1. Buy a book about computer hardware.
There are many on the market, which are relatively easy to buy. Buy components comprehensively, and each component does not need to be too deep. Let yourself have a clear understanding of the whole system first.
2. Find a practical environment.
Go to the computer city to install the machine. The bigger the computer city, the better. This is a key suggestion. A wide range of fields will certainly come into contact with more things than a small field.
3. Start focusing on one component.
With a certain theoretical accumulation and practical experience, I began to conduct in-depth research on some important hardware, and of course I can't do without it. Working in the computer city, it is inevitable to collect a lot of damaged and scrapped hardware. Take it apart and think about the principle of hardware production structure theoretically.
4, began to understand some hardware programming.
Although computer maintenance costs more hardware, it does not mean that software can be completely ignored. For example, a module and the main chip cannot communicate stably. Is it timing or chip instruction set? This requires a background of hardware programming knowledge to locate. The practice of hardware programming needs not only hardware disassembly, but also hardware programming development and debugging environment. In terms of books, it is recommended to buy a traditional 8086 compilation and an ARM architecture book. 8086 is the instruction set of intel's CPU, which is applied to desktop computers, and ARM is the simplified instruction set of ARM, which is applied to tablet computers.
5. Start to independently write chip programs and independently develop patented chips.
This level is to develop application chips, design hardware solutions, and design PCB circuits based on chips. In this process, it is best to buy foreign original English books. If you can understand English, you'd better not translate them. Because the hometown of computers is the United States, the underlying content is still American majors and standards after all.
