rk_demo代码说明
主要作为一个示例程序，演示如何将官方的DEMO运行起来。以下说明略过一些无关的代码，仅挑选需要关注的代码进行说明。
static void lvgl_init(void)
{
/* 一切LVGL应用的开始 */
lv_port_init();
...
check_scr();
}
...
int main(int argc, char **argv)
{
signal(SIGINT, sigterm_handler);
struct sched_param param;
int max_priority;
max_priority = sched_get_priority_max(SCHED_fifo);
param.sched_priority = max_priority;
if (sched_setscheduler(0, SCHED_FIFO, ¶m) == -1)
{
perror("sched_setscheduler failed");
}
/* 根据配置选择对应的DEMO初始化，绘制对应UI */
#if ROCKIT_EN
RK_MPI_SYS_Init();
#endif
#if WIFIBT_EN
run_wifibt_server();
#endif
lvgl_init();
app_init();
rk_demo_init();
while (!quit)
{
/* 调用LVGL任务处理函数，LVGL所有的事件、绘制、送显等都在该接口内完成 */
lv_task_handler();
usleep(100);
}
#if ROCKIT_EN
RK_MPI_SYS_Exit();
#endif
return 0;

DEMO编译说明
触觉智能RK3506资料网盘中有提供的lvgl的demo，以下是编译方法以及demo运行方法。
解压
$ mkdir demo$ unzip lvgl_demo.zip -d demo/$ cd demo/lvgl_demo
