基于LabVIEW和单片机的空调温度场测量系统的研究:室内温度是空调系统舒适性的重要指标,对其及时、准确地测量显得非常重要。介绍单片机AT89C51 和数字式、单总线型温度传感器DS18B20 组成矩形测量网络采集空调室内40 点温度,LabVIEW作为开发平台,二者之间通过串口实现数据通信,利用LabVIEW强大的数据处理和显示功能对采集的空调温度场数据进行实时处理、分析和显示,详细介绍了系统的硬件结构和软件模块的设计方案。关键词:单片机;DS18B20 ;LabVIEW;串行通信 Abstract : Temperature is a very important criterion of air condition system′s comfort , so it is very significant to measure it accurately and real timely. This paper int roduces a data acquisition system of measuring 40 point s temperature for air condition room based on single wire digital sensor DS18B20 and microcont roller AT89C51 which are composed of rectangle measuring meshwork. The data communication between LabVIEW and microcont roller is executed via serial port ,and the temperature field data of air condition room are processed analyzed and displayed on LabVIEW. The hardware and software modules are also given in detail.Keywords : single chip ;DS18B20 ;LabVIEW; serial communication

Abstract: Designers who must interface 1-Wire temperature sensors with Xilinx field-programmable gate arrays(FPGAs) can use this reference design to drive a DS28EA00 1-Wire slave device. The downloadable softwarementioned in this document can also be used as a starting point to connect other 1-Wire slave devices. The systemimplements a 1-Wire master connected to a UART and outputs temperature to a PC from the DS28EA00 temperaturesensor. In addition, high/low alarm outputs are displayed from the DS28EA00 PIO pins using LEDs.

This simple SDI Notepad-like application demonstrates how, taking advantage of the MFC support for Unicode, to Turkmenize labels of the specified menu items. Actually, Turkmen is not supported by Windows 2000, therefore, to create such resources as menu so that strings in Turkmen could be displayed I had to invent an additional technique 这是一个与记事本类似的简单的SDI应用程序，演示了怎样使用MFC来支持 Unicode，对指定的菜单条目进行Turkmenize标签化。实际上，Windwos 2000并不支持Turknen,因此,创建了那些菜单资源以便那些字符串可以在Turknen中显示,为此我必须开发其它的技术。 来源: http://www.codeguru.com/advancedui/SDI_Note.html

The code is fairly straightforward, except perhaps for the call to convertColumnIndexToModel. That call is necessary because if the user moves the columns around, the view s index for the column doesn t match the model s index for the column. For example, the user might drag the Vegetarian column (which the model considers to be at index 4) so it s displayed as the first column — at view index 0. Since prepareRenderer gives us the view index, we need to translate the view index to a model index so we can be sure we re dealing with the intended column

This build is for developing a "binary-to-BCD" converter for use in // displaying numerals in base-10 so that people can read and interpret the // numbers more readily than they could if the numbers were displayed in // binary or hexadecimal format. Also, a "BCD-to-binary" converter is // tested in this build.

This project attempts to implement a Database using B+Tree. The project has developed a DATABASE SYSTEM with lesser memory consumption. Its API includes simple SQL Statements and the output is displayed on the screen. Certain applications for which several features of existing databases like concurrency control, transaction management, security features are not enabled. B+Trees can be used as an index for factor access to the data. Help facility is provided to know the syntax of SQL Statements.

BmpRgn is a *FREEWARE* unit that allows you to create forms with transparent areas based on a bitmap that you provide. The bitmap is converted to a form region, where only the interior pixels are displayed. The transparent border remains transparent.
