From d03cf2b83f9df6b802af72860d8d3b56df89956f Mon Sep 17 00:00:00 2001 From: Kevin O'Connor Date: Wed, 11 Oct 2017 22:16:02 -0400 Subject: adccmds: Continue to query analog inputs after a shutdown Continue to sample the ADC input pins even if the MCU goes into a shutdown state. This enables the printer to continue reporting temperatures even on an mcu error.
