Optimizing microcontroller programs usually refers to optimizing program code or execution speed. Optimizing code and optimizing speed are actually a unified contradiction. Generally, optimizing the size of the code will lead to an increase in execution time; if the execution speed of the program is optimized, it usually results in an increase in code size. … Read more
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
