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.
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
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
CodecControl.exe
To launch the CodecControl software, navigate to the target folder with the Windows Explorer and double
click CodecControl.exe.
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).
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.

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.
