From 38d4110e59a44687d8a4743b8cd04cbf2761c9d8 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Sun, 28 Apr 2013 23:08:03 -0700 Subject: altos: Allow LCD segments to not be multiplexed across digits This allows each LCD segment to be individually configured as to which COM and which SEG drives it, permitting maximum flexibility in wiring.
