This project demonstrates the development of a modular and reusable GPIO driver using register-level programming in Embedded C. The design follows a layered approach where hardware-specific details are abstracted through a clean driver interface. (STM32 + Keil Simulation)

Mixed-signal multi-layer PCB designed in Altium with STM32 microcontrollers, Ethernet PHY, DAC/ADC, motor drivers, and audio circuitry. Supports USB, I²C, UART, CAN, I²S, and MII/RMII.

STM32 peripherals configuration and driver development using the Hardware Abstraction Layer (HAL) API. These approaches can be used in most ARM Cortex-M Microcontrollers regardless of the semiconductor vendors and brands (though they might need some tweaks!)

Super simple gpio blink driver which I'm using to understand how abstraction layers works in mcu firmware development. I have first used the HAL's stm32 code and reference manual and datasheet and then created it by my own criteria.
