UART Programming in C (Using ST Headerfile) | STM32 UART Communication Tutorial

In this video, you’ll learn how to program UART communication on STM32 microcontrollers using ST-provided header files (without relying on HAL or CubeMX-generated code). This tutorial focuses on register-level UART configuration using CMSIS and standard peripheral header files for STM32F4 series.

💡 What you’ll learn:

Basics of UART protocol and serial communication

How to configure UART registers using ST's header files

Sending and receiving data over USART (polling method)

Writing custom functions for UART transmission and reception

Tips on debugging UART in STM32

📘 This approach gives you better control over low-level configuration and is ideal for performance-critical embedded applications.
