Configuration
When a resource file like an icon, logo or sound file is searched
for, the resource is searched for on the SD card and then internally.
That means that a resource file with same name, both internally and
externally, is taken from the SD card. The SD card has the highest
priority.
It is not necessary to include the file extension in the resource
names. Remember that the Linux ® file system do care about if letters
are capital or not, meaning that “File.txt” is not the same as “file.txt”.
Icons and logos must be standard “PNG” files, 16 bit colour depth.
Sounds must be either wave files 16, 22.05 or 44.1 kHz sample
rate, and 8-16 bit mono/stereo, or MP3 files with bitrate 64-256 kbit
mono/stereo. If using MP3 files: recommended bit rate is 128 kbit.
External resources (SD card)
Customer/user files on the SD card used for icons, logos and speech
announcements, must be placed according to requirements below.
Resource files
Icons and logos
Icons and logos are all placed in sub folder “/PIC/”.
Sound files
All sound files are placed in sub folder “/WAV/”.
Optional music files are placed in “/WAV/MUSIC/.
Music files requirements
The music files are all stored in “/WAV/MUSIC/” folder.
All files in this directory are played in a loop as long as
the music is enabled. Don’t install one large music file
with all the music. Divide the file in natural segments
or melodies. Keep the size of the individual music files
smaller than 20 MB.
