thanks!

You need to add a 'REQUIRES driver' to the idf_component_register of your component.

suggest set bigger lv memory size to have a try:

(Top) → Component config → LVGL configuration → Memory settings
Espressif IoT Development Framework Configuration
[ ] If true use custom malloc/free, otherwise use the built-in `lv_mem_alloc()` and `lv_mem_free()`
(64) Size of the memory used by ...

I (288) sleep: Configure to isolate all GPIO pins in sleep state
I (295) sleep: Enable automatic switching of GPIO sleep configuration
I (302) app_start: Starting scheduler on CPU0
I (307) app_start: Starting scheduler on CPU1
I (307) main_task: Started on ...

Note that this function can not raise log level above the level set using CONFIG_LOG_MAXIMUM_LEVEL setting in menuconfig.

idf.py 打印日志中汉字的总是带上菱形问号，如下所示:
