#config length ?

[cncmachineguy]

I count 76, are you sure that's the error?

You can use something like that

#CONFIG
CFG1    = _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_OFF 
CFG11   = _LVP_OFF & _CP_ON

        __config _CONFIG1, CFG1 & CFG11
        __config _CONFIG2, _BOR21V
#ENDCONFIG

cnc, it's not an error, it's just over the IDE gutter (which you can still move to whatever else but 80).

I would like to know the same thing... That is, how can one break long "__CONFIG" lines into shorter lines?

Below is an example of how to compile your program for two different PIC's, 16F1828 and 16F690. It works NOW... but getting the config statements right cost me a lot of time.

Specifically the fact that "__CONFIG _CONFIG1," works for 16F1828 and "__CONFIG" (no comma) had to be used for the 16F690.

Is the fact that some PIC's require a comma in the config line and some do not determined by MPLAB??

#IF __PROCESSOR__ = "16F1828"
    #CONFIG
           __CONFIG _CONFIG1, _FOSC_INTOSC & _WDTE_ON & _PWRTE_OFF & _MCLRE_OFF & _CP_ON & _CPD_OFF & _BOREN_OFF & _CLKOUTEN_OFF & _IESO_OFF & _FCMEN_OFF
           __CONFIG _CONFIG2, _WRT_OFF & _PLLEN_OFF & _STVREN_OFF & _BORV_25 & _LVP_OFF
    #endconfig
    #else
       #IF __PROCESSOR__ = "16F690"
         #CONFIG
           __CONFIG _INTRC_OSC_NOCLKOUT & _WDT_ON & _PWRTE_OFF & _MCLRE_OFF & _CP_ON & _CPD_OFF & _BOD_OFF & _IESO_OFF & _FCMEN_OFF
         #endconfig
           #ELSE 
           #ERROR "Program does not support " + __PROCESSOR__
       #ENDIF
#endif

If the chip only has one config word, you don't specify the word's name because it doesn't have one.
For chips with more than one config word, you must specify the word with _CONFIG1 or _CONFIG2 etc.

If you like commenting everthing really well, you can do the configs like this ...

#if __PROCESSOR__ = "16F1828"
    #config
CFG =       _FOSC_INTOSC         ; Oscillator
CFG=CFG&    _WDTE_ON             ; Watch Dog Timer 
CFG=CFG&    _PWRTE_OFF           ; Power-on Timer
CFG=CFG&    _MCLRE_OFF           ; Master Clear Reset
CFG=CFG&    _CP_ON               ; Code Protect
CFG=CFG&    _CPD_OFF             ; EEPROM Data Protect
CFG=CFG&    _BOREN_OFF           ; Brown-out Detect
CFG=CFG&    _CLKOUTEN_OFF        ; FOSC/4 Output
CFG=CFG&    _IESO_OFF            ; Internal External Switchover
CFG=CFG&    _FCMEN_OFF           ; Fail-Safe Clock Monitor
   __CONFIG _CONFIG1, CFG
 
CFG =       _WRT_OFF             ; Flash table writes

CFG=CFG&    _STVREN_OFF          ; Stack Over/Underflow
CFG=CFG&    _BORV_25             ; Brown-out voltage
CFG=CFG&    _LVP_OFF             ; Low Voltage Programming
   __CONFIG _CONFIG2, CFG
    #endconfig
#else
    #IF __PROCESSOR__ = "16F690"
    #config

Hi:
Thanks Steve, it works now !.

Still doable the long way, still easy though

       ASM                  
                          
       __CONFIG _CONFIG1, B'11111101010100'

Not too hot with that method, but neat
