Master Layered and Time‑Slice Design for Microcontroller Projects

This article explains how to apply layered architecture and time‑slice (time‑slot) design in microcontroller programming, using a keypad‑scanning example to illustrate hardware, driver, and application layers, and shows how RTC‑based interrupts can manage multiple concurrent timers efficiently.
