Note:
Before Windows on the PC can use the TLV320AIC3111 EVM as a sound card, the
TLV320AIC3111 on the EVM must be configured (sampling rate, audio routing, internal
amplifier settings etc.) with the TLV320AIC3111 control software.
Download the TLV320AIC3111 control software (
) from the TLV320AIC3111 product folder at
and launch the program (
This file is a self-extracting archive. The default target folder is:
C:\Program Files\Texas Instruments\AIC3111
Click the Unzip button to complete the installation.
The TLV320AIC3111 control software is now available in the target folder. The name of the executable is
CodecControl.exe
To launch the TLV320AIC3111 control software, navigate to the target folder with the Windows Explorer
and double click CodecControl.exe.
The TLV320AIC3111 control software presents a block diagram view of the TLV320AIC3111 (or select
modules within the TLV320AIC3111).
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:
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 TLV320AIC3111 in a two way fashion. If an
EVM is connected, the 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 control software will automatically detect a TLV320AIC3111 EVM once it is connected to a USB port
of the PC.
If no TLV320AIC3111 EVM is connected to the PC, the control software changes to a simulation mode,
where it is possible to retrieve script commands based on user input within the block diagram.
