Hi

I'm a beginners with the pic 16F84 and I've got a problem. With a switch
connected to RA0, I'm trying to switch on a led connected to RB1 and
switch off another one connected to RB6 for a switch position ans switch
Off RB1 and siwtch on rb6 for the other position.

The case where RB1 is on and RB6 if off is ok, but the other case the 2
leds are on with a voltage of 2v5 instead on 5v.
