2.2 移植 LVGL

cd tspi_lvgl
git clone -b v8.3.0 https://github.com/lvgl/lvgl.git
git clone -b v8.3.0 https://github.com/lvgl/lv_drivers.git


*****************************************lvgl修改***************************************************
# 将lvgl的配置文件lv_conf_template.h移动到tspi_lvgl目录，并重命名为lv_conf.h
# 1、将第15行附近： if 0 改为 if 1
# 2、使能第49行附近：#define LV_MEM_CUSTOM 1
# 3、使能一个示例demo：#define LV_USE_DEMO_BENCHMARK 1
# 4、使能该demo需要的字体：#define LV_FONT_MONTSERRAT_24 1


******************************************lv_drivers修改********************************************
# 将lv_drivers的配置文件lv_drv_conf_template.h移动到tspi_lvgl目录，并重命名为lv_drv_conf.h
# 1、将第11行附近： if 0 改为 if 1
# 2、使能第177行附近：#define USE_WAYLAND       1
# 3、在该行后面添加一行：#define LV_WAYLAND_TIMER_HANDLER 1
# 4、修改184行附近的几行：
		#    define LV_WAYLAND_CLIENT_SIDE_DECORATIONS 0
		#    define LV_WAYLAND_WL_SHELL 0
		#    define LV_WAYLAND_XDG_SHELL 1
# 5、进入lv_drivers/wayland目录,在该目录下打开一个终端黑窗口，执行下面程序
export CC=/usr/bin/aarch64-linux-gnu-gcc     #指定自己的交叉编译工具链
cmake .		  # 生成Makefile文件
make -j32	  # 编译，j后面的数字根据自己的线程数指定，也可以直接用make，速度会慢些

2.2.2 编写自己的UI界面

1、在tspi_lvgl目录下新建components目录
2、在components目录下新建CMakeList.txt文件
3、使用SquareLine_Studio生成界面，新建ui_code文件夹，将导出的代码放置在该目录下
4、拷贝ui_code到目录components目录下
5、修改tspi_lvgl目录下的CMakeList.txt文件
6、在main.c中添加头文件，和运行自己的ui即可
