Grafik LCD yardım

[gocebe]

selam arkadaşlar

elimdeki sed 1335 controller li 320x240 dot grafik lcd mi pic16f877 ile programlamak istiyorum.

bana örnek olabilecek projelere ihtiyacım var çünkü pdf ler içinde kaybolmuş durumdayım.

yardımlarınız için şimdiden teşekkürler

Bu kodu renesas için yazmıştım. birkaç değişiklikle pic için de kullanabilirsin.

Kolay gelsin....

[gocebe]

çok teşekkür ederim dostum.

bi sorum daha olacak. elimde iki adet t6963c controllerli lcd ekran var. acaba240x64 ekran için yazılmış bi program 240x128 lik bi ekranda görüntü verir mi?

[Klein]

Soruyu tam anlayamadım. Ama tahminlerim üzerine bi açıklama yapayım.

sorun iki adet 240x64 ekranı 240x128 tek bir ekran gibi kullanmak ise : iki ekranı da aynı hatta bağlayıp CS uclarını kullanarak bunu yapabilirsin.  Eğer soru bu değil de 240x64 için yazılmış bir kodu 240x128 LCD'de  kullanabilirmiyim ise : Kodda çok küçük birkaç oynama  (adress , page vs.. ayarlar) yaparak kullanabilirsin.
