AIC3254 Control Software

4 AIC3254 Control Software

The AIC3254 Control Software (CS) is an intuitive, easy-to-use, powerful tool to learn, evaluate, and

control the TLV320AIC3254. This tool was specifically designed to make learning the TLV320AIC3254

software easy. The following sections describe the operation of this software.

NOTE: For configuration of the codec, the TLV320AIC3254 block diagram located in the

TLV320AIC3254 data sheet is a good reference to help determine the signal routing.

4.1 Main Panel Window

The Main Panel window, shown in Figure 2, provides easy access to all the features of the AIC3254 CS.

The Firmware Name and Version boxes provide information about the firmware loaded into the EVM's

EEPROM.

The USB-MODEVM Interface drop-down menu allows the user to select which communication protocol

the TAS1020B USB Controller uses to communicate with the TLV320AIC3254 or to toggle the TAS1020B

GPIO pins. The TLV320AIC3254 supports I

C Standard, I

C Fast, and 8-bit register SPI. The USB-

MODEVM Interface selection is global to all panels, including the Command-Line Interface. To

communicate to the TLV320AIC3254 using SPI, SW1 must be switched towards SPI and W14 must be

set to 1-2 on the TLV320AIC3254EVM.

The Panel Selection Tree provides access to typical configurations, features, and other panels that allow

the user to control the TLV320AIC3254. The tree is divided into several categories which contain items

that pop up panels. A panel can be opened by double-clicking any item inside a category in the Panel

Selection Tree.

Below the Panel Selection Tree are three buttons that pop up the following:

• Status Flags - Allows the user to monitor the TLV320AIC3254 status flags.

• Register Tables - A tool to monitor register pages.

• Command-Line Interface - A tool to execute/generate scripts and monitor register activity.

The USB LED indicates if the EVM kit is recognized by the software and the ACTIVITY LED illuminates

every time a command request is sent.

The dialog box at the bottom of the Main Panel provides feedback of the current status of the software.
