Embedded Systems

Developing the ability to program microcontrollers close to the hardware, understand how software interacts with processor memory and peripherals, and build reliable connections between code and physical components.

My current work begins with Embedded C and practical experimentation using the STM32F407G-DISC1. The planned path then progresses into ARM Cortex-M processor architecture and bare-metal peripheral-driver development.
