4 - Operating the player and naming of files
The GeoPlayer reads files and playback instructions stored on the SD memory card. No extra software
is required to configure the player. Playback options are provided by the way files are named and
organized in the directories.
There are two categories of files:
1 - Files to be played on powering on the player and played back in loop.
2 - Files to be played on GPS position detection.
These 2 categories of files are represented by 2 directories or folders. Naming of directories results in
various playback options.
A configuration file «gps.csv» must also be copied at the root of the SD card ; this file contains the
various GPS positions and associated information (see details in chapter 5).
Example of use:
On powering on, one or several files are played and loop (background music for instance). When GPS
location is reached, the looping files stop and the audio file associated to the GPS location is played;
after playing the triggered file, the loop file is played again.
4.1 Organization of the two directories:
Only one level of directory is allowed at the root of the memory card. Two directories only are permitted.
Directory names are composed of 2 meaningful characters.
Exemple : «0R» or «0S» and «GPS»
4.1.1 Directory «0x»
Place in this directory audio files to be played in loop on powering on the player. When the player is
powered, presence of this directory is checked. If it is found, all the files are played. If it is not present
on the SD card, the player goes to standby mode and awaits for a GPS input.
The maximum number of files in this directory is 250.
