Presetting Configuration Fuses (PIC Defines) into your Program

[Tissy]

Yup, that cleared it up, thank you.

Also where can i download MPASM ver 5.00. I've looked at Microchips site but can't find the link. Do you have it by chance?

Thanks again,

Steve

[Tissy]

I had it all going in version 4.01 of MPASM and then downloaded version 5.00....big mistake !!

Now i am getting all sorts of errors. If i use no config fuses in the code and set them manually all compiles fine, but when i try and set the fuses, errors occur again.

I have done what is suggested above and commented out the necessary lines in the 18F2550.INC file found in the PBP directory.

Any suggestions?

[Tissy]

Sorry, to clarify, it does seem to compile, but i get this error:

Warning[230]c:\develo~1\susdco~1\rfusb~1.asm 67:__CONFIG has been deprecated for PIC18 devices. Use directive CONFIG.

This error is repeated a number of times.

[Tissy]

Nope, still getting stacks of errors.

Here is exactly what i have at the tope of my code:

' ---------- [ Configuration fuse ] ----------
@ CONFIG PLLDIV = 5, CPUDIV = OSC1_PLL2, USBDIV = 2
@ CONFIG FOSC = HS
@ CONFIG WDT = ON, WDTPS = 128
@ CONFIG PBADEN = OFF
@ CONFIG LVP = OFF, ICPRT = OFF, XINST = OFF  

'@ __CONFIG    _CONFIG1L, _PLLDIV_5_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_2_1L
'@ __CONFIG    _CONFIG1H, _FOSC_HS_1H
'@ __CONFIG    _CONFIG2H, _WDT_ON_2H & _WDTPS_128_2H
'@ __CONFIG    _CONFIG3H, _PBADEN_OFF_3H
'@ __CONFIG    _CONFIG4L, _LVP_OFF_4L & _ICPRT_OFF_4L & _XINST_OFF_4L


Clear
DEFINE OSC 20

The necessary lines are commented out in the .INC file as suggested.

The .INC file in the MPASM directory is untouched.

Any other ideas?

If using 18F Parts...

Check this answer by Bruce...

... if you're not using 18F Parts and you're getting this message - you're in deep trouble.

Hi Melanie,

I've read Bruce's post, I've read Mr.E's posts and I've read everyone else's posts about having problems using the new CONFIG syntax.

Then after trying to implement those ideas, I find that it's just not worth it.

I prefer the configuration methods as laid out in your original posts in this thread. The way that it's always been, and the way my programs are already written. And, since there's currently NO reason to use the new syntax, I wanted everyone to know that they don't have to go thru what I just went through.

Simply turn off the warnings, and forget about it. (for now)

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

it works here...

[Tissy]

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]

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.

        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.

[ScaleRobotics]

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]

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?

[ScaleRobotics]

Hi Bruce,

I had it in some earlier code, but you are right it is missing here. That brings me back up to what appears to be 12 x the 4 mhz default speed (that is 12x faster than PBP is expecting it, since I am missing the define to make it compile), when I leave out my oscillator define. But when I put in my DEFINE OSC XX I get the same error as before.

[Bruce]

I'm guessing you still have the new config directives in your code VS in the 18F26J50.INC file?
That will cause the error. You need to place these in your 18F26J50.INC file.

Then it should work as expected.

[ScaleRobotics]

Thanks Bruce,

The configs work. My configuration fuses get changed properly, my led blinks. However, PBP can not accept the speed of my oscillator. It looks like the only thing that needs to be done is to have MeLabs make some sort of change on their end to accept the OSC speed.

[Bruce]

Hi Walter,

Are you setting OSCTUNE.6 to enable the 96MHz multiplier?
