From 7d0542f28045640dfab6a259ae7bd796e653d66f Mon Sep 17 00:00:00 2001 From: Doug Zongker Date: Mon, 31 Oct 2011 09:34:15 -0700 Subject: C++ class for device-specific code Replace the device-specific functions with a class. Move some of the key handling (for log visibility toggling and rebooting) into the UI class. Fix up the key handling so there is less crosstalk between the immediate keys and the queued keys (an increasing annoyance on button-limited devices).
