The most important thing is to determine your own goals. It's a long way to learn MCU. It's not a temporary passion, but something that will fade away after the past. I want to do research and development, see if you have the conditions.

1: I like electronics very much and have great interest in them.

2. The degree of obsession with electronic liking.

3. Be able to stand loneliness.

I have the ability to think independently.

5. Self-study ability.

These conditions are very important. R&D is an innovative work. Most people can't afford it. They go to work to write code every day and go back to work to write code until 2 pm. You are learning new knowledge every day in the process of research and development.

When I encounter problems with R&D products, I will solve them one by one. I have an experience in R&D now, which requires a process.

If you think you have the conditions, you can buy a 5 1 single chip development board first. I bought a study board from Mr Guo Tianxiang in college that year. After watching him for ten days, I learned the single chip microcomputer and taught you with Mr. Song's hand. I started writing a program from a simple running lamp and accumulated my own experience. Note: To thoroughly understand C language, apply 32 keywords of C language to each experiment one by one, and master grammar. Don't write more programs to accumulate experience. 5 1 I taught myself almost a few little things, and then I went to learn STM32 single chip microcomputer, which is now the mainstream single chip microcomputer on the market.
