Overview

Lcd2004 is a clean, lightweight library designed for interfacing with liquid crystal displays (LCDs). It offers a simple setup process and efficient memory usage, making it suitable for a wide range of embedded projects.

The library supports various display configurations and provides a flexible API to control LCD functions, including:

• text output;
• cursor management;
• custom character creation;
• display settings (on/off, cursor visibility, blinking);
• positioning and line breaks.

Key Features

• Ease of use: straightforward initialization and intuitive methods for common tasks.
• Memory efficiency: optimized to minimize resource usage on microcontrollers.
• Flexibility: supports both 8‑bit and 4‑bit communication modes.
• Customization: allows creation and use of custom characters.
• Compatibility: works with standard LCDs (e.g., 16×2, 20×4).
• Configurable behavior: numerous #define options let you tailor the library to your project’s needs (e.g., disabling unused features to save space).

Library Scope

Lcd2004 provides:

• a core Lcd2004 class with methods for display control;
• support for basic text output via Print class inheritance (optional);
• low‑level functions for direct command and data sending;
• optional buffering to reduce flicker and improve performance;
• compile‑time options to strip out unused functionality and reduce code size.

Target Audience

This library is ideal for:

• hobbyists and makers working with Arduino or similar platforms;
• developers seeking a lightweight LCD solution for resource‑constrained environments;
• educators and students looking for a clear, well‑documented library to learn display interfacing.
