Config problem PIC16F886

[Bosse]

Hi Darrel,

Always get a lot of messages that the config is not correct.

Now I have decided to use Crystal and will be very greatful for help with configuration word(s)

Have used a PIC16F876A before without any problem, think it can be that the F886 have 2 config words????

[Darrel Taylor]

Are you using the default PM assembler, or MPASM?

For PM, the CONFIG2 word is set using the DEVICE2 pseudo-op. But not setting config2 will not cause an error. And your DEVICE line above looks OK (if using PM).

If you are using MPASM then it would be ...

@    __config _CONFIG1, _INTOSCIO & _WDT_OFF & _MCLRE_OFF & _LVP_OFF & _CPD_OFF & _FCMEN_OFF &  _IESO_OFF

Of if you're using a crystal now, replace _INTOSCIO with _XT_OSC or _HS_OSC.

Don't forget to comment the config line in the 16F886.inc file in your PBP folder.

Hi Bosse:
If you are using the port A as digital, you will need to disable too the
comparators.
CM1CON0 = 0
CM2CON0 = 0

Thank you very much Darrel and Ruben,

I use PM assembler. Have decided to use a ceramic resonator (20 MHz)

Wants ALL DIGITAL if possible.

Will try your configuration recommendations

Thanks again

Hi,

Now I have done something ?????

Get the error: Error 16F886.INC 15 : [201] ''' expected

Have changed the INC file, but changed it back to original again, so now when I try to compile get this error.

Use PM and PicBasic Pro with MicroCode Studio Pro.

Please is there anybody how can help me solve the problem

Hi Bosse,
Can you post your .inc file, at least the area where you been pokin' around ? Also post the first say 8 - 10 lines of the code you are trying to get to work?

Hi Joe,

First I tries to get Config O.K. so have only a small program for testing config words. Wants ALL digital. Working with a project with MAXIMS iButton chips, works perfect with 16F88.

Think the INC file is O.K - But can not understand why it stops working????

'@ DEVICE PIC16F886, INTOSCIO, WDT_ON,MCLR_OFF,LVP_OFF,PROTECT_OFF,BOD_OFF,CPD_OF F,IESO_OFF,FCMEN_OFF,PWRT_ON

'DEFINE OSC 8

OSCCON = %01110001 ' Internal 8 mhz Osc
ANSEL = 0 ' All Digital
ANSELH = 0
'ADCON1 = $0F
'ADCON0 = 0
TRISC = 0

RUN:
PORTC.0 = 1
pause 1000
PORTC.0 = 0
PAUSE 1000
goto RUN
END

Do you recomend to use MPASM assembler? Have now tried more than 2 weeks with this problem.
PORTA is reserved for furure use - PORTA.1 = Input
PORTB %??001111 - RB6 and RB7connected to progsocket for PicKit2.
PORTC %11100100 - RC3 = SCK - RC4 = SDA 24LC256

Would be very great ful for all help and advices

Thanks in advance
