Hi PICsters,

I have a 12 position single pole rotary switch that I'd like to interface to
a 16F84 and I don't have 12 spare IO pins ;) (Ideally I'd like to use 4 pins
or less). I've seen examples of using a resistor lader and an RC timer
circuit (uses too much cpu time for my purposes), presumably there's also a
logic chip (demux?) that will do the job, I'm just wondering if I've missed
any other obvious, minimal, and/or clever solutions to this problem.

Thanks in advance.

Ross B.
