pointerlar hakkında

[gokhangokcen]

Merhabalar,
bir menü algoritması tasarlamak için uğraşıyorum.Devrede 4'lü ortak katod display ve rotary encoder'im var şu butonlu olanlardan. Bu menü işini daha önce @Klein hocamızın değindiği gibi pointerlar ile yapmaya çalışıyorum.
Fakat pointerlara fazla hakim olmadığım için tıkandım.Bilen arkadaşlar yardımcı olursa sevinirim. Kodlarım şu şekilde;

şimdi sormak istediğim mevzular şu şekilde;

1- Pointer (Item) menu fonksiyonunun içerisinde oluşuyor ve fonksiyondan çıktığında içeriği hep 0 olarak başlıyor. Dolayısı ile

if(menüartibuton){
  Item++;
}

dediğimde o anlık arttırıyor örneğin test iteminden p001 itemine geçiyor ama fonksiyondan çıktığı an tekrar test itemine geri dönüyor. kendimde bir şeyler denedim. büyük bir ihtimalle hatalı. menuNo adında değişken oluşturup onunla toplayarak değer yüklemeye çalıştım. iş görüyor gibi..

2- Item pointerındaki değişkenlere nasıl erişebilirim? kalıcı bir değişkene nasıl atayabilirim?
3- Bu değerleri arttırıp azalttıktan sonra tekrar pointer üzerine nasıl yüklerim?

Not: main.h ve diğer eklentileri yüklemedim. klasik pin tanımlamaları vs var. isterseniz yükleyebilirim

yanıt veren arkadaşlara şimdiden teşekkürler.

Pointerlar gerçekten bu kadar zor bir konu mu? Hiç kimse bir yorumda bile bulunmamış. Ya da ben mi soru sormayı beceremedim acaba?

Onlarca cozum vardir ama en hizlisi Item degiskenini global olarak tanimla.

[gokhangokcen]

@brandice5 üstad Item pointeri menu fonksiyonu içerisinde tanımlanmış. bunu maine aldığım zaman bu sefer menu fonksiyonu bu şekilde bir değişken yok diye uyarı veriyor.

[brandice5]

main icine degil, aynen uint8_t menuNo = 0; yaptigin gibi global oalrak tanimla.

o satirin altina;

TMenuItem *Item;

ekle.

[gokhangokcen]

typedef struct{
   char *Header;
   int *Var;
   int min;
   int max;
}TMenuItem;

int a = 123;
int b = 456;
int c = 789;
int d = 99;
int e = 111;

TMenuItem menuValue[] = {
     {"TEST", &a, 0, 0},
     {"P001", &b, 45, 70},
	 {"P002", &c, 80, 90},
	 {"P003", &d, 10, 100},
	 {"P004", &e, 7, 99},
     {"SON"},
};

uint8_t *Item;
TmenuItem = *Item;

şeklinde bahsediyorsunuz sanırım. denedim ama şöyle bir hata verdi;
