6.1 Introduction to playlist mode operation
When the fl ash memory is inserted, the DMA1 analyses its content to
defi ne its mode of operation based upon the fi les present:
1. File: PLAYLIST.TXT plays audio fi les in sequence according to the
list present in the fi le
2. File: 1.M3U, 2.M3U, 3.M3U, 4.M3U, 5.M3U, 6.M3U, 7.M3U plays
audio fi les in sequence according to the list present, activated
by logic input
IN1 = 1.m3u IN2 = 2.m3u IN3 = 3.m3u IN4 = 4.m3u
IN5 = 5.m3u IN6 = 6.m3u IN7 = 7.m3u
During play the four command buttons REW, STOP, PLAY and FWD
are active.
6.2 What is a playlist fi le?
The DMA1 is able to follow a sequence or list of audio fi les; this play list is
a simple text fi le called playlist.txt which can be inserted in the main
directory of the same memory containing the audio fi les.
Follow a few, easy rules to set the sequence:
Example 1 Example intro
with 3 with part 1
numbers: 7 names: part 2
9 monologu
5 music
01 part 3
005 fi nale
IMPORTANT!
• Rename the MP3 audio fi les with numbers or names with
8 characters max.
• Do not write in the extension (.mp3)
• Max. 500 MP3 fi les per playlist
Insert the fl ash memory card and wait for the DMA1 to read the playlist.
At the end of the reading operation, if the names of the pieces have been
fi tted in correctly, the DMA1 will automatically start to play the MP3 fi les in
the programmed sequence or wait the activation of a logic input.
6.3 Playlist activation by logic inputs - MPLL (Mode PLayList)
parameter
The seven available playlists activated by the logic inputs, can be played
with different modes depending upon the varying needs.
To choose between the different modes of operation the confi guration
parameter MPLL (Mode PLayList) must be defi ned in the confi g.txt fi le.
When the fl ash memory card is inserted, the DMA1, depending on the
setting of the parameter MPLL in the fi le confi g.txt, will switch over to the
relevant mode of operation.
IMPORTANT!
• The names of the 7 playlists are fi xed
• The loading times of the Playlists may last even tens of seconds,
during which the DMA1 is not able to play
