LVGL Desktop Simulator - Quickly prototype LVGL UI

My projects
1

Hello so recently i have struggled to find a quick and easy way of testing LVGL on desktop so i’ve built an open-source desktop simulator for LVGL that allows developers to prototype and test embedded user interfaces directly on Windows or Linux, without requiring physical hardware.

live_preview_demonstration

What is it?

LVGL Desktop Simulator provides a desktop environment for running LVGL applications with:

  • LVGL display integration
  • Mouse and keyboard input
  • GLFW-based window management
  • CMake build configuration
  • helper scripts
  • “Live preview” workflow (Quickly recompile and reopen the window)

The project is organized into separate application, LVGL integration, platform, and configuration layers.

Technology stack

  • C and C++
  • LVGL
  • GLFW
  • CMake
  • Windows and Linux (Its been more tested on linux)

Repository

The repository includes build instructions, configuration files and documentation so everything you need to use it.

I would really appreciate feedback from the LVGL community.

Hi @Yuri_Alves_Bordin ,

Thank you for this contribuition.

The LVGL already have a simulator, did you have the chance to use? And yes, what’s the advance of you project compared to the LVGL Simulator?

Hi, yes, I’m familiar with these simulators. The main differences:

  • My live preview script automatic rebuild and relaunch when any file save so you see changes immediately without manually rebuilding

  • Standalone release packaging script - produces a distributable .tar.gz / .zip with the stand-alone binary, ready to share with a client so they can experiment, no toolchain required on their end

  • Screen shape fidelity - circular and rounded displays are previewed exactly as they’ll appear on hardware, via an OpenGL mask

I think using the acripts is what makes the most of my project for new users, making it really easy to clone and start making your UI out of the box, but if you already using any others simulators and don’t need any of these things i mentioned then using any of the simulator options would be fine.
