Project Overview

This project aims to program an LCD1602 display using AVR-GCC for an Atmega328p microcontroller. The code is written in C/C++ and is designed to be cross-platform, ensuring compatibility with various operating systems.

Project Structure

The project is organized into several directories, each containing specific types of files:

/include

• avr_random_noise.h: Header file for the noise class.
• buttons.h: Header file for the buttons.
• customer_data.h: Header file containing customer data structures.
• lcd_display_option.h: Header file for LCD display options.
• set_Clock.h: Header file for the function to set time.
• special_functions.h: Header file for the functions triggered by buttons.
• timer.h: Header file for the internal timer.

/libs

• lcd.cpp: Source file for the LCD control functions.
• lcd.h: Header file for the LCD control functions.

/src

• avr_random_noise.cpp: Implementation of a random class listening to noise from the ADC.
• buttons.cpp: Implementation of the button functionality.
• customer_data.cpp: Implementation of customer data handling.
• lcd_display_options.cpp: Implementation of LCD display options.
• main.cpp: The main entry point for the program.
• set_Clock.cpp: Implementation of the ability to select the time.
• special_functions.cpp: Implements functions that can be triggered by buttons.
• timer.cpp: Implementation of the internal timer.

Root Directory

• Makefile: Contains commands to compile the project.
• README.md: This file, providing an overview and instructions.

How to Use

1. Ensure you have AVR-GCC installed on your system.
2. Clone the repository to your local machine.
3. Navigate to the root directory of the project.
4. Run make to compile the project.
5. After successful compilation, upload the binary to the Atmega328p microcontroller.
6. The LCD should display the programmed output upon successful upload.

Cross-Platform Compatibility

This project is designed to be cross-platform. It has been tested on Windows, macOS and archLinux through WSL2, but it should work on other systems where AVR-GCC is supported.
