Embedded self-study, okay? Single-chip microcomputer has a little 5 1 foundation, and the analog electricity is not good. I know a little about counting electricity. Can I go to training? Will it be difficult to keep up? Honestly, it shouldn't be easy. In this case, it is better to go to training. After all, self-study is not that simple. If the landlord wants to learn, it is better to find a good training institution. It's really a good springboard. At present, many training institutions are engaged in employment, and the wages are very good. At least what I know is very good, and many of them have good jobs. Hehe, it's very important to give some advice to the landlord, don't be afraid before you start, and give yourself some confidence. Come on, take the time and work hard, and the result will not be worse.
