değişken boyutu sorunu

[f628]

iyi akşamlar arkadaşlar, 18f452de çalıştırdığım devreyi 16f877de çalıştırmak istiyorum lakin değişken fazla büyük diye hata verdiği için derleyemiyorum, acaba nasıl halledebilirim bu sorunu???

değişken;

const int8 image_2[64][16] = {

Evternal hafızaya yönelinebilir.Eeprom gibi...

[f628]

o nasıl yapılıyor hocam biraz açabilir misin acaba???

[Tagli]

EEPROM'a da RAM'e de sığmaz, mümkün değil. Program hafızasına gömülebileceğini sanıyorum.

[AsHeS]

EEPROM'a da RAM'e de sığmaz, mümkün değil. Program hafızasına gömülebileceğini sanıyorum.

const tanımladığı için direkt program hafızasına gömülüyor mu zaten ?

[Tagli]

Derleyicisine göre değişir. C18 ve XC8'de o şekilde oluyor. CCS C'yi bilmiyorum.

[f628]

Evternal hafıza yada yazılıma gömmeyi araştırmama karşın düzgün bir bilgi bulamadım :/ protonda ki gibi değişkeni başka bir yere kaydedip yazılımın içinde çağırmak mı kast ediliyor programa gömmek derken?

[AsHeS]

Derleyicisine göre değişir. C18 ve XC8'de o şekilde oluyor. CCS C'yi bilmiyorum.

XC8 ve Hi-Tech de öyle olduğuna göre CCS ye göre de öyledir herhalde diye düşündüm.

[Tagli]

Burada yazdığına göre CCS C'de de mantık aynıymış.

Derleyicinin verdiği hata tam olarak nedir?
Diziyi tek boyutlu olarak tanımladığında da hata veriyor mu?
Diziyi küçülterek tanımladığında - mesela yarı boyutundayken - hata veriyor mu?
Dizi tanımlı değilken, programın kendisi ne kadar yer kaplıyor?

[sadogan]

ccs  const tanımlandıgı için  program hafızasına gömüyor
tabloyu 255 byte uzunlugunu gecmeyecek şekilde düzenleyip denermisiniz

[mozkan87]

CCS C için bir şey diyemem ama hitech bu kodu derler daha önce grafik lcd ile uğraşırken aynı diziyi hem iki boyutlu olarak tanımladım hem tek boyutlu olarak tanımlayıp derledim sorun olmuyordu.

[f628]

''data item too big'' ve ''expecting a declaration'' hatası veriyor.

eğer diziyi const int8 image_2 [16][16] yaparsam derliyor.

[Tagli]

gerbay hocam, senin dediğinin aksini söylerken insan kendinden emin olamıyor ama, benim bildiğim kadarıyla int degisken[2][2] = {1,2,3,4}; gibi bir tanım C söz dizimine uygun.

[f628]

evet 18f452'de derlediğine eminim. hiç zorlanmadan derliyor.

[sadogan]

''data item too big'' ve ''expecting a declaration'' hatası veriyor.

eğer diziyi const int8 image_2 [16][16] yaparsam derliyor.

Tabloyu 16*16  veya 64*4  şeklinde 4 parcaya bölerek yapman gerekebilir.
