嵌入式linux下使用lvgl模拟器（SDL2）
这里就直接开始了，安装虚拟机和c/c++开发环境就请看正点原子的qt教程安装，同时没有CMake教程和SDL2教程，主打一个速记。
一、从官网下载lvgl源码(v8.3.9)
lvgl需要从github上面下载，网络不好请自行爬梯。
git clone -b v8.3.9 https://github.com/lvgl/lvgl.git二、下载lvgl_drivers驱动(v8.3.0)
git clone -b v8.3.0 https://github.com/lvgl/lv_drivers.git三、安装sdl2库
sudo apt-get update && sudo apt-get install -y build-essential libsdl2-dev四、必要的代码
可以从也可以从lvgl的官网找到例程，着急的兄弟也可以直接copy我改好的，这里需要他们的main.c、CMakeLists.txt、lv_conf.h和lv_drv_conf.h。
git clone --recursive https://github.com/lvgl/lv_port_linux_frame_buffer.git改好的代码
