> i can't congifure ADCON1 and so the port configuration for > vref+ and the analog channels etc, can't be made How are you looking at this to be able to say that you can't access Bank1 ? For example is MPLAB (or whatever it is you're using) not working in simulation or are you actually programming the PIC and it doesn't do what it's supposed to ? Tried another PIC ? > yes, i have everything configured as it should be Does that include TRIS ?
