Several essential skills for MCU engineers

1. Strong hands-on ability. If you are clumsy, either work hard to become an expert or change your career!

For example, I am the type who can use my brain but not my hands. However, after training,

The 20mil pitch TQFP package is solderable.

2. Broad knowledge, including knowledge of software, hardware, electronics, mechanics, physics and mathematics.

You don't have to be an expert in everything, but it's best to know a little bit. At least you have to have a basic idea.

3. Strong learning ability. There are new skills and knowledge to learn every day.

4. Be brave enough to take apart anything and have a look. Have the courage to repair anything.

For example, I don't know anything about computer hardware, but my computer has broken down several times. Last time, the fan broke down.

I removed all the components and replaced the fan, and now I can install the computer without any problems.

My computer is giving me problems again. There are always BIOS errors. I have refreshed the BIOS many times but it still doesn't work. I have no idea what is going on.

Today I suddenly remembered that the battery on the mainboard might be dead, so I just replaced it with a new one.

5 You need to have the intuition of a technician, or in other words, you need to have the ability to understand. If you don't have it naturally, you can only rely on hard work.

6 Be diligent. Lazy people are destined to mediocrity.

7. Have a spirit of research and dedication, and treat MCU as an interest, hobby, or career instead of a job.

Come and do it. Which of the experts in the forum has not stayed up until 1 or 2 o'clock in the morning? For me personally, making a website is simply a love.

Well, there is no benefit from investing and it takes a lot of energy, but as long as I like it, that’s fine.

8 Be humble. Everyone grows gradually. Ignorance is fearless. I have experienced this. The more I learn, the more I feel I am not

OK. Arrogant people will never become masters.

9 You must be able to endure the loneliness and pain of growing up. I once met a small boss with an annual income of one million.

Engineers, who only sleep 4-5 hours a day, are really like gods. But only hard work can bring rewards!

10 Several essential skills: Master at least 1 EDA software (protel orcad powerpcb, etc.), at least 1 high-level language

(generally refers to C), at least 1 RAD language (such as VB BCB DELPHI, etc.), at least 2-3 MCU cores,

At least understand the basics of digital circuits and analog circuits, and at least some pure software knowledge (such as data structures, software engineering, etc.).

programs, some algorithms, etc.).
