he LPC932 can be used to create a Pulse Width Modulated PWM signal. That s an analog signal, with only 2 discrete levels, for example 0V and 5V and a constant period. The current value of this signal at a certain poiTnt of time is proportional to its Duty Cycle. That s the High Time during one period divided by the period. It can also be calculated as the average value during a particular period. That means after low pass filtering, (e.g. RC circuit) the signal becomes analog, with an actual value controlled by the microcontroller. The PWM functionality enables the LPC932 to control for example the speed of DC motors or the brightness of electric lighting.

众所周知,C++Builder本身并不提供串行通讯控件MSComm,但我们却可以通过注册后直接使用它。启动C++Builder5.0后,然后选择C++Builder主菜单中的Component菜单项,单击Import Active Control命令,弹出Import Active窗口,选择Microsoft Comm Control6.0,再选择Install按钮执行安装命令,系统将自动进行编译,编译完成后即完成MSComm控件在C++Builder中的注册,系统默认安装在控件板的Active页,接下来我们就可以像使用C++Builder本身提供的控件那样使用新注册的MSComm控件了。(前提条件是你的机子上安装了Visual Basic,或者有它的库)

abel Tool Sample Requires: Visual Basic 6 and MapObjects 2.x Data: redlands.shp (Redlands sample data set from MO 2.x) Interactive Labeling Tool If the check box is checked, then the mouse down location will search for the closest line, and label it with the street name. If the check box is not checked, then the mouse down will turn into a pan/zoom tool. There is a slider bar to control the search tolerance in screen pixels for the labeling.

应一些网友的要求,公布播放器的源码。其实最主要的原因是我懒得更新它了。如果你不能编译的话请在Import ActiveX Control中添加c:\winnt\system32\macromed\flash或c:\windows\system\macromed\flash中添加flash.ocx,然后install就可以了,如果您找不到flash.ocx那么请在添加/删除中加入marcomedia shockwave支持或安装flash6。还需要rxlib for d6控件。如果以上您正确安装了,那么就能编译它了。如果您改进了它或添加了什么功能请发我一份,谢谢! 我的信箱:mh_neil@163.com
