    yup but, you really need to connect all Vdd and Vss, unless, it will give you some strange things... or simply don't work.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    ibra,

    Did you look at the schematic on the link I posted above?

    Thumbs up

    Code:
            @ __CONFIG _XT_OSC & _LVP_OFF
        PORTB = 0
        TRISB = %11111110

MAIN:
        TOGGLE PORTB.0
        PAUSE 200
        GOTO MAIN
