Config problem PIC16F886

[skimask]

@ __CONFIG _CONFIG1, _INTOSCIO & _WDT_ON & _PWRTE_ON &_MCLRE_ON & _LVP_OFF & _CPD_OFF & _FCMEN_OFF & _IESO_OFF

Anything below this line isn't going to have an effect on your CONFIG fuses.
They are 2 separate entities...
And when I said read back, I meant the actual config word data as read back using the PICKIT2, not the data you are trying to push out to the PIC using the programmer.

EDIT: Just checked your CONFIG against the '886/887 datasheet. When reading back the PIC after programming the config word, you should readback $E3ECFFFF, if it's actually being programmed to those values.

If I had an '886, I'd try it to see what I get.
Oh...wait...I've got the demo board with an '887 on it.
When I get a chance, I'll see what it reads...

Will be very greatful for your help, can see that 16F887 have exact the same CONFIG words.
Have used 16F876A before without problems, but they dont have internal oscillator.

Do you have the actual PICKIT2 or a knockoff?

Forgot to add...did you get the demo version with the demo board with the '887 (or maybe '917) on it?
