When joining Siemens in 2001, I also extended my research interest towards radio net- work planning methodologies. This area of research brought together my personal interest in mobile communications and in the design of efficient algorithms and data structures. Between 2001 and 2003, I participated in the EU project Momentum, which was TARGET- ing the performance evaluation and optimization of UMTS radio networks. I

Since the 1990s the EU has been pursuing climate change mitigation TARGETs. Following the international commitment to the legally binding greenhouse gas reduction under the Kyoto Protocol, the 2020 policy package consists of a set of binding legislation to ensure that the EU meets its climate and energy TARGETs for the year 2020. The package sets three key TARGETs: 20% reduction in greenhouse gas emissions (from 1990 levels), 20% of EU energy from renewables (as well as a 10% TARGET for renewable fuels) and 20% improvement in energy efficiency. The TARGETs were set by EU leaders in 2007 and enacted in legislation in 2009 3 . They are also headline TARGETs of the Europe 2020 strategy for smart, sustainable and inclusive growth.

Identification is pervasive nowadays in daily life due to many complicated activities such as bank and library card reading, asset tracking, toll collecting, restricted access to sensitive data and procedures and TARGET identification. This kind of task can be realized by passwords, bio- metric data such as fingerprints, barcode, optical character recognition, smart cards and radar. Radiofrequencyidentification(RFID)isatechniquetoidentifyobjectsbyusingradiosystems. It is a contactless, usually short distance, wireless data transmission and reception technique for identification of objects. An RFID system consists of two components: the tag (also called transponder) and the reader (also called interrogator).

Radio frequency identification (RFID) technology is witnessing a recent explosion of development in both industry and academia. A number of applications include supply chain management, electronic payments, RFID passports, environmental monitoring and control, office access control, intelligent labels, TARGET detection and tracking, port management, food production control, animal identification, and so on. RFID is also an indispensable foundation to realize the pervasive computing paradigm—“Internet of things.” It is strongly believed that many more scenarios will be identified when the principles of RFID are thoroughly understood, cheap components available, and when RFID security is guaranteed.

首先下載軟件，解壓軟件，安裝在程序中找到SEGGER,選里面的J-FLASH，進入界面，剛開始的那個界面可以忽略，不用建project也可以；單擊菜單欄的“Options---Project settings”打開設置，進行jlink配置;正在General選項，選擇“USB”，一般都是默認配置，確認一下即可;然后在CPU選項，選擇芯片型號，先選擇“Device”才能選擇芯片型號，芯片型號，要根據你使用的芯片進行選擇;在TARGET interface選項 里面選擇SWD模式;首先TARGET里面選“Connection”連接目標芯片，然后 TARGET--Auto進行程序燒寫;首先TARGET里面選擇“Connection”連接目標芯片，然后 TARGET--Auto進行程序燒寫.SEGGER J-Links are the most widely used line of debug probes available today. They've proven their value for more than 10 years in embedded development. This popularity stems from the unparalleled performance, extensive feature set, large number of supported CPUs, and compatibility with all popular development environments.
