This application note discusses a variety of approaches for interfacing analog signals to 5V powered systems. Synthesizing a "rail-to-rail" op amp and scaling techniques for A/D converters are covered. A voltage-to-frequency converter, applicable where high resolution is required, is ALSO presented.

CSL is a programming language with C syntax and comprehensive libraries. The compact scripting engine can ALSO be embedded into your own applications as a powerful macro language. Windows Distribution utilities.
FFmpeg is an audio/video conversion tool. It includes libavcodec, the leading open source codec library. An experimental streaming server for live broadcasts is ALSO included
Java Clock is a FREE Java applet used to display a clock on your Web pages. You can display either analog or digital clock. The full source code of this applet is ALSO available (visit my home page to download it). You may use this applet on your Web pages WITHOUT paying me fee or royalty as long as credit is given (a link to my home page is enough).
Antinat is a flexible SOCKS server and client library for writing proxy-based applications. It supports SOCKS 4, SOCKS 5, authentication, CHAP, XML firewalling, Win32, server chaining, and UDP. It ALSO contains very experimental IPv6 support
介紹幾種cpuThe 8xC251SA/SB/SP/SQ improves on the MCS-51 architecture and peripheral features, introducing the advanced register based CPU architecture i.e., the MCS 251 microcontroller architecture. The register based CPU supports a 40-byte register file. In addition, the 8xC251SA/SB/SP/SQ microcontroller has 256-Kbyte expanded external code/data memory space and 64-Kbyte stack space. The new controller is ALSO specially designed to execute C code efficiently. More importantly, the 8xC251SA/SB/SP/SQ maintains binary code compatibility with MCS 51 microcontrollers but at the same time allows the use of the powerful MCS 251 microcontroller instruction set, with many new 8, 16 and 32 bit instructions available. The 8xC251SA/SB/SP/SQ has 512 bytes or 1 Kbyte of on-chip data RAM options and is available in 16 Kbytes and 8 Kbytes of on-chip ROM/OTPROM or ROMless options.
This a GA implementation using binary and real coded variables. Mixed variables can be used. Constraints can ALSO be handled. All constraints must be greater-than-equal-to type (g >= 0) and normalized (see the sample problem in prob1 in objective()).
Stantor is a Domotic project. It is a SCADA for the computer interface board K8055 (USB bus), K8000 (I2C bus) , X10 modules and ALSO Webcam. It uses Browser WEB, I-mode and Wap2/Wap1, Apache,mySQL, PHP, javascript. It run with Linux 2.4 or 2.6 and XP
gperiodic is a program for browsing the periodic table and looking up data for different elements. It ALSO features a non-graphical interface. gperiodicOrb是一個(gè)瀏覽元素周期表和查詢不同元素的數(shù)據(jù)的程序。它有一個(gè)非圖形化的界面。
