Understanding Interrupt Priorities in Microcontrollers

Understanding Interrupt Priorities in Microcontrollers

The content of interrupt priorities includes general urgent interrupts and particularly urgent interrupts, which depend on the specific system design. This involves the concepts of interrupt priority and interrupt nesting. Today, we will briefly introduce the relevant registers without providing example code. The background of interrupts can be more complex in real life. For example, … Read more

1. Program Execution Methods Polling System Refers to a method where all hardware is initialized first during program execution, followed by a main program that runs in an infinite loop, executing required functions in sequence. The polling system is a simple and reliable method, generally suitable for situations where tasks need to be executed in … Read more
