asm error: not enough RAM

Recommended Posts

I'm working on a LCD panel and need to code the fonte table. I'm doing something like this:


char TabelaChr(char letter, char position){

char FontLookup[] ={

0x00, 0x00, 0x2f, 0x00, 0x00,   // !

0x24, 0x2a, 0x7f, 0x2a, 0x12,   // $

0xc4, 0xc8, 0x10, 0x26, 0x46,   // %

0x00, 0x60, 0x60, 0x00, 0x00,   // .

(and so on)


When compiling, SouceBoost 5.3 & 5.4 says: Not enough RAM.

If I delete parts of the table, it goes OK.


The point is that my code is quite small and the whole table has 225 chars and everything fits inside a 16F628 leaving a lot of room.


I would like to know how to fix this behaviour.

This is not a bug. A variable must fit into a register bank and array 'FontLookup' that you use in the code is too big for this.

Sorry for this. Just after I posted, I found out what was wrong:


This should be a CONST char[] and not a char[].

The compiler was trying to allocate register RAM for my table data.

OOps ;)


Anyway, thanks for the quick reply!
