External memory organization

The STM32303C-EVAL demonstration is based on an embedded free FAT file system,
FatFs. The file system is needed to read all media information from the on-board MicroSD
card memory. The MicroSD card memory is organized in three subdirectories:
● STFILES: this directory contains all the required demonstration media files (icons).
User files located in this folder cannot be handled by the demo; only default files are
managed.
●
USER: this is a user folder. The user can add his/her own files here to be played inside
the demonstration menus (pictures and waves). This folder is used only by the Image
Viewer and Wave Player submenus. For more details on the various files properties,
please refer to
features.
Caution: The STFILES directory and its internal files are mandatory for demonstration startup. FatFs
is a generic FAT file system module for small embedded systems. The FatFs is written in
compliance with ANSI C and completely separated from the disk I/O layer. For more details,
refer to the following link: http://elm-chan.org/fsw/ff/00index_e.html.
