Presetting Configuration Fuses (PIC Defines) into your Program

**mister_e** · - 30th October 2005, 11:01

Tissy... are you saying that modifying and saving your C:\PBP\18F2550.INC as follow

Code:

         CONFIG EBTRB = OFF         ; Boot Block Table Read Protection Disabled
    ENDASM

it works here...

Yup, affraid so. I have just comapared the .INC file to yours, exactly the same.

I have also copied your ASM section to my code and it still produces a stack of errors.

Any suggestions?

**mister_e** · - 30th October 2005, 13:14

OK, i also have the same problem here.. hum hum when i add some code line as you did.

SO it looks like PicBasic is not "New MPASM Compliant" for the config fuses. I'll contact Charles tomorrow.

For now, what you can do is to place your config fuses in the 18F2550.INC in the PBP folder. BUT if you do different project and you need different config fuse setting, You can add a device to the MCS list and create a new .INC and .BAS file for it. OR do an include file to be loaded in the 18F2550.INC file.

Code:

        NOLIST
    ifdef PM_USED
        LIST
        "Error: PM does not support this device.  Use MPASM."
        NOLIST
    else      
        LIST
        LIST p = 18F2550, r = dec, w = -311, f = inhx32
        INCLUDE "P18F2550.INC"	; MPASM  Header
        INCLUDE "C:\PBPProg\ConfigFuse.cfg" ; Your Config Fuses
        NOLIST
    endif
        LIST
EEPROM_START	EQU	0F00000h
BLOCK_SIZE	EQU	32

Just drop your config lines in the ConfigFuse.cfg file and it's work... this time. DOH sorry.

Thanks for that. I thought i was going mad !! Theres nothing worse than people saying it should work when it doesn't. You have save my insanity.

I think the .CFG approach is a good solution.

Many thanks,

Steve

hi,
i also facing similar problem if i try to compile programe on 18f452 i get the similar message like:
Warning[230]c:\develo~1\susdco~1\rfusb~1.asm 67:__CONFIG has been deprecated for PIC18 devices. Use directive CONFIG.
i am using pbp2.44 with mpasm7.21.
I tried to rectify the problems with the above directives but fail should i go for the other version of mplab
pl. help
thanks

**Tissy** · - 30th October 2005, 23:54

Havin gtaken the .CFG route, Steve does yours come up with these errors?

Code:

Warning[205] c:\pbp\sdcconfigfuse.cfg 1 : Found directive in column 1. (CONFIG)
Warning[205] c:\pbp\sdcconfigfuse.cfg 2 : Found directive in column 1. (CONFIG)
Warning[205] c:\pbp\sdcconfigfuse.cfg 3 : Found directive in column 1. (CONFIG)
Warning[205] c:\pbp\sdcconfigfuse.cfg 4 : Found directive in column 1. (CONFIG)
Warning[205] c:\pbp\sdcconfigfuse.cfg 5 : Found directive in column 1. (CONFIG)

Could you post your .CFG file?

Cheers

**mister_e** · - 31st October 2005, 07:18

The CFG file is the one i post few post before. You just need to Indent your CONFIG lines as i did.

**ScaleRobotics** · - 16th June 2010, 22:03

Ah, I see what you mean!

Code:

Define XTAL 48
OSCTUNE.6 =1
ASM
   CONFIG OSC=HSPLL

**SKOLS1** · - 2nd August 2011, 23:08

I got this error: overwriting previous address contents (2007)
I write this line @ __CONFIG _INTRC_OSC_NOCLKOUT to turn on the internal oscilator of the PIC16F628A,
I fix any mistakes what I think I made them,but there are errors.I DEFINE OSC 4,it's not working.

**ScaleRobotics** · - 16th June 2010, 21:54

Thanks Bruce, that does the trick! Just did exactly as you said, and now it lets me compile inside my program code like this:

Code:

Define XTAL 48
OSCTUNE.6 =1
ASM
   CONFIG OSC=HSPLL 
   CONFIG CPUDIV=OSC1
   CONFIG PLLDIV=5
   CONFIG LPT1OSC=OFF 
   CONFIG CP0=OFF 
   CONFIG WDTEN=ON 
   CONFIG XINST=OFF 
   CONFIG IOL1WAY=OFF
   CONFIG STVREN=OFF 
   CONFIG T1DIG=ON 
   CONFIG FCMEN=OFF 
   CONFIG WDTPS=512
   CONFIG RTCOSC=T1OSCREF
ENDASM

And my LED is blinking at the right speed. Yes, I could just edit configs in the .inc file, but then you have to change it for each project. A pain if you want to jump around from unfinished project to unfinished project. Oh, that's just me....

**Bruce** · - 16th June 2010, 21:59

Cool. Maybe the fix is something as simple as melabs changing to something other than OSC?

Just bear-in-mind that your next PBP update will change everything, and any patch will fail since you've modified your library files...;o)

**ScaleRobotics** · - 16th June 2010, 17:48

Yes, I do. My question sort of was:

Is there a work around. Sounds like the answer is NO for the newer chips that do not have the CONFIGxL/H in their .inc file.

Which brings me to my next question:
Since it appears that the only hang up is the way PBP checks to see if you can run at the processor speed, do you think this can be fixed pretty easily by MeLabs? Or do you think I am making it out to be easier than it really is. I have tried to do a work-around, but have not succeeded (yet).

It is not such a big deal, as I can declare them as you suggest. But I am stubborn, and it appears to be one single register that needs to be set, and it would work.

**Bruce** · - 16th June 2010, 18:51

I'm not sure what the fix would be to be honest, but if you're up for an experiment, try this;

Make a backup copy of your PBPPIC18.LIB.

Now use an editor to find & replace all instances of OSC with XTAL.

Save the .LIB file, and compile with DEFINE XTAL 48, and the new config directives in your code.

Does it work?
