Summary: Power on/off slaved to external power
Initial Comment:
Using the Rockbox in a vehicle would be enhanced by
allowing the presence of power on the DC IN/charger
port to control the on/off status of the Rockbox.
Auto-off:
The unit should store a bookmark at the current playing
position (as is done currently with a manual shutoff) and
shut off when power is removed from the DC IN port
(corresponds to vehicle ignition off). It seems that this
is feasible, looking at the code in powermgmt.c.
Auto-on:
When power is reapplied to the DC IN port
(corresponding to vehicle ignition on), the unit should
automatically power-up. The resume mode (as
currently implemented) should determine if the unit
begins playing automatically or prompts the user to
continue. I'm not sure if this is feasible, but it seems
like the unit can detect charger insertion (the recorder
shows the "Charging ..." screen and charging is
currently controlled by software on the recorder), so this
might be possible.
Notes:
The Auto-off feature is much more important than the
Auto-on feature. It is easy to forget to turn the unit off
when leaving a vehicle, possibly draining the batteries to
full discharge unintentionally. Also, any hope of
bookmarking your location is lost if the unit keeps
playing without anyone in the vehicle. Auto-on would be
great, but I'm much more likely to remember to turn the
unit on when I start driving (the silence from the vehicle's
audio system is a dead give-away that I've forgotten to
do something).
Additional features:
This option must be configurable.
It would be nice if a configuration file could automatically
be loaded when playing on external power vs. playing on
internal power. This would allow a "Vehicle.cfg" file to
be selected automatically when plugged into the vehicle
power; a "Battery.cfg" could be loaded for internal power
use. This would allow settings to be automatically
changed to support the use of the vehicle sound system
vs. headphones (less bass boost needed in the vehicle,
for instance), font changes (bigger font, less lines
desired in the vehicle), and even eventually default
playlist selection (driving music in the vehicle, maybe
even to the point of selecting a morning drive-to-work
playlist in the AM and a thankfully-the-day-is-over
playlist for the trip back home in the PM).
