Embedded system self-study

If it is only for the computer level examination, it is very simple. Just buy tutoring books and do the test questions. Basically, the questions he answered were drawn from the question bank. If you want to learn about embedded, or want to work in this field in the future. I still need to buy a development board.

Learn the embedded Linux operating system, purchase the main control development board of ARM9 or above, and require at least serial ports and network ports on the development board.Learn the development of board-level support packages, cross-compilation, GDB debugging, UBOOT porting, kernel porting, root file system production, device tree, driver writing, and network programming related knowledge.

I was also self-taught embedded at that time. Personally, I felt that it was difficult to get started, and then it was the same as all other industries, relying on accumulation. I have a basic knowledge of Linux (I have used the Linux system for a year), so I also pay attention to Linux embedded.

It is recommended that you do the application development direction (with embedded operating system), and the following modes are recommended: J2ME+Java. You can use the WTK development environment, use WTK's simulator or your own smartphone as a development platform. Develop mobile games, which is the most suitable for computer majors.

Master advanced programming in C language.Whether it is embedded software or hardware development and programming, it is an indispensable part. Therefore, whether you are self-seeking or worshiping, I firmly believe that this is the first step they teach you. To understand the embedded Linux operating system.

Key points of embedded development learning?

1. Learn embedded technology. I think there are two key points, cpu and operating system. At present, arm is relatively popular in the market, so I recommend everyone to learn arm. There are many operating systems. Personally, I recommend ucos to those who are starting to learn, especially those who are not majoring in computer. It is open source and very small. Study well.

2. I: C language Embedded Linux engineers need to have oneThe basics of C language, C language is the most important and main programming language in the embedded field. Through a large number of programming examples, we focus on understanding the basic programming and advanced programming knowledge of C language.

3. Master the structure and principle of mainstream embedded microprocessors (preliminarily set as arm9) (2) Must master an embedded operating system (preliminarily set as uclinux or linux, version to be determined) (3) Must be familiar with the embedded software development process and do at least one An embedded software project.

4. Learning a single-chip microcomputer well can lay a good foundation for the adoption of embedded systems. 4 Linux basics The source code and architecture of Linux are open, and they are particularly widely used in embedded systems. Learning Linux will be of great help to the development of the system.

What basic knowledge is required for the development of embedded systems? Could you please teach me?

Embedded development requires professional knowledge, which is divided into two aspects: hardware and software! Hardware knowledge: Digital and analog electricity is the foundation, and you also need to know some signal processing, schematics, PCB circuit board design, etc., and more importantly, debugging experience.

No matter which direction you choose, you need to have basic linux knowledge. Other knowledge that needs to be mastered are ARM (the most commonly used embedded processor) and C language programming. The mastery of each aspect of knowledge ultimately determines the individual's embedded linux. The comprehensive ability of development.

What do embedded software engineers need to learn? Operating system: first install a vmware workstation on the computer, and then install a linux virtual machine in the vmware workstation. Learn the basic principles of the operating system, be familiar with the development environment in the Linux environment, and then slowly study and master it.

The characteristics of the embedded operating system that are not included in the following description are ___.

The system is streamlined. Embedded systems generally do not have a clear distinction between system software and application software, and do not require that their functional design and implementation are too complicated. This is conducive to the cost of the control system on the one hand, and also conducive to the realization of system security.(4) High real-time.

[Answer]: B In a broad sense, any dedicated software and hardware system with a microprocessor can be called an embedded system. In a narrow sense, embedded systems emphasize those independent systems composed of embedded microprocessors with their own operating systems and specific functions for specific occasions.

[Answer]: C In a broad sense, any dedicated software and hardware system with a microprocessor can be called an embedded system. In a narrow sense, an embedded system emphasizes an independent system with its own operating system and specific functions for specific occasions composed of embedded microprocessors.

1. Answer: A If the embedded system design and development process is divided into four stages: system requirements analysis and specification description, system design, component design, system integration and testing. Among the following statements, the appropriate one is ( ).

2. Be familiar with the composition of embedded system hardware and master the control technology of commonly used I/O interfaces and I/O devices. Familiar with the basic architecture of embedded system software, understand the function and structure of embedded operating system, the principle and application development of μC/OS-II.

3. For the preparation for the CET-3 exam, the Higher Education Press has published the National Computer Level Test Level 3 Course - Embedded System Development Technology (2018 edition). Just study this book.

4. The content of the computer level 3 embedded system development technology examination mainly includes the concept and basic knowledge of embedded system, embedded processor, embedded system hardware composition, embedded system software, embedded system development and other related knowledge and skills.

5. The textbook is the third-level examination of the National Computer Level Examination - Embedded System Development Technology, which is a third-level examination of the National Computer Level Examination.
