Hello all,

I've been working with PIC16F87X , 4Mhz xtal and using A/D conversion.

My A/D result is perfectly only when I use internal RC oscillator.

MOVLW B'11000001'
MOVWF ADCON0        ;Chanel 0, Frc oscillator.

I've seen the most app, using Fosc/32 or Fosc/8.
If I set this, my A/D result became crasy.
have I done something wrong?

Could you help me?

Any idea?

Regards

Luis Fernando
