Bare-Metal UART Driver
UART is the simplest form of communication protocol in embedded systems. Built on STM32F429I, I walked through every building process of bare-metal UART driver from scratch.

Project Overview
- Hardware: STM32F429I-DISC1
- IDE: STM32CubeIDE
- Key Topics: Clock configuration, GPIO alternate functions, USART registers, interrupt-driven TX/RX
Goals
This project covers building a UART driver without relying on HAL or any middleware — configuring every register by hand, from clock initialization to interrupt handling.
