OLED Problemim (SSD1305)

[Eren Eraslan]

Merhabalar

Winstar'ın WEX012864ELPP3N markalı OLED ekranını sürmeye çalışıyorum. Hazır kütüphane buldum + Driver Devresi çıkardım...Fakat belli başlı problemlerim oldu. Öncelikle ekrandan hiçbir şekilde tepki alamıyorum. Tamamen karanlık. Init edemiyorum belli ama Power On prosedürünü bile yapsam (AFh) değişim yok. Kodları PCB tasarımını ve Datasheetleri linkte paylaştım. Yardımcı olanlara teşekkür ederim şimdiden.

Koda baktımda paralelden gönderiyorsun sanırım.SPI kullanamaz mısın ?

Birde initte çok fazla bekleme var. Datasheet mi böyle yazıyor ?

evet paralelden gönderiyorum elimdeki pcb ona göre var hocam. Ya winstar'ın bana verdiği örnek kodu da paylaşayım. O init rutini de çalışmadı.
