scanf的python实现,实现类似c++里的sscanf的东东，有些瑕疵，多多catch(scanf realization of python)

CRC check 介绍CRC的基本原理以及实现方式(CRC check)

它是一个可以记录用户键盘操作的间谍软件。黑客可利用此软件记录用户输入的信息。此软件和病毒完全不同，是正规软件，目前大概有两类软件。一类是模仿操作，用途是做重复操作 　　按键精灵就是其中之一；还有一类是用于家庭监控的软件，如梦真工作室开发的键盘屏幕全记录。(The virus is completely different from a regular software, currently there are about two types of software. A class is to imitate the operation use repeat QuickMacro there is a class of software for home monitoring, keyboard screen Full Record dream real studio.)

该工程主要用的是C语言，控制器是89C52编译环境是Keil uVision4，其功能是实现特定波形输出后，通过控制数字电位器MCP41010来实现波形信号的5种频率的传输。(The project mainly use the C language, the controller is the 89C52 compilation environment KEIL the uVision4, its function is to achieve a specific waveform output, to achieve transfer of the five kinds of frequency of the waveform signal by control digital potentiometer MCP41010.)
