# LCD-1602

C library for interfacing a **16×2 character LCD (HD44780-compatible)** with AVR microcontrollers.

This project provides a **modular and reusable driver** for displaying text on LCD-1602 modules using low-level GPIO control.

---

## Overview

The LCD-1602 library simplifies working with character LCD displays by abstracting
the low-level command timing and data transfer required by the HD44780 controller.

The code is written with **clarity and portability** in mind and can be easily integrated
into embedded projects using ATmega microcontrollers.

---

## Features

- 4-bit LCD interface
- Low-level command and data handling
- Character and string display support
- Clear display and cursor positioning
- Modular design for easy reuse

---

## Hardware / Environment

- **Microcontroller:** ATmega328P  
- **Development environment:** Atmel Studio  
- **Display:** LCD 16×2 (HD44780-compatible)
