EVM Description and Basics 2.1.1 www.ti.com USB-MODEVM Interface Board The simple diagram of Figure 1 shows only the basic features of the USB-MODEVM Interface board. Because the TLV320DAC3203EVM is a double-wide modular EVM, it is installed with connections to both EVM positions, connecting the TLV320DAC3203 digital control interface to the I2C port realized using the TAS1020B, as well as the TAS1020B digital-audio interface. In the factory configuration, the board is ready for use with the USB-MODEVM.
EVM Description and Basics www.ti.com 2.2 2.2.1 Default Configuration and Connections USB-MODEVM Table 1 provides a list of the SW2 settings on the USB-MODEVM. For use with the TLV320DAC3203EVM, SW-2 positions 1, 3, 4, 5, 6, and 7 must be set to ON, whereas SW-2.2 and SW2.8 must be set to OFF. If the TLV320DAC3203EVM is used with an external audio interface, SW2.4 and SW2.5 also must be set to OFF and such interface must be connected as explained in Section 2.4 Table 1.
EVM Description and Basics 2.2.2 www.ti.com TLV320DAC3203 Jumper Locations Table 2 provides a list of jumpers found on the EVM and their factory default conditions. Table 2. List of Jumpers and Switches Jumper Default Position Jumper Description W1 1-2 Sets IOVDD to 3.3 V (default) or 1.8 V. W2 2-3 Sets DIGMIC_PWR to 3.3 V (default) or 1.8 V. W3 Removed Connects GPIO2 to RESET line. W4 Installed Provides a means to measure LDOin/HPVDD current.
EVM Description and Basics www.ti.com 2.5 Power Connections The TLV320DAC3203EVM is powered independently when being used in stand-alone operation or by the USB-MODEVM when it is plugged onto the motherboard. 2.5.1 Stand-Alone Operation When used as a stand-alone EVM, power is applied to P23/J23 directly, making sure to reference the supplies to the appropriate grounds on that connector.

Extract the software to a known folder. 4.
TLV320DAC3203EVM-K Setup and Installation www.ti.com The TLV320DAC3203EVM-K software can now be launched. An initial screen similar to Figure 3 is displayed. Figure 3.
DAC3203 Control Software 4 www.ti.com DAC3203 Control Software The DAC3203 Control Software (CS) is an intuitive, easy-to-use, powerful tool for learning, evaluating, and controlling the TLV320DAC3203. The following sections describe the operation of this software. NOTE: For configuration of the codec, the TLV320DAC3203 block diagram located in the TLV320DAC3203 data sheet is a good reference for determining the signal routing. 4.
DAC3203 Control Software www.ti.com 4.1.1 Typical Configurations The Typical Configurations panel quickly increases familiarity with the TLV320DAC3203. This panel has controls relevant to the selected configuration and shows the script for that configuration loaded in a tab. Each script includes a brief description of the selected configuration, as shown in Figure 4. Figure 4. Playback Script Tab 4.1.2 Features The Features category allows evaluation of various features of the TLV320DAC3203.
DAC3203 Control Software 4.1.3 www.ti.com Control Categories The Digital Settings, Analog Settings, and Signal Processing categories provide control of many registers and other features of the TLV320DAC3203 . These categories are intended for the advanced user. Hovering the mouse cursor on top of a control displays a tip strip containing page, register, and bit information.
DAC3203 Control Software www.ti.com 4.2 Status Flags Panel The TLV320DAC3203 status flags are monitored in the Status Flags panel (Figure 7), located below the Panel Selection Tree . Pressing the POLL button continuously reads all the registers relevant to each flag and updates those flags accordingly. The rate at which the registers are read is modified by changing the value in the Polling Interval numeric control.
DAC3203 Control Software 4.3 www.ti.com Register Tables Panel The contents of configuration and coefficient pages of the TLV320DAC3203 are accessed through the Register Tables panel (Figure 8). The Page Number control changes to the page displayed in the register table. The register table contains page information such as the register name, reset value, current value, and a bitmap of the current value. Export the contents of the selected page into a spreadsheet by clicking the Dump to Spreadsheet button.

www.ti.com Appendix G Writing Scripts G.1 Writing Scripts A script is a text file containing data sent to the serial control buses. Each line in a script file is one command. No provision is made for extending lines beyond one line, except for the > command. A line is terminated by a carriage return. The first character of a line is the command.
Writing Scripts www.ti.com For example, writing the values 0xAA 0x55 to an I2C device with a slave address of 0x30, starting at a register address of 0x03, the input is: #example script I i2cfast w 30 03 AA 55 r 30 03 02 This script begins with a comment, specifies that a fast I2C bus is used, then writes 0xAA 0x55 to the I2C slave device at address 0x30, writing the values into registers 0x03 and 0x04. The script then reads back two bytes from the same device starting at register address 0x03.
