Bare-Metal Programming

This repository is dedicated to exploring bare-metal programming on embedded systems. It provides practical examples and guides to interact directly with hardware without relying on an operating system.

Getting Started

Introduction

Bare-metal programming is a low-level programming approach where software interacts directly with hardware without any intermediate operating system or framework. This repository contains step-by-step examples to help you get started with embedded development.

Current Example: Blinky for Nucleo-F429ZI

The repository currently includes a blinky example for the Nucleo-F429ZI board. The code demonstrates how to toggle an LED using basic GPIO configuration.

Why Bare-Metal Programming?

• Efficient Resource Use: Direct access to hardware allows for optimized performance.
• Learning Experience: Gain deeper insights into microcontroller architectures and peripherals.
• No OS Overhead: Write code without the complexity and limitations of an operating system.

Prerequisites

To run the examples, you need:

1. Toolchain: ARM GCC or other appropriate compiler for your platform.
2. IDE: You can use an IDE like VSCode, Eclipse, or simply a text editor.
3. Debugger/Flasher: ST-Link or similar hardware for programming the microcontroller.

How to Set Up the Environment

1. Install ARM GCC Toolchain: Follow the instructions on ARM GCC Toolchain to install the compiler.

2. Set Up Your IDE: You can choose your preferred development environment, such as:

   • VSCode with the Cortex-Debug extension.
   • Eclipse for embedded development.

3. Connect the Board: Make sure you have the Nucleo-F429ZI board connected via ST-Link or other compatible flashing tools.

4. Compile and Flash: Build the project and flash it onto the microcontroller using your chosen toolchain and debugger.

How to Use the Examples

1. Clone the Repository:

   git clone https://github.com/sonysunny0007/Bare-metal-STM32.git
   cd Bare-metal-STM32
