the Microsoft® FAT file system) and the interpretation of these file sys-
tems is provided by the registration of another type of device driver
termed a file system driver (FSD).
Users who wish to provide additional or replacement FSDs and PIDs for
either file system or physical interface support can do so simply by follow-
ing a set of design rules for the appropriate class of device driver and
registering that driver with the FSS upon application initialization. Please
refer to "Extensibility" on page 12-83
The file system service is designed to function in both standalone and
RTOS environments. To this end, several examples are available with
VisualDSP++ 5.0 to demonstrate the configuration and use of the FSS.
One particular example, the shell browser example, is a multi-threaded,
VDK-based application that presents a simple, command-line interface to
the file system service on a terminal emulator connected to the UART
interface of the ADSP-BF548 EZ-KIT Lite. Details of these examples are
provided in "Examples" on page
Getting Started
The basics for initializing and using the file system service within an appli-
cation are outlined in this section. It is assumed that the system services
and device manager have already been initialized. The dependencies on
the system services resources are detailed in
ments" on page
This section describes the overall operation of the file system service. A
more complete description of the application programming interface
(API) can be found later in this chapter.
