\n5-) 3V3<\/strong> luk sistemlerle uyumlu haberle\u015febilmesi.
\n6-) Ekrandan karakter okuma<\/strong>
\n7-) PCB nin ters tak\u0131labilmesi<\/strong> m\u00fcmk\u00fcnd\u00fcr. ( LCD Ba\u011flant\u0131 pinlerinin durumuna g\u00f6re )

\nEprom\u2019a fazladan 24 yeni karakter depolanabilir<\/strong>.
\n2<\/strong> yada 4 sat\u0131r<\/strong> olan LCD ler kullan\u0131labilir. Tek sat\u0131rlarda kullan\u0131labilir fakat bu \u00f6zellik sadece proteus modellerinde denendi<\/strong>. Aradaki fark ise datasheet’e g\u00f6re DDRAM adreslemesinden kaynaklan\u0131yor. \u015eayet paralel data olarak kullan\u0131rken, ilk sat\u0131r ve s\u00fctun adresi olarak 80h kullan\u0131yorsan\u0131z bu mod\u00fcl\u00fc kullanabilirsiniz diye d\u00fc\u015f\u00fcnebilirsiniz.
