基于verilog的HDB3编码器的实现

串口通讯程序,用vc写的很好的说明了用API涵数进行串口的读和写!- The string mouth communication procedure, very good showing which wrote with vc has contained the number with API to carry on the string mouth to read and to write!

同学录系统是一个用asp.net开发的程序-college system is an Asp. Net with the program

用IIR滤波器实现去除信号中的直流分量.用很少的资源实现去除直流分量的功能。-remove the DC vector from the signal。implement the DC removing function using little resource.

这是一个综合了多种通信方式(RS232串口/TCP/UDP/E1)的通信接口类,它对外提供了统一的接口,使得开发人员不再需要关心通信编程的细节! 内部使用多线程,效率极高,并且经过了2年的使用,不断的得到维护,目前最新版本.-This is a combination of various means of communication (RS232 serial/TCP/UDP/E1) Communication Interface category, which offer a unified interface that allows developers no longer need to care about the details of the Communication Programming! The internal use of multithreading and efficient way, and after two years the use of continuously maintained that the latest version.

用C及ftp实现软件自动升级。通过在服务器端建立FTP服务,实现远程主机的文件更新. 软件启动过程连接服务器,获得软件文件更新列表(此步省略),进行本地文件更新 启动过程进行系统调用执行批处理文件ftpget.bat,调用方式system( "e:ftpget.bat" ) 文件ftpget.bat负责连接服务器下载所需文件,并完成文件的更新-C ftp software and automatic upgrades. Through the establishment of FTP server, remote mainframe file updates. Software startup process server connectivity, access to software updates list (this step is optional), a local paper started the process of updating system calls for the implementation of batch file ftpget.bat, call mode system ( "e : ftpget.bat") documents ftpget.bat for connecting servers to download the necessary documents, and complete the document update
