2.2.1 新建 tspi_lvgl 工程
克隆lvgl库和lvgl_drivers库，这两个库均选择8.3版本，按照如下说明进行修改
mkdir tspi_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，速度会慢些新建CMakeLists.txt文件，内容如下。
cmake_minimum_required(VERSION 3.1)
project(tspi_lvgl)
SET(CMAKE_SYSTEM_NAME Linux)
SET(CMAKE_C_COMPILER /usr/bin/aarch64-linux-gnu-gcc) # 指定编译器
SET(GCC_WAYLAND_LINK_FLAGS "-lwayland-client -lwayland-cursor -lxkbcommon -lpthread -lffi") # 链接
include_directories(.)
add_subdirectory(lvgl)
add_subdirectory(lv_drivers)
add_executable(${PROJECT_NAME} main.c )
target_link_libraries(${PROJECT_NAME} PRIVATE lvgl lvgl::examples lvgl::demos lvgl::drivers)
target_link_libraries(${PROJECT_NAME} PRIVATE ${GCC_WAYLAND_LINK_FLAGS})将动态连接库复制到交叉编译工具链的lib目录下
# 所需要的动态连接库,位置：<SDK>/buildroot/output/rockchip_rk3566/target/usr/lib64
libxkbcommon.so

libwayland-client.so.0.20.0
libwayland-cursor.so
libwayland-cursor.so.0
libwayland-cursor.so.0.20.0
libffi.so
libffi.so.6
libffi.so.6.0.4
# 拷贝到ubuntu交叉编译工具链下面，我的交叉编译工具链库位置：/usr/aarch64-linux-gnu/lib
sudo cp libxkbcommon.so libxkbcommon.so.0 ... libffi.so.6.0.4 /usr/aarch64-linux-gnu/lib
# 将动态库拷贝到泰山派上面的 usr/lib 目录下面，泰山派上面有的就不用拷贝了
1、连接wifi
2、buildroot中开启openssh
3、用scp命令发送文件，或者用软件连接都可以在tspi_lvgl目录下新建main.c文件，内容如下：
#include "lvgl/lvgl.h"

#include "lvgl/demos/lv_demos.h"
#include <limits.h>

{

lv_wayland_window_set_fullscreen(disp,true);
lv_demo_benchmark();
// lv_demo_widgets();
struct pollfd pfd;
uint32_t time_till_next;
int sleep;
pfd.fd = lv_wayland_get_fd();
pfd.events = POLLIN;
while (1)
{
/* Handle any Wayland/LVGL timers/events */
time_till_next = lv_wayland_timer_handler();
/* Run until the last window closes */
if (!lv_wayland_window_is_open(NULL))
{
break;
}
/* Wait for something interesting to happen */
if (time_till_next == LV_NO_TIMER_READY)
{
sleep = -1;
}
else if (time_till_next > INT_MAX)
{
sleep = INT_MAX;
}
else
{
sleep = time_till_next;
}
lv_tick_inc(50);
lv_timer_handler() ;
while ((poll(&pfd, 1, sleep) < 0) && (errno == EINTR));
}
return 0;
}建好的tspi_lvgl工程结构如下

./tspi_lvgl 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

# 修改main.c文件

修改lvgl配置文件lv_conf.h即可，修改内容如下
#define LV_USE_FS_STDIO 1
#if LV_USE_FS_STDIO
#define LV_FS_STDIO_LETTER 'S' /*Set an upper cased letter on which the drive will accessible (e.g. 'A')*/
#define LV_FS_STDIO_PATH "" /*Set the working directory. File/directory paths will be appended to it.*/
#define LV_FS_STDIO_CACHE_SIZE 1024 /*>0 to cache this number of bytes in lv_fs_read()*/
#endif在main.c文件中使用下面函数测试，看能否读取到目录信息。
void FileTest(void)
{
lv_fs_dir_t dir;
lv_fs_res_t res;
res = lv_fs_dir_open(&dir, "S:/");
char fn[256];
while(1) {
res = lv_fs_dir_read(&dir, fn);
if(strlen(fn) == 0) {
break;
}
printf("%s\n", fn);
}
lv_fs_dir_close(&dir);
}

2.2.4 移植 lottie 动画
1、下载rlottie仓库
git clone https://github.com/Samsung/rlottie.git2、编译rlottie
# 进入rlottie根目录
cd rlottie
mkdir build
cd build
# 指定编译器
export CC=/usr/bin/aarch64-linux-gnu-gcc # 根据自己的编译器位置修改
export CXX=/usr/bin/aarch64-linux-gnu-g++ # 根据自己的编译器位置修改
# 编译项目
cmake ..
make -j32
# 将生成的动态库拷贝到ubuntu交叉编译工具链下
sudo cp librlottie.so librlottie.so.0 librlottie.so.0.2 /usr/aarch64-linux-gnu/lib/
# 将生成的动态度拷贝到泰山派/usr/lib目录下
scp librlottie.so librlottie.so.0 librlottie.so.0.2 root@192.168.1.69:/usr/lib
3、修改tspi_lvgl目录下的CMakeList.txt文件，完整内容如下
cmake_minimum_required(VERSION 3.1)
project(tspi_lvgl)
SET(CMAKE_SYSTEM_NAME Linux)
SET(CMAKE_C_COMPILER /usr/bin/aarch64-linux-gnu-gcc)
# 添加了-rlottie 链接
SET(GCC_WAYLAND_LINK_FLAGS "-lwayland-client -lwayland-cursor -lxkbcommon -lpthread -lffi -lrlottie")
include_directories(.)
include_directories(./components/ui_code)
# 添加了头文件
include_directories(/home/wrt/Taishan/TaiShan_Ui/libraries/rlottie/rlottie/inc)
add_subdirectory(lvgl)
add_subdirectory(lv_drivers)
add_subdirectory(components)
add_executable(${PROJECT_NAME} main.c )
target_link_libraries(${PROJECT_NAME} PRIVATE lvgl lvgl::examples lvgl::demos lvgl::drivers)
target_link_libraries(${PROJECT_NAME} PRIVATE ${GCC_WAYLAND_LINK_FLAGS})
target_link_libraries(${PROJECT_NAME} PRIVATE ui)
4、修改lvgl的配置文件lv_conf.h,使能rlottie
#define LV_USE_RLOTTIE 15、修改main.c程序，测试lottie动画，在如下目录中放入一个lottie动画文件。
// 注意这里的文件路径不要带S标志，因为使用的是rlottie自己的文件系统
lv_obj_t *lottie = lv_rlottie_create_from_file(ui_Panel1, 300, 300, "/root/astronut.json");
lv_obj_center(lottie);6、运行程序时出现错误，stdc++库版本出现下面问题。
# 进入ubuntu的/usr/aarch64-linux-gnu/lib目录下
strings libstdc++.so.6 | grep GLIBCXX #执行该命令，发现有上述所需的版本
GLIBCXX_3.4.29
GLIBCXX_3.4.30
# 进入泰山派的/usr/lib目录下
strings libstdc++.so.6 | grep GLIBCXX #执行该命令，发现没有上述所需的版本
GLIBCXX_3.4.27
GLIBCXX_3.4.28
# 拷贝过去
scp libstdc++.so.6 root@192.168.1.69:/usr/lib
# 重启一下开发板
reboot
# 执行程序
cd root
./tspi_lvgl
# 下面的动画是会动的
