单片机综合实验报告之模拟交通灯设计.doc

leading cadres ' awareness of right in place, study the party Constitution and party rules, series of speeches can make proper effect. Party cadres to "two" lead by example, to lead by example we must change our mind, recognizing that "two" is important. First, learn the Communist Party Constitution Party rules, learning learning series important speech by General Secretary can enhance theory. With the "third revolution" the rise of rapid changes in our life are feeling, the Communists should adhere to the theory of confidence will continue to learn from the voices of the times, the times, in turn, will have new requirements for leading party cadres. "Two" is the most basic meaning of members all mastering the core theory and the most advanced weapons theory, complement the spirit of calcium. Secondly, the Communist Party Constitution Party rules, learning learning series important speech by General Secretary be able to firmly build the ideological foundation. Under the impact of multiple values, the "two" is to help cultivate independent judgment in numerous miscellaneous multiple concepts, so that the majority consensus of party members, the important magic weapon of the party with the resonance frequency. Finally, the Constitution of the Communist Party, party rules, learning learning series important speech can stand crowds, General Secretary position. Now, some grass-roots work in the "the old way didn't work, hard way cannot, the new approach would not" phenomenon, sometimes due to a mass of party members and cadres not understanding, does not meet. In fact, the mass "convincing" and "identity"Behind are likely to be party members and leading cadres themselves ignoring beliefs held, resulting in lack of persuasion and sense of identity. "Two" is in fact guaranteed party cadres work, an important prerequisite for convincing the masses. Bacon said it well: "practical men can handle individual matters, but looking at the whole operation globally, but only man can do to knowledge. "Giving up" two "effective, must first raise awareness of leading cadres of party members, as party members learn real responsibility" to know "to" music "," good "changes, in parallel with the ground, do not forget to also answer the antenna, draw catches on meteorology, which sit between heaven and Earth which melds together the dreams of practicing Communist. Members cadres should in "two learn a do" in the based post do contribution in all members in the carried out "learn Constitution Party rules, and learn series speech, do qualified members" learning education, this is following party of mass line education practice activities and "three strict three real" topic education zhihou, deepening party education of and once important practice, is promoted "three strict three real" topic education from "key minority" to all members expand, and from concentrated education to regular education extends of important initiatives. 　　 Vast numbers of party members and cadres in the course of two, should be

一、实验内容：
用8255芯片的PA、PB口低四位做输出口，控制十二个发光二极管燃灭，模拟十字路口交通灯管理，并利用数码显示器进行倒计时显示（采用单片机内部定时器定时）。通过外部中断能使交通灯暂停运行，并点亮4个红灯。通过16*16点阵中的图形模拟控制行人过马路的人形“走”、“停”指示灯，可参考下图所示：

利用实验系统16×16点阵实验单元，以两种方式控制点阵显示。要求编制程序实现汉字点阵循环显示。
I/O口地址分配
I/O口分别提供字形代码（列码）、扫描信号（行码），凡字形代码位为“1”、行扫描信号为“1”点亮该点，否则熄灭；通过逐行扫描循环点亮字形或曲线。

二、实验电路及功能说明

三、实验程序流程图：

四、实验结果分析
通过程序仿真，可以检测设计的电路能基本满足设计要求。
交通灯亮灭过程同“8255控制交通灯实验”，倒计时显示只需两位数（0～99），用定时器定时进行倒计时，每秒钟减1。在16*16点阵中显示的人形“走”、“停”标志可自定义。
五、心得体会
我们通过作这个单片机实验，我们总结了一下点：
1、 加深了对51单片机的理解，不仅仅是以前那样只能点亮发光二极管。
2、 感受到了完成一件程序的乐趣，并且知道了实践精神。
3、 理解了51单片机的强大和我们知识的肤浅。
4、 学到了许多原来C语言中没有的东西，如：控制按键的程序
While(P0_5==1)
{
Time++;
While(P0_5==1);
}
这样可以不加防按键抖动的延时程序，更精确时间。
5、进一步充分利用中断时刻都在运行，让时间在中断中显示，就不会出现进入死循环后而无法显示时间的情况，而且还可以快速的反映除时间的变化。

非谓语动词是历年高考英语的重要考点之一，也是较难掌握的难点之一。它贯穿于英语学习和考试过程的始终。但是，只要认真分析、透彻理解、看透本质、准确把握，就一定能在高考中运筹帷幄，游刃有余。based on their actual, striving to be "learning" and "done" markers. Strengthening theoretical study, belief and faith. Theory is an action guide, only theoretical knowledge in place, to unity, action can consciously. Constitution is the fundamental law of the party, party rules are party must follow the General rules. Studying and implementing the party Constitution Party rules and a series of important speech, General Secretary, is a guide to persisting and developing socialism with Chinese characteristics, is a basic work of strengthening the party's construction, but also each and every Communist Party Member's obligations and solemn responsibility. These important content, for each party, must know would believe will do both. WeGeneral Secretary of the party Constitution, a series of remarks with, and hold, grasp the real "learning" that basis, based on the Constitution speak to issue, in accordance with the series changed the problem. Second, disciplined in line, to become law-abiding model. Is not no rules If there is no iron discipline, party members and cadres will become a mess, it will lose its fighting strength and vitality, purity and naturally much less advanced. 　　 By "two" education, party members and cadres to keep the "bottom line", not the more "red lines", consciously practice the "three Suns" and consciously act according to the Constitution, party rules, remains a political force, to perform party oath, a tree of its own image. Three is the loyal, dare to play and play to party members. Learning is the Foundation, is the key to development is the goal. "Two" main objective is to let the majority of the play to the exemplary role of party members and cadres, party Constitution, party rules to examine. To use new criteria to guide our behavior. Through education, the ideal and conviction, keep in mind that membership, learn, learn, learn go play a vanguard and exemplary role the courage to play as, and always maintain the pioneer, pioneering and enterprising spirit, and constantly improve our own capacity and level of service, according to positions and make contributions. Hearts change, lead more strict "began in the know, know as Luke Skywalker", "two" activities, be qualified party members both a starting point and ending point. 　　 Party cadres only opinions, Foundation, Constitution Party rules, series to better address outside in shape, "two" this is State, leading by example, to lead by example to be qualified party members in the process of doing the deep and solid, higher and more stringent. Jobs with new skills. To be a qualified party member, most basic element is always advanced requirements themselves, using their power to push forward the cause of the party, the people and the nation. Is to the leading cadres of party members, first of all is based on the job, do the people in the heart. There is not a slogan, but aims to better serve the people, targeted efforts to increase the capacity
