This summer vacation, I am fortunate to enter the electronic design competition of Dilly and other classics, which is mainly responsible for completing the serial driver of the system reader and GPS. In this process, I feel that my progress is still very big. First, there is a chance to practice a development project process; secondly, the method of using the Linux system and programming methods, contacting the drivers under the Linux system; again, can work with the participating groups The competition, it is a matter worthy of my pride. Now the game is over, although the result is not very ideal, but by identifying the cause of this situation, you can provide a little reference for future development, so you will summarize my lessons here.
One aims a little off
The direction problem is that we have discovered in Beijing Post. Because the judges of the judges seem to be very interested in our system, the focus of their concern is not completely coincident with us, for example, we are mainly on the board On the display, through the software running interface to demonstrate our system, but the teacher did not look at this, but asked what the maximum machine card of the card reader can successfully read the card, how much is, dizzy, this is going to ask Cart manufacturers, because the card reader is we bought. When I think about it, we are indeed a bit of a copy, this is an electronic design contest, not a software game, the most hard "work we do, but only solder several serial lines and interfaces.
Two shots slow
Look at our first plan, then recall the actual process, can't help but have some sweat. We have not had a complete and stable system, not to mention the complete test. The true development should be started in mid-August, and the time is more than half a month. When I ginseng in North Post, the magical F-22 won the first two days before the presentation, and the Flash animation of the PPT demo was also decided in the last day, plus the use of a good time and the use of computers. I finally failed, I was regrettable. Remember to write a software book: No matter how much you give us, we will also put it on it. It is also the sentence, you must strictly strictly keep the plan schedule (of course, you must first have a good and reasonable timetable), in order, try to plan ahead, because it is always difficult to predict the difficulties will appear in the future, inevitable will Cause some delay.
Three trimesters
Quote A smile often said with MSMouse is to use my card reader to read the card, the first pass is successful! The second copy fails ... the third time is successful! The fourth time has failed ... Summary: The odd number is successful. If this is downgrade, it is a pity that the card reader actually comes to a dead book, only two cards in the four cards, depressed, soil is uncomfortable than us. The stability problem to be said is actually a child problem of the last problem. Since the development progress is not allowed, we have not given a point to complete the system, and later the card reader drives the problem, affecting the demo effect, I am a pity, I am sorry. In the future development, it is necessary to mention the test work to look and arrange the same position as the development work, and it is not possible to not test J.
Four small materials micro
I don't dare to use the words of this fire, so I don't have the meaning of my job task. I just wrote the code that hundreds of lines, I didn't do anything else, so that everyone is the most busy. When I didn't help anything, I'm going to do, and the light is waiting for the overall test. When you develop, you must have a lot of life, and you need more balance when the leadership schedule will need to break the difficulty.
Five concluded words
The final project is still gains three prizes, it is not easy, and use a sentence to summarize: we have done very well; we can still do better. So, look at the next time!
