A multi-tasking mechanism and application based on C51

Introduction 　　Traditional microcontroller programs generally use a single-task mechanism. Single-task systems have the advantages of being simple, intuitive, and easy to control. However, since the program can only be executed in sequence and lacks flexibility, interrupt functions can only be used to process some sh

Looking back at the previous programming tutorials, the first one is the I/O chapter. I/O mainly explains the pin characteristics of I/O and how to control the level input and output of I/O through C51; the second one is the interrupt chapter. The interrupt chapter introduces the necessity of the interrupt system and
