The Internet of Things is considered to be the next big opportunity, and challenge, for the Internet engineering community, users of technology, companies and society as a whole. It involves connecting embedded devices such as sensors, home appliances, weather stations and even toys to Internet Protocol (IP) based networks. The number of IP-enabled embedded devices is increasing rapidly, and although hard to estimate, will surely outnumber the number of personal computers (PCs) and servers in the future. With the advances made over the past decade in microcontroller,low-power radio, battery and microelectronic technology, the trend in the industry is for smart embedded devices (called smart objects) to become IP-enabled, and an integral part of the latest services on the Internet. These services are no longer cyber, just including data created by humans, but are to become very connected to the physical world around us by including sensor data, the monitoring and control of machines, and other kinds of physical context. We call this latest frontier of the Internet, consisting of wireless low-power embedded devices, the Wireless Embedded Internet. Applications that this new frontier of the Internet enable are critical to the sustainability, efficiency and safety of society and include home and building automation, healthcare, energy efficiency, smart grids and environmental monitoring to name just a few.

Welcome to the third volume of the book entitled Technologies for the Wireless Future, which is produced by WWRF. The idea is to take the most important outputs from the working groups and special-interest groups that compose the Forum and bring them together in a series of one-volume surveys. The latest of these will give the reader a good overview of the WWRF approach to analyzing the future of wireless and mobile communications, as well as an insight into the trends themselves and the key technologies that will be deployed.

In 2001, Orange, a UK mobile network operator, announced the “Orange at Home” project, a smart house incorporating the latest technology wizardry built some 20 miles north of London. It was intended to be more than a mere showcase, with plans for real families to move in and live with the smart home. My then research establishment, the Digital World Research Centre at the University of Surrey, was commissioned to study how these families reacted to their new home, and to report lessons for the future development of smart homes and smart home technologies.

In modern societies, the production and trade of goods all around the world is constantly increasing. The latest technological achievements allow the mass-production of millions of items of every kind, which are being exchanged all around the globe with unprecedented rapidity. At the same time, the problem of identifying, classifying and tracking such a growing multitude of objects is con- sequently arising.

n recent years, there have been many books published on power system optimization. Most of these books do not cover applications of artifi cial intelligence based methods. Moreover, with the recent increase of artifi cial intelligence applications in various fi elds, it is becoming a new trend in solving optimization problems in engineering in general due to its advantages of being simple and effi cient in tackling complex problems. For this reason, the application of artifi cial intelligence in power systems has attracted the interest of many researchers around the world during the last two decades. This book is a result of our effort to provide information on the latest applications of artifi cial intelligence to optimization problems in power systems before and after deregulation.

前言：由于之前聽(tīng)過(guò)太多人抱怨移植FreeRTOS到STM32有各種各樣的問(wèn)題，小燈經(jīng)過(guò)一年多對(duì)FreeRTOS的研究并在公司產(chǎn)品中應(yīng)用， 多少有些心得， 接下來(lái)就由小燈以最新版的FreeRTOS為例一步一步移植到STM32F103 上，并提醒大家某些需要注意的事項(xiàng)。本文檔為非正式技術(shù)文檔，故排版會(huì)有些凌亂，希望大家能提供寶貴意見(jiàn)以供小燈參考改進(jìn)。下面先以IAR 移植為例， 說(shuō)明移植過(guò)程中的諸多注意事項(xiàng)， 最后再以MDK移植時(shí)不再重復(fù)說(shuō)明，所以還是建議大家先花些時(shí)間看IAR 的移植過(guò)程，哪怕你不使用IAR，最好也注意下那一大堆注意事項(xiàng)！一、從官網(wǎng)下載最新版的FreeRTOS源碼下面的網(wǎng)址是官方最新源碼的下載地址：https://sourceforge.net/projects/freertos/files/latest/download?source=files目前官方提供的最新版本是v9.0.0 ， FreeRTOS 源碼在解壓目錄下的路徑為FreeRTOS_V9.0.0rc2\FreeRTOS\SourceFreeRTOS組織為了搶用戶(hù)也是拼了命的， 不信你打開(kāi)Demo文件夾看看， 里面提供了FreeRTOS在各種單片機(jī)上已經(jīng)移植好的工程，如果建工程時(shí)遇到什么問(wèn)題，可以參考下這些Demo。不過(guò)小燈現(xiàn)在著重于自己動(dòng)手移植FreeRTOS，考慮到原子哥@正點(diǎn)原子的用戶(hù)比較多，絕大多數(shù)習(xí)慣了使用MDK來(lái)開(kāi)發(fā)STM32，因此小燈分別以IAR 和MDK兩種使用比較廣泛的開(kāi)發(fā)環(huán)境來(lái)移植FreeRTOS。說(shuō)到IAR 和MDK，不得不提的是小燈自從用了IAR 之后就果斷放棄了MDK，相信很多人有這個(gè)經(jīng)歷，哈哈！在開(kāi)始移植FreeRTOS之前，先介紹下FreeRTOS的源碼：
