扫雷程序的需求分析，可以根据此分析来做一个跟微软一摸一样的程序。-De-mining process needs analysis, based on this analysis can be done with a program like Microsoft.

LWIP是TCP/IP协议栈的一种实现。LWIP的主要目的是减少存储器利用量和代码尺寸，使LWIP适合应用于小的、资源有限的处理器如嵌入式系统。为了减少处理器和存储器要求，lwIP可以通过不需任何数据拷贝的API进行裁减。 本文叙述了lwIP的设计与实现。叙述了协议实现及子系统中所使用的算法和数据结构如存储和缓冲管理系统。还包括LWIP API的参考手册和使用LWIP 的一些代码例子。-LwIP is TCP/IP protocol stack as a realization. LwIP main purpose is to reduce the memory utilization and code size, so lwIP suitable for small, resource-limited processor such as embedded systems. In order to reduce the processor and memory requirements, lwIP can copy any data without the process of reducing the API. This paper describes the Design and Implementation of lwIP. Describes the protocol and subsystems used in the algorithms and data structures such as storage and buffer management system. LWIP API also includes a reference manual and use lwIP some code examples.

欢迎使用“PLC串口通信调试” 本软件主要用于PLC(或单片机)与计算机的串口通信调试。软件根据目前PLC常用的多种串行通信协议的特点设计，数据的输入、组织和显示方式灵活多样，便于使用和观察调试。 在编制计算机与PLC的串口通信程序时，由于计算机和可编程设备双方均需编制通信程序，调试时往往不知道是哪一方的程序出了问题。可以使用本软件调试PLC一侧的程序，调试正确后再调试计算机侧的程序。本软件为PLC串口通信程序的调试提供了便利。-Welcome to "PLC serial communications debugging" This software mainly used for PLC (or single-chip) and the computer s serial communication debugging. According to the current PLC software for a variety of common characteristics of serial communication protocol design, data input, organize, and display flexible, easy-to-use debugging and observation. In the preparation of the computer s serial communication with the PLC program, computers and programmable devices as a result of both procedures require the preparation of communication, debugging often do not know which side the procedure is a problem. Can use the software side of the PLC program debugging, testing the right side after the debugging of computer procedures. The software for the PLC seria

此代码为液晶屏与接口提供很好的例子，此代码为特定类型的微控制器不写的是有用的用于任何芯片上。代码包含各种类型的功能，如液晶、 写数字和等写作字符串和指令。头文件可以根据特定的控制器改变了，不能限制。重要说明要提是编写此代码是以 4 位模式液晶屏与沟通，在此方式 fewe 引脚的微控制器将使用，会留给其他设备。
