lvgl — Light and Versatile Graphics Library for Embedded UIs

Overview

LVGL is a mature and well-known open-source graphics library designed for creating beautiful user interfaces on embedded systems. It supports a wide range of display types and microcontrollers, offering a rich set of features to build modern and responsive GUIs. LVGL stands out for its low memory footprint, extensive widget library, and support for multiple languages and input devices.

Key Features

Supports various display types including monochrome, ePaper, OLED, and TFT displays
30+ built-in widgets for creating complex UIs
Flexible style system with ~100 style properties
Responsive layouts using Flexbox and Grid layout engines
UTF-8 text rendering with support for CJK, Thai, Hindi, Arabic, and Persian writing systems

Use Cases

Developing user interfaces for IoT devices and smart home appliances
Creating UIs for industrial control panels and medical equipment
Designing interfaces for wearable devices like smartwatches and fitness trackers

Advantages

Low memory usage, requiring only 32kB RAM and 128kB Flash
Portable and compatible with any MCU or MPU, with or without an OS
Supports multiple displays and various input devices
Extensive documentation and community support

Limitations / Considerations

May require additional buffer memory for rendering, depending on the screen size
Customization and advanced features might increase the memory footprint
Learning curve for new developers due to the extensive feature set

Qt for Embedded Systems: A comprehensive C++ framework for UI development, known for its rich set of tools and libraries. Qt is more resource-intensive compared to LVGL.
Mbed UI: A lightweight UI library designed specifically for ARM Cortex-M microcontrollers. It is less feature-rich than LVGL but optimized for low-power devices.
TouchGFX: A full-featured UI development framework that provides a high-level API for creating sophisticated UIs. It is more complex and has a steeper learning curve than LVGL.
