代码说明:

STM32的每个TIMER都有正交编码器输入接口,TI1,TI2经过输入滤波,边沿检测产生TI1FP1,TI2FP2接到编码器模块,通过配置编码器的工作模式,即可以对编码器进行正向/反向计数.编码器使用了A,B两相信号,但是我只需要对TI1信号进行计数(第一行),我也是刚发现了这个错误,原来对两个信号都计数,导致码盘转一周得到不止100个脉冲(100线的光电码盘)。通过STM32的编码器模块比较两想的电平信号就可以很容易地计算出编码器的运行情况了

  • C语言写的搜索引擎
    C语言写的搜索引擎,索引由以下几个基本的组成部分:1. 倒排索引,这一部分存放"关键字"->文档的映射,一般来说会把同一个关键字对应的所有文档按照统一方法整理成一个排好序的线性结构,以便遍历和各种AND/OR之类的操作。

    XueTr算是目前最强的反rootkit工具了,本程序完成了对Xuetr的注册表项的隐藏,采取的方式是驱动绕过,而不是简单的GUI HACKER。(XueTr considered to be the most powerful anti-rootkit tool, the program completed Xuetr hidden registry keys, takes the form of driving around, rather than a simple GUI HACKER.)
