AD9851的应用程序，经验证可以正常使用-AD9851 application, normal use can be proven

可在系统引导时工作的RootKit,较简单 1) It s very small.The basic framework is just about 100 lines of assembly code.It supports 2000,XP,2003 2) It patches the kernel at runtime(no files are patched on disk).(basic version has this code removed , so as others could understand it easily). 3) BOOT KIT is PXE-compatible. 4) It can even lead to first ever PXE virus 5)It also enables you to load other root kits if you have physical access(Normally root kits can only be loaded by the administrator)-the system can guide the work of Rootkit. simple 1) It"s very small.The basic framework is jus t about 100 lines of assembly code.It supports 2 000, XP, 2003 2) It patches the kernel at runtime (no file "s are patched on disk).

外部中断与Timer中断同时存在的实验 （单片机）-External interrupt Timer Interrupt-exist with the experimental

微机原理实验的程序，包括8255，8253，8259-Principle of Microcomputer experimental procedures, including 8255,8253,8259

手机中用的I2C代码,包含GPIO口说明-phone using I2C code, the oral statement contains GPIO

通过汇编语言设计一个小程序来求一个数的阶乘-Through assembly language to design a procedure to seek a small number of factorial

反汇编，机器码转成汇编代码——对输入的机器码要求：不要用二进制，用十六进制。也就是原来32位的2进制机器码改成8位的16进制机器码。(Disassemble, turn the machine code into assembly code- the input machine code requirements: Do not use binary, hexadecimal. That is the original 32-bit binary machine code into eight hexadecimal machine code.)

此程序实现简单红绿灯的模拟控制，结构简单、易懂，可以在学校实验室试验箱上模拟练习！-Realize this procedure a simple simulation of traffic light control, simple structure, easy to understand, you can in the school laboratory chamber simulated exercises!

用汇编语言编程，环境为keilC开发环境，显示温度-Using assembly language programming, the environment keilC development environment, shows that the temperature

本代码为本人基于汇编语言的51单片机课程上机考试程序。;实验要求;利用P1/P2口或8255的接口电路和实验台上提供的六个数码管显示，设计一个电子钟，;电子钟设计如下格式   XX XX XX由左向右分别为时、分、秒;本人采用定时器溢出中断确定时间基准，main函数对共阴数码管进行动态扫描;p1口作为位选信号输出端;P2口作为段选信号输出端
