Simulator project for LVGL embedded GUI Library

LVGL v8.3 模拟器，基于以下仓库：

• https://github.com/lvgl/lv_port_pc_vscode/tree/release/v8
• https://github.com/lvgl/lvgl/tree/release/v8.3
• https://github.com/lvgl/lv_drivers/tree/release/v8.3

运行方法：

• VS Code WSLg 环境里：mkdir build; cd build; cmake ..; make; ./demo
• Windows 环境里 VS2019（或以上版本）文件菜单打开 CMake 文件，点击运行 demo.exe

--- 以下是原版 README ---

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 don't have to buy or design PCB
• Fast because you don't have to design and 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 a GDB extension or other suitable debugger. All the requirements have been pre-configured in the .workspace file (simply open the project by doubleclick on this file).

The project can use SDL or X11 as LVGL display driver for lowlevel graphics/mouse/keyboard support. This can be defined in the Makefile. Please make sure the selected library is installed in the system (check Install graphics driver).

Usage

Get the PC project

Clone the PC project and the related sub modules:

git clone --recursive https://github.com/lvgl/lv_port_pc_vscode

Install graphics driver

The project can use SDL or X11 as LVGL display driver. This can be selected in the Makefile. Please make sure the used library is installed in the system:

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

Install X11

On on Linux you can install it via terminal:

sudo apt-get update && sudo apt-get install -y libx11-dev

Setup

To allow custom UI code an lv_conf.h file placed at ui/simulator/inc will automatically override this projects lv_conf.h file. By default code under ui is ignored so you can reuse this repository for multiple projects. You will need to place a call from main.c to your UI's 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.
