3. Overview

3.1

Main components of the user interface

The user interface is composed of two windows; a

main application window

used for setting up

communications with the target and an

application control window,

which enables the user to interact

with the applications software running on the target. The

application control window

also refers to

the Download Scripts window in Demo and Reflash modes.

The application control window takes one of three forms depending on which of the three modes;

Evaluation, Demo and Reflash Mode is selected. The Evaluation mode is made up of seven tabs;

Configuration, TTS, ADPCM, Playback-Stream, File Transfer, Scripting,

and

I2S

. The Demo mode

is made up of two tabs;

Multi-lingual Text-to-Speech

and

Audio Decode

. The Reflash Mode is similar

to the Demo mode, except it allows the firmware to be reflashed. Not all applications are supported

on all target products, so fewer tabs may be displayed, depending on the chosen target device.

The application control tabs contain a variety of file-views

text-boxes, drop-boxes, data-fields and

buttons. Parameters are selected using the drop-boxes and data-fields, and buttons are used to send

commands to the target in the form of messages. The parameters selected at the time that the button

is clicked are transferred to the target as part of these messages.

3.2

Common system message display

The PC communicates with the S1V30000 Series Chip via the messaging protocol described in the

Message Protocol Specification.

All messages sent to or received from the evaluation board are reported to the user via the

System

Messages

Display

text-box of the currently active tab. This display, and the information it contains,

are common to all tabs and are always shown in the currently active tab.

All messages have an ISC message identifier, which determines its contents as well as which one of

the three basic types it belongs to: request, response or indication message. Figure 1 below shows the

generic message protocol, based on these ISC messages, which is used to communicate with the

target.
