1. Introduction
S1V30000 Series Graphical User Interface Seiko Epson Corporation 1
Application (Rev 3.01)
1. Introduction
1.1 Scope of Document
This document describes the PC based graphical user interface supplied with the EPSON S1V30000
Series Evaluation Kits. This provides a Microsoft Windows® based method of communicating with
application software running on EPSON’s S1V30000 series of products.
1.2 Document Outline
(1) The “User Interface Guide” is structured as follows: Section 1 provides a description of this
document and other information useful to its readers. Section 2 describes the installation of the
GUI. Section 3 gives an overview of the of the user interface, describes the communication
mechanism used and gives some general instructions on operating the user interface. Sections 4,
5 and 6 give a detailed description of the user interface starting with the main application
window, and then describing the evaluation, demonstration and reflash modes of operation.
Section 7 gives a description of the initialisation file use with the GUI. Finally Section 8 is a
trouble-shooting guide.

2. Installation
2 Seiko Epson Corporation S1V30000 Series Graphical User Interface
Application (Rev 3.01)
2. Installation
The Graphical User Interface Application (GUI) is a Microsoft Windows® based PC application, which may
be used to drive the Speech and Audio Applications on EPSON S1V30000 Series of Speech and Audio
Products.
2.1 System requirements
To run the software, a PC running under either the Microsoft Windows® 2000, XP or Vista operating
system is required.
2.2 Software Installation
The Evaluation Software should be installed as described in the Evaluation Kit Getting Started
Guide.
The exact contents of the sub-directories located within this installation directory are discussed in the
Evaluation Kit Release notes.
2.3 Launching the User Interface Application
The target hardware should be set-up and connected as described in the Evaluation Kit Getting
Started Guide before starting to use the interface. The evaluation application is launched by double
clicking the S1V30xxx_eval_application.exe file from the desktop or start menu.

3. Overview
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.

3. Overview
HOST SACC
ISC_*_REQ (REQuest Message)
ISC_*_RESP (RESPonse Message)
ISC_*_IND (INDication Message)
ISC_*_IND (INDication Message)
Figure 1 Generic Message Protocol Flow
A user action may correspond to the sending of a single message, the sending and receiving of a
sequence of messages or may require action only from the host. All messages transferred between the
host and target will be visible to the user in the system messages window.
Further details can be found in the Message Protocol document supplied with the Release.
3.3 Sequencing of user interface operations
In the case where messages are sent in a different sequence from that expected, the target will
respond with an error message which will be reported to the user in the system messages window. An
example of this is shown in Figure 2 below where the user has successfully registered the active
interface and then attempted to register again. The request has been blocked and an error code
returned. The user interface has interpreted the 0x4004 error code and displayed a message to give
the user meaningful error information.
Figure 2 Illustration of target reporting an unexpected message via system messages
In general the tabs, buttons and other controls within the user interface have been arranged so that if
the user works their way from left to right and then from top to bottom within each tab then messages
will be sent in the correct sequence to drive S1V30xxx according to its required protocols

4. Main Application Window Operation
4. Main Application Window Operation
The main application window has four lists of options to determine which setup the user will have. In general,
these four options will not have to be modified, unless changing the mode or target device. One list allows
selection of the COM port from which the user will be communicating to the evaluation board. The COM
port will only show the available COM ports, and will default to the COM port associated with the evaluation
board. The second list allows the user to select the communication baud rate. (Only two baud rates will
normally be used, 115200 for firmware update in evaluation mode, and 461000 for normal operation.) If
the firmware is being updated through the Download Scripts page, the baud rate will automatically be
reconfigured for firmware updates and normal operation. The third list allows the user to select between
running the evaluation mode, the demo mode or a reflash mode. The fourth list allows the user to select the
target evaluation device.

Application (Rev 3.01)
Once a Run Demo button has been clicked, the main application control window will be displayed with the
default tab or window selected. Section 5 describes the window and tabs in the Demonstration mode. Section
6 describes the tabs in the Evaluation mode. Reflash mode is used conjunction with Demo mode. Reflash
mode is used to reflash the firmware on the S1V30xxx devices. In Reflash mode, it is necessary to reflash the
target device before continuing on in to Demo mode.

Reflash mode. It will always be enabled when entering in Demo mode.
5.1.1.3 Reflash Button
The Reflash button first sends a reset request message
‘ISC_RESET_REQ:sending’, and receives back the message
‘ISC_RESET_RESP’. After the response, the baud rate is reconfigured to an
115200 baud rate, and the board is reflashed with the selected *.isc file in the
Script Listing Window. After the script is finished running, the baud rate is then
reconfigured to the 461000 baud rate. The previous baud rate selection is
ignored.
5.1.1.4 OK Button
The OK button closes the Download Scripts window and opens up the Demo
tabs for demonstration.
5.1.1.5 Script Listing Window/Update Listing Button
The Script Listing Window displays a list of current firmware files in the
executable directory available for download or reflashing. The update listing
button does an update of the Script Listing Window, and lists all current
firmware files in the executable directory. The Script Listing Window and the
update listing button will be disabled when in Demo mode.
5.1.1.6 Deregister Button
The Deregister button deregisters the board. When the deregister button is
pressed the messages ‘ISC_TEST_REQ:sending’ and

5.2.1.1 Speak button
The Speak button sends an ISC_TTS_CONFIG_REQ message to S1V30xxx.
This message incorporates the contents of the Language and Voice list boxes.
Upon receipt of the request message, S1V30xxx will send back an
ISC_TTS_CONFIG_RESP message to let the user know the S1V30xxx was
configured correctly.
The Speak button then sends an ISC_TTS_SPEAK_REQ message to
S1V30xxx, this message incorporates the contents of the ‘Text input for TTS’
text-box.
Upon receipt of the request message, S1V30xxx will send back an
ISC_TTS_SPEAK_RESP message. If the message displayed is
‘ISC_TTS_SPEAK_RESP : success’ the speak request has been accepted.
Otherwise please refer to the trouble-shooting guide.
Following completion of TTS processing of the text, an
ISC_TTS_SPEAK_READY_IND message will be sent. This message signals
that the TTS application is again ready to receive more input text.
5.2.1.2 Pause button
Clicking the Pause button, while text sent via the Speak button is being
processed and output by the target, will have the effect of sending an
ISC_TTS_PAUSE_REQ message, which immediately halts TTS processing,
and audio output. Success is indicated by the display of
‘ISC_TTS_PAUSE_RESP: success’ in the System Messages text-box. If other
messages are displayed please refer to the trouble-shooting guide.
Clicking the Pause button again, will send an ISC_TTS_UNPAUSE_REQ
message, which immediately start TTS processing where it left off. Success is
indicated by the display of ‘ISC_TTS_UNPAUSE_RESP: success’ in the
System Messages text-box. If other messages are displayed please refer to the
trouble-shooting guide.
5.2.1.3 Stop button
Clicking the Stop button, while text sent via the Speak button is being
processed and output by the target, will have the effect of sending an
ISC_TTS_STOP_REQ message, which immediately halts TTS processing, and
audio output.

System Messages text-box. If other messages are displayed please refer to the
trouble-shooting guide.

5. Demonstration Mode Operation
5.2.1.4 Clear Text button
The Text Input for TTS text box can be cleared at any time using the Clear Text
button located directly below it.
5.2.1.5 Insert button and drop-box
The drop-box located to the right of the Insert button contains a list of possible
foreign-language characters that might be required when inputting text in
languages other than English. It also contains emoticons and other special
characters, which can be used as inline commands to control the behaviour of
the TTS application when using the EPSON parser. To insert these characters
into the text-box, make a selection and then press the Insert button.
5.2.2 Playback Options Area
5.2.2.1 Open File button and File list-box
The list box located above the Open File button contains a list of all of the files
with a .txt extension located in the same directory as the evaluation application
executable. This list is compiled on start-up.
The Open File button causes the text within the file currently selected in the
list-box to be placed in the Text Input for TTS text box. This provides a facility
for reading text from a pre-created text file rather than typing it in directly.
Should the user wish to add their own .txt files containing input text for the
TTS application to the file list, the .txt file should be saved in the same
directory as the evaluation application executable file.
A number of example files are supplied with the evaluation kit. The languages
of the files are indicated by the ending: “en” for English, “es” for Spanish, “de”
for German, and “fr” for French. The ending “dectalk” indicates that the file
requires the DECtalk(R) parser to be enabled.
All these options can be set automatically when a file is opened by header
comments in the file, so do not need to be set by the user for the example files
supplied with the system.
5.2.2.2 Language list-box
The Language drop-box is used to specify the target language. The user has the
option of selecting U.S. English, Castillian Spanish, French, German or Latin
Spanish. The default on start-up is U.S. English.
