测试测量 智能照明控制器测量环境光线
Abstract: This application note explains how to design an intelligent lighting controller that senses and measures the ambient lightlevel with an ambient light sensor (ALS). Equipped with a real-time clock (RTC), the controller also knows when to turn lighting on oroff at specified times. The syst ...
测试测量 确定任务参数的温度记录仪
Logger iButton devices have gained a lot of popularity with researchers. Although free evaluation software is easy to use and welldocumented, the choices and inputs that need to be made can sometimes be challenging. This application note explains technicalterms that are common with temperature log ...
测试测量 DN427开关控制器故障保护电压监测
 
Have you had the exasperating experience of a laptop orPDA defi antly not responding to your commands? Youfrantically press key after key, but to no avail. As hopeturns to anger (but just before you throw the company’slaptop through the window) you slam your fi nger againstthe on/of ...
测试测量 基于Multisim 10的矩形波信号发生器仿真与实现
在Multisim 10软件环境下,设计一种由运算放大器构成的精确可控矩形波信号发生器,结合系统电路原理图重点阐述了各参数指标的实现与测试方法。通过改变RC电路的电容充、放电路径和时间常数实现了占空比和频率的调节,通过多路开关投入不同数值的电容实现了频段的调节,通过电压取样和同相放大电路实现了输出电压幅值的调节 ...
电子元器件应用 陶瓷电容器的温度和电压的变化
Abstract: The reality of modern, small form-factor ceramic capacitors is a good reminder to always readthe data sheet. This tutorial explains how ceramic capacitor type designations, such as X7R and Y5V,imply nothing about voltage coefficients. Engineers must check the data to know, really know, h ...
接口技术 谈集成电路的通用接口
Abstract: How can an interface change a happy face to a sad face? Engineers have happy faces when an interface works properly.Sad faces indicate failure somewhere. Because interfaces between microprocessors and ICs are simple—even easy—they are oftenignored until interface failure caus ...

数据库系统 Generating next numbers in SQLServer should not be a problem. But problems arise when a customer ask
Generating next numbers in SQLServer should not be a problem. But problems arise when a customer asks for different types of next numbers that you cannot generate directly from SQL Server. This brief article describes how you would tackle this problem in different scenarios.

This code will be useful to you if you have tried using ADOCE, but never got anything to work. It is not meant to be integrated into any application, but rather it should be used for demonstrative purposes. It clearly shows the basics of how to use the technology.
Windows Mobile Setting up an ADOCE project using Visual C++ 6.0 is rather simple. Assuming that you have downloaded
Setting up an ADOCE project using Visual C++ 6.0 is rather simple. Assuming that you have downloaded and installed the ADOCE SDK from Microsoft, you are ready to use it in your Windows CE Database applications. The sample that I have provided is a *very* simple one illustrating how to instantiate th ...
