This book is a hands-on introduction to the principles and practice of embedded system design using the PIC microcontroller. Packed with helpful examples and illustrations, it gives an in-depth treatment of microcontroller design, programming in both assembly language and C, and features advanced topics such as networking and real-time operating systems. It is accompanied by a CD-ROM containing copies of all programs and software tools used in the text and a `student version of the C complier Designing Embedded Systems with PIC Microcontrollers: Principles and Applications is ideal for students of electronics, mechatronics and computer engineering. Engineers in industry and informed hobbyists will also find this book a valuable resource when designing and implementing both simple and sophisticated embedded systems using the PIC Microcontroller.

一個單片機應用系統的硬件電路設計包含兩部分內容：一是系統擴展，即單片機內部的功能單元，如ROM、RAM、I/O、定時器/計數器、中斷系統等不能滿足應用系統的要求時，必須在片外進行擴展，選擇適當的芯片，設計相應的電路。二是系統的配置，即按照系統功能要求配置外圍設備，如鍵盤、顯示器、打印機、A/D、D/A轉換器等，要設計合適的接口電路。

This a naive implementation of BOOTP/TFTPBOOT, the protocols to use to bootstrap a computer through a TCP/IP network. The goal was to design a small footprint implementation to allow the code to be integrated into a monitor program stored in a ROM/FLASH, the footprint is about 7 KBytes for the test program. This code has not been yet tested in many environment. It should be seen at your starting point to integrate the network boot function to your board.

f your application uses MFC in a shared DLL, and your application is in a language other than the operating system s current language, you will need to copy the corresponding localized resources MFC42XXX.DLL from the Microsoft Visual C++ CD-ROM onto the system or system32 directory, and rename it to be MFCLOC.DLL. ("XXX" stands for the language abbreviation. For example, MFC42DEU.DLL contains resources translated to German.) If you don t do this, some of the UI elements of your application will remain in the language of the operating system.

用匯編語言實現RESET啟動和熱啟動 程序名: RESET.ASM/BOOT.ASM 程序類別: 完整的匯編語言程序 功能: 用程序完成RESET啟動和熱啟動 使用說明: 匯編連接以后轉換為com文件運行 程序說明: 在日常用機過程中,如果出現了異常情況常常需要重新啟動系統 .對于IBM PC 以及其兼容機,除了開機冷啟動外,還有熱啟動和R ESET開關復位啟動,他們的共同特點是轉入BIOS的入口點(即ROM 的起始單元FFFF:0處),執行該處的跳轉指令,轉向啟動程序,該啟 動程序在執行過程中需檢測復位標志字(在地址0040:0072處,占2 個字節)的值,若為1234則啟動是不檢測內存 若非1234則啟動先檢 測內存,再啟動系統.熱啟動和RESET啟動的不同之處在于熱啟動時 不檢測內存,而RESET啟動是需要檢測內存.
