What do you want to achieve?
I want to use the label which is present in the component, in user function.
What have you tried so far?
I want to set the date so i created label and i tried to add user function and call it in timer. i am getting segmentation fault when i run the build.

Hi, I had tried like this it’s not showing any error but its not enter the if condition only to get the date and time.
//Update Date and Time label -> ui_Label5 in footer from the structure
if(lv_obj_get_screen(ui_comp_get_child(ui_footerPanel, UI_COMP_FOOTERPANEL_LABEL5) ) == lv_scr_act())
sprintf(buf, "%02d %s %04d %02d:%02d %s", tDateTime.day, GetMonthName(tDateTime.month), tDateTime.year, tDateTime.hour,tDateTime.minute, GetAMPM(tDateTime.hour));
lv_label_set_text(ui_comp_get_child(ui_footerPanel, UI_COMP_FOOTERPANEL_LABEL5), buf);
Why you mean this will work? You need ask obj on screen no component def name.
Thank you Marian… I didn’t get how to use, could you please help me out of this?
My crystal ball say your object on screen have other name … and better is check existent component on screen as his child…
Ok Marian I will check. Thank you so much.
Please print these:
lv_obj_t * comp = ui_comp_get_child(ui_footerPanel, UI_COMP_FOOTERPANEL_LABEL5);
lv_obj_t * comp_screen = lv_obj_get_screen(comp_screen);
lv_obj_t * act_scr = lv_scr_act();
printf("%p, %p, %p\n", comp, comp_screen, act_scr);
