6.3 USB-MODEVM Interface Board
Kit Operation
The software should automatically find the TLV320AIC32EVM, and a screen similar to the one in Figure 2
should appear.
Figure 2. Default Software Screen
The simple diagram shown in Figure 1 shows only the basic features of the USB-MODEVM Interface
board. The board is built around a TAS1020B streaming audio USB controller with an 8051-based core.
The board features two positions for modular EVMs, or one double-wide serial modular EVM may be
installed.
Since the TLV320AIC32EVM is a double-wide modular EVM, it is installed with connections to both EVM
positions, which connects the TLV320AIC32 digital control interface to the I
2
C port realized using the
TAS1020B, as well as the TAS1020B digital audio interface.
In the factory configuration, the board is ready to use with the TLV320AIC32EVM. To view all the functions
and configuration options available on the USB-MODEVM board, see the USB-MODEVM Interface Board
schematic in Appendix B.
