The implementation of a state machine consists of three elements: state, event, and response. When converted into specific behaviors, it can be summarized in three questions: What happened? What state is the system currently in? In this state, what should the system do when this event occurs? Implementing a state machine in C language can … Read more
In actual project development, projects are often developed in parallel, which means that hardware design, low-level software design, and application software design are carried out simultaneously. For example, debugging module drivers on development boards while debugging applications on other platforms and then porting them to the current platform, etc. This also involves how to improve … Read more
