Fuses in HEX file
PostPosted: Mon Aug 15, 2005 8:37 am     Reply with quote

Hello,
I would like to include configuration bit to Hex file.
Normany If I use ccs, I do it with derective #fuses.
If I use MPLAB I cant use #fuses, I get error from compiler: Unknown keyword in #FUSES
How can I include configuration bit in HEX file using MPLAB?
Thanks
Mark

Are you still using CCS's compiler??? If not, then what are you using. MPLAB is just an IDE so you'll have to tell us what language toolsuite that you are using.

Ah. I found.
Configuration bit for PIC12F629 could be programmed like:
#ROM 0x2007 = {0x3FE4}
Where 0x2007 is configuration bit address
0x3FE4 is conf bit itself.

But.... It is still interesting.
I use MPlab 6.4. Compiler for the project is "CCS Compiler for 12/14/16/18"
It is still strange. If I use CCS IDE, I can use #fuse. If I use MPlab IDE
I get this strange error......

Sounds like you don't have the correct device selected in MPLAB or you are using to different versions of the CCS compiler.

No I have only one version. Device is correct.
In MPlab you can set conf bit manually in Configure->Conf bit
or you can write it dirrectly to ROM like #ROM 0x2007 = {0x3FE4}
but I cant use derictive #fuse with MPLAB.
Strange.
Can you write line like
#fuse NOWDT,NOPROTECT,PUT
in MPLAB & compile it with CCS?
I get error Unknown keyword in #FUSES
Ideas why?

Of course I could.

but its not #fuse its #fuses. You do realize that MPLAB invokes the CCS compiler through the command line interface of the compiler. I'd suggest you post a small test program that you are trying to compile and we can look to see if anything is wrong with it. The program can be as simple as


Code:

#include <12F629.h>
#fuses HS,NOWDT,NOPROTECT

void main(void)
{
   while(1);
}

Under Configure/Select Device, what device is shown?
What version of the compiler are you using?
