Description: 都是主从板程序，用于zigbee研发，硬件是飞思卡尔的13192sard板。使用时将此程序覆盖掉飞思卡尔所出的smac子程序里的source code即可，主要功能都是通信，而第三个是自动组网程序，主板上电后会将后来上电的sard板加进网络。
编译环境是codewarrior，此编译器使用许可需要购买，16k以下可以免费申请向官方申请。
目前程序很简单，但是编译环境很苛刻，很多人可能没法拿到codewarrior，不过希望能帮到大家。
用途是zigbee，这边没那选项，只好投到相近的RFID领域，毕竟很多是相通的-are from the main board procedures, zigbee for research and development, Freescale's hardware is the 13,192 sard plate. Use this program coverage swap Freescale's out of a subroutine smac Lane will be the source code. Communication is the main function, and the third is the automatic network procedures, on the Main Board-- will be later after the sard plate-- into the network. Codewarrior compiler environment, the compiler need to buy a license, 16k following free application to the official application. The current procedure is very simple, but the build environment is very harsh, many people might not be able to get codewarrior. But we hope to be able to help. Use is zigbee, then no options here, but in places where similar RFID field, after all, many are interchangeable

Description: 根据曼彻斯***的编码原则（参见本刊2001年第一期《一种采用曼码调制的非接触IC卡读写程序编制》），非接触ID卡采用上升沿对应着位数据“0”，下降沿对应着位数据“1”，微控制器通过检测U2270B输出数据位的跳变来实现对曼彻斯***的译码。在现实工作中，数据信号会受到调制、解调、噪声各种效应的影响，其上升沿和下降沿存在抖动，可采用键盘消抖的办法来消除抖动的影响。根据非接触ID卡64位数据循环发送以及其数据绪构特点，即数据流中第64位为“0”，第1位至第9位为“1”。据此，将“0111111111”作为读数据的起始标识，如图2所示。在确定了数据起始标识后，采用延时大于0.5T采样数据位的方法，如图3所示，来避开曼彻斯***编码中的空跳对数据译码造成的影响，简化了译码程序。
通过实验得到：480μs≤1T≤520μs，220μs≤0.5T≤280μs，由此取Tnext=300μs。为了便于对读出数据进行奇校验，读出数据每5位作为一个字节。因此确定起始标识和读取数据对时钟有严格要求，所以寻找起始标识和读取数据部分程序采用汇编语言编写。数据读以后，根据前面所提到的非接触ID卡的数据结构，通过比较奇校验算法与读出数据中的奇校验位来验证出数据的正确性。-A man code modulation non-contact IC card reader Programmer

Description: RFID – An introduction
RFID tags, security and the individual-When I lastwrote for CSLR, RFID tagswere but a glimmer in
some scientist’s eye. The thought that by 2006 they would be
in everyday use [even if we did not know it] was unthinkable.
However, the fact is that technology hasmoved on and RFID is
the next big thing – or rather the next very small thing, as the
major advances in technology relate to miniaturisation.

Description: RFID, the wireless technology that has helped
millions of people around the world to protect their property and
make their workplaces safer is now in danger of being viewed as a
security risk. Ray Stanton examines the love-hate relationship
between people and Radio Frequency Identification [RFID] tags and
highlights the need for informed debate about the privacy issues the
technology raises.-Sometimes it seems we have a love-hate
relationship with technology, and that’s
certainly the case with RFID.
On the one hand, the tags are just
high-tech barcodes – attached to items
to allow them to be tracked through the
supply chain and make life easier at
supermarket checkouts.

Description: A major problem with RFID systems is that a tag might not be read, in spite of being in
the reader’s range, due to collisions[4]. A collision is said to have occurred when various
devices interfere with each others’ operations, or their simultaneous operations lead to
loss of data. The reading process is not efficient due to various types of collisions, which
are classified as follows :-
• Single Reader-Multiple Tags collision : Multiple tags are present to communicate
with the reader. They respond simultaneously and reader is not able to interpret
the signal.
• Single Tag-Multiple Readers collision : Single tag is in the range of two or more readers.
Tags are mainly passive entities, they do not have enough power to differentiate
between frequency range of the readers.
• Reader-Reader interference : Two or more readers within the same frequency range
interfere with each others’ operations.-A major problem with RFID systems is that a tag might not be read, in spite of being in

Description: Covering both passive and active RFID, the challenges to RFID implementation
are addressed using specific industry research examples as well as common
integration issues. Key topics such as performance optimization and evaluation,
sensors, network simulation, RFID in the retail supply chain, and testing are
covered, as are applications in product lifecycle management in the automotive
and aerospace sectors, in anti-counterfeiting, and in health care.
This book brings together insights from the world’s leading research
laboratories in the field, including MIT, which developed the Electronic Product
Code (EPC) scheme that is set to become the global standard for objectidentification.
