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。

在Linux平台搭建LVGL模拟器

1. 安装SDL2

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

2. 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

3. 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

4. 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

5. 编写Makefile

   	@echo 'Building project file: $<'
   	@mkdir -p $(dir $@)
   	@$(COMPILE) -c -o "$@" "$<"
   
   default: $(OBJECTS)
   	@mkdir -p $(BIN_DIR)
   	$(CC) -o $(BIN) $(OBJECTS) $(LDFLAGS) ${LDLIBS}
   
   clean:
   	rm -rf $(WORKING_DIR)
   
   install: ${BIN}
   	install -d ${DESTDIR}/usr/lib/${PROJECT}/bin
   	install $< ${DESTDIR}/usr/lib/${PROJECT}/bin/
   

6. 修改main.c头文件，去除模拟器鼠标指针
