Lisa LCD

The first time the Lisa starts up and after a reset to
default settings, the Lisa will ask the user to choose
default source to play from. The choice is between
Internet and Card and according to the input from the
user, the Lisa will start to play from the chosen source.
8.2.2
Play from Internet
The Lisa plays from the internet when it was the last used source, or if the user chooses internet as
source.
The Lisa will try to retrieve from the last saved settings which preset
was being played the last time. When the last played station is valid,
the Lisa will start to play from internet.
When the last-played preset is not known or not valid anymore, the
user is asked to choose.
If the user does not make a choice within 10 seconds, the station
which is shown on the LCD is automatically chosen.
8.2.3
Play from SD card
The Lisa can play playlists from the memory card. A playlist is a text file with the “pls” extension, which
contains a list of songs (referred to as entries). See
section describes how the Lisa plays from SD card when
There may be many playlists on the card each with a number of entries. When the device has to play
from card it needs to know where to start. It need to know which playlist it should start playing and from
which entry.
The Lisa starts playing where it left off last time. Every time you ‘stop’ playing from card, or when you
power off the device or switch to internet, the Lisa will save the id of playlist it was playing. We call this
the Last Played Playlist. The Lisa will also save the ID of the entry it was playing, which is called the
Last Played Entry.
When Last Played Playlist and Last Played Entry are known, the next time it plays from card, the Lisa
will know exactly where to start.
The Lisa does not always know the Last Played Playlist and Last Played Entry. When Last Played
Entry is not known, the Lisa will start to play the playlist from the first entry. In case the Last Played
Playlist is not known, the user is asked to make the choice between the available playlists. This is
called the selected playlist (SP).
