CAN（Controller Area Network——控制器局域网）是一种由 CAN 控制器组成的高性能串行数据局域通信网络，是国际上应用最广泛的现场总线之一。它最早由德国 Bosch 公司于 1984 年推出，最初用于汽车内部测量与执行部件之间的数据通信。CAN-bus 总线模型符合 OSI 的 7 层结构；CAN-bus 规范已被 ISO 估计标准组织制定为国际标准。

Abstract: Many modern industrial, medical, and commercial applications require temperature measurements in the extended temperature rangewith accuracies of ±0.3°C or better, performed with reasonable cost and often with low power consumption. This article explains how platinumresistance temperature detectors (PRTDs) can perform measurements over wide temperature ranges of -200°C to +850°C, with absolute accuracyand repeatability better than ±0.3°C, when used with modern processors capable of resolving nonlinear mathematical equation quickly and costeffectively. This article is the second installment of a series on PRTDs. For the first installment, please read application note 4875, "High-Accuracy Temperature Measurements Call for Platinum Resistance Temperature Detectors (PRTDs) and Precision Delta-Sigma ADCs."

There are many manufacturers of dot matrix LCD modules. However, most of these displaysare similar. They all have on-board controllers and drivers capable of displaying alpha numericsand a wide variety of other symbols (including Japanese "Katakana" characters). The internaloperation of LCD controller devices is determined by signals sent from a central processing unit(in this case, a CoolRunner-II CPLD).

Displaying a large bitmap file on a dialog box, in its original size, is quite difficult in the VC++ environment. However, it is possible to display a large bitmap to a predefined area of the dialog by using the StretchBlt( ) function.The major disadvantage of this is that the clarity of the image will be lost. Check out this article for displaying large bitmaps into the desired area of your dialog box in its original size with a scrolling technique used to show the entire bitmap. 滚动显示位图 在VC++环境下，在一个对话框中显示一个原始尺寸的大小的位图文件相当是困难的。然而,通过使用 StretchBlt()函数一个给定的区域显示一个大的位图是可能的。主要的缺点是图像将会失真。看了这篇通过卷动技术显示整个位图技术的文章，你将能够以它的原始尺寸在给定对话框的区域内显示一个大位图。 来源: http://www.codeguru.com/bitmap/ScrollBitmap.html

一个简单的词法分析器，1代表字符，2代表关键字（命令字），4带表算符界符， 注：要把wangs.txt这个文件放在桌面上，然后在这个TXT里写上你要识别的语句。然后保存后关毕，在运行WANG词法分析.EXE进行词法分析。 完成识别后，会在相应的词面前出现以上代号。暂不能对数字进行识别。因为在某种请况下数字也可表是为字符……稍有困难，但完成老师的针对程序段：area=b+c*d。那简直是小菜一碟。

21天学会用JAVA开发网络游戏 书籍语言： 简体中文 书籍类型： 程序设计 授权方式： 免费软件 书籍大小： 287 KB 书籍等级： 整理时间： 2004-11-3 20:41:10 With all of the media attention that is focused on the Internet and the World Wide Web, figuring out exactly what they are all about is sometimes difficult. Are they just a neat new way to market products or will they truly offer us a new medium of communication that will someday surpass even televisions and telephones? The answer is, who knows? Unfortunately, the ultimate use for the Internet is still unknown. This is because it is still in such a state of flux that it s pretty much impossible to accurately predict where it will end up. However, you can look at the evidence of what is there now and gain some insight into what the Internet might become, at least in terms of games.

This book focuses primarily on XML itself. It covers the fundamental rules that all XML documents and authors must adhere to, whether a web designer uses SMIL to add animations to web pages or a C++ programmer uses SOAP to exchange serialized objects with a remote database. This book also covers generic supporting technologies that have been layered on top of XML and are used across a wide range of XML applications.
