Preface

Briefly share the overview of the competition and the experience of participating in the competition

1. Introduction

The Blue Bridge Cup is divided into provincial competitions and finals. Players who get the provincial first prize in the provincial competitions can advance to the national competition (finals). The finals are generally held in Beijing.
Provincial competition time: from late March to early April
each year. National competition time: about May each year.
Competition duration: The single-chip microcomputer group is a five-hour
competition board: Taobao link

2. Introduction to the topic of the competition

There are ten multiple choice questions (30 points) and one programming question (70 points).
1. Multiple-choice questions involve course knowledge of circuit analysis, analog electricity, digital electricity, and single-chip microcomputer.
2. The programming problem is a program written in C language, and the programmed program is written into the single-chip microcomputer through the burning software to complete the functions required by the competition topic. There was also a circuit design problem in the previous SCM competitions, but it was cancelled later.

Three, learning methods

(1) For multiple-choice questions, there are single-choice and multiple-choice questions. Although they are relatively basic, they cover too much knowledge and can’t make much preparation. They can only brush a few sets of questions or learn from previous years. Understand the basic knowledge of these subjects (actually, it seems that there is not so much time).
(2) For procedural questions, you must first be familiar with the use of each peripheral device, and then gradually practice to integrate them. The last stage is to do the main topic of the competition, so that you can write down several sets of competition procedures by yourself.

4. Participation process

1. Registration:
In December of each year, the official website will post the registration notice.
2. Preparation: If the
preparation phase is normal, it may take four to five months, and there is a winter vacation, so the preparation time is still very sufficient. What are the specific preparations? , The following details
3. Participation: If the
competition is normal, it should be in March and April. You can participate in the national competition after you get the provincial one. After the provincial competition, there will be less than a month to prepare for the national competition. If the provincial competition is fully prepared , The national tournament has one month to prepare, and you can also prepare for the provincial and national tournaments in advance.

5. Specific learning content

1. Browse the official website information and grasp the general competition information ( official website )
2. Download keil, serial port driver and burning software
(1) Go to the Internet to find the keil download. There are installation packages and related installation tutorials. The keil5 used in the competition seems to be.
(2) The installation package of the serial port driver is in the resource package (link) I sent (it will also be provided during the competition).
(3) The burning software uses stc-isp, a .exe executable file, which can be directly run and used in the resource package.
3. Learning the content of the competition
After the above preparations are completed, you can officially start the MCU learning journey! In terms of my own learning experience, I learned the following:
(1) A teacher's tutorial on bilibili, which is very good, and it is mainly free. Many of us followed that, involving 99% of the competition. The knowledge points are very awesome, this is the website ( https://www.bilibili.com/video/BV1Bt41187hw?p=1 )
(2) When you encounter problems, you can check the relevant content on CSDN
(3) and then Just go to the problem directly and do it from the back to the front (the one with the shorter time is more valuable for reference). The first set is definitely more difficult, mainly to learn how to do it, and then write one from the beginning to the end, where you are stuck Just look it up. This is an indispensable process and a very valuable learning process.

6. Summary and personal suggestions

This is also the first time I have participated in a more formal competition. Generally speaking, I have invested a lot (our session has been delayed for a year due to the epidemic), and I have received a relatively satisfactory return. In fact, the MCU group is less difficult than the software group (in terms of the eleventh), and the national competition is not much more difficult than the provincial competition, but the logic is a bit more complicated, and the peripherals are not more complicated than the test ( It may also be affected by the epidemic), but we still have to learn things in order to deal with it calmly, so everyone should prepare for the provincial competition and move towards the national competition.

At last

比赛完已经有三个多月了，实际参见比赛时候强行记住的东西还剩多少？那几年后，剩下的东西还有多少？所以我觉得，参加比赛或者学习一个新的东西最重要的并不是非要取得什么名次，完完全全记住多少知识点，我们不可能知道我们以后工作需要用到什么东西，而且现在很多东西都是可以现用现查的。所以我认为最重要的是处理一个完整的复杂的问题的思维和分析问题并探索地去解决问题的能力才是应对各种各样新的复杂的问题的终极法宝。
祝愿大家都能在日积月累的学习和探索后获得这样的能力！
