How to Optimize Microcontroller Program Code?

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

Microcontroller Interrupt System and Timer/Counter

The interrupt system and timer/counter of a microcontroller are core modules for implementing real-time tasks and multitasking. 1. Interrupt System 1.
