Blue Bridge Cup

Preliminary preparation

The Blue Bridge Cup competition was delayed for nearly 7 months due to the epidemic. It was originally held in March, but it was postponed to October. I was already ready during the winter vacation. I have already brushed up on the national and provincial competitions. , However, it is very uncomfortable to delay and delay. . .
First of all, we must understand the schematic diagram of the Blue Bridge Cup MCU, and understand it in modules. Here, we will first upload the complete diagram and explain it in detail in the module analysis and programming implementation later.

October provincial competition

I participated in the Blue Bridge Cup MCU competition in Jiangsu Province. The test site was at Jinling Institute of Technology. I took the subway from school for nearly two hours and threw up.
The competition is also more casual, even if I don’t mention whether or not to hand over the mobile phone, no one asked to put it in the front. The seats are not separated. They sit next to each other. The multimeter is used by two people at the same table. The competition questions are relatively disappointing and I have been reviewing for so long. I took the temperature sensor and D/A conversion test. The objective questions are more difficult. It opens the gap. It requires a lot of basic knowledge. It took less than 2 hours to finish the whole question. I bit my head and read the STC MCU manual for an hour. Looking for the answer to the objective question, I couldn’t stand it in the end. I handed in the paper at 12 o’clock. There were 2 hours left for the test. After the test, I was not happy and felt humiliated. It was almost ten days. I can’t go to the Beijing final after the final, hey.

National Games in November

The national competition test site is at Nanjing Normal University for Special Education. One of my classmates is there. After the test, you can also reminisce about the past, hehe.
The national competition was a little more formal, but the previous notice was not in place, which caused some candidates to fill in the health form. The process after arriving at the competition building was still in place, but there were still several people sitting in the exam. In one piece, the multimeter that the electronic test takers brought was also useless, and the program question was still very simple. I tested the temperature sensor 18b20, A/D, real-time clock DS1302, and matrix buttons. I feel that those who have entered the finals have hands. The objective questions I actually feel are a little simpler than the provincial competition. It took almost two and a half hours to finish it. I wanted to hand it in early, but I couldn’t get out of the exam building ahead of time. After sitting for two hours to check the chip manual to find the answers to the objective questions, in the end, there was still half an hour to hand in the papers. Come out to practice classmates chatting in the building. After the exam, I wandered around in Nanjing Teachers College for Special Education. The school is not big, the place is relatively small, the scenery is good, and it is quiet. There are some deaf-mute students in the school. They are suitable for resting and resting. I feel that this topic is just coming. For a fool, I have done so many preparations to measure the frequency, ultrasonic, serial port transceiver, long and short keys on the NE555, and prepare to fight against my skills. The result is disappointing. After the test, the teacher asked how it was, "It doesn't feel very good, the test is too simple, I feel that everyone will do it."

Missed result release

I heard that the results of the Blue Bridge Cup National Tournament will be released one day later. They say it’s noon the next day. Before that, I went to the study room and went to bed. I slept at one in the afternoon for an hour. I got up and saw the senior send me a message. In our country, I was not at all happy or surprised. I didn’t have any emotional fluctuations. I even wanted to keep sleeping. Maybe I missed the release of the results. I didn’t feel excited when I went to check.

Want to do something, pass on

My teacher heard that our two students both took the National One and I was so happy from ear to ear. The next day in class, I started to promote the Blue Bridge Cup with my next-level classmates. I will participate in anyway next year. The Blue Bridge Cup embedded competition.
If there are future generations who want to participate in the Blue Bridge Cup MCU competition, they will definitely come to ask me this excellent senior (boasting), but I am too lazy to teach others, in order not to relearn this board in the future, I decided to put mine on CSDN The experience is written down.
Later, I will publish the programs and real test programs of each module of the Blue Bridge Cup MCU.
