LittleV GUI相关总结
The whole graphics library project consists of a few repostories:
- lvgl the graphics library itself
- lv_examples tutorials and example GUI applications
- lv_boards ready to use project on various development boards and microcontrollers
- lv_drivers drivers for common touch pad and display controllers
- lv_utils image and font converter utilities
- pc_simulator a cross platform simulator project to run LittlevGL on PC
一、PC端模拟器开发环境搭建
软件下载地址：
1.Eclipse CDT
eclipse-cpp-oxygen-R-win32-x86_64.zip
2.SDL2
SDL2-devel-2.0.7-mingw.tar.gz
3.MinGW-w64
x86_64-7.2.0-release-win32-sjlj-rt_v5-rev0.7z
1、Install Eclipse CDT
Eclipse CDT is C/C++ IDE. You can use other IDEs as well but in this tutorial the configuration for Eclipse CDT is shown.
Eclipse is a Java based software therefore be sure Jave Runtime Environment is installed on your system.
On linux: sudo apt-get install default-jre
You can download Eclipse's CDT from: https://eclipse.org/cdt/. Start the nstaller and choose *Eclipse CDT* from the list
2、Install MinGW
官方MinGW很难下载，选择MinGW-w64替代。解压到某个目录，并且添加环境变量D:\mingw64\bin，打开CMD，输入gcc -v测试是否添加成功。重命名mingw64\bin下的mingw32-make.exe为make.exe
3、Install SDL 2
1）Download the development libraries of SDL.
Go to https://www.libsdl.org/download-2.0.php and download Development Libraries: SDL2-devel-2.0.5-mingw.tar.gz
2）Uncompress the file and go to x86_64-w64-mingw32 directory (for 64 bit MinGW) or to i686-w64-mingw32 (for 32 bit MinGW)
3）Copy x86_64-w64-mingw32/include/SDL2 folder to D:\mingw64\x86_64-w64-mingw32/include
4）Copy x86_64-w64-mingw32/lib/ content to D:\mingw64\x86_64-w64-mingw32\lib
5）Copy x86_64-w64-mingw32/bin/SDL2.dll to {eclipse_worksapce}/pc_simulator/Debug/. Do it later when Eclipse is installed.
4、Import pre-configed project to Eclipse
File->Import and choose General->Existing project into Workspace.
注：这里导入后，需要对工程的properties做一些修改，否则会出现
undefined reference to `[email protected]'错误
5、Compile and Run
编译前需要修改main.c里的int main(void)为int main(int argc, char *argv[])，否则报声明和定义不符的错误
