Release Notes for IDT77222/252 Windows NDIS5 ATM Device Driver, version 1.3

这是一个表现蝴蝶飞飞的小程序的设计，只是一个小小的尝试，希望大家多多指导。(This is a performance of small butterflies soaring procedures designed only to a small, I hope Members can guide.)

C Programming for Microcontrollers

说明：  fe-cu-mn-ni合金的相场模拟程序(Phase field simulation program for fe-cu-mn-ni alloy)

visual C＋＋环境下，获取网卡的地址，从中可以学习硬件编程方面的知识。-visual C++ environment, the access network card address, can learn from the hardware programming knowledge.

说明：  用通达信接气接口来保存A股历史数据到Mysql数据库(using python Tdx to mysql)

1）设计Butterworth型音频抗混叠滤波器； 2）参数： 下通带频率300Hz；上通带频率3400Hz； 下阻带频率280Hz；上阻带频率3600Hz； 通带最大衰减0.3dB； 阻带最小衰减40dB； 3）采用一低通滤波器和一高通滤波器级联； 4）分别确定LPF和HPF的性能指标； 5）求出两滤波器的系统函数和频率响应，并画出其幅频特性曲线； 6）求整个滤波器的系统函数和频率响应，并画出其幅频特性曲线。(1) the design of Butterworth-type audio anti-aliasing filter 2) parameters: passband frequency of 300Hz on pass-band frequency 3400Hz under the stop-band frequency of 280Hz on stop-band frequency 3600Hz passband maximum attenuation of 0.3dB minimum stopband attenuation of 40dB 3) the use of a low-pass filter and a high-pass filter cascade 4) separately to determine the performance of LPF and HPF target 5) to derive two-filter system function and frequency response, and draw its increase frequency characteristic curve 6) for the entire filter system function and frequency response, and draw its amplitude-frequency characteristic curve.)

说明：  利用管道通信的一个demo，c++管道实现利用了命名管道的方法(Using a demo, C + + pipeline for pipeline communication, the method of named pipeline is used)

关于时间校验的的两个小例子。含源码。有用就拿来用吧。-check the time on the two small examples. With the source code. Useful for use on it.
