External memory organisation

The STM32100B-EVAL demonstration is based on an embedded free FAT file system,
(1)
DosFs
MicroSD memory card.
The SD card memory is organized in two sub directories:
●
STFILES: this folder contains all needed demo media files (icons, wave and slides).
User files located in this folder cannot be handled by the demonstration, only default
files are managed. The STFILES directory and its internal files are mandatory for
demonstration startup.
●
USER: this is a user folder. You can add here your 16-bit bitmap images (320x240) and
waves. This folder is used only by the Images Viewer and Wave Player submenus. For
more details on the different files properties, please refer to
Viewer submenu
1. The DosFs is a FAT-compatible filesystem intended for fairly low-end embedded
applications. It is not the leanest possible implementation (the leanest FAT
implementations operate in << 512 bytes of RAM, with heavy restrictions). This code
strikes a good balance between size and functionality, with an emphasis on RAM
footprint. For more details, refer to the following link
