Description

how to create defined number of an object as a child on a panel as parrent. based on lvgl library the output of lv_label_create function is (lv_obj_t *). I want to create N number of Lables after the N was Defined. but using the below code results to Hardfault.

What MCU/Processor/Board and compiler are you using?

stm32g769igt6

What LVGL version are you using?

V8.2

What do you want to achieve?

how to define a N number of an object (lable in my case) in a for loop function

What have you tried so far?

the below code

Code to reproduce

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

The code block(s) should be formatted like:

/*		    uint16_t NumberOfAlarms = 5;

		    lv_obj_t ** AlarmsLable_OBJ;

		    lv_obj_t ** AlarmsType_OBJ;


		    for(uint8_t i = 0; i < NumberOfAlarms; i++){

		    	*(AlarmsLable_OBJ + i) = lv_label_create(ui_ParamAlarmsChildPanel);

			    lv_obj_set_width(*(AlarmsLable_OBJ + i), LV_SIZE_CONTENT);   /// 1
			    lv_obj_set_height(*(AlarmsLable_OBJ + i), LV_SIZE_CONTENT);    /// 1*/
