Arkadaşlar merhaba , aşağıda 128x64 glcd driver bulunmaktadır. Driver çalışmaktadır lakin benim yapmak istediğim data uçlarını değiştirmek ; örnekte data uçları aşağıdadır.

LCD  MCU
D0    P0.0
D1    P0.1
D2    P0.2
D3    P0.3
D4    P0.4
D5    P0.5
D6    P0.6
D7    P0.7


fakat benim istediğim aşağıdaki şekilde yapmak istiyorum (port numaraları salladım)

LCD  MCU
D0    P0.0
D1    P0.1
D2    P1.5
D3    P1.6
D4    P2.2
D5    P2.3
D6    P3.1
D7    P3.2



data yı nasıl bu şekilde parçalayabilirim işin mantığını öğrenmeye çalışıyorum o yüzden yardımcı olacak arkadaşlar direkt kodu yazmadan başka örneklerlede anlatabilirler. Şimdiden teşekkür ederim.

iyi gunler
konuyu fazla bilmiyorum sadece yardimci olmak icin yazdim program in ikinci satirinda   include "KS0108.h" yaziyor
port ayarlari diger fonksiyonlar o dosyanin icinde olmasi lazim dosyayi acip degistirebilirsiniz
anlayamazsaniz  "KS0108.h"   dosya icerigini foruma tekrar ekleyin bir inceleyim  KS0108.h dosyasi program klasorunuzun icinde veya
derleyicinin kuruldugu klasorun icinde olur arattirip bulun
