Using PIC18F6720 and PCWH 3.180
I have looked and cannot find any information that says I may not use a large array in my code, such as:
int MyArray[2048];
But I am experiencing problems, and if anyone knows of a problem with large arrays, please let me know.
Thanks in advance,
Birdie |

Thats a large array. You should locate the array at the beginning of a bank. The only time an array should cross a bank boundry is when it is larger than a single bank. Whenever posiable they should be located at the start of a bank.
| Code: |
int MyArray[2048];
#locate MyArray = 0x100 //Through 0x8FF
|
The process of indirect addressing will be greatly helped by not having to perform checks to see what bank is being accessed. |
