picc18 large array code picc18

Hello, bes

Maybe your problem comes from BANKs problems or limit amount of RAM.
1st possible solution is :
Using the instruction of const, declare your array on ROM area.

2nd possible solution is :
Please check how much RAM is needed in your source code.
If you using 8-bits char integer two of 12X24 array is need 576 bytes RAM.
Other case 16-bits int integer is need 1152 bytes and
24-bits floats are need 1728 bytes-it's out of bounce and
32-bits floats or long or doubles are 2304 byte- it also out of range.

I hope aboves can help you.

Good luck.
