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.

一个单片机应用系统的硬件电路设计包含两部分内容：一是系统扩展，即单片机内部的功能单元，如ROM、RAM、I/O、定时器/计数器、中断系统等不能满足应用系统的要求时，必须在片外进行扩展，选择适当的芯片，设计相应的电路。二是系统的配置，即按照系统功能要求配置外围设备，如键盘、显示器、打印机、A/D、D/A转换器等，要设计合适的接口电路。

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.

用汇编语言实现RESET启动和热启动 程序名: RESET.ASM/BOOT.ASM 程序类别: 完整的汇编语言程序 功能: 用程序完成RESET启动和热启动 使用说明: 汇编连接以后转换为com文件运行 程序说明: 在日常用机过程中,如果出现了异常情况常常需要重新启动系统 .对于IBM PC 以及其兼容机,除了开机冷启动外,还有热启动和R ESET开关复位启动,他们的共同特点是转入BIOS的入口点(即ROM 的起始单元FFFF:0处),执行该处的跳转指令,转向启动程序,该启 动程序在执行过程中需检测复位标志字(在地址0040:0072处,占2 个字节)的值,若为1234则启动是不检测内存 若非1234则启动先检 测内存,再启动系统.热启动和RESET启动的不同之处在于热启动时 不检测内存,而RESET启动是需要检测内存.

C++读取Excel AppWizard uses "TODO:" to indicate parts of the source code you should add to or customize. If 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.
