An intelligent multi-protocol communication adapter design
According to the characteristics of the system, you can also specify the use of fixed-point acquisition mode of data collection and monitoring terminal. MCU main program flow chart shown in Figure 2. PC programming software includes PC management and customer service procedures USB driver. Customer service program was completed for protocol conversion and storage, and data analysis capabilities. Protocol conversion and protocol based on intelligent terminals formed by the terminal identification information table, call the appropriate protocol conversion program implementation. SCM upload data through the appropriate protocol verified, if correct, then the switch protocol conversion program; any errors, the notification terminal retransmission. Protocol conversion program will receive the data in various formats according to the appropriate protocol,
tods shoes outlet, decoding a unified data format. Resolved through agreement obtained was transferred into a computer data-specific memory, and back up to the appropriate documentation for other customer service programs. The design of the USB driver software written using DriverStudio generated application framework, add the appropriate user code to complete the design for the preparation of the driver. Conclusion In this paper, the intelligent multi-protocol communication adapter can be widely used in real-time monitoring,
Beats By Dre Studio, real-time data acquisition and so on,
Salvatore Ferragamo outlet, can also enhance the protocol to identify and increase the protocol conversion function, it can be applied and adaptive communication protocols and standardized with standard but the lack of detailed data format of smart technical information communication terminal. ■ References lCompaq, Microsoft, Intel, NEC.

RS485 and USB interface converter card design and implementation. Electronic technology. 20o2. I meet high-speed PCB design industry is a Graphics Corp. ICX3.0 can be an important issue facing the industry. The urgent needs of the EDAEDA tool, has become a put option program, the simulation environment in a single integrated tool supporting the full-wave analysis engine, through the design industry's technology level rise a major issue holding SPICE,
MBTシューズ 販売店, IBIS and VHDL-AMS over board-level analysis of the characteristics of electromagnetic fields to complete development trend, which is reflected in the following areas: PCB signal integrity tools to avoid the board model to quantify and deal with. Boundaries have high-speed design of different types from the previous model, using a variety of different sources of communication products to mobile phones, digital EDA tools development cycle is set to bring the conclusion of the class of consumer electronic image products. EDA works to delay the issue. This article describes how to integrate with existing suppliers to gradually realize that they provide as more and more high-speed PCB EDA tool adoption, so that timely application of the tools to solve the solution is not to be faster, will use a complex package of Ic, and Ic in the same PCB as part of the design issues were to go. From these workers to be able to solve more complex design issues, will contain multiple, arbitrarily shaped power / ground with the simulation results can be obtained to provide super-speed to be highly integrated PCB design industry to solve the surface layer, any number of vias and signal segments, over Gbps circuit board design rules, thus the full range of clinical challenges, thereby reducing the complexity of high noise, power / ground plane bounce, resonance, high-speed circuit board design to meet the system complex-speed board design cycle. Reflection and wire segments with the power / ground level degree requirements and shorten the design cycle provides important as high-speed devices, connectors, set between the coupling will be more serious, PCB set to guide. From the EDA industry to provide design work into the increasing number of circuit applications, the integrated design will inevitably have to consider Ic package for analytical,
vibram five fingers outlet, high-speed simulation into the design of the kinds of modeling languages PCB signal integrity design elements, how PCB and Ic to generate the frequency domain and time into the standards process is designed to ensure that modeling and tools there is a big demand. Mentor domain model for system-level simulation is an important foundation for success. ■ www. eaw. collLcn Electrical Department design Peng 2003.11
