TLV320AIC3104EVM Software

The following section discusses the details and operation of the EVM software.

Note:

For configuration of the codec, the TLV320AIC3104 block diagram located in the

TLV320AIC3104 data sheet is a good reference to help determine the signal routing.

The software that is installed provides operation for several devices. An initial window should appear that

looks like Figure 3. For operation with the TLV320AIC3104EVM, the user should select AIC3104 from the

pulldown menu and click Accept. The software will take a few seconds to configure the software for

operation before proceeding. A progress bar should appear and show the status of the configuration.

Figure 3. Device Selection Window

When the program first starts up, a small window (Figure 4) appears that gives two choices for the control

interface: IC or SPI. Click on the interface that will be used by the EVM, as selected by the jumper settings

detailed in Table 2. The setting of J10 should agree with the selection. 2C interface is the default interface

used by the EVM.

Figure 4. Interface Selection Window

If the I2C interface is selected, a second window then appears which allows for selecting the address of

the TLV320AIC3104. This window (see Figure 5) has two sliders for setting the state of A0 and A1. To

allow proper communication with the EVM, these should match the settings of J11 and J12 (Table 2).

When A0 and A1 are adjusted, the correct device address will be shown. Note that the actual I2C address

shown and the address for the software may be different. This is done for programming reasons and the

correct address should be used for system development .
