Usb通信程序开发示例，讲述如何开发一个USB应用用程序

VC中采用HTML实现可配置输入界面的模拟测试通信程序，是我自己做的，已投入使用-VC used HTML configurable input interface simulation testing communication procedures, I do for myself, has been put into use

这是一个通讯软件-This is a communications software

COM编程入门知识!对COM的初步了解!-portal COM programming knowledge! COM to the preliminary understanding!

can总线通信VB6源程序。用于编写can通信协议，以及测试can总线。-can bus communication VB6 source. Can prepare for the communication protocol and can test bus.

这是关于VC与单片机串口通信的资料,学习后很受启发,-on VC and SCM serial communication of information, after learning a great deal of enlightenment.

已成功实现串口通讯测试，并可移植到其他的c#项目中去，该程序不是调用c sharp 控件实现的！是通过自建类文件实现的！移植起来也相当的方便，可根据自己需要增加16进制发送和接收，程序代码已注释，可根据情况修改和进行二次开发！

电力设备CDT协议,介绍比较详细,希望有用-Electrical equipment CDT agreement to introduce the more detailed the hope that useful

Sigma调制功能，便可提高其频率精度，大幅降低相位噪音及带内杂散信号，并???持极高的切换速度。系统设计工程师可以利用 Delta Sigma PLL将比较频率提高到很高的水平，以大大降低相位噪音。但高比较频率会导致产生周期滑动(cycle slipping)现象。-Sigma modulation function, can increase its frequency accuracy, dramatically reducing the in-band phase noise and spurious signals, and??? Holders of high switching speed. System design engineers can take advantage of Delta Sigma PLL compares the frequency increased to a very high level in order to significantly reduce the phase noise. However, the high comparison frequency would result in sliding cycle (cycle slipping) phenomenon.
