# Triple Bootloader

-- Arduino Uno bootloader in C, C++, and assembly

This project implements a complete Arduino Uno bootloader in C, C++, and assembly. The bootloader is       responsible for loading the main program into the microcontroller's flash memory and starting its execution.

## Project Structure

- /triple-bootloader

- ├── src

- │   ├── main.c

- │   ├── main.cpp

- │   ├── bootloader.asm

- ├── Makefile

- ├── README.md

## Building the Project

To build the project, make sure you have the AVR-GCC toolchain installed. Then, run the following command:

```make```

This will generate three hex files:

- `bootloader_c.hex`: C implementation

- `bootloader_cpp.hex`: C++ implementation

- `bootloader_asm.hex`: Assembly implementation

## Cleaning the Project

To clean the build artifacts, run:

```make clean```

## Implementation Details

The bootloader is implemented in three different languages:

1. C (`src/main.c`)

2. C++ (`src/main.cpp`)

3. Assembly (`src/bootloader.asm`)

Each implementation provides the same functionality, demonstrating different approaches to creating an Arduino Uno bootloader.
