3.2 EVM Connections
TLV320AIC34EVM-K Setup and Installation
1. Ensure that the TLV320AIC34EVM is installed on the USB-MODEVM Interface board, aligning J13,
J14, J15, J16, J17 with the corresponding connectors on the USB-MODEVM.
2. Verify that the jumpers and switches are in their default conditions.
3. Attach a USB cable from the PC to the USB-MODEVM Interface board. The default configuration will
provide power, control signals, and streaming audio via the USB interface from the PC. On the
USB-MODEVM, LEDs D3-6 should light to indicate the power is being supplied from the USB.
4. For the first connection, the PC should recognize new hardware and begin an initialization process.
The user may be prompted to identify the location of the drivers or allow the PC to automatically
search for them. Allow the automatic detection option.
5. Once the PC confirms that the hardware is operational, D2 on the USB-MODEVM should light to
indicate that the firmware has been loaded and the EVM is ready for use. If the LED is not lighted,
verify that the drivers were installed and trying to unplug and restart at Step 3.
After the TLV320AIC34EVM-K software installation (described in Section 3.2 ) is complete, evaluation and
development using the target TLV320AIC34 can begin.
The TLV320AIC34EVM software can now be launched. The user should see an initial screen that looks
similar to Figure 2 .
