This project involves the development of a comprehensive system for the STM32 "blue pill" ARM Cortex-M3 microcontroller, starting from ground zero. All aspects, including hardware initialization, peripheral configuration, and application logic, are crafted directly without reliance on pre-existing software frameworks or libraries.
- GPIO (General Purpose Input/Output): Used for interfacing with external components such as buttons and switches.
- LCD 2x16 Display: Provides a visual interface for users to interact with the timer.
- External Interrupt: Enables interrupt-driven handling of user input for actions like starting, pausing, and resetting the timer.
- System Timer (Systick): Provides a system-wide timer for precise timing operations.
The main.c file serves as the application layer, orchestrating the interaction between various drivers and functionalities to implement the desired chess timer behavior.
