Let me also talk about my experience in getting started with embedded systems[Copy link]
I keep seeing people posting in forums asking how to get started with learning embedded systems. Personally, I think it depends on personal interest, whether you want to develop in the direction of software or hardware. If you want to develop in the direction of software, I suggest you first look at C. Note that this does not refer to the syntax level. I believe that there are generally no problems with the basic C language syntax. What is more important is how the C compiler works, how various resources are allocated after a program is compiled, how the stack is allocated, how the connector works, etc. Because embedded systems deal directly with hardware, you need to understand where the program you write is placed in the memory, where the various variables are placed at runtime, where the stack is placed, and how much stack is used. It is recommended that you have time to read the compilation principle, OS principles are also a must-read, but don't try to learn LINUX right away. To be honest, this is not very realistic. LINUX is too big. You can first learn some principles, such as what a real-time OS is, what process scheduling algorithms are, what a file system is, etc. Then find a small OS to play with, such as UCOSII, and then learn LINUX. If you are going for a hard direction, you must learn digital electronics well. Of course, it is best to learn CPLD/FPGA, which is also very useful in embedded systems. In addition, you must learn to analyze timing and read datasheets, otherwise you will be very depressed when facing the timing diagrams of various devices and hundreds of pages of E-text datasheets.

I strongly agree with this:) C++, C#, Java, etc. are all empty shells. Only by learning C well can you understand how the computer works inside. If you don't understand this, no matter how many languages you learn, it's like building a building on the beach. It will eventually become shattered due to the "pressure difference".
It's about C language!

For those of us who are engaged in embedded system development, we must be good at C language so that we can write good programs! [ This post was last edited by daicheng on 2009-8-19 16:39]
Most of the programming in JAVA and C# is to call the existing class library. For example, C# is nothing without .net framework. However, everything in C needs to be done by yourself, and even some assembly is embedded to realize some low-level operations. A person who is not familiar with how the computer works at the bottom level can never become an expert.
As long as you persist, you will eventually learn it. But technology is not valued in China, and bosses also want to make quick money. If you have connections, you can make a lot of money, and if you don't have connections, you can make a small amount of money.
