You may have heard about embedded technology, but you don't know much about what embedded technology really is. In fact, embedded technology has penetrated into various industries, from small mobile phones, PADs, routers, digital cameras, to medical devices, aerospace equipment, etc. All of them are typical embedded system products. Embedded engineers have become one of the most promising careers at present.
Is it difficult to learn embedded development? How long does it take to learn embedded development? Follow the specific small series to find out.
Embedded OutlookCompanies that do embedded systems generally have their own products, and the products they develop are universal. On the other hand, the scope of work for each person engaged in embedded is relatively narrow, and the scope of professional technology involved is just a few samples. After such a long period of time, these knowledge become more and more experienced, they have a sense of accomplishment, and they wait for a certain age to buy and sell. Ben, a few know that will allow those who just entered the company's debut to admire the five-body field, as well as if they are found in the industry, you can also start your own business. In recent years, with the development of smart phones, tablet computers, and broadband routers and terminals, the demand for talents in this area is still objective.
At present, people at home and abroad are scarce.
On the one hand, because of the high barriers to entry in this area, not only to understand the underlying software (such as operating system level, driver-level software), the higher the level of professional software (embedded system time and space efficiency of software design High requirements), and must understand the working principle of the hardware, so it is difficult for non-professional IT personnel to enter this field;
On the other hand, it is because this area is relatively new and currently developing too fast. Many hardware and software technologies have not been around for a while or are emerging (such as ARM processors, embedded operating systems, MPEG technology, wireless communication protocols, etc.) Of course, new technology people are looking for (embedded technology training: ARM development training, FPGA training, DSP training, etc.). The scarcity of embedded talent is naturally high. The more experienced the price is, the higher the price is. In fact, there are few embedded talents. The basic reason may be that most people have unconditional contacts. This requires corresponding embedded development boards and software, and requires experienced people to guide the development process.
Unlike application software such as enterprise computing, the work intensity of talents in the embedded field is usually lower, but the specific income is not low.
To engage in enterprise application software for IT companies, the user's system is finished, and then go to engage in the next user, and each user's needs and completion time have to change according to customer requirements, often exhausted, repeated labor. In contrast, companies engaged in embedded systems have their own product plans and act at their own pace. The products developed are generally generic and will not be modified by customers. After a product model is developed, there is often a long period of idle time (or just minor software repairs), and there is time for charging and rest.
In addition, the scope of work of each person engaged in embedded software is relatively narrow, and the scope of professional technology involved is those (ARM, RTOS, MPEG, 802.11, etc.). These things will become more and more experienced after a long time, selling and selling old books. A few guides are enough for those who have just entered the first half of the year. If you engage in application software, it may be difficult for the next customer to switch to a completely different software development platform. If you want to enter the embedded development industry, the recommended training courses include: embedded Linux development training, embedded WinCE development training, Linux network programming and development, embedded development and application training.
Of course, if we are engaged in embedded development, this is not entirely an advantage, or there will be insufficient points, but its shortcomings are:
(1) The starting point for getting started is high, and the techniques used often have certain difficulties. If the software and hardware foundation is not good, especially if the operating system software is not well-founded, it may not be suitable for this line.
(2) The number of enterprises in this area is much smaller than that of enterprise computing companies. In particular, there are a large number of small businesses engaged in embedded businesses (smaller companies must engage in their own product ventures) and fewer well-known large companies (large companies engaged in embedded companies mainly include Intel, Motorola, TI, Philip, Samsung, Sony, Futjtum, etc. Manufacturers of Bell-Alcatel, STMicroelectronics, Microtek, Advantech, Huawei, ZTE, and SVA. The customary way of thinking of these companies is to look for people in hard-to-find professions such as electronics and communications. Due to the fact that graduates from our college were mainly based on business calculations, our institute has relatively few contacts with these companies. Our institute is actively working hard. At present, we have established contact with some of these companies and we hope that we can have our students in these universities to practice or find jobs in these companies.
(3) There are a few companies who often have masters or graduates or more engaged in embedded, mainly based on the difficulty of embedded. However, most companies do not have this requirement, as long as they have experience.
For zero-based people, how to start embedded learning? If it is an electronic or computer professional, relatively speaking, it will be easier to get started; rather than an electronic or computer professional, you should start with basic circuit and C language programming.
Mastering embedded development is the same as mastering other things. It needs to be gradual and persevering. Step by step, your perseverance, and finally learn embedded development.
Learning embedded, you can get started from the following aspects.
First, analog \ digital circuit, C language programming.
Analog circuits are more difficult to learn, you can choose to listen to some video tutorials, take a look at the most basic textbooks, and have time to do some simulation experiments on Multism; digital circuits are easier to learn, learn video tutorials on the line; whether to do embedding The software is still a hardware developer, and it is necessary for the mastery of C language. Especially for those who are committed to embedded software development in the future, most of them are now developed in C language. After doing this, the preparatory work was basically completed.
Second, MCU
Mastering proteus simulation, you can learn without buying hardware. To learn the SCM, one is to master the various resources of the SCM, and the second is to master common components and buses.
Third, the embedded operating system
Learning embedded systems, such as Linux or wince programming, is helpful for future application programming. You should understand the operating system. This will definitely help your understanding of hardware and software. You should understand the management of the system, such as processes, threads, how the system allocates resources, how the system manages hardware, and so on.
Fourth, ARM learning
Combine the ARM chip manual to learn the UBOOT source code, understand the next smallest system development, that is very helpful to your entire embedded development, if you can, you can also learn the source code of linux, take a look at the early version of the Linux code , such as the 0.12 code, etc. If you have finished reading it, you are basically getting started.
Learning about embedded is probably the beginning of these four aspects. When you are learning, you can choose according to your own conditions, you can read books, you can also watch videos, but the most important is the hands-on operation.
How long does it take to learn embedded? The shortest cycle of learning methods is usually four months. It does not seem to be very difficult. It is nothing more than trying to embark on the pinnacle of life. However, as far as the current embedded talent market is concerned, it is more of a junior embedded development talent, so now it is mostly through the participation of a certain amount of embedded training and then continue to learn and accumulate in the work, and the big gods that have grown up step by step. , can be regarded as a shortcut.
1. Understand the embedded hardware knowledge, including hardware foundation, composition, principle and interface technology, etc.
2, proficient in C language programming, because the embedded is to rely on the C language to develop applications, so do not understand the C language, all talk.
3, familiar with embedded system knowledge, such as nowadays more popular embedded linux system, to be familiar with its kernel code, and run commands, use methods and so on. Understand the characteristics of embedded product R&D, the technical specifications and key points that need to be mastered.
4, has the most basic hardware and software application development capabilities, such as need to understand how to develop applications, how to deal with hardware and software compatibility issues.
5, specific good creative development capabilities, which is necessary to become an excellent embedded development engineer, but also the most important and most valuable. Because we have to constantly develop new creative product features to meet the tastes of today's consumers. Therefore, creative development capabilities are also the best expression of a good developer's ability.
6, have the ability to work hard and continuous learning, as an embedded development engineer must have the ability to bear hardships and stand hard, after all, software development is a very strong project, and secondly, excellent engineers also need to continue to learn The capability, the development speed of the software industry, and the development skills and experience that they are proud of today may become a thing of the past two or three years. Therefore, developers are required to have the ability to continuously learn and accept new things. Wanting to become a good embedded development engineer is not an easy thing to do, but also accumulated through long-term learning. In fact, there are very few such excellent embedded development engineers. This is also the talent that many companies seek.
