modbus串口通信，利用vc6.0控件自己的项目中用到的代码，很好用。里面有两个程序，一个上位机，一个模仿下位的极的程序，可以互相通信。-modbus serial communication, the use the code the vc6.0 controls used in the project, to very good use. There are two programs, a host computer, an imitation of a bit extreme progr

这是一个去极值滑动窗口数字滤波器算法，在ADC采样的时候可以用这个算法去除脉冲干扰。-This is digital filter algorithm which removes extreme value，and it works just like a sliding window, we can use this algorithm to remove glitches in ADC sampling。
