Bochs is a highly portable open source IA-32 (x86) PC emulator written in C++, that runs on most popular platforms. It includes emulation of the Intel x86 CPU, common I/O devices, and a custom BIOS. Currently, Bochs can be compiled to emulate a 386, 486, Pentium, Pentium Pro or AMD64 CPU, including optional MMX, SSE, SSE2 and 3DNow! instructions. Bochs is capable of running most Operating Systems inside the emulation including Linux, DOS, Windows 95/98 and Windows NT/2000. Bochs was written by Kevin Lawton and is currently maintained by the Bochs project at "http://bochs.sourceforge.net".

This tutorial attempts to get you started developing with the Win32 API as quickly and clearly as possible. It is meant to be read as a whole, so please read it from beginning to end before asking questions... most of them will probably be answered. Each section builds on the sections before it. I have also added some solutions to common errors in Appendix A. If you ask me a question that is answered on this page, you will look very silly.

红外在单片机上的应用,C语言源码,Keil uVision3工程文件,附原理图及说明学习文档 红外接收电路采用集成红外接收器成品H1,接收器包括红外接收管和信号处理IC,均集成在红外接收器H1内。接收器对外只有3个引脚:Vcc、GND和一个脉冲信号输出po。Vcc接系统的电源正极(+5V),GND接系统的地线,脉冲信号输出接CPU的中断输入引脚INT0。如果没有红外遥控信号到来,接收器的输出端口po保持高电平,当接收到红外遥控信号时,接收器件信号转换成脉冲序列加到CPU的中断输入引脚。CPU定时器T0、T1都初始化为定时器工作方式1,T0的GATE位置位,这样T0只在INT0为高电平时计数。每次外部中断首先停止定时,记录T0、T1的计数值,然后将T0、T1的计数器清零,并重新启动定时。T0的值即为高电平脉冲,T1-T0的值为低电平脉宽。 红外发送电路是将单片机发送的信号(P2.7管脚),由一个38K的脉冲频率进行调制,并通过一个红外发射管发送出去。U11B和U11C及附加的电阻电容形成了一个38K脉冲发生器。
