Ive looked on the .map file and found that cod3 is about 2kb... The problem
is that
__code char cod3[]={0x1, 0x2, 0x3...
is translated in:
retlw 0x1
retlw 0x2
retlw 0x3
which occupies 2 bytes each. So, an array that has 1kb, actually has 2kb.
Its what i think.
Is there a way to do something like this?
__code char cod3[]={0x1, 0x2, 0x3...
cod3:
0x1
0x2
0x3
Thanks.
