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.

紅外在單片機上的應用,C語言源碼,Keil uVision3工程文件,附原理圖及說明學習文檔 紅外接收電路采用集成紅外接收器成品H1，接收器包括紅外接收管和信號處理IC，均集成在紅外接收器H1內。接收器對外只有3個引腳：Vcc、GND和一個脈沖信號輸出po。Vcc接系統的電源正極（+5V），GND接系統的地線，脈沖信號輸出接CPU的中斷輸入引腳INT0。如果沒有紅外遙控信號到來，接收器的輸出端口po保持高電平，當接收到紅外遙控信號時，接收器件信號轉換成脈沖序列加到CPU的中斷輸入引腳。CPU定時器T0、T1都初始化為定時器工作方式1，T0的GATE位置位，這樣T0只在INT0為高電平時計數。每次外部中斷首先停止定時，記錄T0、T1的計數值，然后將T0、T1的計數器清零，并重新啟動定時。T0的值即為高電平脈沖，T1－T0的值為低電平脈寬。 紅外發送電路是將單片機發送的信號（P2.7管腳），由一個38K的脈沖頻率進行調制，并通過一個紅外發射管發送出去。U11B和U11C及附加的電阻電容形成了一個38K脈沖發生器。
