The development of the embedded industry has become more and more popular with the explosion of smart hardware and the advent of the Internet of Things era, so that more people have seen the development prospects and want to enter the embedded development industry. However, the problem faced by many beginners is that they do not know where to start and the embedded learning route, which leads to confusion when learning. Below I will introduce to you the embedded learning route, I hope it can help you.
If you want to engage in embedded development, you need to understand a lot of technologies. A mature embedded engineer needs to understand application development, underlying development, etc.
Generally, if we want to learn embedded development, we must start from basic Linux, C language , data structure development, then to ARM, assembly, Linux kernel, driver, etc., and then through more project exercises to become a qualified embedded development engineer.
There are really a lot of things to learn about the embedded Internet of Things. Don’t learn the wrong route and content, which will cause your salary to go up!
will share an information package with you for free, which costs almost 150 gigabytes. The learning content, interviews, and projects are relatively new and comprehensive! It is estimated that buying a certain fish online will cost at least dozens of dollars.

Embedded learning method steps:
1. Basic knowledge:
Purpose: I can understand the working principle of hardware, but the focus is on embedded software, especially operating system level software, that will be my advantage.
subjects: digital circuits, computer composition principles, embedded microprocessor structure.
Assembly language, C/C++, compilation principles, discrete mathematics.
Data structures and algorithms, operating systems, software engineering, networks, databases.
Method: Although there are many subjects, they are all relatively simple basics, and most of them have been mastered. It is not necessary to take all the courses, but you can take electives according to your needs.
focuses on books: the c++ programming language (I haven’t had time to read it yet) and data structure-C2.
2. Learning linux:
Purpose: Master the linux system in depth.
method: use linux—>linxu system programming development—>driver development and analysis of linux kernel . Let’s take a deep look first, and then we’ll talk about the principles. After reading it several times, analyze the situation and compare it deeply. The two books are intertwined. Deepness is the outline and emotion is the purpose. Analysis is version 0.11, which is suitable for learning. Finally dive into the code.
focuses on books: complete analysis of the Linux kernel, advanced programming in the unix environment, in-depth understanding of the Linux kernel, scenario analysis and source generation.
3. Learn embedded linux:
Purpose: Master the embedded processor and its system.
(1) Embedded microprocessor structure and application: Just follow the arm principle and assembly directly, do not repeat x86.
(2) Embedded operating system category: ucOS/II is simple, open source, and available for entry. Then delve into uClinux.
(3) You must have a development board (arm9 or above), and you can participate in training if you have the conditions (you will make rapid progress and make some friends).
4. In-depth study:
A. Digital image compression technology: mainly you should master MPEG, mp3 and other encoding and decoding algorithms and technologies.
B, communication protocols and programming technologies: TCP/IP protocol, 802.11, Bluetooth, GPRS, GSM, CDMA, etc.
