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.
2
C interface is the default interface
used by the EVM.
Figure 4. Interface Selection Window
If the I
2
C 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 I
2
C 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 .
