2 Introduction
This specific evaluation module (EVM) is a programmable USB audio device that features the
TLV320AIC3268 Audio Codec with miniDSP.
2.1 Electrostatic Discharge Warning
Many of the components on the EVM are susceptible to damage by electrostatic discharge (ESD). Users
are advised to observe proper ESD handling precautions when unpacking and handling the EVM,
including the use of a grounded wrist strap at an approved ESD workstation.
CAUTION
Failure to observe ESD handling procedures can result in damage to EVM
components.

www.ti.com Introduction
2.2 Unpacking the EVM
On opening the TLV320AIC3268EVM-U package, ensure that the following item is included:
• One TLV320AIC3268EVM-U board using one TLV320AIC3268 (Figure 1 and Figure 2)
If either of the board or the TLV320AIC3268 device is missing, contact the Texas Instruments Product
Information Center to inquire about a replacement.

Getting Started www.ti.com
3 Getting Started
1. Request and download the PPC2 software located in the EVM product folder on the web.
2. Connect the EVM to USB port, LED lights LED1 and LED2 should illuminate once the EVM is detected
by Windows®PC. Also, in the Windows Device Manager, the EVM should be recognized as a USB
composite device, a USB audio device and an HID-compliant device.
3. Connect headphones to jack J7, labeled HP OUT.
4. Open PPC2 and in the Command Buffer Interface select Open.
5. Download the most up-to-date scripts from the product folder. Navigate to that folder and select script
1.1 and click Execute.
6. Play audio through any media tool. Make sure that the playback (and recording) device is USB-
AudioEVM in the Windows control panel.
• To adjust playback volume, open Sound in control panel, select the USB-AudioEVM device and
click Properties.
• Similarly, the other example configurations can be tried and sound can be recorded using the
microphone available on the board.
7. Install jumpers on the EVM as per the requirements to make the right signal connections.
4 PurePath Console 2 Software
4.1 Installation
1. Request and download the PPC2 software located in the TLV320AIC3268 product folder.
2. Open the self-extracting installation file, and extract contents to a known folder.
3. Install the software by double clicking the setup executable and follow the directions.
4. Connect the EVM to a USB port using a micro-USB cable and open PurePath Console 2. If prompted,
select the appropriate EVM name.

4.2 Graphical User Interface (GUI)
4.2.1 Main panel window
The main panel, shown in Figure 3, provides direct access to the I2C settings of the AIC3268. On the
main panel, users can configure the registers through the single byte write and read or through the
Command Buffer Interface. The analog setup, digital setup, audio inputs, audio outputs, DRC, AGC, SAR
and headset detection can be configured through this interface.
The EVM status, which reflects the hardware connection of the EVM, is shown on the bottom left of the
main panel.
Figure 3. Main Panel
4.2.2 Typical Configuration
In the product folder there are example scripts for typical playback and record applications. These
configurations are used through the Command Buffer Interface.
4.2.3 I2C Logger
The Command Buffer Interface communicates with the TLV320AIC3268 using a simple scripting language
(described in Section 9). The TAS1020B USB controller handles all communication between the PC and
the codec. A script is loaded into the command buffer, either by loading a script file using the Open button
or by pasting text from the clipboard. Click Run to execute the command buffer.
To record the I2C communication between the PC and the device, there is an I2C Logger in the bottom
right of the GUI. The I2C Logger records all register writes sent to the codec when the Logging box is
checked. The recorded register values along with their page numbers are displayed in the I2C Logger
Window. Pressing the Clear button clears the content of the logger.

4.2.4 Register Inspector
Figure 4. Register Inspector Window
The contents of the TLV320AIC3268 register map can be accessed through the Registers tab in PPC2.
The Page number control selects the page to be displayed in the register table. The register table contains
information such as register name, current register value and the bit field of the current register value.
Specify the page number when using the register inspector table. Once the page is specified, the register
value can then be inspected or changed by either entering the hex value of the register or changing the
corresponding bits for that register.
