存多种方案在E2ROM,可根据需要调整方案。-Traffic lights control the source, including the phase, multiple programs can be stored in E2ROM, may need to be adjusted in accordance with the program.

WinAsm32的确是一本好的教材,不管你是初学者,还是高手,都能从它里面学到很多的东西.-WinAsm32 is a good material, whether you are a beginner or expert, can learn from the inside many things.

利用汇编语言实现的一个打字练习程序，程序界面为典型的Dos窗口，当字符从窗口顶端掉下来后，如果按键与该字符相同，字符变为红色，在打字结束后，给出打字的统计结果，在打字过程中按ESC可退出程序-The use of assembly language to achieve a typing practice program, the program interface for the typical Dos window, when the characters fall from the top window, if the button with the same characters, the character turns red, in the typing after the end of typing results is given , in the typing process by pressing ESC to exit

它是一个基于单片机计算器，其完全工作使用 1 k 或 10 k 锅的 lcd 对比度控制销而不是使用 1 只 10k 的电阻上其上运行的代码

由汇编语言编写的基于DS18B20的多点温度检测程序源码，程序调试通过，不用作改动就可以运行在单片机系统中。-Prepared by the assembly language DS18B20 based multi-point temperature of the source detection procedure, program debugging through, do not make changes to be able to run in single-chip system.
