Find the 16F628.inc file in your PBP directory. The comment out the fuse lines with a ';'

     NOLIST
    ifdef PM_USED
        LIST
        include 'M16F62x.INC'   ; PM header
    ;    device  pic16F628, xt_osc, wdt_on, pwrt_on, mclr_on, lvp_off, protect_off
        XALL
        NOLIST
    else
        LIST
        LIST p = 16F628, r = dec, w = -302
        INCLUDE "P16F628.INC"   ; MPASM  Header
    ;    __config _XT_OSC & _WDT_ON & _PWRTE_ON & _MCLRE_ON & _LVP_OFF & _CP_OFF
        NOLIST
    endif
        LIST

Then use the config statements from Melanie.

thanks for your attention.

I did check in the .inc of the 16F628, all defined terms are there.
should i have a little bit of time to understand and figure out

thanks again

hi MACKRACKIT

it works now.

as you suggested: i change IN THE .INC FILE


IFDEF PM_USED
......

DEVICE PIC16F628 INTRC_OSC_NOCLKOUT, MCLR_OFF, ....

XALL

....

MY QUESTION IS I KEEP THE ORIGINAL INC. FILE , IN THE PROGRAM I ADD AS MELANIE SUGGESTED

@DEVICE PIC16F628 INTRC_OSC_NOCLKOUT
......

IN THIS CASE THE INC. FILE OF 16F628 SHOULD BE CALLED AND EXECUTE THE INCLUDED FUNCTION OF INTRC_OSC_NOCLKOUT AND MCLR_OFF.

BUT NOTHING HAPPENED!!!

[mackrackit]

Not sure I understand the question now.

Keep the *.inc files as Pic Basic will look for it even if it is not being used.

Most of the time I set the *.inc file the way I want the configuration to be. Others like to do it in their code.

If you set the config in code the lines in the *.inc need to be commented (rem) out, if not you will get errors.

If I understand when you were using the*.inc file nothing happened. There may be another setting in that file that was causing the problem. ??? How is MCLR set in the *.inc?

hi,

sure I have to return the orignal config. but first of all i should see how it looks like.

the MCLR was set to off (MCLR_OFF), I try another way to test the circuit in oder to bring back to the original setting.

thanks for your attention

Hi Minh LE,
Actually you do not have to return it to the default settings. The Default settings are there, mostly to help beginning programmers get started, as they likely do not know how to set them in code. You have 3 choices, return them to default settings, comment them out and always set them in your main code, or set them to the setting you use most often and do not include them in your code.

Hi, Mackrakit,

I did a mistake:

when add the @device pic16f628 intrc_osc_noclkout
and @device 16f628 mclr_off

in the conf. window should be :

1- oscillator: intrc clockout
2- Mclr input pin

-------------------------------------------------
for several ouput pins @ port B, the story is different. I am trying to read in the data sheet of the 16f628.

regards,
Minh le
