51汇编 三线驱动5片74HC595级联输出并由5片74HC165级联读回，有proteus仿真

定时器程序采用89c2051 -timer procedures used 89c2051

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.

Windows环境下32位汇编语言程序设计配套书源码第12章-Windows Environment 32-bit assembly language programming book source package Chapter 12

每名学生需要如下描述：学号、姓名、成绩。成绩保留小数点一位。试编制一程序完成学生的录入和输出。最终对所有学生的成绩进行从高到低的排序，并且输出排序结果，并且得出平均分，并且保留一位小数并且输出。-Needs of each student described as follows: Student ID, name, performance. Results 1 to retain a decimal point. Try to prepare a student entry process is completed and output. The final results of all students to sort from high to low, and the output of sorting results, and the average score obtained, and retained a decimal, and the output.

一款用于从avi视频中提取单帧图像数据的实例，本人第一次做，有兴趣者可以联系共同探讨。-A video from avi extract single frame image data of the examples, I make the first time, those interested can contact to discuss.

此程序的功能是实现不通过外设而直接发出声音,程序里用到主程序调用辅助的程序实现语言是汇编语言-this procedure is the function peripherals is not passed directly to voice their opinions. Lane procedures used in the main program called auxiliary program language is assembly language

试下发的上来不，同时，哎哟，搞点资料哦，好难-Examination of the table is not issued at the same time, Oh, come up with something the information Oh,好难
