STM32 Practice ⚙️

A repository for storing and reviewing STM32 programming exercises completed during class.

This repository is mainly used as a personal study archive so that I can revisit the code and concepts later.

📚 Learning Topics

• GPIO
• UART
• UART communication between STM32 boards
• DMA
• Interrupts and callbacks
• Receive-to-Idle
• Input / output handling
• Buffers
• I2C
• STM32 HAL
• STM32CubeMX / STM32CubeIDE

💬 UART Communication Practice

Practice with serial communication using STM32 UART.

Topics include:

• PC ↔ STM32 UART communication
• STM32 ↔ STM32 communication
• TX / RX handling
• UART DMA reception
• HAL_UARTEx_RxEventCallback()
• Receive-to-Idle
• Input buffering
• Enter and Backspace handling

A simple message communication program was also implemented during class using two STM32 boards.

📁 Repository Structure

This repository contains STM32 exercises and code created during class using STM32CubeIDE and STM32 HAL.

🌱 Purpose

The purpose of this repository is to keep the code and exercises from class organized for review.

Rather than being a standalone project, it serves as a study archive for understanding STM32 peripherals, communication, and embedded programming concepts.
