The interrupt system and timer/counter of a microcontroller are core modules for implementing real-time tasks and multitasking. 1. Interrupt System 1. Basic Concepts Interrupt: When a specific event (interrupt source) occurs, the CPU pauses the current task and executes the Interrupt Service Routine (ISR). After completion, it resumes the original task. Function: Improves CPU efficiency, … Read more
Today, let’s discuss a seemingly simple yet powerful technology that can solve complex problems—the microcontroller interrupt system.In automated production lines, it is often necessary to respond in real-time to multiple sensor signals. How can a small microcontroller accomplish this task? The interrupt system acts as the invisible “master scheduler”. What is an Interrupt System? Imagine … Read more
