UART Programming in C (Building from Scratch) - Part 2 | Transmit & Receive Functions

Welcome to Part 2 of our UART Programming in C series! In this session, we build UART transmit and receive functions from scratch, deepening your understanding of how serial communication works in embedded systems.

💡 What you’ll learn in this video:

Writing UART transmit (UART_Tx) and receive (UART_Rx) functions manually

Understanding polling-based UART communication

Using registers to send and receive data

Code demonstration and explanation step-by-step

Tips for debugging UART communication

This tutorial will help you gain low-level mastery of UART implementation for microcontrollers like STM32, AVR, or 8051 using pure C code without libraries.

🔧 Perfect for students, hobbyists, and professionals working in embedded systems and microcontroller programming.
