Memory Overflow

[Marcelocm1995]

Description

Hello All!

I’m getting a memory overflow on lvgl memory.
My code creates an led, then delete this led. This routine repeats a few times, but my memory usage increases until generate overflow, crashing my ui.

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

STM32F4

What LVGL version are you using?

7.10.1

What do you want to achieve?

Control my memory usage

What have you tried so far?

Use LV_MEM_AUTO_DEFRAG

Code to reproduce

#  define LV_MEM_AUTO_DEFRAG  1
#  define LV_MEM_SIZE    (16U * 1024U)

void refresh_RPM_linemeter(lv_task_t *t)
{
    lv_linemeter_set_value(t->user_data, Map(ENGINE_RPM, 0, 7000, 0, 100));
    if ((ENGINE_RPM >= ShiftLightThrs) && (flag_shift_light == 0))
    {
        create_shift_light();
        flag_shift_light = 1;
        lv_led_on(screen_shift_light);
    }
    if ((ENGINE_RPM < ShiftLightThrs) && (flag_shift_light == 1))
    {
        flag_shift_light = 0;
        lv_obj_clean(screen_shift_light);
        lv_obj_del(screen_shift_light);
    }
}
