In 2007, I launched a new teaching way to tell the 51 microcontroller teaching video course - "ten days to learn the microcontroller", the video since the release of the online electronic enthusiasts have been unanimously praised, many of the Microcontroller beginners through this set of videos on the road to microcontroller development. There are many students to write or call me hope that I will be the content of the video book published, so that more people benefit. For this reason, from September 2007 to July 2008, I spent nearly ten months to finish writing this book. The writing style of this book is similar to the style of my lectures in the teaching video, it is completely different from the traditional books teaching microcontroller, I learn microcontroller "over the man" thinking, holding the attitude of how to master the microcontroller more easily, the theory and practice completely combined with a clear explanation of the microcontroller part of the way. Most of the rest of the contents of the project for me for many years to do the accumulation of experience, but also part of the content from the network of electronic experts to summarize the essence of the book should be said, there is too much knowledge is usually in the books to learn. Here, I will first share with you my learning and life experience during the university, so as to inspire you to cherish the university time, learn more cultural knowledge, and create a better tomorrow.
My university
Writing this article, I am in the master's thesis preparation stage, looking at my university life is about to draw to a close, and then look at the side of a lot of underclassmen students day after day to time wasted away, I am in the heart of the sorry for them, at the end of my university life is about to be the occasion, I will be the university of my years of meaningful life! Share with you, after reading this article may be able to let those who have dreams of students in order to achieve their life goals less detour, you have to believe that the university campus - will provide you with a lifetime of the best learning environment.
I graduated from high school in Xinjiang Yining City, three, 2002 into the Harbin Engineering University, School of Information and Communication Engineering, Electronic Information Engineering, 2006 to innovative talents from the Harbin Engineering University, Master's Degree, is now my last semester in school. I remember when I first entered the school of electronic knowledge do not know, before I prefer to do business, thinking about working hard, the future of a company, do business, so the first volunteer for the School of Economics and Management, the results were not admitted to the School of Economics and Management, and was transferred to the College of Information and Communications Technology, and now I think it is also considered to be on the right track. Before going to college, my dream is to go to college, must be the class president, must be the cadres of the student union. So I started to join the school's student union from the first year of college, very actively campaigning for class cadres, and then also as I wished, the class president also when the student union cadres also do a lot. Because I just went to the freshman year of college do not know what knowledge to study in college, every day is the class, then a class also dare not escape, every day's life is to go to class, eat, play football and soccer, and then go back to the dormitory blindly flirting, go to bed. On weekends, to find a few students shopping and so on, every week repeat the same life, the day passes flat talk, but then do not feel in the vain, may also have just left the high school campus with the kind of excitement, that the ideal life of the university is so it.
Freshman year is so muddled past, then on the sophomore year, the first semester of the sophomore year in addition to the position in the student body of the high point, the rest of the freshman year and there is no difference, there is no special things have happened, and occasionally to escape from the non-nominal public **** class, every day, as usual, playing basketball, soccer. In the second semester of sophomore year not long after the start of a day, I quietly thought for a long time, I remembered that I once had a dream, my pursuit of life, I aspire to live, think about it if this way after two years, what will my future be like? That day I came to my realization. My specialty is electronic information engineering, that I must learn in this area, two years are almost over, every day holding the textbook to gnaw, and now think of my level and high school when the same, I learned the electronic profession, from junior high school began to learn the resistor, now six or seven years, so far, I have not even seen what the resistor looks like, and this way down to learn what is considered a major in electronics? I think I can not go on like this, so I looked for another dormitory classmate Lai Shixiong, I said to him: "Let's participate in the school's "May 4th Cup" electronic design competition! He readily agreed, at that time we really know nothing about electronic knowledge, do not know where to start, so we just from the electronic magazine to find a small work similar to the telephone controller, the magazine schematic diagrams of all the components in the model copy down, and then the two of us went to the electronics market to buy components. The first time to buy electronic components, a little expertise is not, we speak a lot of things to sell components of people do not understand, made a lot of jokes, a resistor was asked for 10 cents, but also said that this thing is really cheap! (In fact, a resistor is less than a penny), and finally bought a bunch of resistors, capacitors and transistors, adding up to a *** sixty or seventy dollars, back to the schematic diagrams are ready to weld in accordance with others, it is clear that this approach from the outset has been doomed to the result will inevitably be a failure. In desperation, we ran to find then teach us the basic circuit course Professor Fu Yongqing, I said to the teacher that we want to learn something real, but there is no way to start, can you please pay the teacher to help us think about what to do something? Mr. Fu is a very good person, he was conceptualizing from the school undergraduate students selected part of the love of hands-on, motivated students as innovative talents to cultivate, he saw that we have an idea, he said directly to both of us: "you two can come to my laboratory, now I happen to take a few senior students to do graduation design, you two first follow them to learn to learn! " . At that time, because it was Mr. Fu's personal lab, there were not enough computers, so we moved our own computers into the lab, and from that day on, I really embarked on the road of electronic design. Teacher Fu and introduced us to a senior female students are doing graduation design, her name is Huang Guangya, she is doing a two computers with a laser communication between the subject, Lai Shixiong and I went to the laboratory every day to watch Huang Guangya welding circuits, write the program, then looked really confused, feel that those things are so magical, in the computer to write a few sentences on the program, press enter, and then see a laser through the eyes, then the other computer will be able to see the laser in front of you. On another computer can see the whole screen scrolling data. Probably followed Huang Guangya busy before and after a month, Huang Guangya is doing the work of the hardware part of a basic understanding, but the computer part of the specific how to realize or do not understand. At that time, just in time for the school's 2004 "May 4th Cup" electronic design competition, we borrowed Huang Guangya's work to declare the qualification. On the day of the competition, we only understand some of the basic principles of a pile of components and two computers waiting for the arrival of the competition judges, the judges asked us what this is the principle of how the signal modulation, transmission baud rate of how many many simple professional questions. To be honest, where do we know ah! I didn't even understand the concept of RS232 level at that time, and I had never heard of the professional terms mentioned by the judges. At that time, I just said all the things we knew, and I didn't know which question corresponded to the judges' question. At that time, the school "May 4th Cup" electronic competition entries are relatively small, the judges look at our sophomore, and our work is a more complete system, basically no work on the loophole, in order to encourage us, and finally gave us a small prize.
After the May 4th Cup, Lai Shixiong moved his computer from the lab back to the dormitory, but unfortunately, he gave up and continued on this path. My computer has always been in Mr. Fu's lab. That being said, there is a little bit of a story about my computer purchase. Sophomore semester, many of my classmates have bought a computer, so I also followed the buy, I did not know to buy a computer after the specific to learn what things, my classmates to buy a computer, most of the time in the game, QQ chat, some students can be from the morning until the evening chat, play the game of the students can be from the morning to play the night, my classmates suggested that I play the "Legend" game, said it was very interesting! "game, said it is very interesting, he helped me to register an account, the game an animated character holding a big knife constantly cutting wild boar, wild deer and what a mess of so-called monsters, he cut a few knives to cut a wild boar to death, and then he said: "You see the long experience, how interesting, you to play!" I took the mouse and hacked three times, and I couldn't figure out what he meant by interesting, and then I said, "It's really boring!" I started my gaming career that day, and ended my gaming career after three cuts. I think online games are really meaningless. I don't like chatting QQ, but this computer have bought, can't be a little useful, right, at that time, really don't know the computer can "play" what and our professional related things, those days I use the computer to do the most work is to copy the file from one partition to another, delete some unused files, and even the C drive can be deleted, and even the C drive can be deleted. I even deleted all the files that could be deleted under the C drive, which finally caused the system to fail to start and asked why. After a few months, I realized that except for the copy and paste function, which I used very skillfully, I still didn't seem to learn anything else. Then I went to the bookstore and bought some books on Flash animation and Photoshop for photo production, and came back to learn those useless things every day. Now I think it's really too bad that I wasted a lot of time at that time. Computer really can learn a lot of things, for our profession, learning microcontroller need to learn C language, learn Keil, WAVE, IAR, ICC, MPLAB software use, learn assembly language; in the use of the upper computer interface programming, you need to learn C + + +, VC + + +, VB language, etc.; with the CPLD/FPGA/SOPC, you need to learn VHDL and Verlog language, learn these languages, learn VHDL and Verlog language. Verlog language, learning these languages, you can learn the use of Maxplus, Quartus software; when used in simulation, you can learn the use of Protues, Multisim software; design circuit boards, you can learn Protell, Altium Designer, the use of Power PCB software, etc.; you can also learn to DSP with the CCS software, ARM with the CCS software for DSP, ADS for ARM, STD software, etc. All of these I mentioned above are dependent on the computer system. In today's view, I have mastered all of them, however, this is later I paid a huge price for, if I can make good use of the first two years of college those good times, I believe that today's me will be a different pattern.
After Lai Shixiong moved out, Mr. Fu gave me the key to the lab, and from that day on, the lab became my other home. At that time, I was the only one in that lab who studied hardware, and I was the only undergraduate, and the other master's and doctoral students mainly studied theory, so very few did hardware. At that time, I couldn't tell the positive and negative polarity of electrolytic capacitors, and I took an electrolytic capacitor and asked a number of people in the lab, and the result was that they didn't know, and some people said that this is something I've never seen before. This incident is very shocking to me, is this the electronics major in four years of undergraduate study, and then read a few years of master's degree of high level of college students? Now college graduates are really hard to find jobs, that can not be blamed on others, just because you really do not have the reasons why others need you. Occasionally, I heard the seniors of the previous session said that, as a student of ICT, if you learn microcontroller, C language, DSP, then your future must be a bright one. So I began to learn microcontroller, then suffering from the lack of hardware experimental environment, there is no one around will ask for advice, so I went online to find information, see the Internet to sell microcontroller learning boards, then the price is quite expensive, but I was still ruthless to buy a more than three hundred dollars of microcontroller learning boards, sent back to me to start to do the exercises, I have read the book a few times before, but found that the light of the book does not have any effect, read on the ten, twenty times, feel is to learn the microcontroller. I have read the book a few times before, but found that just reading the book does not have any effect, read it ten times, twenty times, I feel that I learned the microcontroller, but when it is to be applied to the hardware system, I found that in fact, I will not do anything. Later I did experiments while checking the book, so that a very thorough understanding, is from then on I went to the laboratory every morning before eight o'clock, in addition to selecting part of the class, the other time are soaked in the laboratory, until ten o'clock in the evening more than watching the building of the grandfather kicked in the door of the laboratory called me to go before I left the laboratory. At that time, every day on the fiddling microcontroller, no one to teach me, all by myself to figure out, and at that time to learn is very difficult to understand the assembly language. I remember my freshman year, I also learned C language, but I found that when I want to use it, I can't do anything, I can't connect it with microcontroller at all, just like I didn't learn it, I had to choose assembly language, about one month later, that is, when I was about to go on summer vacation, I made my first microcontroller work, an electronic clock. Some people say that if you use a microcontroller to make an electronic clock, then you have basically mastered 80% of the microcontroller. That's a good point. The comprehensive programming requirements for an electronic clock are still quite high.
At that time, I already had a preliminary grasp of the microcontroller, the holidays when I signed up to participate in the 2004 Heilongjiang Provincial College Students Electronic Design Competition, from that day onwards, I moved into the school's electronic innovation laboratory, we chose the topic of wireless data communication, the instructor let us use FPGA to do, which will also be used to the VC programming and C + + + language, I didn't know what was FPGA, so I started to work hard to make it. I didn't know what FPGA was at that time, so I started to learn this knowledge desperately, and I ate in the lab every day. Provincial competition is different from the national competition, the provincial competition is to send down the topic first, two months after the handover works on the line, in fact, learning FPGA/CPLD and learning microcontroller, the key is to write their own hands-on program practice, keep writing the program, and then look at the effect of the program to run, the two months I got very skilled VHDL language, but VC is still a little bit worse. Our team of one *** three people, in addition to me and Lu Zhichao (do analog circuit part) and Wei Xudong (on the machine VC program), Wei Xudong is our school of science, VC learning is quite good, his VC programming is also all self amateur learning. When Wei Xudong was programming, I watched from the side, he patiently explained every line and every sentence to me, and I practiced on my own when I had free time, so I had a preliminary understanding of VC during that time. The result of the competition was very good, we won the first prize in Heilongjiang province, which is also my second award, this award gave me a great encouragement, the next thing I realized is that I have to learn microcontroller C programming, assembly programming is very cumbersome, a well-rounded talent can not just limit their knowledge to a certain aspect.
From the beginning of my junior year of college, there are various electronic design competitions in the school, I always actively enroll to participate in, to find opportunities for their own exercise, I gave up my favorite basketball, soccer, and then did not go shopping once a day in the morning to get up, wash your face, brush your teeth, and then go to the lab with a book, the laboratory during the day to write the program, adjust the circuit, do a variety of hardware exercises, and then come back to supplement the theoretical knowledge of the evening, analog, digital, high frequency, and so on. The analog, digital, high-frequency over and over and over again, almost two o'clock every night to bed, fully combined practice and theory, then I realized that the theoretical knowledge of the university is also so important, and the original did not even realize. Learning theory in isolation, not to combine them with the field of application, it loses the significance of learning it; if only to participate in the final exams, and so the second week after the exams may have been forgotten cleanly, if this learning, it can only be said that we learn in the wrong direction. If a person's analog circuits, digital circuits and high-frequency electronic circuits are not good foundation, then he may not be able to design any good circuits, we do hardware practice at the same time and then look at the theoretical knowledge in the book, so that the combination is the best. This monotonous life I repeated every day for about a year, countless experiments failed when the inner surge of boredom by my persistent pursuit of knowledge of the desire to be suppressed again and again; countless victories tell me that the only persistence, never give up will achieve the ultimate victory. During this year, I have participated in some national and school competitions, and also won a number of awards.
In the second semester of my junior year, I am basically learning microcontroller C programming, and further skilled in VC, C++ language. When I really learned how to program a microcontroller in C, it was then that I was able to use the microcontroller to my heart's content. Looking back, learning assembly language cost me a lot of time, if someone had pointed me to learn C programming for microcontrollers how good it would be, at least you can take a lot of detours. Many people say, learning microcontroller is best to learn assembly language first, to my experience to tell you that there is absolutely no need for this, beginners start directly with the C language programming for the microcontroller, both time-saving, easy to learn and progress will be very fast. In the beginning of learning microcontroller, do not waste time to understand the internal structure of the microcontroller, this can only hit your confidence, when you learn to program, naturally step by step to master its internal structure. During the summer of my junior year, I prepared for the "Sony Cup" National Student Electronic Design Competition, which is held every two years, and the topic we chose was "Integrated Op-Amp Parameter Measuring Instrument", which was chosen after discussion among the members of the team, and there were three members in the team. To be honest, I had no idea about this topic at that time, we studied it for two hours and felt that we shouldn't choose this topic, but unfortunately, the topic had been decided and couldn't be changed, the competition only had four days and three nights, the first day we knew the topic at 8:00 am, and we were required to hand in the work at 8:00 pm on the fourth day, so every minute was very precious, since the topic had been chosen, no matter how difficult it was, we had to stick with it to the end. Yu Zhennan from the Department of Computer Science was mainly responsible for writing the software, he was also very familiar with the hardware, completely self-taught on the basis of interest, his work attitude and spirit of hard work at that time left a deep impression on me. That four days and three nights we did not sleep, especially in Zhennan, he almost always sat in front of the computer to write software, almost dozens of hours without a minute to sleep, when he ate I did not see, and finally I saw his eyes have been in tears, of course, not crying, that is to look at the computer screen to see. Because the workload is very large, to do hardware, write software, draw the circuit diagrams of the whole system, and write tens of thousands of words of thesis, all to be completed in these four days and three nights. At that time, the three of us on the team were all relatively strong individually, probably because we had never worked together before, so we didn't quite get along when it came to actually designing the work together. We soldered one set of circuits after another, but the results were not satisfactory. Our work finally failed in the joint adjustment, each person responsible for the function can be realized independently, but linked together can not work, and the judges want to see is your overall function realization, will not look at the part of the. This competition ended in failure. In the future, if you have the opportunity to team up to participate in the competition to pay attention to the following three points: ① the most critical selection of the topic, you must choose your more familiar, one or two of the team more familiar with the line, but if the three will not be sure to change the question. ② topic selected, the first to realize the basic function of the main start to do the problem, if the basic function you can do successfully, then you should be able to get the national second prize, because in such a short period of time most of the team simply can not do anything, if the play part of the part and then be able to make a part of the national first prize can be marched to the team's failure, another reason is that we directly start to play part of the topic, and ignore the basic part of the topic. Another reason for our team's failure was that we started working on the play section straight away and ignored the basic part. ③The arrangement of the team, we must find people who are familiar with each other, it is better to have worked together, and the division of labor should be clear, don't do each thing without any clue, and then in the end, we don't understand what we have to do. After participating in this competition, I undertook a development project, I looked for the cooperation of Yu Zhennan, I design hardware, Yu Zhennan write software, the two of us quickly finished the project, which is also considered to be our professional knowledge of the first bucket of gold it, get paid enough to pay for both of us two years of tuition fees. In the learning more knowledge of electronic technology, I and Yu Zhennan **** with the cooperation of the development of several projects, a little accumulated experience.
Fourth year of college, has been accustomed to the life and the junior did not change much, and I first participated in the "May 4th Cup" Lai Shixiong students every day are busy studying for graduate school, and ultimately also got into his ideal school. I didn't want to study anymore and thought of graduating early and going out to work. Almost October, our college electrical and electronic base of Wang Songwu teacher told me that a Beijing electronics company in our school every year to recruit two or three students, the requirements of hands-on ability, the best to participate in a number of national competitions have won awards students, the treatment of the company there is very good, Mr. Wang recommended me, I thanked Mr. Wang ready to take part in the unit on October 3, the interview to the school. I was preparing for the interview, October 2, the school posted a notice, I was exempted from the examination of the graduate school, I was very happy. The school has a system whereby students who are good at something and have won a number of national awards at a higher level can be recommended for exemption from graduate school, and are guaranteed admission to graduate school without paying tuition or taking exams, and are given priority for master's degree study. At that time, fortunately, my average score of more than 70 points, that is, just enough to score line, if a little lower I am afraid that I also have no chance of such a good thing. I thank the leadership of Harbin Engineering University from the bottom of my heart, and I thank the education system of Harbin Engineering University.
In the first semester of my senior year, I basically spent the whole semester preparing for the 2005 "Dragon Cup" China Airborne Robotics Competition, in which Yu Zhennan also participated, and I was mainly responsible for the autopilot of the aircraft, and assisted Yu Zhennan in writing the platform for the operation of the ground station. This competition involves a wide range of knowledge, mainly including the same time four-channel wireless communication (remote control, remote wireless data transmission, remote microwave image transmission, GPS signal transmission), microcontroller technology, computer control, application software, image capture, image recognition, inertial navigation, aircraft manufacturing and other technologies. I was fully committed to this competition, and during the nearly six months of commissioning the airplane, I was out early and back late almost every day. The UAV designed by our school realized the whole process of uncontrolled and fully autonomous automatic take-off, automatic cruise, automatic identification of static/dynamic targets, and automatic landing, which opened up the precedent of fully autonomous flight of UAVs in China. In the end, our team beat Tsinghua and many other famous schools and won the national runner-up.
The winter vacation of my senior year, when I mastered the microcontroller has been very skillful, thinking that I should learn the knowledge to develop some products, one can solve the cost of living on the expenses, the second just can also be rounded to my dream of doing business. Thinking that many of the same microcontroller beginners may buy the learning board, so decided to develop a microcontroller learning board in February to make the first prototype, in March to make the second version, the end of April to establish a personal website "Tianxiang Electronics" /, after three months **** improve the 7 version, and ultimately finalized TX-1C microcontroller learning board as the final product. In April, CCTV's "My Sun" crew came to our school to shoot a special movie for me, "My Sun - Innovation 360 Guo Tianxiang", which is based on my participation in 2005 "My Sun". I participated in the 2005 "Dragon Cup" China Air Robotics Competition as the background, about my years of innovative learning life in Harbin Engineering University, May 7 in the CCTV education aired, while my family in Xinjiang in the TV saw me have been away from home for several years, which is also the first time I was on the CCTV special program. The first time in my life, I was on a special program on CCTV.
From the second semester of my fourth year of college, I managed my own website while studying DSP (Digital Signal Processor), because I know that in today's rapidly changing technology, only a little bit of microcontroller and in the community based on the ten thousand, I must make full use of these years on the university campus, the fastest speed as much as possible to master a variety of electronic technology knowledge, once out of the Once on campus, I am afraid that there will never be too much time to study. As the school laboratory DSP experimental box, so it is much more convenient to learn, a DSP experimental box prices are in seven, eight thousand or even tens of thousands of dollars to personal ability to buy or a lot of effort. Learning hardware is mainly to do experiments, write the program, download the program, observe the phenomenon, think carefully, modify the program, and then download the program, and then observe the phenomenon of ...... so repeat, until you get the results of satisfactory phenomena, as long as you grasp this idea, any hardware will be mastered in a very short period of time. The second semester of the fourth year of college, my classmates are busy for their respective undergraduate graduation design, while I am designing their own DSP experimental boards, due to the DSP experimental boards use most of the chip for the multi-pin SMD package, so at least to be designed as a 4-layer PCB board, it was my first time to draw a 4-layer PCB board, with nearly a month to draw finished, thankfully, the board made out of the completely normal, I It took me another month to finish debugging it. Almost in 4 months time, I completed the DSP from the understanding of the board and then to the final debugging experimental board through the whole process. Because of the previous foundation of microcontroller, undergraduate graduation design for me is very easy, in most of the students spend half a year to study, I from the design to completion of less than 10 days, and in the 10 days also helped a lot of students.
It's time for the undergraduate graduation party, and most of my classmates' college lives have come to an end. I have watched how they have achieved their dreams step by step, and how they have repeated their lives over and over again, as well as how they have fallen down day by day. From that day on, everyone will usher in their own brand-new environment again, where maybe some people will be glad, maybe some will regret, but no matter what, their own road is their own choice, of course, they have to walk on their own.
The ocean of knowledge never ends, and I can't stop on the road. I haven't waited for graduate school to start yet, and I've already made a comprehensive plan for these 2.5 years. From the beginning of the vacation, I began to contact ARM (embedded systems), in my opinion, if it does not involve ARM's operating system, then it is still the same learning method as the microcontroller, in the beginning stage, I take it as a piece of microcontroller, of course, it is much more powerful than a microcontroller. Half a year later, I and my classmate Song Baosen and Yu Zhennan three **** with the undertaking of a Samsung ARM7 as the main controller of the project, the project involves a very wide range of knowledge, covering the microcontroller system, embedded ARM7, GPRS network, Internet applications, image acquisition, image processing and remote transmission, TCP / IP protocols, mobile communication technology, Code Division Multiple Access (CDMA) technology, network data parsing, analog circuits, digital circuits, high-frequency circuits, RF wireless data transmission, industrial sensors and other technologies. In this project design, I found that the above I mentioned these areas of knowledge, not a few of my college majors to learn, even if learned, but also not many are really able to be applied to the actual in the high-tech-driven social progress today, simply master a narrow field of knowledge is far from enough, we can only continue to learn, and continue to apply, and then learn again, with this attitude in order to make knowledge We have to keep learning, keep applying, and keep learning again, and with this attitude, we can make the knowledge be maximized, and let the science and technology progress continuously.
In early 2007, through the school's scientific and technological innovation project, I declared the "remote wireless controllable submersible" project, and finally to the whole school's only mega key project was approved, the school and the hospital have given full financial support, after five months of hard work by me and my team members, our work finally tested the water. After 5 months of hard work by me and my team members, our work finally tested the water and succeeded. The work was awarded the first prize of the school's "May 4th Cup" in 2007, and the first prize of the "Challenge Cup" electronic design competition for college students in Heilongjiang Province in the same year. By the time I left the school, the project was still being further improved by other members of the team.
In the first phase of the study, I used the two summer and winter periods in the school held a ten-day microcontroller training courses, I use a new way of teaching to beginners the easiest way to get started quickly for the students to explain the use of the 51 microcontroller, I led the students to do experiments in the classroom, and then every day after the class the students to practice writing their own programs, after ten days of intensive training, the end of the course, almost all the students were able to independently program and operate the 51 microcontroller, the students were able to program and operate the 51 microcontroller, the students were able to program and operate the 51 microcontroller. After ten days of intensive training, at the end of the course, almost all the trainees were able to independently program and operate the various functions of the 51 microcontroller. In the "Sony Cup" National Student Electronic Design Competition in the same year, I served as a school instructor, in the competition site I saw many students who used to listen to my classroom figure, and they eventually achieved gratifying results, I sincerely feel gratified. In order to let more microcontroller beginners benefit, I will teach the whole process of video recording, and then released it to the Internet free of charge, since the video released on the Internet, has been a lot of students highly praised, and even many foreign students called me to thank me.
In September 2007, I went to an energy company as an intern to do my master's project. At that time, there were many other undergraduates from other colleges and universities with me, who majored in the same field as I did, as well as those who majored in automation. I and a few old staff is the only company can independently develop projects and really understand the hardware programming people, we take a high salary, and the company also treats us as a baby, other new college students in the praise of our ability at the same time also sighed in their own university in the end what they learned, from the helpless tone of voice I can see their remorse, however, today, they are in the reality and what can be done about it? Six working days a week, eight hours a day, late deduction of wages, early dismissal deduction of wages, leave deduction of wages ...... This is the unchangeable reality in front of them, waiting for the arrival of that day every month, and the thin envelope is only enough for the basic living expenses every month. Young friends ah! The same is from the university campus out of college students, this is the gap, and this is only the beginning of the gap. During the internship period, in the exchange with the company's technical staff, in the product step by step to improve the perfect, my professional knowledge has been further sublimated, I y realize that, only the theory on the books and not with the actual hardware combination of practice, the theory is useless; only in the campus to do the simple hardware practice, if not with the combination of industrial field applications, the practice is immature. Until I left the company in June 2008, I developed a series of solar charging/discharging controllers, solar street light controllers and solar power station charging/discharging controllers for Unicom's mobile base stations for the company, and they have been mass-produced and applied.
College life is the most valuable experience in our lives, we pay the price of four years of time, we should also must be gained for this. Many students in the university campus lost their way, do not know what they came here in the end for, simply think that after graduation to find a good job on everything, but have you ever thought, no real skills how to find a good job? How can you contribute to the society? More realistically, without a good job how to buy a house to become a family, to build up your own happy happy home?
