Introduction
The Codec Control software is intended to facilitate evaluation of TI audio codecs.
It includes a script interpreter, a block-diagram based graphical user interface, a register inspector and
supplemental features (for example digital filter calculator) depending on codec capabilities.
The AIC3110/AIC3100/AIC3120 EVM works together with the Codec Control software. It connects to a PC
via USB and enumerates as a USB class audio device. Once configured with the Codec Control software,
the EVM acts as a sound card which can play back audio from the PC.

Control Software
This chapter explains how to use the Codec Control software together with a TI audio codec EVM.
2.1
Control Software
The Codec Control software exposes most features of a supported TI audio codec EVM through an
intuitive graphical user interface.
NOTE: Before Windows on the PC can use the TI audio converter EVM as a sound card, the EVM
must be configured (sampling rate, audio routing, internal amplifier settings etc.) with the
Codec Control software.
This will happen automatically once an EVM is detected by the Codec Control software
2.2
Installation
Download the Codec Control software (slac366.exe) from the TI audio codec product folder at
http://www.ti.com and launch the program (double click on slac366.exe).
This file is a self-extracting archive. The default target folder is:
C:\Program Files\Texas Instruments\CodecControl
Click the Unzip button to complete the installation.
The Codec Control software is now available in the target folder. The name of the executable is
CodecControl.exe
To launch the CodecControl software, navigate to the target folder with the Windows Explorer and double
click CodecControl.exe.
2.3
Concepts
The CodecControl software presents a block diagram view of a supported TI audio codec EVM.
The block diagram consists of active objects that can react to user input (for example switches or
amplifiers with variable gain that show a volume control on a mouse click event).
NOTE: Active Objects – Each active object will change color to red if the mouse cursor is above
the object. Clicking the object will trigger its function.
Some active objects are linked to control register(s) of the TI audio codec. The Codec Control software will
update the appropriate register(s) whenever an active object is triggered. If a register that is linked to an
active object is changed via other components (for example the script interpreter or the register inspector),
the active object will change its state accordingly.
The Codec Control software will automatically detect a supported TI audio codec EVM once it is
connected to a USB port of the PC.
If no TI audio codec EVM is connected to the PC, the control software also supports an EVM simulation
mode, where it is possible to retrieve script commands based on user input within the block diagram.

Simulation mode is only available, if no TI audio codec EVM is attached to the PC. Choose File→New
EVM simulation… and select an EVM from the list of supported TI audio codec EVMs.
2.4
EVM Window
Figure 1. EVM Window
At the top of the EVM window is a tool bar with buttons to change between different use cases:
•
Full featured evaluation
•
Playback only
•
Record only
•
Touch Screen Only
Availability of each use case depends on the TI audio codec EVM – some buttons may be grayed out,
indicating that the use case is not available (this does not mean that the use case cannot be implemented
for this TI audio codec).
Each use case has its own initialization script, which will run if a use case is selected by clicking on one of
the use case buttons. The initialization script contains register settings for the TI audio codec to configure
the device for a specific use case.
The toolbar contains a control that determines the zoom factor. Change the zoom by selecting the desired
zoom factor.
To move the block diagram, click on a blank area within the block diagram and drag the diagram with the
mouse.
At the bottom of the EVM window is a status bar that provides information about the state of the
communication between the control software and the TI audio codec EVM. It also shows hints about
elements in the block diagram, for example the I2C™ page and register / bit location of a selected switch.

Audio signal paths (both digital and analog) will change color from black once they are activated via
switches. This feature visualizes all audio paths and immediately highlights if a path is enabled.
2.4.1
Using Active Objects
Moving the mouse pointer over an active object will light up the active object (the color of the object turns
red).
For example, the Class-A/B HP Driver left amplifier active object will turn from its inactive state to its active
state when the mouse pointer enters the amplifier symbol:
Clicking the activated object will trigger its function. In the case of the amplifier active object, the function
is a volume control. Moving the volume control slider changes the volume setting of the amplifier (it is also
possible to change the volume by clicking onto the number within the amplifier symbol and typing the new
gain setting).The Codec Control software updates the appropriate register in the TI audio codec and as a
result the volume on the headphone output will change accordingly.
2.5
Dialogs and Active Objects
The Codec Control software contains several dialog windows that give access to additional features.
Most dialogs are linked to active objects and are opened by clicking on the active object.
A few dialogs are not linked to active objects and are opened using the View menu.
2.5.1
Init Script Dialog
Each use case , , ,
owns a unique initialization script which will automatically run when a
supported TI audio codec is detected or if the user selects another use case.
To show or edit the initialization script, choose View->Init Script… from the main window menu bar.

The register inspector displays the content of the TI audio codec registers. To trigger reading the content
of one page, click the Refresh button.
• The Page edit field selects the page to be displayed.
• The addr column shows the address of the registers within the selected page in decimal notation.
• The description column contains a description for each register. If the register has no function
assigned, it is declared Reserved.
• The data columns show the data of each register (one byte). The first data column uses decimal
notation, the second uses hexadecimal notation. It is possible to change the register value by clicking
into one of the data fields and typing the new value (either decimal or hexadecimal).
• The numbered columns show the register content in binary notation. Read/Write bits are shown solid
black or red; read only bits are gray or dark red. Red numbers represent bits that recently changed. To
change a single writeable bit, click on the bit and it will flip.

This tool displays the combined frequency response, the combined phase response and the individual
frequency response of multiple digital biquad filters (depending on the capabilities of the TI audio
codec).
Solid lines show the frequency response.
The dashed line shows the combined phase response.
Individual frequency response is enabled by checking the right check box in the Enable column.
Zoom is available by holding Ctrl and drawing a zoom window with the left mouse button or
dynamically zooming the gain range with the right mouse button.
To cancel zoom, click the right mouse button while not pressing any key.
Each biquad has its own unique handle with a unique color. To change the frequency and gain of a
biquad, grab and drag its handle.
Each biquad can be configured for parametric EQ, Shelf (Bass and Treble), High Pass, Low Pass,
Phase Shift, Notch.
Some filters (for example High Pass filter) have sub-types that can be selected by the SubType
column.
Due to digital range limitations, the biquads will automatically scale, if the biquad coefficients exceed
the limitations.
The coordinate system will shift accordingly to reflect the resulting attenuation.
Coefficients are automatically sent to the TI audio codec – the filter response can be verified in realtime.
Some filter parameters may lead to unstable filter
CAUTION
If the filter becomes unstable, loud noise may occur.

To add an application, choose Add Application from the context menu (right mouse click within the tree
view).
To change the name of an application, select the application, single click on the application and type the
new name.
Each application owns one or several scripts. The scripts consist of a sequence of commands that
program the TI audio codec (or EVM components). Examples are initialization scripts.
To add a script to an application, choose Add Script from the context menu. Double click on the script to
open a command window. The command window has an open button to choose a script via a file dialog or
alternatively it is also possible to write the script within the command window.
Some TI audio codecs have one or more push buttons that select an application or a script within an
application. Please refer to the EVM user’s guide for further information about how to select applications
and scripts for a specific EVM.
Click Update EVM to program the EEPROM.
Scripts are stored in a compiled binary format on the EEPROM and cannot be read back. A red lock next
to the application name highlights scripts that reside in the EEPROM but can not be viewed in the
command window.
To change the sequence of scripts or applications, drag a script or application to the new position.
2.7
Firmware Update
TI may publish new firmware for TI audio codec EVMs in the future. To program a new firmware to a TI
audio codec EVM, choose File→Update Firmware… and select the new firmware file.
The update process takes a few seconds (there is no progress bar) and will be finished once the update
firmware dialog disappears.
The EVM must be disconnected and reconnected to complete the firmware update process.

get started with the AIC3110/AIC3100/AIC3120 EVM:
Install the CodecControl software (see 2.2).
Launch the CodecControl software.
Plug a headphone into J4.
Connect the EVM to the PC via a mini USB-B to USB-A cable. The CodecControl software will
automatically detect the EVM and run an initialization script, which will configure the
AIC3110/AIC3100/AIC3120 EVM for audio playback through the headphone jack.
Play and/or record music with any Windows application (e.g. Windows Media Player, YouTube,
iTunes…)
EVM Applications
The AIC3110/AIC3100/AIC3120 EVM supports multiple EVM applications that can be stored in the onboard EEPROM.
SW2 cycles through applications. LED D1 indicates, which application is active by blinking N times when
SW1 selects application #N.
SW3 cycles through patches. LED D2 indicates, which patch is applied by blinking N times when SW2
selects patch #N
The first application (if present) is the boot application – the boot application contains a script that is
intended to initialize the AIC3110/AIC3100/AIC3120. It will be skipped by SW1.
The first script of each application contains the application itself. Subsequent scripts of each application
other than the boot application are loaded as patches to the application each time SW2 selects a patch.
It is possible to program complex use cases to the EVM and execute them without having to run the
CodecControl software.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
