Quick start guide
This document presents important information about your new professional audio development kit (or
PADK). Read it thoroughly before going any further.
Introduction
Congratulations on the purchase of your professional audio development kit (or PADK). The PADK is
completely compatible and integrated with Code Composer Studio and eXpressDSP from Texas
Instruments. The PADK also comes equipped with drivers for all the peripheral elements of the board,
as well as application examples and an Audio Streaming and Wavetable Solution demonstration that
truly showcases the potential of the PADK and its TMS320C6727 digital signal processor.
Outstanding features
The PADK boasts of the following outstanding features:
High-quality BURR-BROWN 24-bit resolution analog-to-digital and digitalto-analog converters
The PADK comprises two ADC and two DAC, each with four channels. The converters are capable of
sampling rates of up to 192 kHz and they are used in multichannel coding, processing, and sound
generation.
S/PDIF coaxial and optical digital audio input and output connectors
Also capable of sampling rates of up to 192 kHz, they are ideal for direct digital professional audio
application development. The digital audio input incorporates a high-resolution sampling rate converter
that allows you to simultaneously operate at different input and output sampling rates, as well as to lock
onto various audio and word clock input sources.
Hi-speed USB port
Perfect for high-speed communications to host computers, it allows you to stream audio in real time, to
download large sound banks, and to handle any other high-bandwidth applications.

Installing the PADK
This section explains how to prepare to install the PADK, how to physically install the PADK, and how
to install the software necessary to use the PADK.
Note
You can download software updates for the PADK. Contact Lyrtech at support@lyrtech.com for
details.
Preparing for installation
Hardware
Because the PADK is a ready-to-use, stand-alone system, there is no need to perform any preliminary
hardware preparation. Jumper settings may influence how you use the PADK, but the initial jumper
positions allow the PADK to start. Refer to the PADK - Technical reference guide for details about
jumper configurations.
Software
To use the PADK in parallel with Code Composer Studio and eXpressDSP, you must first install the
software. Refer to the relevant software documentation for details.
Note
You must install Code Composer Studio 3.3 with the latest product updates before using the PADK. For
the examples available with the PADK software to compile properly, you will also need to install the
latest C672x Chip Support Libraries.

Copying the supplied software to your computer
Before connecting the PADK to your computer, you must first copy the necessary device drivers and
programs on your computer. This software is located on the supplied CD-ROM. Proceed as follows to
install the software on the CD-ROM to your computer.
1. Insert the supplied CD-ROM into the CD-ROM drive of your computer.
2. Access the CD-ROM drive with, for example, Windows Explorer.
3. Double-click Lyrtech_PADK_Software_Tools_SR_{VERSION NUMBER}_{BUILD NUMBER}.exe
file in the root of the CD-ROM.
VERSION NUMBER is the version number of the release and BUILD NUMBER is the date of said
release. An installation wizard starts.
4. Follow the instructions displayed on the screen to proceed.
5. When the installation is finished, click Finish.
The wizard closes.
6. Take a moment to read the POST_INSTALLSHIELD_CONFIGURATION.txt file that opens at the
end of the installation.
It will guide you through important configuration steps.
The installation wizard copies files to the following folders by default in C:\Lyrtech\PADK\

Connecting the PADK
Three avenues are open to you when you connect the PADK to your computer.
• Establishing a connection through the Hi-speed USB port with the supplied USB cable.
• Establishing a connection through the serial interface with a standard RS-232 interface connector
(DB9M/DB9F).
• Establishing a connection through the JTAG interface with a XDS510 or XDS560 emulator for
DSP.
Connecting the PADK through Hi-speed USB
To communicate with the PADK through the USB interface of your computer, connect the USB port of
the PADK board to the one on your computer with the supplied A plug/B plug USB cable.
1. Make sure that the PADK is either disconnected from the power source or the power switch is in the
off position.
2. Connect the A plug of the supplied USB cable to the A receptacle of your computer.
3. Connect the B plug of the supplied USB cable to the B receptacle on the PADK.
Proceed to Installing USB device drivers.
Connecting the PADK through a serial interface
To communicate with the PADK through the RS-232 interface of your computer, connect the RS-232
port of the PADK board to the one on your computer with a standard DB9M/DB9M cable.
Connecting the PADK through the JTAG interface
The PADK is equipped with two JTAG interfaces. To communicate with the PADK through a JTAG
interface, connect the female connector of your emulator pod to the desired male connector of the
PADK board. When you have done so, connect the emulator pod to your computer.
Note
Depending on your type of emulator pod, the connection procedure may be slightly different. Refer the
documentation of your emulator pod for connection details.
