One 、 Embedded difficulties
Embedded development is softer than the Internet （ such as Java Back end ） It's still harder , such as Java Development , Basically, it's all in user mode , But a lot of embedded things go deep into the kernel state .

Two 、 General learning ideas
On the whole , Embedded learning can be divided into three stages ：
First, the basic learning stage , This includes the basics of general programming （C Language 、 data structure / Algorithm 、 operating system 、 Network counting 、 Group counting 、Linux System basis ） And basic hardware foundation , Firmly grasp these two foundations , It is the power source of continuous development and progress .
The second is the embedded application programming stage , Or system platform programming phase . Because it usually depends on specific embedded platform and specific embedded operating system , Familiar with the programming method and process of this system platform . With the common ARM+Linux Platform as an example , Need to master from memory management to multitasking programming 、 file I/O、 Network programming , Even graphical interface programming and other major aspects .
Finally, we will go deep into the underlying development stage of embedded system , The most common are kernel development and driver development , These systems belong to the category of kernel state development , So we need to understand the internal mechanism of the operating system , On this basis, we need to master from system porting to kernel development 、 Every detail of driver development , This is the way to become a God .

The article is relatively long , More words , You can first open the avatar and pay attention to me , Then take your time ,/// Insert a ： At the beginning of this year, I recorded a set of systematic introductory single chip microcomputer tutorial , If you want, just ask me for it. It's free , I can send a private message ~ Click the black font in the lower left corner of my avatar and I can also get it . I've been relatively idle recently , Take me to finish the design , Take students to provincial or above competitions ///
