Zhou Ligong Company's "Electronic and Communication Hardware" written test questions.

I don't want to send you the title of the software irresponsibly.

Because the topic of hardware is so long that you can't remember it at all, there are only C/C++ topics on the Internet.

I looked up some relevant information for you. I suggest you review it yourself. According to other people's experience in written examination, we can see that the examination mainly examines the basic knowledge of single chip microcomputer and some basic knowledge of electricity counting.

Electronic communication hardware (single chip microcomputer, amplifier and other topics)

The written test tested some basic knowledge of electricity counting and analog electricity, mainly electricity counting. Single chip microcomputer, AD, c language programming. If you review well, it's not difficult. I feel that this kind of exam is not very good. Just review the theory well. It doesn't matter if you have project experience. The difficult problem is how to generate the sine wave of 1KHz with single chip microcomputer through Ada circuit, which is impossible. On the one hand, because I am a single chip microcomputer and embedded, it is relatively simple to ask me about the knowledge of single chip microcomputer, such as the minimum system, the address allocation of RAM, the address of interrupt and so on. The topic of FPGA is not difficult, but also very basic. The two most typical ones are full adder and automatic beverage vending machine. It is said that there is only one VHDL or Verilog programming problem and several very simple definitions of terms, such as setup time, hold time, clock srew, multi-cycle path, and others focus on electricity counting, especially D flip-flops.

I have sent you a question on the school BBS, and I will let you know if there is any news.
