The development of programming Firmware、device driver and user application are thoroughly researched.Key words: AN2131Q; TMS320C5409; IDT72V02; data communication
In this paper, we describe the development of a mobile butterfly-watching learning (BWL)
system to Realize outdoor independent learning for mobile learners. The mobile butterfly-watching
learning system was designed in a wireless mobile ad-hoc learning environment. This is first result
to provide a cognitive tool with supporting the independent learning by applying PDA with
wireless communication technology to extend learning outside of the classroom. Independent
learning consists of self-selection, self-determination, self-modification, and self-checking.
water temperature control system uses the Single Chip Microcomputer to carry on temperature real-time gathering and controling. DS18B20, digitized temperature sensor, provides the temperature signal by "a main line". In -10～+85℃ the scope, DS18B20’s inherent measuring accuracy is 0.5 ℃. The water temperature real-time control system uses the electricity nichrome wire carring on temperature increiseament and operates the electric fan to Realize the temperature decrease control. The system has the higher measuring accuracy and the control precision, it also can complete the elevation of temperature and the temperature decrease control.
Realizing an MP3 player with the LPC2148, using libmad and
EFSL This Application Note describes how to integrate the libmad MPEG 1/2 layer 3 library and
the Embedded File System Library EFSL in a LPC2148 device to Realize MP3 player.
The Keil MCB2140 board is used to test the application and the Rowley CrossStudio for
ARM has been chosen as a reference tool-chain.
R1EX24xxx series are two-wire serial interface EEPROM (Electrically Erasable and Programmable
ROM). They Realize high speed, low power consumption and a high level of reliability by employing
advanced MNOS memory technology and CMOS process and low voltage circuitry technology. They
also have a 128-byte page programming function to make their write operation faster.
Note: Renesas Technology鈥檚 serial EEPROM are authorized for using consumer applications such as
cellular phone, camcorders, audio equipment. Therefore, please contact Renesas Technology鈥檚
sales office before using industrial applications such as automotive systems, embedded controllers,
and meters

Welcome to HyperString!
One of the most significant new features with Delphi32 is long dynamic
strings. However, the built-in functions don t really exploit the full
potential of these new strings. HyperString provides over 400 fast,
efficient string management routines to help you Realize the full power
of this highly versatile new data type.
jamod is an object oriented implementation of the Modbus protocol, Realized 100 in Java. It allows to quickly Realize master and slave applications in various transport flavors (IP and serial).
Java technology has evolved from a programming language designed to create
machine-independent embedded systems into a robust, vendor-independent,
machine-independent, server-side technology, enabling the corporate community
to Realize the full potential of web-centric applications.
Java began with the release of the Java Development Kit (JDK). It was obv
Finally, after a great deal of effort and hard work, you have obtained
the results you were trying to get for such a long time. You may be
so busy (and tired) that you don’t even Realize that you have indeed
achieved a certain measure of success. Perhaps it will take a fewmore
months before you can present your work at a conference or submit it
to a scientific journal.
This thesis is about wireless communication in shared radio spectrum. Its origin and
motivation is ideally represented by the two quotations from above. In this thesis, the
support of Quality-of-Service (QoS) in cognitive radio networks is analyzed. New
approaches to distributed coordination of cognitive radios are developed in different
spectrum sharing scenarios. The Wireless Local Area Network (WLAN) 802.11 proto-
col of the Institute of Electrical and Electronics Engineers (IEEE) (IEEE, 2003) with
its enhancement for QoS support (IEEE, 2005d) is taken as basis. The Medium Access
Control (MAC) of 801.11(e) is modified to Realize flexible and dynamic spectrum
assignment within a liberalized regulation framework.
