Friendly_lv_ui: A C repository from 24849748

该仓库为本人自学LVGL所写的demo，欢迎学习交流！

该项目在Linux平台上模拟运行，使用LVGL v8.2.0版本，基于官方Linux模拟器工程修改：

删除部分example、demo和其他无关文件
修改目录结构
使用自己的demo程序

后续不同UI将以分支形式push，不再另建仓库。

以下记录自己搭建的过程：

在Linux平台搭建LVGL模拟器

安装SDL2

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

构建目录

.
├── build
│   └── bin				// 可执行文件生成目录
├── lv_apps				// 存放ui程序
├── lv_drivers			
├── lvgl
├── lv_conf.h			// lvgl库配置头文件
├── lv_drv_conf.h		// lv_drivers库配置头文件
├── main.c				// 主程序
└── Makefile

拉取lvgl库和lvgl_drivers库

git clone -b release/v8.2 https://github.com/lvgl/lvgl.git
git clone -b release/v8.2 https://github.com/lvgl/lv_drivers.git

lv_conf.h和lv_drv_conf.h
```
cp lvgl/lv_conf_template.h lv_conf.h
cp lv_drivers/lv_drv_conf_template.h lv_drv_conf.h
```
- 启用两个文件，#if 1
- lv_drv_conf.h配置需要开启USE_MONITOR、USE_MOUSE、USE_MOUSEWHEEL和USE_KEYBOARD
- 其他按需求修改

编写Makefile

修改main.c头文件，去除模拟器鼠标指针
