The microcontroller processing mode given in this article is a development mode based on a single task and without an operating system. Many engineers who have just started have certainly not had the opportunity to learn and master the operating system development mode of multi-tasking. However, before using and learning multi-tasking operating system development, we still need a development mode that can be similar to a multi-tasking operating system to some extent and can achieve a time slice polling execution mode in a certain sense. This is very helpful for future contact with multi-tasking operating system development.
Of course, the development model mentioned in this article is already used by many engineers in the industry, and they use it better and more skillfully than I do. However, many students who have just graduated or have not yet graduated have no chance to see this processing model. There is no book that currently provides a complete architecture of how to write system code. Therefore, I believe this article will be very helpful for beginners and students. As for those experts, you are welcome to give your opinions, and please just laugh at the shortcomings of this article.
