This is IR (Infra-Red) learn module for home automation system. It can learn IR codes from different IR remotes, and then execute any assigned Actions controlled by learned IR remote. This project was developed using Keil 8051 compiler. Processor - Atmel AT89C51 Frequency - 22.1184 Mhz (described as OSC_FREQ in "timer.h") Timer 0 - system timer (used for timeouts and delays) Also, look in folder /doc for additional information about IR codes formats and codes from different manufacturers.

Eclipse is the leading Integrated Development Environment (IDE) for Java, with a rich ecosystem of plug-ins and an open source framework that supports other languages and projects. You’ll fnd this reference card useful for getting started with Eclipse and exploring the breadth of its features. We rundown the Eclipse distributions and confguration options, then guide you through Views, Editors, and Perspec- tives in Workbench 101. We list the top shortcuts and toolbar Actions for everyday development. And, we provide a guide to the best places for fnding plug-ins and getting involved with the Eclipse community.

This books presents the research work of COST 273 Towards Mobile Broadband Multimedia Networks, hence, it reports on the work performed and on the results achieved within the project by its participants. The material presented here corresponds to the results obtained in four years of collaborative work by more than 350 researchers from 137 institutions (universities, operators, manufacturers, regulators, independent laboratories and others – a full list is provided in Appendix B) belonging to 29 countries (mainly European, but also from Asia and North America) in the area of mobileradio. Theobjectiveofpublishingtheseresultsasabookisessentiallytomakethemavailable to an audience wider than the project. In fact, it just follows a ‘tradition’ of previous COST Actions in this area of telecommunications, i.e. COST 207, 231 and 259.

The first practical examples of mobile communications were used in many countries like the USA, the UK and Germany in military services, and played a significant role in the First World War to transfer important information from the front to headquarters to take further Actions. Good and secure wireless communications were an important need for all military services – army, navy and air force. In this respect, the Second World War was a big experimental battlefield for the development and evolution of mobile radio. It was in the interests of governments that after the Second World War the military investment should be paid back by civilian use, and all western European countries started their so-called first generation of mobile communication networks.

ATS2819/ATS2819P标准应用方案主要分为以下功能模块：Power Supply，BlueTooth，Audio Input/Output（包括codec、I2C、SPDIF），FM Receiver，disaplay（LED&LCD），USB，SPI NOR Flash Memory，SD/MMC/MS Card等。1.2原理图设计总体原则1原理图设计需要按照方案规格的要求实现各项硬件功能，尽量避免功能模块相互间的资源冲突。如果存在I/O复用，接收复用等情况，除了需注意检查I/O上电状态，接口时序等，还需要注意复用的SIO工作频率与工作电压域是否符合要求(如WIO)，确保功能设计正确实现。2原理图设计要求性能达到要求。如稳定性，启动电压，功耗，ESD，EMI等。要注意检查模块电源开关状态，选择的原件标称及精度、材质，接口保护元件和EMI滤波器等。3系统时钟26MHZ，要求CL为7~9PF，精度为+-10PPM。这样才能保证系统能正常工作。4当设计PCB受限于模具大小时，各个模块无法保证均能得到最优的布局布线(如滤波电容要求靠近IC、走线上要求尽量少的过孔与尽可能短的走线)。因为在此给出一个模块优先级以供设计人员参考，从而提高方案设计的效率，增加一版work的可行性。将优先级以阿拉伯数据排列
