Simulator project for LVGL embedded GUI Library

The LVGL is written mainly for microcontrollers and embedded systems however you can run the library on your PC as well without any embedded hardware. The code written on PC can be simply copied when your are using an embedded system.

Using a PC simulator instead of an embedded hardware has several advantages:

• Costs $0 because you you don't have to buy or design PCB
• Fast because you don't have to design an manufacture PCB
• Collaborative because any number of developers can work in the same environment
• Developer friendly because much easier and faster to debug on PC

Requirements

This project is configured for VSCode and only tested on Linux, although this may work on OSx or WSL. It requires a working version of GCC, GDB and make in your path.

To allow debugging inside VSCode you will also require the C/C++ Tools extension Extension or other suitable debugger.

• SDL a low level driver library to use graphics, handle mouse, keyboard etc.

Usage

Get the PC project

Clone the PC project and the related sub modules:

git clone --recursive https://github.com/littlevgl/pc_simulator_sdl_eclipse.git

Install SDL

You can download SDL from https://www.libsdl.org/

On on Linux you can install it via terminal:

sudo apt-get update && sudo apt-get install -y build-essential libsdl2-dev

Setup

Configure lv_conf.h to suit your project, place your UI code in the UI folder and edit main/src/main.c to call you UI entry function. To build and debug, press F5. You should now have your UI displayed in a new window and can access all the debug features of VSCode through GDB.

To allow temporary modification between simulator and device code, a SIMULATOR=1 define is added globally.
