LVGL GUI Development: A Comprehensive Overview

Graphical user interfaces (GUIs) are becoming more and more important in embedded devices – from home appliances to medical equipment – to provide user friendly experience. But developing a rich GUI on resource constrained hardware is hard. LVGL (Light and Versatile Graphics Library) is a popular solution: it’s free, open-source graphics framework for microcontrollers and embedded systems.

As specialists in embedded systems development, we are always looking for the best solutions for rapid development. In this article we will take a closer look at LVGL, its architecture, features and benefits to help you choose the right tool for your embedded projects.

 

LVGL at a Glance: Architecture & Features

Lightweight C Library

LVGL is a C library for embedded use. It has minimal hardware requirements, runs on 16-, 32- or 64-bit MCUs clocked ≥ 64 MHz and uses only tens of kilobytes of memory (about 48 KB RAM and 100 KB flash for a simple GUI). LVGL works with any MCU/MPU, any high quality display, any OS or even bare-metal environment. It supports common display types (TFT displays, OLED, ePaper, etc.) and color formats.

 

Modular Architecture

At the core LVGL provides a GUI rendering engine and an object hierarchy for UI elements (called “widgets”). Developers create UI objects (buttons, labels, sliders, etc.) and LVGL manages their rendering, input handling and animations. LVGL uses a relative layout system inspired by web/CSS paradigm – including flexbox and grid layouts – so widgets can position and size themselves automatically.

 

Rich Set of Widgets and Drawing Features

Despite its small footprint LVGL has a comprehensive set of GUI capabilities:

 

• UI Widgets: LVGL comes with 30+ built-in widgets – labels, buttons, sliders, progress bars, checkboxes, switches, charts, tables, text areas, keyboards, message boxes and more.

 

• Advanced 2D Graphics: LVGL’s software rendering engine supports modern visual effects while being efficient. It draws shapes with anti-aliasing for smooth edges and supports features like gradients (linear, radial, conical), transparency, shadows and image transformations

 

• Styling and Theming: Every widget in LVGL is highly customizable via a style system. There are over 100 style properties (colors, padding, borders, etc.) which can be applied to any object or its parts (for example, a slider has stylable parts for its knob, indicator and track). Styles can change automatically based on state (pressed, focused, disabled, etc.) and you can animate style changes with transitions.

 

• Internationalization: LVGL was built with global use in mind. It uses UTF-8 encoding and supports complex text rendering, including right-to-left scripts (Arabic, Persian, Hebrew) and CJK font characters. LVGL can support many languages and locales easily – you can even mix LTR and RTL text in one interface.

 

• Input Handling: Besides touchscreen input, LVGL abstracts input devices so you can use buttons, rotary encoders, keypads or other inputs as GUI controls.

 

• Multi-Display and Custom Drivers: LVGL supports multiple displays (for devices that have more than one screen output) and even off-screen rendering, making it ideal for commercial projects that require versatile setup, connection and configuration options.

 
 

LVGL library for Embedded GUI Development

LVGL has several advantages for embedded GUI development, making it a popular choice for many teams:

 

1. Small Footprint & High Performance: 
   LVGL is optimized for resource-constrained systems, uses only a few kilobytes of RAM and flash memory, and provides smooth, smartphone-like interfaces. Its C code rendering engine ensures high performance even on low-power devices. LVGL can run on MCUs with minimal resources and still achieve high frame rates, perfect for battery-powered devices like wearables.

 

2. Comprehensive Feature Set: 
   Despite its small footprint, LVGL has a wide range of features such as widgets, animations, advanced 2D drawing, input handling and multitouch gestures. These features allow developers to create beautiful UIs with minimal custom code. LVGL competes with many proprietary GUI solutions, enables sophisticated interfaces even on devices with limited resources.

 

3. Hardware and OS Flexibility: 
   LVGL is very flexible, supports many hardware and operating systems. This platform independence allows teams to use LVGL on different hardware (e.g. STM32, NXP, Espressif, etc.) and operating systems, on bare-metal MCUs or Linux-capable MPUs. LVGL’s Windows simulator allows developers to test and develop their GUI without the actual hardware, providing more flexibility and less development risks.

 

4. Open Source with Active Community: 
   LVGL is open-source under the MIT license, no licensing fees or royalties required, which saves a lot of money compared to commercial GUI libraries. The growing and active community provides continuous support, updates and bug fixes. The transparency of open source allows developers to debug and customize LVGL to their needs. Large companies like Xiaomi use LVGL for their smart products, which contributes to the ongoing development.

 

5. Customization and Control: 
   LVGL gives developers full control over the GUI. The library is close to the hardware and written in C, so you have fine-grained control and easy integration with the system. Custom widgets and drawing routines can be added as needed, making LVGL very adaptable, especially for complex or safety-critical systems.

 

6. Cost Effective and Commercial Friendly: 
   LVGL’s MIT license means no hidden costs or royalties, it’s very cost-effective. Companies can avoid expensive commercial licenses, simplify compliance. Formal support is available if needed, but it’s optional, so you have the flexibility to choose the level of support you need.

 
 

Limitations

No framework is perfect – it’s important to also consider LVGL’s limitations and the challenges of using it, to make an informed decision.

One of the main challenges is the lack of a native GUI builder tool. Unlike some commercial alternatives, LVGL doesn’t have a drag-and-drop design tool (only LVGL editor XML-Based). Designing interfaces typically involves writing C code or using third-party tools like SquareLine Studio or GUI Guider. While this approach provides more flexibility, it’s more coding-heavy and might be a challenge for teams that have UI designers or prefer visual tools. Additionally, LVGL can have a steeper learning curve for UX/UI designers. Since the tool doesn’t support the import of graphical designs from programs like Photoshop or Sketch, developers must implement the designs in code. This can create friction in larger teams, especially where designers aren’t coding. But once familiar with LVGL’s API, developers often find it’s not that bad.

Another consideration is the limited official support and warranty. LVGL is an open-source project with no vendor support or commercial guarantees. While the community provides valuable resources, teams that need formal support or SLAs might find this a drawback compared to commercial solutions like Qt for MCUs or Embedded Wizard. But the community and third-party consultants can help mitigate this.

The niche ecosystem of LVGL means there are fewer third-party extensions and integrations than with bigger frameworks like Qt. While it has a lot of built-in features, teams might need to invest time in custom solutions for more specific needs, as the community and available resources are smaller.

Moreover, LVGL is primarily a GUI toolkit, so other essential application functions like networking, file systems or threading utilities must be handled by separate libraries or the OS. This is typical for embedded systems, but teams should be aware that LVGL only focuses on the GUI aspect.

In terms of performance tuning, while LVGL is very efficient, achieving optimal performance on constrained hardware might require some low-level adjustments. For example, developers might need to profile rendering and fine-tune memory usage to avoid issues like flicker or excessive CPU usage, especially when using advanced visual effects or even monitors in the interface. This is an area where commercial solutions might have an advantage, with built-in optimizations for the target hardware.

Finally, manual memory management can be a challenge for teams used to higher-level frameworks with garbage collection. LVGL requires developers to manage memory manually, which can be an adjustment for those coming from more abstracted environments. Deleting UI objects and screens properly is critical for memory management.

 
 

Framework Comparison: TouchGFX, Qt for MCUs, Embedded Wizard

LVGL is not the only player in embedded GUIs. Other popular frameworks are TouchGFX, Qt for MCUs, and Embedded Wizard. Each has its own approach and might be better or worse fit for the project. Below is a brief comparison of these frameworks vs LVGL:

Feature	LVGL	TouchGFX	Qt for MCUs	Embedded Wizard
License	Free (open-source)	Proprietary (free for STM32)	Commercial	Commercial
Open Source	Yes	No	No	No
Target Audience	General embedded systems	STM32 users	General embedded systems (Qt users)	General embedded systems
Ease of Use	Moderate (manual coding)	High (WYSIWYG GUI editor)	High (QML-based UI design)	High (WYSIWYG GUI editor)
Customizability	High (full control over code)	Moderate (limited customizability)	Low (less flexibility compared to LVGL)	Moderate (limited control over generated code)
Hardware Support	Wide range of MCUs	STM32 microcontrollers	Selected MCU families (STM32, NXP, Renesas)	Wide range of MCU families
Performance	High (lightweight, optimized)	High (optimized for STM32 hardware)	Moderate (higher resource usage)	High (optimized for low footprint)
Development Tools	Manual coding (no visual editor)	GUI designer (TouchGFX Designer)	Qt Design Studio, QML, Qt Quick Ultralite	WYSIWYG editor, Chora language
Cost	Free	Free with STM32, commercial use requires ST license	Commercial license required	Commercial license required

In summary, here’s an objective snapshot of these frameworks:

 

• LVGL is open-source, super portable and low-cost, but requires more coding and self-support;
• TouchGFX is free and user-friendly for STM32 users with its designer, but locks you into ST’s ecosystem and a closed library;
• Qt for MCUs offers a modern UI paradigm and strong tools, but at the cost of licensing fees and higher resource usage;
• Embedded Wizard provides a polished GUI development experience with broad hardware support, but it’s a proprietary solution requiring investment.

The choice depends on your project constraints – e.g. which microcontroller you use, your team’s skill set, UI complexity and budget for tools. Many vendors (like NXP, ST, Renesas) actually support multiple of these frameworks in their SDKs, because each has its niche. The good news is that LVGL often is the flexible choice if you want to stay vendor-neutral and cost-efficient, as long as you’re willing to code the GUI yourself.

 

Use Cases for LVGL Graphics Library

LVGL’s versatility makes it suitable for a wide range of industries. In medical devices, it powers interfaces in devices like blood glucose monitors, heart rate monitors, and ventilators, providing crisp graphics and real-time data display on resource-constrained systems. Its open-source nature is beneficial in regulated industries like healthcare, avoiding licensing issues.

In industrial automation, LVGL is used in HMIs for factory control panels, PLC screens, and CNC machines. Its low resource usage and deterministic behavior make it ideal for real-time, high-reliability applications. LVGL’s ability to customize UIs is especially valued in the industrial sector, where branded, unique interfaces are needed.

For consumer electronics and wearables, LVGL powers smartwatches, fitness trackers, and home appliances. Its skinnable UI and low overhead make it a great choice for creating modern interfaces with smooth animations, even on cost-effective hardware.

In the automotive sector, LVGL supports automotive displays, infotainment systems, and digital instrument clusters, thanks to its fast boot time and low overhead. It’s used in embedded displays in vehicles, providing reliable graphics for navigation, climate control, and more.

Overall, LVGL is a flexible solution for embedded GUI tasks across various industries, excelling in performance, reliability, and customizability for 2D-based applications.

 

LVGL Code Example for Graphical User Interfaces

In this example, we’ll create a basic smart home control panel using LVGL. The interface will feature a temperature display button and a slider. The slider will allow the user to adjust the house temperature, and the button will dynamically reflect the current temperature setting.

Since LVGL is primarily designed for embedded systems, I ran this example using the LVGL Windows simulator. This allows the LVGL application to run directly on my Windows machine, making it easy to develop, test, and record the interface without needing actual embedded hardware.

This setup is ideal for prototyping and creating demos like the one.

 
 

Main Row and background

We begin by customizing the screen’s appearance and preparing the layout that will hold our smart home controls.

1. Clear default styles and set a dark background 
We remove all existing styles from the active screen and apply a dark gray background with full opacity:

 

lv_obj_remove_style_all(lv_scr_act());
lv_obj_set_style_bg_color(lv_scr_act(), lv_color_hex(0x161616), 0);
lv_obj_set_style_bg_opa(lv_scr_act(), LV_OPA_COVER, 0);

2. Create a horizontal container (main row) 
Next, we create a full-screen container to hold the button and slider. This container uses LVGL’s flex layout with horizontal flow and spacing between elements:

 

lv_obj_t *main_row = lv_obj_create(lv_scr_act());
lv_obj_remove_style_all(main_row);
lv_obj_set_size(main_row, LV_PCT(100), LV_PCT(100));
lv_obj_set_flex_flow(main_row, LV_FLEX_FLOW_ROW);
lv_obj_set_style_pad_column(main_row, 15, 0); // 15 pixels spacing between children
lv_obj_set_style_bg_opa(main_row, LV_OPA_TRANSP, 0);

// Add margins:
lv_obj_set_style_pad_top(main_row, 30, 0);   // 30 pixels top margin
lv_obj_set_style_pad_left(main_row, 30, 0);  // 30 pixels left margin

 lv_obj_align(main_row, LV_ALIGN_CENTER, 0, 0);

This main_row will serve as the base layout, arranging our temperature button and slider side by side.

 

Button

Now we add a button to the left side of our smart home panel. This button will display the current temperature and respond to click events.

1. Create the button and apply custom styles 
We add a child object to main_row, remove its default style, and size it to 300×300 pixels. The background is styled with a dark gray color (#404040), full opacity, and slightly rounded corners:

 

button = lv_obj_create(main_row);
lv_obj_remove_style_all(button);
lv_obj_set_size(button, 300, 300);
lv_obj_set_style_bg_color(button, lv_color_hex(0x404040), 0);
lv_obj_set_style_bg_opa(button, LV_OPA_COVER, 0);
lv_obj_set_style_radius(button, 8, 0);
lv_obj_align(button, LV_ALIGN_CENTER, 0, 0);

2. Add click interaction 
We register a callback function (more on that later) to handle click events on the button:

 

lv_obj_add_event_cb(button, button_event_cb, LV_EVENT_CLICKED, NULL);

3. Add and style the temperature label 
Inside the button, we place a label to display the current temperature. It’s centered and styled with a light gray color (#BBBBBB):

 

g_temp_label = lv_label_create(button);
lv_label_set_text_fmt(g_temp_label, "Temperature: %d°C", temperature);
lv_obj_set_style_text_color(g_temp_label, lv_color_hex(0xBBBBBB), 0);
 lv_obj_center(g_temp_label);

This button serves as a dynamic temperature display and interactive element within the panel.

 

Slider

Next, we add a vertical slider to the right side of the row layout. This slider allows the user to adjust the temperature, and a label on the slider will show its current value in real-time.

1. Create the slider and define its size and range 
The slider is added as a child to main_row, stripped of default styles, and sized to 50×300 pixels. It’s centered vertically and configured to allow values between 0°C and 30°C, initially set to 13°C:

 

lv_obj_t *slider = lv_slider_create(main_row);
lv_obj_remove_style_all(slider);
lv_obj_set_size(slider, 50, 300);
lv_obj_align(slider, LV_ALIGN_CENTER, 0, 0);
lv_slider_set_range(slider, 0, 30);
lv_slider_set_value(slider, 13, LV_ANIM_OFF);

2. Style the main slider track 
The base (main part) of the slider is styled with a dark gray color (#444444), full opacity, and a large corner radius for a rounded look:

 

lv_obj_set_style_bg_color(slider, lv_color_hex(0x444444), LV_PART_MAIN);
lv_obj_set_style_bg_opa(slider, LV_OPA_COVER, LV_PART_MAIN);
lv_obj_set_style_radius(slider, 50, LV_PART_MAIN);

3. Style the slider’s indicator (filled part) 
The indicator part shows how much of the slider is filled. It’s styled in red (#FF0000) with full opacity and a smaller radius for contrast:

 

lv_obj_set_style_bg_color(slider, lv_color_hex(0xFF0000), LV_PART_INDICATOR);
lv_obj_set_style_bg_opa(slider, LV_OPA_COVER, LV_PART_INDICATOR);
lv_obj_set_style_radius(slider, 10, LV_PART_INDICATOR);

4. Add a dynamic value label 
A label is created inside the slider to display the current value (e.g., “13°C”). It is centered and styled in white text for visibility:

 

    lv_obj_t *slider_val_label = lv_label_create(slider);
    lv_label_set_text_fmt(slider_val_label, "%d°C", 13);
    lv_obj_set_style_text_color(slider_val_label, lv_color_white(), 0);
    lv_obj_align(slider_val_label, LV_ALIGN_CENTER, 0, 0);

We also attach the label to the slider using lv_obj_set_user_data() so that it can be updated dynamically in the event callback.

5. Handle value changes 
Finally, we register an event callback for when the slider value changes. This callback can update the temperature and label text:

 

lv_obj_set_user_data(slider, slider_val_label);
lv_obj_add_event_cb(slider, slider_event_cb, LV_EVENT_VALUE_CHANGED, NULL);

 

Button callback

The button_event_cb function handles click events for the temperature button. When the button is clicked, it toggles an internal selected flag to keep track of whether the button is currently active or not.

Visually, this selection is represented by a red border around the button. If the button is selected, a 4-pixel red border is added to highlight it. If it’s clicked again and deselected, the border is removed, and the button returns to its original gray appearance.

 

static void button_event_cb(lv_event_t *e)
{
    selected = !selected;

    if (selected)
    {        
        lv_obj_set_style_border_width(button, 4, 0);
        lv_obj_set_style_border_color(button, lv_color_hex(0xFF0000), 0);
        lv_obj_set_style_border_opa(button, LV_OPA_COVER, 0);
    }
    else
    {
        lv_obj_set_style_border_width(button, 0, 0);
        lv_obj_set_style_bg_color(button, lv_color_hex(0x404040), 0);
        lv_obj_set_style_bg_opa(button, LV_OPA_COVER, 0);
    }
}

 

Slider callback

The slider_event_cb function handles value change events from the temperature slider. Whenever the user moves the slider, this callback is triggered.

Inside the callback, we first check that the event is of type LV_EVENT_VALUE_CHANGED — meaning the slider’s value was adjusted. We then retrieve the new value from the slider and update two labels:

 

• The label on the slider itself (centered visually on the slider) is updated to reflect the current temperature, showing something like “17°C” as the user drags the handle.
• The main temperature label on the button is also updated to show the same value, ensuring consistency between the two UI elements.

This allows the slider to provide immediate feedback to the user both locally and in the broader interface, creating a responsive and intuitive temperature control experience.

 

static void slider_event_cb(lv_event_t *e)
{
    if (lv_event_get_code(e) == LV_EVENT_VALUE_CHANGED)
    {
        lv_obj_t *slider = lv_event_get_target(e);
        lv_obj_t *slider_val_label = (lv_obj_t *)lv_obj_get_user_data(slider);
        int val = lv_slider_get_value(slider);

        if (slider_val_label)
        {
            lv_label_set_text_fmt(slider_val_label, "%d°C", val);
        }

        if (g_temp_label)
        {
            lv_label_set_text_fmt(g_temp_label, "Temperature: %d°C", val);
        }
    }
}

Results and takeaways

This simple smart home panel demonstrates how quickly you can build clean, responsive interfaces using LVGL. With just a few lines of code, we created a modern-looking layout featuring real-time interaction between UI elements — a temperature button that reacts to user input and a slider that updates display values instantly.

 
 

This example is a great starting point for more advanced smart home interfaces, dashboards, or embedded applications. Whether you’re building controls for HVAC, lighting, or appliances, LVGL gives you the tools to make it intuitive and visually appealing.

 

Conclusion & Further Resources

In conclusion, LVGL is a powerful tool to get polished GUIs on small microcontrollers. The world of embedded GUI development is big and getting bigger – and whatever you choose, LVGL or another framework, the goal remains the same: to create an interface that delights users and meets the technical constraints of your device.

When choosing a GUI framework, consider not just the library itself but the bigger picture: your product requirements, your team’s expertise and long-term maintainability. Some companies opt to partner with GUI development companies to help with this decision. Working with developers who have deep experience in frameworks like Qt and LVGL can give you an objective view on what fits your project’s needs. Such partners can accelerate development and ensure the chosen technology is used optimally – whether it’s LVGL or another solution – without a hard bias towards any single tool. In Scythe Studio we have a GUI-focused development team and we found that a careful upfront evaluation saves a lot of time later. By leveraging the right expertise, you can make the right choice and implement the GUI framework that will deliver a great user experience for your embedded product.

If you’re interested in exploring LVGL further, here are some useful resources: the official LVGL documentation and tutorials (available on docs.lvgl.io) provide in-depth guides on everything from basic widget creation to advanced customizations. The LVGL GitHub repo contains a wealth of LVGL examples and a simulator project to try out. There’s also an active forum (forum.lvgl.io) where you can ask questions and see how others solved similar problems.
