CodecControl Software
The CodecControl software is intended to facilitate user evaluation of TI audio codecs. It includes a script
interpreter, an interactive device block diagram-based GUI, a register inspector, and supplemental
features depending on the specific codec capabilities.

features depending on the specific codec capabilities.
This chapter explains how to use the CodecControl software together with a TI audio codec EVM.
2.1
Control Software
The CodecControl software exposes most of the features of a supported TI audio codec EVM through an
intuitive graphical user interface.
intuitive graphical user interface.
NOTE:
Before a PC running Windows can use the TI audio converter EVM as a sound card, the
EVM must be properly configured (sampling rate, audio routing, internal amplifier settings,
etc.) with the CodecControl software. This configuration occurs automatically once an EVM is
detected by the CodecControl software.

Installation
Download the CodecControl software from the
audio codec product folder and launch the
program. The file is a self-extracting archive that is downloaded in a compressed format.
The default target folder is:
C:\Program Files\Texas Instruments\CodecControl
Click the Unzip button to complete the installation. The CodecControl software is now available in the
target folder. The name of the executable is CodecControl.exe.

Concepts
The CodecControl software presents a block diagram view of a supported TI audio codec EVM, such as
that shown in
that shown in
.
The block diagram consists of active objects that respond to user input (for example, switches or
amplifiers with variable gain that show a volume control when a user clicks on the component with a
mouse).

mouse).
NOTE:
Active Objects: Each active object changes color to
red
if the cursor is placed over the
object. Clicking the object triggers its function.
Some active objects are linked to control register(s) of the particular TI audio codec. The CodecControl
software updates the appropriate register(s) whenever an active object is triggered. If a register that is
linked to an active object is changed through other components (for example, the script interpreter or the
register inspector), the active object changes its state accordingly.
