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. The bottom part of the GUI main panel shows the connection status of the EVM as well as the
current sampling rate.
Go to Appendix A if the sampling rate of the EVM should be changed.
3. Headphone playback configuration (default script works for 48 kHz or 44.1 kHz Fs)
• Connect the headset to TLV320AIC3262 stick EVM connector HP_OUT
• Go to View → Example Configurations… → HP Playback, and then click the Program Codec
button.
• Play the music file through any windows media player. Make sure the sound playback default
device is set as USB Mini Multi Channel EVM.

4. SPK playback configuration (default script works for 48 kHz or 44.1 kHz Fs)
• Use the speaker cable provided to connect stereo speakers to the SPK_OUT connector of the
TLV320AIC3262 stick EVM.
• Go to View → Example Configurations…→ Class D Playback, and then click the Program Codec
button.
• Play the music file through any windows media player. Make sure the sound playback default
device is set as USB Mini Multi Channel EVM (same as HP playback).
5. Microphone recording configuration (default script works for 48 kHz or 44.1 kHz Fs)
• Connect the stereo single-ended microphone to the MIC_IN connector of the TLV320AIC3262 stick
EVM.

• Go to View → Example Configurations… → ADC Record IN2L-R, and then click the Program
Codec button.
• Turn on MICBIAS by writing b0_p1_r51 = 0x07 (w 30 33 07) in the command line interface.
• Record through any windows recording software (for example, Goldwave). Make sure the sound
recording default device is set as USB Mini Multi Channel EVM.
6. Receiver playback configuration (default script works for 48 kHz or 44.1 kHz Fs)
• Connect the mono receiver to the REC_OUT connector of the TLV320AIC3262 stick EVM.
• Go to View → Example Configurations… → Receiver Playback, and then click the Program Codec
button.

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.
• Build the I2C®(SDA, SCL, IOVDD, GND) connection between the Aardvark GUI and the
TLV320AIC3262 stick EVM.

• Connect the Aardvark GUI to a PC through USB cable. Now the Aardvark GUI will be recognized
as the Total Phase Aardvark I2C/SPI Host Adaptor under the windows device manager.
4. Program the TUSB3200 firmware (\\vette02\dg_audio\USERS\Austin\software\TUSB3200 image)
• Open the Aardvark GUI and click Configure Aardvark Adaptor
• Highlight the Aardvark port and select Batch Mode, then click okay.
