What makes a good embedded engineer?

In the field of IT applications, the popularity of embedded systems is probably not lower than the current outdoor temperature, in industry, medical, home appliances, communications and other industries, the ubiquitous embedded system shows great potential for development, however, the lack of embedded system talents, has become the main bottleneck that restricts the further development of this industry, whether in Beijing, Shanghai, Shenzhen or the mainland, the most headache for human resource managers of embedded enterprises is that there is no way to find enough embedded system engineers for the enterprise, Compared with the hundreds of thousands of fresh college students who can't find a job every year, it has become a stark difference.

So, what hinders the cultivation and emergence of embedded system talents? In Changsha City's first professional embedded training base - Changsha Yingteng Information Technology, the author learned that because the embedded system belongs to a young science and technology, in the domestic higher education institutions, has not yet formed a perfect and efficient training institutions, although many outstanding science and engineering students are optimistic about the embedded system, but because they can not find a suitable learning path and learning method, it took a lot of time, took a lot of detours, but has never been able to enter the threshold of the embedded system.

How to become a qualified embedded system engineer, the training teacher of Inther Technology suggests that first of all, it is necessary to fully learn and have a comprehensive understanding of the C language, which is the basis of IT system development, especially to master the standardized programming skills and prepare software development documents, and lay good programming habits from the beginning; Secondly, you should have enough understanding of logic circuits and analog circuits, understand the ins and outs of circuit design, in this regard, you do not need to learn any advanced application technology, but the basic skills must be solid, and you must have a full understanding of the basic principles and design methods, that is, you do not need to be able to design a circuit board, but you must be familiar with the mainstream development boards on the current market; With these foundations, you can involve the principle and programming of the embedded operating system, although in this regard, there are a lot of information (most of which are in English) for reference, but learning under the guidance of an experienced teacher is the fastest way, in Changsha Intel technology has graduated nearly 1,000 students, most of them can be completed with the help of the teacher in 2 and a half months to complete the mastery of theoretical knowledge, if it is self-study, the time is at least more than 1 year.

To lay a good foundation to learn the number C language, you mainly have to write programs by hand! You can never see it. Write down more hands-on** and follow the experiment instructor step by step. You can't learn if you can't catch up with time! I wish you success!

With the development of informatization, intelligence and networking, embedded system technology will also gain a broad space for development. When the famous American futurist Negroponte visited China in January '99, he predicted that in 4 to 5 years, embedded intelligence (computer) tools would be the greatest invention after the PC and the Internet.

Learning the sea is endless, hard work, and practicing the foundation is good, and then practice and study will become a master. Trust you.

An embedded engineer is a job that engages in the development of embedded devices.

Develop some of the lowest-level software that is most closely related to hardware, such as bootloader, board supportpackage (like a PC's BIOS, driving the hardware down and supporting the operating system up), the most basic hardware drivers, etc.

Engaged in the development of embedded operating system and application software, after the embedded hardware is designed, various functions are all realized by software, and the value-added of embedded equipment largely depends on embedded software, which accounts for the most important work of embedded systems.

Embedded engineer salary

According to the statistics of the embedded engineer treatment department, the embedded talent gap in China is about 500,000 people every year. According to the survey report released by Recruitment**, embedded software development is one of the hottest and most popular professions in the next few years, and the salary of embedded practitioners is about 50% higher than that of other IT industry peers, and generally in first-tier cities it will be much higher than other places.

The annual salary of a senior embedded engineer with 10 years of work experience is about 300,000 yuan. Even for junior embedded software developers, the average monthly salary has reached 3,000-5,000 yuan, and the average monthly salary of trainees who have completed the training is generally about 8,000 yuan.

The usual job of an embedded software engineer is to be responsible for the planning, design, coding, and testing of embedded software systems. Embedded is divided into two aspects: operating system and hardware, and the direction of employment is broader and deeper, and the employment opportunities and entry treatment are better than those of ordinary software engineers. Develop some of the lowest-level software that is most closely related to hardware, such as bootloader, board supportpackage (like a PC's BIOS, driving the hardware down and supporting the operating system up), the most basic hardware drivers, etc.

Embedded Engineer (Embedded Engineer Shan Kuansun) must master some theoretical knowledge and practical skills, or chain of a total of seven points, please see below:

1. At least have a basic understanding of the wiring of the power supply in the printed circuit board, understand what consequences poor layout and wiring will have on the quality of the power supply, even if you have never designed the wiring of a circuit board by yourself, you must be able to debug the problems that may be caused by the chaotic layout of the printed circuit board. Howard Johnson's book "High-SpeedDigitalDesign-AhandBook of Blackmagic" is very helpful in learning this.

2. Similarly, there should also be a basic understanding of how the wiring of the printed circuit board affects signal propagation.

3. Have the ability to read circuit diagrams.

4. Understand the various types of IO configurations of digital components such as microcontrollers, MCUs, such as OpenCollector (OC), Open-Drain (OD), Push PullOutput (TotempoleOutput), and whether there are protection diodes. In particular, it is important to understand the issues of level shifting (today's systems tend to have mixed IO voltages) and driving different loads. For example, if you want to drive an inductive load similar to a relay, but the circuit design does not pay attention to the inductance characteristics of the load, when the relay is opened or closed, there are all kinds of strange phenomena.

5. Master the simple techniques to reduce the ESD sensitivity of the system, such as selecting the appropriate grounding position, and Huilongguan computer training recommends the correct placement of discharge diodes, series resistors and grounding capacitors.

6. Learning to use SPICE circuit simulation software is very helpful, but not absolutely necessary.

7. Master the practical skills of hardware debugging.
