Read your letter, first felt your strength! ! You said there is no direction, in fact, this is also confused by many people, some people have not found the direction in their lives. No matter what you do, you have to think about it, and you must be very clear: [What is your goal is to do, what is your goal? ] In fact, what industry is not important, it is important that you can become the elite in this industry! ! If this problem solves, your life has been successful. Remember to solve the goal first: Because you don't know the direction of your efforts, it is useless. People's potential is infinite, but people's energy is limited, and you can't try it all things! ! Nothing is necessary! ! In fact, everyone's so-called "research and development" is usually based on technology, that is, what technology I have, and then based on this technology. Not through market research - customer demand analysis - product positioning - product development - productization - commercialization, this is not suitable for future trends. It is also one of the major causes of vicious competition in the market and the loss of corporate losses. It is important for you to locate your own position. If you really want to develop technology, it is still a direction, one field. The electronic field is too wide, it is impossible to learn, at least I personally think. In terms of specific techniques: 1,51 architectures you must be very, very, very familiar, I don't mean it, but really proficient! ! ! ! ! Because all microprocessors, the controllers are all the hundred things, familiar with one of them, others come quickly. 2, the simulation circuit is usually a weak term, but the power circuit, small signal amplification circuit, and small signal processing circuits must be mastered. 3, the system and on-site interference processing should focus on flowering, you can build your advantage. 4, language does not have to learn too much thing, very familiar with C language and some kind of compilation, do not ask new! ! 5, software recommended that you use UCOS, transplant your own hand, focusing on understanding its operating mechanisms and system architectures. Not recommended to get started with Wince, VxWorks or QNX! ! 6. Tools: Protel is very familiar, I refer to every module, not just SCH and PCB. UML tools should pay attention to what other uses to learn. Don't ask new! ! 7, device: ARM, especially pay attention, module: LCD is familiar, at least monochrome, false color and TFT! !
