STM32 and Embedded C Programming Coursework

This repository contains my practical coursework, code exercises, and peripheral drivers developed during the Microcontroller Embedded C Programming: Absolute Beginners course by FastBit Embedded Brain Academy (Kiran Nayak).

All target projects were written and tested using STM32CubeIDE targeting ARM Cortex-M microcontrollers.

Repository Structure

The workspace is organized into two main directories:

• /host

• Core C programming exercises executed directly on the host computer.

• Covers fundamentals such as data structures, pointers, bitwise operations, memory layout, and standard input/output.

• /target

• Firmware code designed to run directly on STM32 microcontroller hardware.

• Focuses on peripheral register manipulation, driver development, interrupt handling, and direct hardware interfacing.

Tools and Technologies

• IDE: STM32CubeIDE
• Language: Embedded C
• Target Hardware: STM32 Nucleo Development Board (ARM Cortex-M)
• Compiler / Toolchain: GNU Toolchain for STM32 (GCC)
• Debugging Tools: ST-LINK / OpenOCD

---

Key Topics Covered

• Embedded C Fundamentals: Data types, structure padding and packing, and type qualifiers like volatile and const.
• Pointers and Memory: Pointer arithmetic, type casting, memory mapping, stack and heap layout, and memory management.
• Bitwise Operations: Setting, clearing, toggling, and testing specific bits using bit masks and bit-fields.
• Microcontroller Architecture: Memory organization, bus matrix layout, peripheral base addresses, and register offsets.
• Low-Level Drivers: Writing register-level drivers directly without relying solely on abstraction libraries.
• Build Systems: Compilation flow, preprocessor directives, linker scripts, and understanding executable ELF files.

How to Run the Projects

1. Clone the Repository:

git clone https://github.com/YOUR-USERNAME/STM32-Embedded-C-Coursework.git

2. Import into STM32CubeIDE:

• Open STM32CubeIDE.
• Navigate to File > Import > General > Existing Projects into Workspace.
• Choose the host or target directory and import the project you want to run.

3. Build and Flash (Target Projects):

• Connect your STM32 Nucleo board via USB.
• Right-click the project folder and select Build Project.
• Select Run As > STM32 C/C++ Application to flash the code onto the board.
