Kit Operation
The software should automatically find the TLV320DAC32EVM, and a screen similar to the one in
Figure 2 should appear.
Figure 2. Digital Audio Data/DAC Tab
The diagram shown in Figure 1 displays 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 TLV320DAC32EVM is a double-wide modular EVM, it is installed with connections to both EVM
positions, which connects the TLV320DAC32 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 TLV320DAC32EVM. To view all the
functions and configuration options available on the USB-MODEVM board, see the USB-MODEVM
Interface Board schematic in Appendix B .
Figure 2 illustrates the indicators and controls near the top of the screen, and a large tabbed interface
below. This section covers the controls above this tabbed section.
