串行通信接口标准经过使用和发展，目前已经有几种,但都是在RS-232标准的基础上经过改进而形成的.RS-323C标准是美国EIA(电子工业联合会）与BELL等公司一起开发的1969年公布的通信协议。它适合于数据传输速率在0～20000b/s范围内的通信。该文档是对RS232C标准的详解.-serial communication interface standards through the use and development of that there are already several, but they are in the RS-232 standard on the basis of improved form of. RS-323C standard of the United States EIA (Electronic Industry Association) BELL companies together in 1969 to develop the communication protocol. It is suitable for data transfer rate of 0 ~ 20000b/s within the scope of communication. The document on the understanding the standard RS232C.

这个也是关于空间谱的matlab 挺好的 可以-This is on the spatial spectrum of matlab can be quite good

YAMAHA的铃音芯片的测试程序，用于40和弦的MA-3芯片。源代码为标准C编程。编译环境为TI的CCS，硬件环境为TI的OMAP1612。-YAMAHA rings chip testing procedures for 40 polyphonic MA-3 chip. Source code for the standard C programming. Environment compiler for TI"s CCS, the hardware environment for TI"s OMAP1612.

这是个很不错的编程代码，有关于RMI的是中科院的老师编写的有关网络电话的代码-this is a very good program code on the RMI Academy teacher preparation of the code of the telephone network

非常详细的modbus规范介绍，有串口的也有基于tcp的。。。。一书在手，modebus不用愁。。。。MODBUS标准分为三部分。第一部分（“Modbus协议规范”）描述了MODBUS事物处理。第二部分（“MODBUS报文传输在TCP/IP上的实现指南”）提供了一个有助于开发者实现TCP/IP上的MODBUS应用层的参考信息。第三部分（“MODBUS报文传输在串行链路上的实现指南”）提供了一个有助于开发者实现串行链路上的MODBUS应用层的参考信息。-very detailed Modbus standard, a serial port is based on the tcp. . . . A book in hand, do not have to worry about modebus. . . . MODBUS divided into three parts. The first part ( "Modbus protocol specification") describes the MODBUS handle things. The second part ( "MODBUS Packet Transmission in TCP/IP Implementation Guide"), provides a help developers to implement TCP/IP on the application layer MODBUS reference information. The third part ( "MODBUS Packet Transmission in the serial link achieve Guide"), provides a help developers achieve serial MODBUS link on the application layer of reference information.
