STM32 Learning Journey

Learning STM32 and Embedded Systems from scratch using C and STM32 microcontrollers.

This repository documents my hands-on learning journey in:

• Embedded C
• STM32 peripherals
• Register-level understanding
• Bare-metal programming concepts
• Debugging and problem-solving

Goals

• Build strong foundations in Embedded Systems
• Understand how hardware interacts with software
• Learn low-level programming concepts deeply
• Practice writing efficient and readable embedded C code

Learning Path

My STM32 learning journey will follow:

Phase 1: Basics

• What is STM32
• What is embedded system
• LED blinking (HAL library)

Phase 2: GPIO Deep Understanding

• Input/output pins
• Button handling
• Real hardware interaction

Phase 3: Communication

• UART (serial communication)
• SPI
• I2C

Phase 4: Advanced

• Timers
• Interrupts
• Memory concepts
• Register-level programming

• docs/01_Fundamentals/ contains concept notes and theory writeups.
• projects/LED_ON_stm32/ contains the STM32CubeIDE project files, source code, drivers, linker scripts, and build output folder.

This repository is part of my self-taught embedded systems learning journey. I focus on understanding concepts deeply rather than rushing through tutorials.
