lcd pinleri değiştirmek

[armsistem]

Arkadaşlar merhaba aşağıda lcd port pinleri P0.4-P0.5-P0.6-P0.7 ne yaparsam yapayım portları kaydıramadım gözden kaçırdığım nokta neresi.

#define  LCD_D4  0x10   //P0.04
#define  LCD_D5  0x20   //P0.05
#define  LCD_D6  0x40   //P0.06
#define  LCD_D7  0x80   //P0.07

Örnek : LCD_D4 = 0x10 (hex)----> 00010000  ---- LPC2104 'nın P0.4

Yukarıdaki 2 satırıda uygun şekilde değiştirdiniz mi? Birde bu dosyalar bu haliyle çalışıyor değil mi?

#define  LCD_D4  0x10   //P0.04 #define  LCD_D5  0x20   //P0.05 #define  LCD_D6  0x40   //P0.06 #define  LCD_D7  0x80   //P0.07

bu satırları mı değiştirdiniz sadece.

[armsistem]

Evet iki satırıda değiştirdim.
