2.2 Getting Started
Evaluation can start right out of the box:
1. Install jumpers for TLV320AIC3262EVM-U (see Section 7 for default jumper settings)
2. Download and install the TLV320AIC3262EVM-U Control Software from the EVM product folder. The
password for installation is "CC".
3. Connect the TLV320AIC3262EVM to an available USB port. LED lights D1 and D2 should illuminate
once the EVM is detected by PC. Also in the Windows device manager, the EVM should be recognized
as “USB Composite Device”.
Figure 2. USB Connection
4. Connect stereo headphones at the headphone output (J4)

6. Play audio through any media playback tool on your PC. Make sure the playback setup on the PC is
through ‘”USB-miniEVM”.
To adjust playback volume, open “Sounds and Audio Devices Properties” in the control panel, and click
the Volume button of the Sound playback section of the Audio tab. Ensure that “USB-miniEVM” is selected
as the default playback and recording devices.
The following section explains the software installation procedure which allows programming of the audio
device.
3 AIC3262 Control Software
The following sections describe the operation and installation of the AIC3262 control software.
3.1 AIC3262EVM CS Setup
To install the TLV320AIC3262 EVM-U software:
1. Download the latest version of the AIC3262EVM-U Control Software (CS) located in the
TLV320AIC3262 Product Folder.
2. Open the self-extracting installation file, and extract to a known folder.
3. In that folder, install the Software by double-clicking the “CC.exe” and follow the directions. The
installation password is “CC”.
4. Connect TLV320AIC3262EVM-U to PC through USB cable and open up TLV320AIC3262 Control
Software. The software will then pop up a window called select EVM to prompt the user to choose the
correct EVM name

3.2 Using the AIC3262EVM-U CS
The following sections describe the AIC3262EVM-U CS usage.
3.2.1 Main Panel Window
The Main Panel window, shown in Figure 4, provides easy access to all the features of the AIC3262 CS.
Figure 4. Main Panel Window
The main panel provides a high-level block diagram of the AIC3262. On the main panel, shown in
Figure 4, users can configure the analog input and output routings by simply clicking on the switches. The
analog setup, digital setup, audio inputs, audio outputs, DRC, AGC, SAR and headset detection provide
additional control of many other features of the AIC3262. These categories are intended for advanced
users and can be accessed by clicking “View” on the main panel. One can also click on the colored blocks
on the main panel to gain access to these categories. Left ADC and Right ADC blocks provide detailed
settings for recording path. Left DAC and Right DAC blocks provide detailed settings for playback path.
Yellow block in the middle provides settings for digital interface, which includes Audio Serial Interface
configuration, clock settings, etc.
Clicking “Refresh” button on the top will read back the current state of the AIC3262 register settings and
reflect it to the user interface. “EVM status” on the bottom part of the main panel reflects the hardware
connection of the EVM. “USB Fs” indicates the current sample rate of the EVM board.

3.2.2 Typical Configuration
AIC3262 Control Software provides example scripts to typical playback and record application. These
typical record and playback configurations can be accessed by choosing “Example Configuration…” under
View. Once the typical configuration is selected, click “ProgramCodec” to download the script into EVM.

3.2.3 Command-Line Interface Panel
Figure 6. TLV320AIC3262 Control Software Command-Line Window
The command-line interface provides a means to communicate with the TLV320AIC3262 using a simple
scripting language (described in the Section 8). 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.
All controls update their status with respect to the register contents in the following conditions:
• A panel is open
• The “Run” button in the command-line interface is pressed
• The “Refresh” button on the main panel window is pressed

One feature in the command-line interface is the “Decode” function of the script. Clicking the “Decode”
button on the command-line interface will decode the script line by line. This decode feature provides an
easy means to understand the meaning of the script without referring to the register map. The decode
content can be cleared by clicking “ClearDecode”.
Figure 7. Decode Window
Another feature in the command-line interface is the “Record” function. By checking the “Record” box, one
can record the current value of the register that is being modified. The recorded register values along with
their page numbers are displayed in the command buffer. The recorded register values can also be
decoded by clicking the “Decode” tab on the command-line interface window. The content of the
command buffer can be cleared by clicking “Clear” button.

3.2.4 Register Inspector Table
Figure 8. Register Inspector Window
The contents of TLV320AIC3262 register map can be accessed through the Register inspector table. 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.
While using the register inspect table, user should first specify the page number. Once the page is
specified, user can inspect or change the register value by either entering the hex value of the register or
changing the corresponding bits for that register.
