#config...#endconfig

Got to
C:\PBP3\DEVICE_REFERENCE
and find the file for you chip.

But the (') in your config statement might be causing some of you trouble.

thanks,
that helps a lot seeing where they are located as a reference
but...
CONFIG WDTE = OFF
still gives "CONFIG directive Error: (setting "WDTE in the supplied MicroCode IDE.

both ON and OFF give the same error for my 18f6722 chip.

[mackrackit]

Try this
#CONFIG
__CONFIG _CONFIG1H, _OSC_HS_1H & _FCMEN_OFF_1H & _IESO_OFF_1H
__CONFIG _CONFIG2H, _WDT_ON_2H & _WDTPS_512_2H
__CONFIG _CONFIG4L, _STVREN_ON_4L & _LVP_OFF_4L & _BBSIZ_BB2K_4L & _XINST_OFF_4L

#ENDCONFIG

thanks,

Yes that compiles OK
I turned the WDT off though. don't know what the other options are....

where can I get the reference on these options? they don't look like the ones in the INFO file.
what is the CONFIG1H through CONFIG4L about. Is that something in the microchip files?

[mackrackit]

To get the complete or correct configuration information you need to look at the, for this chip, P18F6722.INC file. This is in
C:\Program Files\Microchip\MPASM Suite
Do not modify this file, the info is near the end.
The CONFIG1H through CONFIG4L is just different places the various bit are stored.

I usually try to turn off as much stuff as possible. I figure they cost overhead that I could use for my own program instead.

Then I turn features on as I need them 'cause I often turn off too much stuff.

EDIT: Maybe this might shed some light on features:

A config bit is either on or off, but it is still a bit.

A config bit is either on or off, but it is still a bit.

I know, but don't features generate more code if they are active?

PWM, USB, etc.

EDIT: An example of unnecessary overhead:

ADON: ADC Enable bit
1 = ADC is enabled
0 = ADC is disabled and consumes no operating current

I rarely use ADC, apparently having it on for nothing would consume current needlessly (probably very little, but still).
