Graduation thesis summary

In March xx, I started my graduation thesis work. Today, the paper is basically completed. From the initial ignorance, to the slow entry into the state, and to the gradual clarity of the ideas, the entire writing process is difficult to express in words. After a few months of hard work, the intense and fulfilling graduation design finally came to an end. Looking back at the experiences and feelings of this day, I am filled with emotions. In the process of graduation design, I have countless unforgettable memories and harvests.

At the beginning of March, my topic was fixed in the discussion with the instructor. It is: 8031 ​​single-chip control LED display design. When the topic selection report and the opening report were finalized, I immediately started collecting data. At that time, I was a bit stunned by the vast sea of ​​books. I don’t know how to start. I told the instructor about this difficulty. Under the careful guidance of the instructor, I finally got to know the direction and method of my current work.

In the process of collecting information, I carefully prepared a notebook. I collect information in the school library, the work library, and also find all kinds of relevant information on the Internet. I will record all the valuable information in my notebook, and try to make my data complete, accurate and numerous. This is beneficial to the paper. write. Then I carefully sorted the collected data and gave it to the instructor for communication.

At the beginning of April, the information was already found, and I started writing the thesis. When I encounter difficulties in the writing process, I will contact the tutor in time and communicate with my classmates. I will ask a professional teacher. With the help of everyone, the difficulties are solved one by one, and the paper is slowly taking shape.

At the end of April, the narrative of the paper has been completed. In May, the drawing work and circuit design work of related graphics began. In order to draw a satisfactory circuit diagram, chart, etc., I carefully studied the drawing technique of Excel. In the early stage of designing the circuit, because there was no design experience, I felt that I couldn't get started. I had a lot of design ideas, but I didn't know which one to choose. After the guidance of the instructor, my design gradually got a clue. Through reviewing the data, I gradually established the system plan. In the scheme, the design of the LED display line and column drive circuit is a headache. In the process of re-evaluation and comparison, the row driver circuit is finally determined to use 74LS154 decoder, and the column driver circuit adopts 74HC595 integrated circuit.

When I finally finished all the tasks of typing, drawing, typesetting and proofreading, the whole person was very tired, but at the same time I looked at the graduation design manuscript on the computer screen. My heart was sweet, I think it was all worth it. The production process of this graduation thesis is a process of re-learning and improving. In the paper I have fully utilized what I have learned during college.

I will not forget this unforgettable few months. The production of graduation thesis gave me unforgettable memories. In the days when I searched for information in the sea of ​​books, in the face of countless books, the most memorable thing was the excitement and excitement every time I found the information. In the time of designing the circuit diagram, the deepest memory is the realization of every little thought. The happy mood at that time; for the essay I had rushed to the middle of the night, but looking at the words and words that I personally played, my heart was filled with joy and no exhaustion. This journey seems to be thorny, but there are endless treasures. I have mastered the knowledge of many single-chip microcomputers and LED display screens from the collection of data, so that I have consolidated and improved the knowledge I have learned, and let me know about the latest development technology of today's single-chip microcomputer and LED display. . Throughout the process, I learned new knowledge and gained insight. In the days to come, I will continue to enrich myself and strive to make a difference in my field of study.

Down-to-earth, serious and rigorous, realistic learning attitude, not afraid of difficulties, perseverance, hard work and hard work is my biggest gain in this design. I think this is a tempering of the will, an improvement of my actual ability, and will be of great help to my future study and work.

In this graduation design, our classmates have furthered the relationship. The students help each other. If you don’t understand anything, everyone will discuss it together. Listening to different opinions will help us better understand the knowledge, so I am very grateful for the help here. My classmate.

I would like to thank my tutors and professional teachers for their careful guidance and care so that I can successfully complete my thesis . In my research and the research work of the thesis, I have devoted my teachers to the hard work and hard work of the teachers. The teacher’s rigorous academic attitude, profound knowledge, and selfless dedication have inspired me. From the respected mentor, I not only learned solid and broad professional knowledge, but also learned the truth of being a man. I would like to extend my heartfelt thanks and deep respect to my mentor.
