我所做的单片机串行通信发射机主要在实验室完成,参考有关的书籍和资料，个人完成电路的设计、焊接、检查、调试，再根据自己的硬件和通信协议用汇编语言编写发射和显示程序，然后加电调试，最终达到准确无误的发射和显示。在这过程中需要选择适当的元件，合理的电路图扎实的焊接技术，基本的故障排除和纠正能力，会使用基本的仪器对硬件进行调试，会熟练的运用汇编语言编写程序，会用相关的软件对自己的程序进行翻译，并烧进芯片中，要与对方接收机统一通信协议，要耐心的反复检查、修改和调试，直到达到预期目的。
Abstract:
With the rapid development of science and technology in recent years, the application of SCM is the deepening of the same time promote the traditional control detection technologies are increasingly updated. In real-time detection and automatic control of microcomputer application system, the microcontroller is often used as a core component to use only SCM knowledge is not enough, but also according to the specific hardware architecture hardware and software, to be improved.
Crossroads shuttle vehicles, pedestrians bustling Dealers lane, walkways, and orderly. Rely on to achieve this orderly order? Rely on automatic command system of traffic lights. Traffic signal control. The system uses the MSC-51 series of microcontrollers the ATSC51 and programmable parallel I/O interface chip 8255A-centric devices to design a traffic light controller, realized according to the actual traffic flow through the 8051 P1 outlet red, the green light to kindle the function traffic light cyc (2012-05-20, WORD, 265KB, 下载6次)
大型信息技术的软件包，如那些被称为企业资源计划（ERP），组织参与，具有重要意义，远远超出了公认的歌剧组织的问责性和综合效应跨职能和生产基地。我的主张是，作为一个程序的事，作为一个扩展的功能或跨职能交易系列组织呼吁人权机构的理解为前提的ERP软件包。相应地，大量引进ERP软件包组织势必会产生严重的影响，正是验票的程序及人的形式，通过这样的包组织仪器操作和时尚的组织角色。人权机构和组织的运作，在程序上的概念似乎是合理的，但它讲述一个非常具体的，在某种意义上说，人类和组织的了解有限。制定人权机构和组织在程序上的独特地位，成为显而易见的，在其与人类行为的其他形式，如即兴，勘探或玩并列。
In this article I argue that the organizational involvement of large scale information technology packages, such as those known as Enterprise Resource Planning (ERP), has important implications that go far beyond the acknowledged effects of keeping the organizational operations accountable and integrated across functions and production sites. My claim is that ERP packages are predicated upon an understanding of human agency as a procedural affair and of organizations as an extended series of functional or cross-functional transactions. Accordingly, the massive introduction of ERP packages to organizations is bound to have serious implications that precisely recount the procedural forms by which such packages instrument organizational operations and fashion organizational roles. The conception of human agency and organizational operations in procedural terms may seem reasonable yet it recounts a very specific and, in a sense, limited understanding of humans and organizations.

现代先进微处理器有非常高的集成度和复杂度，又有寄存器堆、Cache等嵌入式部件，而且芯片管脚数相对较少，必须要有一定的自测试设计和其它的可测试性设计来简化测试代码，提高故障覆盖率。本文简要讨论NRS4000微处理器芯片的以边界扫描测试为主体，以自测试为补充的可测试性设计框架。着重介绍芯片的边界扫描设计和芯片中译码控制器PLA和微程序ＲＯＭ以及采用内嵌RAM结构的指令Cache和寄存器堆的内建自测试设计。仿真结果表明，这些可测试性设计大大缩短了测试代码的长度。
modern microprocessors have a very high degree of integration and complexity, there Register pile, Cache such as embedded components, but Chip few relatively small, There must be the self-test design and testing of other design code to simplify testing, fault coverage. This paper briefly discussed Key words microprocessor chip to the boundary-scan test as the mainstay, Since the test to add to the test design framework. Highlighting the boundary-scan chip design and chip decoder PLA and micro-controller procedures and the use of embedded ROM RA M structure of the instruction cache and register stack of built-in self-test design. The simulation results show that these tests can greatly shorten the design of the test code length. (2006-11-12, WORD, 40KB, 下载118次)

推箱子，又称搬运工，是一个十分流行的单人智力游戏。玩家的任务是在一个仓库中操纵一个搬运工人，将N个相同的箱子推到N个相同的目的地。推箱子游戏出现在计算机中最早起源于1994年台湾省李果兆开发的仓库世家，又名仓库番，箱子只可以推, 不可以拉, 而且一次只能推动一个。它的规则如此简单，但是魅力却是无穷的。但是人毕竟思考的深度和速度有限，我们是否可以利用计算机帮助我们求解呢？
magazines, also known as porters, is one of the most popular single intellectual games. The task of players in a warehouse controlled a stevedore who will be the same as the N box pushed to the same N as a destination. PSP games on the computer which originated in 1994, the Taiwan Provincial Fruit Katherine Lee development of the warehouse family, also known as Fan warehouse, the boxes can only push, not pull, but one can only promote one. Its rules so simple, but the charm is boundless. But, after all, thought the depth and speed are limited, we can use computers to help us solve? (2005-04-26, WORD, 43KB, 下载37次)
