I keep getting asked to build an EC image to manually control the lightbar patterns so that the Powers That Be can look at it. This change just makes it possible to turn that mode on and off for yourself. You'll need a root shell or the EC console to do it, though. BUG=chrome-os-partner:8039 BRANCH=link TEST=manual From the EC console, type lightbar demo 1 OR from the root shell run ectool lightbar demo 1 After that, these keys should change the lightbar appearance (transitions may be slow and subtle - that's intended): UP = battery is more fully charged DOWN = battery is less fully charged RIGHT = battery is charging LEFT = battery is discharging BRIGHT = increase lightbar brightness DIM = decrase lightbar brightness Note that this does not interfere with the normal function of any keys. It only adds some additional EC behavior.
