Ask the great gods to give some advice to my younger brother who wants to switch to embedded system.

If you want to do embedded development, first of all, your C language should be excellent. The excellent here is to be very proficient and be able to play C fluently. Secondly, embedded needs to master assembly language, as long as you are familiar with it. Learning MCU does not mean that you can enter the embedded industry. At present, the recruitment of embedded systems generally requires work experience and bachelor degree. Embedded system porting is about the code in the kernel, so you should be familiar with the kernel, and the driver is that you write the code into the kernel. Non-computer estimates that you are not familiar with the Linux kernel. Then it is relatively difficult for you to learn. Even after months of training, you can't learn anything deeply. So embedded is difficult to learn. You have everything except what I said before!

You can participate in the training of c/c++. One is that c/c++ is easy to learn, the other is that the salary of c/c++ is not low, and the other is the upper-level thing that is easy to operate. The salary in Beijing is at least 4000.

Followed by software testing, Beijing's software testing salary is around 3500, but it is relatively easy to learn and work.

If you don't know much about it, you can keep asking.

I hope I can help you, and I hope it is a satisfactory answer.
