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.

This book isn t for uber-programmers who already have all the answers. If you think that J2EE does everything that you need it to do and you can make it sing, this book is not for you. Believe me, there are already enough books out there for you.

要如何区别呢？执行公用程式‘file’（例如，file /bin/bash）就对了。就ELF的程式而言，萤幕上显示出来的讯息会含有ELF的字眼；如果说是a.out的，讯息内会箝有 Linux/i386的字样。

它是VC++6.0下面的一个项目，该目录包括PL/0编译器的源代码。 PL0/debug下面是已经编译成功的PL/0编译器:PL0.exe。该小编译器可以处理一些简单的 利用PL/0语言书写的程序。例如，PL0/debug下面的test.PL0就是一个简单的 PL/0 程序。 运行PL0.exe, 并把test.pl0提供给PL0.exe,处理结果将保存在test.out 中。 注：test.pl0 和 test.out 可以用Notepad(记事本)软件打开。
