STM32 UART Bare Metal | Hello, World! (Getting Started)

In this video, I demonstrate a bare-metal UART implementation on an STM32 microcontroller - no HAL or CubeMX. Using register-level programming, we initialize UART and transmit a simple "Hello, World!" message to a PC over a serial terminal. This isn't a deep dive into UART. Think of it as a preview of what's to come. My goal is to teach embedded systems from the ground up by working directly with the hardware, building the skills used by firmware and embedded engineers.
