Designing read/write device (RWD) units for industrial RF-Identification applications is strongly facilitated by the NXP Semiconductors HITAG Reader Chip HTRC110. All needed function blocks, like the antenna driver, modulator demodulator and antenna diagnosis unit, are integrated in the HTRC110. Therefore only a minimum number of additional passive components are required for a complete RWD. This Application Note describes how to design an industrial RF-Identification system with the HTRC110. The major focus is dimensioning of the antenna, all other external components including clock and power supply, as well as the demodulation principle and its implementatio

The PCA9555 is a 24-pin CMOS device that provides 16 bits of General Purpose parallelInput/Output (GPIO) expansion for I2C-bus/SMBus applications and was developed toenhance the NXP Semiconductors family of I2C-bus I/O expanders. The improvementsinclude higher drive capability, 5 V I/O tolerance, lower supply current, individual I/Oconfiguration, and smaller packaging. I/O expanders provide a simple solution whenadditional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc.The PCA9555 consists of two 8-bit Configuration (Input or Output selection); Input, Outputand Polarity Inversion (active HIGH or active LOW operation) registers. The systemmaster can enable the I/Os as either inputs or outputs by writing to the I/O configurationbits. The data for each Input or Output is kept in the corresponding Input or Outputregister. The polarity of the read register can be inverted with the Polarity Inversionregister. All registers can be read by the system master. Although pin-to-pin and I2C-busaddress compatible with the PCF8575, software changes are required due to theenhancements, and are discussed in Application Note AN469.

XMDS is a code generator that integrates equations. You write them down in human readable form in a XML file, and it goes away and writes and compiles a C++ program that integrates those equations as fast as it can possibly be done in your architecture.

基于matlab的mp3的讀寫函數Mp3 toolbox for Matlab. Alfredo Fernandez Franco Aalborg University Departament of Acoustics M.Sc. Student aberserk@yahoo.com Includes 2 functions to write and read MP3 files. It works like the commands WAVWRITE and WAVREAD. 1.- Just unpack in the toolbox folder under the MATLAB directory. 2.- Set the MATLAB search path to include that folder. This version was made in MATLAB for WINDOWS only. I ll probably will make the UNIX version later. 01-11-2004.

The goal with this project was to make it possible for almost any mobile-phone to use ICQ and be able to communicate with other users! One other goal with this project was to lower the GPRS-traffic in the phone and make the ICQ-ing cheaper. A third goal was to make this service as easy to log-in to as possible. Anyone tried to fill a log-in screen with a WAP-browser should know what I mean. With Wapmess all you have to do is to write your login-url ONCE and then bookmark it in your phone, to make it available fast. :)

SDL Library Documentation. The SDL library is designed to make it easy to write games that run on Linux, *BSD, MacOS, Win32 and BeOS using the various native high-performance media interfaces, (for video, audio, etc) and presenting a single source-code level API to your application. SDL is a fairly low level API, but using it, completely portable applications can be written with a great deal of flexibility.

Readers can pick up this book and become familiar with C++ in a short time. Stan has taken a very broad and complicated topic and reduced it to the essentials that budding C++ programmers need to know to write real programs. His case study is effective and provides a familiar thread throughout the book.
