>Piclisters! >My next question deals with unused PIC I/O pins. Should they be made >either an input or output (software), left floating or tied to gnd or +5v? I always make them outputs. This is more flexible than making them inputs, which would require tying them to one logic state or the other. Cmos inputs left unterminated can draw lots of power, and make transitions whenever they feel like it, (Just say no) Since the outputs don't have to be tied, it's marginally less expensive, and if I have an "oops" and need a pin, it's right there waiting for me :)
