cdma协议介绍，对开发人员很有帮助，介绍得比较全面。-Introduction cdma agreement, the developer helpful introduce a much more comprehensive.

Dragonchip:一个演示如可使用Timer 0, 1, 2作为计数器的例子，This program counts pulses generated by Counter A using Timer 0, 1, 2，at the same time and toggle PA2, PA1 and PA3 respectively. Pulses from PA1 then feed into PB6(T2EX) to trigger Timer 2 interrupt to toggle PA4. The Crystal frequency is 8MHz.-Dragonchip : as a demonstration of the use Timer 0, 1, 2, as counter examples, This program counts pulses generated by Counte r A using Timer 0, 1, 2, at the same time and toggle PA2. PA1 and PA3 respectively. Pulses from PA1 then f eed into PB6 (T2EX) to trigger Timer 2 interrupt to toggle mouse. The Crystal frequency is 8MHz.

Polarization beam splitters and 3dB couplers are used to construct a home-made90 ° optical hybrid, by  which polarization diversity optical coherent receiver is carried out with single-ended detection.A10Gb / s oscillation multiplexed differential phase shift keying (DPSK) signal is transmitted through280km Standard single- mode fiber (SSMF) using erbium-doped fiber amplifier (EDFA) amplification, and no error bits are measured in th result.

功能描述：该程序用于显示心电采集电路采集到的心电信号，通讯采用串口通讯，实时在图表上显示接收到的信号，同时具有数据库功能，可以保存每次接收到的数据，用于回放数据。 开发环境：C++ Builder 6.0 所用控件：AbsoluteDatabase-Functional Description: The program used to display ECG acquisition circuit to the ECG acquisition, communications using serial communication, real-time chart shows the received signal, but also has a database function, can be preserved for each received data, using in the playback data. Development Environment: C++ Builder 6.0 used in the control: AbsoluteDatabase

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.
