unused switch pins
Posted: Wed Dec 09, 2015 1:07 pm
is there a best practice when it comes to unused switch pins? should I tie them to ground via 10k resistor or to 3.3v? or does it make no difference (other than the program number)
Yes, S0-2 tied to ground will select program 0,tjm215 wrote:so if i tied all to ground would that select program 0?
