Another 2.60 worry

[muddy0409]

Hi everyone, me again with another question concerning PBP 2.60

2.60 Doesn't seem to like the following config stuff

@ DEVICE pic16F886, HS_OSC ' System Clock Options
@ DEVICE pic16F886, WDT_OFF ' Watchdog Timer
@ DEVICE pic16F886, PWRT_ON ' Power-On Timer
@ DEVICE pic16F886, BOD_ON ' Brown-Out Detect
@ DEVICE pic16F886, LVP_OFF ' Low-Voltage Programming
@ DEVICE pic16F886, CPD_OFF ' Data Memory Code Protect
@ DEVICE pic16F886, PROTECT_OFF ' Program Code Protection
@ DEVICE pic16F886, WRT_OFF ' Flash Memory Word Enable

I have read through the Melabs blurb on config (Specifying configuration bit settings in PICBASIC PRO™ programs.)
but can't get my head around the waffle.
It's obviously written by geeks for other geeks to understand.
Not being a geek I just can't understand any of it.

So can anyone translate the above listing into a 2.60 config statement.

I don't necessarily want to know what it all means, I just want a statement that works and that I can use over and over.
I generally use the same Pic type for most things so a standard version of the above would be great.
_CONFIG_ SOMETHING OR OTHER

Thanks again,

Hi,
There IS a standard, basic, working most of the time configuration fuse setting already setup for each and every chip that the compiler supports. You don't have to set them in your code if the default is OK.

If you wan't to see how they "work" and what they are simply open the .inc file for the specific target you're compiling for, it's located in the root of the PBP folder. For the 16F886 the fileneme is 16F866.INC and looks like this:

        NOLIST
    ifdef PM_USED
        LIST
        include 'M16F88x.INC' ; PM header
        device  pic16F886, intrc_osc_noclkout, wdt_on, mclr_on, lvp_off, protect_off
        XALL
        NOLIST

    else

        LIST
        LIST p = 16F886, r = dec, w = -302
        INCLUDE "P16F886.INC" ; MPASM  Header
        __config _CONFIG1, _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_ON & _LVP_OFF & _CP_OFF
        NOLIST
    endif
        LIST

Now, the @ DEVICE statement is used when you're using PM as the assembler and the __CONFIG (note two underscores) is used when you're using MPASM as the assembler. If you're Win7 you can't use PM which means you're using MPASM which means @ DEVICE is the wrong "command".

In order to find out the "names" of the various fuses go to your MPASM folder and open the P16F886.INC file, at the end of that file you'll find this:

So, to change the CONFIG fuses you have two options:
1) Edit the 16F866.INC file in the PBP folder to have the CONFIG you want/need. Do make a backup of the original file first.
2) Comment out the CONFIG from the 16F866.INC file and instead put them in your code.

Rightio, I opened the M16f88x.inc file in the PBP directory.
That first example you gave does not exist anywhere in the file??
This is getting all too hard..I'm gunno go play soliraire.

I do understand that I can edit the first example you gave and make it into a new default that suits me.
But, as I said, it ain't in there.

Hi Muddy,

Not those Mxxx inc files, these 16f886.inc files . Check here: C:\PBP\

[HenrikOlsson]

Ah, come on now Peter...

If you wan't to see how they "work" and what they are simply open the .inc file for the specific target you're compiling for, it's located in the root of the PBP folder. For the 16F886 the fileneme is 16F866.INC and looks like this:

Why did you go open the M16F88x.inc ? (I don't even have that file on my system.)

It's not THAT hard...but you have to actually read ;-)

[muddy0409]

Aah, there it is. I didn't look through the whole directory, did I?
So If I change
__config _CONFIG1, _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_ON & _LVP_OFF & _CP_OFF
NOLIST
endif

to

__config _CONFIG1, _XT_OSC_NOCLKOUT & _WDT_OFF & _MCLRE_ON & _LVP_OFF & _CP_OFF
NOLIST
endif

that should then make the default suit my preference? And I shouldn't need to do a config with any new programs, unless I want or need to change them?

Thanks Man.

[muddy0409]

after a bit more experimentation....should be

__config _CONFIG1, _XT_OSC & _WDT_OFF & _MCLRE_ON & _LVP_OFF & _CP_OFF
NOLIST
endif

[HenrikOlsson]

Yep, looks good to me. As you can see, the different configuration settings for the oscillator (and everything else) are at the bottom of the P16F886.inc file (the one in the MPASM folder):

_LP_OSC                      EQU     H'3FF8'
_XT_OSC                      EQU     H'3FF9'
_HS_OSC                      EQU     H'3FFA'
_EC_OSC                      EQU     H'3FFB'
_INTRC_OSC_NOCLKOUT          EQU     H'3FFC'
_INTRC_OSC_CLKOUT            EQU     H'3FFD'
_EXTRC_OSC_NOCLKOUT          EQU     H'3FFE'
_EXTRC_OSC_CLKOUT            EQU     H'3FFF'
_INTOSCIO                    EQU     H'3FFC'
_INTOSC                      EQU     H'3FFD'
_EXTRCIO                     EQU     H'3FFE'
_EXTRC                       EQU     H'3FFF'

On the 16F886 there are two CONFIG words (on other chips there are more) so if you need to change something that resides in another CONFIG word you have to add a second line, like

   __config _CONFIG2, WRT_HALF & _BOR21V

Then you have your defaults and it is what will be included in every program you compile for that particular target, no need to have them in your code if you don't want to.
