Veškeré grafické objekty jsou uložené na SD kartě, z toho důvodu trvá déle načtení.
Toto je pouze zkušební demo, pro zjištění rychlosti komunikace MCU s displejem.
Po tomto testu jsem došel k názoru že není ideální zobrazovat obrázky s 24bitovou barevnou hloubkou.
Protože načítaní trvá příliš dlouho.
