# Visual Studio simulator project for LVGL embedded GUI Library
|
||||
|
||||
|
||||
|
||||
## Introduction
|
||||
|
||||
This is a pre-configured Visual Studio project to try LVGL on a Windows PC. The
|
||||
project only depend on Win32 API, C Runtime and C++ STL, so you can compile it
|
||||
without any extra dependencies.
|
||||
|
||||
The project is currently maintained using Visual Studio 2019. It may well work
|
||||
without modification in Visual Studio 2017 but it is not actively supported
|
||||
with that version, so please install and test with Visual Studio 2019 before
|
||||
reporting any bugs.
|
||||
|
||||
Some one will notice that this repository had been renamed from
|
||||
`lv_sim_visual_studio_sdl` to `lv_sim_visual_studio`. You can read
|
||||
[here](https://github.com/lvgl/lvgl/issues/2043) and know why.
|
||||
|
||||
**This project is not for Visual Studio Code, it is for Visual Studio 2019.**
|
||||
|
||||
Instructions for cloning, building and running the application are found below.
|
||||
|
||||
## Known Issues
|
||||
|
||||
- The LV_MEM_SIZE macro in lv_conf.h should be 128KiB or larger because you may
|
||||
meet the out of memory issue when you are using the 64-bit simulator.
|
||||
- Note: In this project, the size is set to 1024KiB.
|
||||
- Users need to check the target selected in Visual Studio, because the
|
||||
simulator project support ARM64 and Visual Studio will choose ARM64 in the
|
||||
first time because of the alphabetical order.
|
||||
|
||||
## Supported Features
|
||||
|
||||
This repo is designed for keeping the simulator behavior. If you wonder to
|
||||
adapt your LVGL application to Windows, please visit
|
||||
[lvgl/lv_port_windows](https://github.com/lvgl/lv_port_windows).
|
||||
|
||||
- [x] Only depends on Win32 API, C Runtime and C++ STL.
|
||||
- [x] Native support for x86, x64 and ARM64 Windows.
|
||||
- [x] Support compiling with [VC-LTL](https://github.com/Chuyu-Team/VC-LTL)
|
||||
toolchain to make the binary size as smaller as using MinGW.
|
||||
- [x] Support Per-monitor DPI Aware.
|
||||
- [x] Support Windows keyboard and mouse wheel event in the HAL level.
|
||||
- [x] FreeType integration.
|
||||
|
||||
## Drop the ARM32 Windows support
|
||||
|
||||
For my deliberate consideration, The lv_port_windows project will drop the ARM32
|
||||
support on the Windows platform. Here are the reasons:
|
||||
|
||||
- The latest version of ARM32 version for Windows desktop is Redstone 2 Insider
|
||||
Build 15035. I know Windows RT 8.1 and Windows 10 IoT Core aren't in the
|
||||
stage of end of support, but most of daily users are drop their devices
|
||||
(Windows RT 8.x tablets) or have a better solution (Windows 10 IoT Core users
|
||||
on Raspberry Pi devices should migrate to Linux or ARM64 version for Windows
|
||||
10 desktop).
|
||||
- Future ARM processors are deprecating ARM32 ISA support, and Apple Silicon M1
|
||||
had dropped the ARM32 support at all. So we can't run ARM32 version of Windows
|
||||
desktop applications on these devices.
|
||||
- Reduce the size of release package and make the continuous integration faster.
|
||||
|
||||
## How to Clone
|
||||
|
||||
This repository contains other, necessary LVGL software repositories as
|
||||
[git submodules](https://git-scm.com/book/en/v2/Git-Tools-Submodules). Those
|
||||
submodules are not pulled in with the normal git clone command and they will be
|
||||
needed. There are a couple of techniques to pull in the submodules.
|
||||
|
||||
### Everything at Once
|
||||
|
||||
This command will clone the lv_sim_visual_studio repository and all submodules
|
||||
in a single step.
|
||||
|
||||
```
|
||||
git clone --recurse-submodules https://github.com/lvgl/lv_sim_visual_studio.git
|
||||
```
|
||||
|
||||
### Main Repository First, Submodules Second
|
||||
|
||||
If you've already cloned the main repository you can pull in the submodules
|
||||
with a second command. Both commands are shown below.
|
||||
|
||||
```
|
||||
git clone https://github.com/lvgl/lv_sim_visual_studio.git
|
||||
cd lv_sim_visual_studio
|
||||
git submodule update --init --recursive
|
||||
```
|
||||
|
||||
### Keeping Your Clone Up-To-Date
|
||||
|
||||
If you have cloned this repository and would like to pull in the latest
|
||||
changes, you will have to do this in two steps. The first step will pull in
|
||||
updates to the main repo, including updated _references_ to the submodules. The
|
||||
second step will update the code in the submodules to match those references.
|
||||
The two commands needed to accomplish this are shown below, run these commands
|
||||
from inside the main repository's directory (top level `lv_sim_visual_studio`
|
||||
directory works fine).
|
||||
|
||||
```
|
||||
git pull
|
||||
git submodule update --init --recursive
|
||||
```
|
||||
|
||||
If you have chosen to fork this repository then updating the fork from upstream
|
||||
will require a different, more involved procedure.
|
||||
|
||||
## How To Build & Run
|
||||
|
||||
Open the `LVGL.Simulator.sln` solution file in Visual Studio. Set the
|
||||
`LVGL.Simulator` project as the startup project. Click on the `Local Windows
|
||||
Debugger` button in the top toolbar. The included project will be built and
|
||||
run, launching from a cmd window.
|
||||
|
||||
## Trying Things Out
|
||||
|
||||
There are a list of possible test applications in the
|
||||
[LVGL.Simulator.cpp](LVGL.Simulator/LVGL.Simulator.cpp) file. Each test or demo
|
||||
is launched via a single function call. By default the `lv_demo_widgets`
|
||||
function is the one that runs, but you can comment that one out and choose any
|
||||
of the others to compile and run.
|
||||
|
||||
Use these examples to start building your own application test code inside the
|
||||
simulator.
|
||||
|
||||
## A Note About Versions
|
||||
|
||||
This repository has its submodule references updated shortly afk with minor
|
||||
version updates. When submodule updates take place a matching version tag is
|
||||
added tter the release of new, major releases of LittlevGL's core
|
||||
[lvgl](https://github.com/lvgl/lvgl) project. Occasionally it is updated to
|
||||
woro this repository.
|
||||
|
||||
If you need to pull in bug fixes in more recent changes to the submodules you
|
||||
will have to update the references on your own. If source files are added or
|
||||
removed in the submodules then the visual studio project will likely need
|
||||
adjusting. See the commit log for examples of submodule updates and associated
|
||||
visual studio file changes to guide you.
