application letter计算机应用技术范文Dear company leaders: shalom!Thank you for taking time out of your busy schedule to read my job search materials.I see the recruitment information of your company from the Internet, and I am very interested in the position of network maintenance engineer. My name is _, and I graduated from majoring in computer Science and Technology.With the respect and yearning for your company, I sincerely wrote this letter of recommendation, to show you a completely true me. The main courses include: computer network, operating system principle, computer interface technology, database system principle, data structure, algorithm and programming, C language, C + +, object-oriented programming, etc.During this period, I study hard, work hard work, and joined the Communist Party of China, become a Communist party member.As the secretary of the class youth league branch, I strive to do my own work well, the work has accumulated a lot of work experience, so that I have a good physical quality and psychological quality.In the past few years, I have worked hard to learn professional knowledge, starting from the basic knowledge of each course, trying to master its basic skills, deep drill and fine research, to seek its internal rules, and hasachieved good results.In my spare time, I also go to the library to serve the students. In the library, I have learned a lot of knowledge about all aspects of the network. I believe that the accumulation of quantity will inevitably lead to qualitative changes. Practice is the standard for testing the truth.So I attended the social training twice during the weekend and during the summer vacation of my junior year.The first training mainly studied CCNA and CCNP.Through the study of CCNA course, I have a certain understanding of network knowledge and master the basic operations of various protocols in the network, such as TCP / IP / I P, IGRP, OSPF, STP and other protocols.In the CCNP course, there are three main courses, routing, exchange, and misalignment.Routing has a more thorough understanding of the various protocols in CCNA, both in basic knowledge and hands-on operation, and has greatly improved the ability to solve various problems encountered in the experiment.After the training, the lecturer took us to a company for an internship. During this period, both our human communication skills and professional skills were greatly improved.The second training mainly learned the knowledge of network security and server building. Through this training, I have some understanding of the securityproblems in the network maintenance, and can solve some problems by myself.Although I have some inexperience now, I believe my expertise is enough to make up for it. In the sword sound, the sound of the period.I sincerely hope that I can share the destiny with you, share the development and seek progress.Please give me a chance, I will use action to prove themselves. Finally, I sincerely wish your company a prosperous and prosperous career. RGDS salute Job seekers: _ On _ , 20_尊敬的公司领导:您好!感谢您在百忙之中抽空阅读我的求职材料。

Abstract: this paper is the application of AT89S51 principle and control theory to music box hardware circuit design, and using C51 microcontroller programming language. Through controlling the microcontroller timer to generate the internal of different frequency square-wave, drive horn sends out the different music, tones of reusing delay to control the pronunciation time length. The program through my music into the corresponding timing constants to drive the pronunciation equipment play an euphonic beautiful music. This kind of control circuit of simple structure, high reliability and applicability is strong; Software programs adapt range, for different music only need to change the corresponding timing constants can. The SCM and music enthusiasts is of certain reference value.
关键词:AT89C51单片机 音乐盒 C51语言 Keywords: AT89C51 music box C51 language 一、 方案的设计与论证 First, the design with argument 1.方案设计 Scheme design. 1. 方案1: Plan 1: 用四个按键控制音乐的播放。3个按键选择3首不同的音乐播放,另一个按键控制音乐的停止。按下播放键,用一点简单的控制之后,才开始播放音乐。比如,用定时器控制,亮灯倒计时10秒然后触发音乐播放。
With four key control music playback. Three key choice 3 different songs music playback, another button control music stops. Press the play button, with a few simple control later, just start playing music. For instance, with lights countdown timer control, 10 seconds and then trigger music playback.
方案2: Plan 2: 用4*4小键盘来实现音乐的选择播放,1~A按键控制播放10首音乐,C~F按键分别实现欢迎页面、上一首、下一首、停止播放。
Use 4 * 4 small keyboards to achieve music selection playback, 1 ~ A button control play music, C ~ 10 tracks F buttons realized respectively welcome pages, on A, the following piece, stop playing.
方案3: Plan 3: 为了充分利用实验板的功能,进一步扩充音乐盒的功能。设计开机时用七段显示数码管LED显示英文欢迎提示字符HELLO,播放时显示歌曲序号。一个按键控制播放音乐,按下一次按键播放一首歌曲,另外三个按键分别实现上一首、下一首、暂停。考虑到实验的复杂度和时间上的局限,不再使用亮灯倒计时10秒才出发播放的构思。使用方案三。
In order to make full use of the function of experimental board, further expand the function of music box. Design is powered with seven segment display digital tube LED display English welcome hint characters, broadcasting displayed when songs HELLO serial number. A button control play music, press the next key play a song, another three buttons realized respectively on a poem, pause,. Considering the experimental complexity and time limit, no longer use bright lights countdown to 10 seconds to start broadcast conception. Use plan 3.
2.方案论证 2. Plan demonst 1) 在方案1中,共用了4个按键,其中3个按键控制播放3首音乐,另一个键控制音乐播放的停止。但是我们却只能选择3首音乐,局限性太强了。
1) on the plan 1, share four buttons, three of which button control broadcast three first music, another key control music broadcast stop. But we are only choose 3 first music, limitations is too strong.
2) 在方案2中,由于个人所学知识有限、实践经验太少等原因,我们仅实现了歌曲的播放、开机画面、停止,未能实现歌曲的上一首、下一首选择播放。由于 2) in solution 2, due to personal knowledge learnt limited, practical experience too little and other reasons, we can only achieve songs play, boot screen, stop, failed to achieve songs, a choice on a play. because
二、 单片机控制电路的设计 Second, a single chip microcomputer control circuit design 本设计中用到了89C51单片机,4*4键盘,蜂鸣器,16*2 LCD,七段显示数码管LED。 This design using the 89C51, 4 * 4 keyboard, buzzer, 16 * 2 LCD display, seven segment digital tube LED.
当键盘有键按下时,判断键值,启动计数器T0,产生一定频率的脉冲,驱动蜂鸣器,放出乐曲。同时启动定时器T1,显示乐曲播放的时间,并驱动LCD,显示歌曲号及播放时间。也可在LED显示歌曲号。
When the keyboard have keys when pressed, judge keys, start-up counter T0, produce a certain frequency pulse, drive the buzzer and released music. At the same time, show start timer T1 music broadcast time and drive LCD, display songs number and broadcast time. Also available in LED display songs number.
(1) 硬件电路中用P1.0~P1.7控制按键,其中P1.0~P1.3扫描行,P1.4~P1.7扫描列。 (1) hardware circuit with P1.0 ~ P1.7 control key, which P1.0 ~ P1.3 scan line, P1.4 ~ P1.7 scanning columns.
(2) 用P0.0~P0.7,P2.0~P2.7控制LED,其中P0.0~P0.7控制七段码a,b,c,d,e,f,g,用P2.0~P2.7为数码管位选信号。
