First,update some data to some widgets(label or button),then clean all widgets except scr. the last, create some widgets based on request. the issue is that after one and a half hours each times, the screen widgets data is not update and can’t control, jast like the screen is static. the code as below. pls help to confirm where the issue is?

Probably it’s because you call lv_style_init() in each timer call and it leaks memory. So probably you are out of memory 1.5 hours.

You should init the style only once and just add it to an object in the lv_timer_handler_test.

/*Copy the previous LED and set a brightness*/
lv_obj_t * led2  = lv_led_create(lv_scr_act());
lv_obj_align(led2, LV_ALIGN_CENTER, 0, 0);
lv_led_set_brightness(led2, 150);
lv_led_set_color(led2, lv_palette_main(LV_PALETTE_RED));


/*Copy the previous LED and switch it ON*/
lv_obj_t * led3  = lv_led_create(lv_scr_act());
