Increase heap memory

How-to
1

Hello,

Function below show me I have used to much memory for one form:

used: 26832 ( 41 %), frag: 3 %, biggest free: 37580

I afraid I need more memory for other ones. I must keep all forms in memory at the same time.

How to increase heap memory? What does counter 26832 means? Is it in bytes?

static void memory_monitor(lv_task_t * param)
{
    (void) param; /*Unused*/

    lv_mem_monitor_t mon;
    lv_mem_monitor(&mon);
    printf("used: %6d (%3d %%), frag: %3d %%, biggest free: %6d\n", (int)mon.total_size - mon.free_size,
            mon.used_pct,
            mon.frag_pct,
            (int)mon.free_biggest_size);

}
