lv_calendar_set_day_names(tos_calendarObj, cal_days);

but i dont take screen and simulator closing itself;

My calender all function;
void tos_calendarCalendar(void) {
const char *cal_days[7] = { “Pzt”, “Sal”, “Car”,“Per”,“Cum”,“Cmt”,“Paz” };
tos_calendarObj = lv_calendar_create(lv_scr_act(), NULL);

	lv_obj_set_size(tos_calendarObj, 200, 200);
	lv_obj_align(tos_calendarObj, NULL, LV_ALIGN_CENTER, 0, 0);
	lv_calendar_set_day_names(tos_calendarObj, cal_days);
	lv_obj_set_event_cb(tos_calendarObj, tos_calendar_CalendarEvent);

	today.year = tos_calendarYears;
	today.month = tos_calendarMonths;
	today.day = tos_calendarDays;
	lv_calendar_set_today_date(tos_calendarObj, &today);
	lv_calendar_set_showed_date(tos_calendarObj, &today);

	static lv_calendar_date_t highlihted_days[1];       /*Only it's pointer will be saved so should be static*/
	highlihted_days[0].year = 2020;
	highlihted_days[0].month = 5;
	highlihted_days[0].day = 12;
	lv_calendar_set_highlighted_dates(tos_calendarObj, highlihted_days, 1);


These are not normal " s. You should pass an array with constant string like this:

    const char *cal_days[7] = { "Pzt", "Sal", "Car","Per","Cum","Cmt","Paz" };

Or is just a copy-paste/auto formatting issue at some point, and you have normal "s in your project?
