Preface SLAU448 – June 2012 Introduction This user's guide describes the features, software and typical configurations of TLV320AIC3262 stick evaluation module (EVM). This small form factor evaluation module is a programmable USB audio device that features the TLV320AIC3262 audio codec with miniDSP. Figure 1. TLV320AIC3262 Stick EVM Front View Figure 2.
Chapter 1 SLAU448 – June 2012 TLV320AIC3262 EVM Software The TLV320AIC3262 EVM graphical user interface (GUI) can be downloaded from TLV320AIC3262 online product folder: http://www.ti.com/. A detailed description of how to use the GUI is introduced in SLAU386A.
Chapter 2 SLAU448 – June 2012 Use TLV320AIC3262 Stick EVM for Typical Playback and Recording Configuration 1. Connect the TLV320AIC3262 stick EVM to your PC universal serial bus (USB) port. The light-emitting diode (LED) light D1 will turn on. If the LED light is not on, follow Appendix A to flash electrically erasable programmable read-only memory (EEPROM) image. 2. Open the Codec Control GUI. This software can be downloaded from the TLV320AIC3262 product folder.

Appendix A SLAU448 – June 2012 TLV320AIC3262 Stick EVM EEPROM Image Programming Guide 1. Install the TotalPhaseUSB-v2.10 driver using TotalPhaseUSB-v2.10.exe. This driver installation file is located at: \\vette02\dg_audio\USERS\Austin\software. 2. Open the Aardvark™ GUI by double-clicking on Aardvark GUI.exe. Aardvark GUI is located at: \\vette02\dg_audio\USERS\Austin\software\aardvark-gui-windows-v3.53. 3. Setup the hardware.
Appendix A www.ti.com • Click Load and select the TUSB3200firmware.xml file, then click Execute. The TUSB3200firmware.xml file is located at \\vette02\dg_audio\USERS\Austin\software • If the I2C communication is okay, the status line turns green and shows Running.
Appendix A • • 14 www.ti.com The status line turns red when the download completes. Disconnect the TLV320AIC3262 stick EVM from the Aardvark GUI and connect the TLV320AIC3262 stick EVM directly to a PC. Open the TLV320AIC3254 Control Software. The sample rate of the stick EVM should be 48 kHz.
