2.3 Using the Application Softwarewww.ti.com Using the Application Software

This section discusses the various controls available in the application software using screenshots anddescribing the possible control functions for each tab.

For evaluation of PCM1691 audio performance with EVM default conditions settings, no applicationsoftware operation and no switch, jumper, or header setting changing on the EVM are required. Thisapplication software is used to control the register contents of the PCM1691 to various values necessaryfor a given application.

The PCM1691 operating mode, including the audio interface format and sampling mode, can be setthrough the serial control port by this PCM1691 control application software in either I2C or SPI controlmode.

The application software is not required for PCM1691 hardware control mode. Switch SW102 on the EVMis used for limited functions in hardware control mode.



2.3.1 Audio Interface and Sampling Mode Control (SPI Mode)Using the Application Software www.ti.com

Figure 2-2 shows the audio interface and sampling mode control tab for SPI mode.

Figure 2-2. Audio Interface and Sampling Mode Control Tab—SPI Mode Recognized

This screen has the following features:• This tab is the initial window that appears, and indicates that the USB connection with the PC and the

EVM is properly recognized; it also shows that SPI serial control is the interface mode.• PCM1691 audio interface mode and oversampling mode can be set in this window.

Additionally, four important controls are visible in Figure 2-2.

ReconnectThis button performs a reconnect operation between the PC and the EVM. When the interface mode(either I2C or SPI) or the I2C slave address changes, pushing this button is required. For systemrecovery after releasing the USB cable or turning off the EVM power supply, pushing this button is alsorequired.

ExitThis button closes and exits the application software.

MRST (Mode Register Reset)The MRST button resets all PCM1691 register settings and the application software.

SRST (System Reset)The SRST button resynchronizes the PCM1691. The register setting is not cleared.



2.3.2 Audio Interface and Sampling Mode Control (I2C Mode)www.ti.com Using the Application Software

Figure 2-3 illustrates the audio interface and sampling mode control tab for I2C mode.

Figure 2-3. Audio Interface and Sampling Mode Control Tab—I2C Mode Recognized

As with SPI mode (see Section 2.3.1), this initial display screen confirms proper a USB connection withthe PC and the EVM, as well as indicates that I2C serial control mode is properly recognized.

Note that when I2C mode is selected, there is an additional control that becomes active:

Address SettingThis field sets the I2C slave address for the software. This address must concur with the addressregistered on the EVM. In other words, the I2C address of the EVM and the software must be thesame.



2.3.3 USB Connection and EVM Not RecognizedUsing the Application Software www.ti.com

Figure 2-4 displays the audio interface and sampling mode control tab as it appears when the USBconnection with the PC and the EVM and/or serial control mode is not properly recognized. Note the redNo EVM button.

Figure 2-4. Audio Interface and Sampling Mode Control Tab—USB Connection and EVM Not Recognized

TroubleshootingIf there is no change after pushing Reconnect button, the following items should be checked:

q Are the power supplies correctly distributed for the EVM?q Is the EVM properly connected to the PC?q Is the USB port on the PC activated?q Is the Virtual COM port driver software (that is, the USB driver software) correctly installed on the PC?q Is the selection of SPI/I2C control mode coincident between the application software and the EVM

setting for the PCM1691?q If I2C mode is selected, is the I2C slave address the same for the application software and the EVM

setting on the PCM1691?If you have thoroughly reviewed these procedures and there continues to be no change with the NoEVM indication, contact the Texas Instruments product support center nearest you for assistance.



2.3.4 Operation Mode Controlwww.ti.com Using the Application Software

The operation mode control tab is shown in Figure 2-5.

Figure 2-5. Operation Mode Control Tab

This tab has the following features:• Power-Save Mode• De-emphasis• Digital filter roll-off• Polarity (phase) between input and output

As illustrated in Figure 2-5, these features can be controlled by channel pairs or by all channels.



2.3.5 Digital Attenuation and Soft Mute ControlUsing the Application Software www.ti.com

Figure 2-6 shows the digital attenuation and soft mute control tab.

Figure 2-6. Digital Attenuation and Soft Mute Control Tab

Digital attenuation can be controlled for each channel by either changing the slider location or directlyentering a target number in 0.5- or 1-dB increments.• Soft mute on or off using digital attenuation can be also controlled for each channel; operation of digital

attenuation control is ignored while the mute is on.• Choose between Fine or Wide digital attenuation mode (fine control extends to 63 dB with 0.5-dB

steps; wide control covers a 100-dB range with 1.0-dB steps),



2.3.6 Zero Flag Control and Monitorwww.ti.com Using the Application Software

Figure 2-7 shows the zero flag control and monitor tab.

Figure 2-7. Zero Flag Control and Monitor Tab

Both the function and the signal polarity of the zero flag pins (PCM1691 pins 1 and 2) can be controlled.The status of zero input detection is updated by channel when a Read command is performed; a zero flagindication is cleared by pushing the Clear button.



2.3.7 Analog Mute Function ControlUsing the Application Software www.ti.com

Figure 2-8 illustrates the analog mute function control tab.

Figure 2-8. Analog Mute Function Control Tab

This window enables the user to select a source event for the analog mute control function of thePCM1691. Four source events can be selected independent of each other:• SCKI lost• Asynchronous clocks• ZERO1 or ZERO2 detection• DAC disable command



2.3.8 Register Setting History, Register Direct Accesswww.ti.com Using the Application Software

The Register Setting History and Register Direct Access area of the software interface is shown inFigure 2-9.

Figure 2-9. Register Setting History, Register Direct Access Area

Register Setting HistoryThe register setting history is shown as Register Address, Register Data in hexadecimal. This historycan be downloaded as a comma-separated value (.csv) file by pressing the Save button. An uploadfunction is also available from the File menu. The Clear button clears this history.

Register Direct AccessBoth read and write functions (read and write any data to or from any address) are available.

Open Script from File MenuThis menu uploads a previously saved register setting snapshot from a stored .csv file.

Save Register Snapshot from File MenuThis menu downloads a register setting snapshot in .csv file format. The saved register settingsnapshot can then be uploaded by the File/Open Script command.



2.3.9 Register Contents ViewUsing the Application Software www.ti.com

Figure 2-10 illustrates a view of the register contents. This option shows all registers of the PCM1691 in aregister map format.

Figure 2-10. Register Contents View

The Register View window has three options (available in the application software):

Open Register View WindowSelect Tools → Register Map. This window indicates latest entire register settings of PCM1691.

Register View Window Color IndicatorsGreen shaded cells (as shown in Figure 2-10) indicate a register value of '1'. White shaded cellsindicate a register value of '0'.

Register View Window OperationAfter updating a register setting for the PCM1691 through the application software, the update isreflected in this register view.

Typical Performance Data www.ti.com

This section illustrates baseline PCM1691 performance on the DEM-DAI1691 with the defaultconfiguration. These data include typical performance versus sampling rate and system clock, and FFTresults for full-scale, –60 dB, –120 dB, and bipolar zero at 48 kHz/512 fS. As a result of a performancelimitation of the second-order active LPF and buffer for 2-VRMS out followed by the PCM1691 output, thereading performance is shown with 0.5-dB to 1.0-dB degradation in dynamic range, signal-to-noise ration(SNR), and channel separation.

Figure 3-1 shows typical PCM1691 performance versus the sampling rate and system clock.
