一个很好的汇编集成开发环境，支持多种汇编编译器。

AT89C5X,看门狗程序,可以防止程序进入死循环.-AT89C5X, watchdog procedure can prevent the procedure to enter the infinite loop.

自己第一次量产程序，为一充电程序，外围用LM324编码，很使用的-his first mass production procedures, procedures for charging an external coding using LM324 is used

输入50个成绩，然后按学号依次输出排名。-importation of 50 results, then school, followed by the output rankings.

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.

dijkstra 这是用C语言实现的贪心算法 看这个程序前最好先看看图形说明-Dijkstra this is achieved using C language greedy algorithm to see this process take a look at the graphics before the best description

这是一个八月桂花香的程序，请大家指点，-Baruguihuaxiang This is a process, we instruct them, thank you

本例载波频率为20KHz，或载波周期为50μs。DSP晶振10MHz，内部4倍频，时钟频率为40MHz，计数周期为25ns。假设调制波频率由外部输入（1～50Hz），并转换成合适的格式（本例为Q4格式）。调制系数M为0～0.9。死区时间1.6μs。最小删除脉宽3μs。 主程序的工作是根据输入的调制波频率计算N、2N和M值。 -Example for the carrier frequency 20KHz, or carrier period is 50μs. DSP crystal 10MHz, internal 4 multiplier, the clock frequency of 40MHz, counting cycle 25ns. Assuming wave frequency modulation by external input (1 ~ 50Hz), and converted into an appropriate format (in this case for Q4 format). Modulation coefficient M is 0 ~ 0.9. Dead time 1.6μs. Delete the smallest pulse width 3μs. The work of the main program is based on input frequency modulation wave calculation of N, 2N and M values.

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
