Software Quick-Start Guide
To initialize the TAS5711EVM in its default state of 2.1, AD mode operation, perform the following steps.
1. Open the TAS570X GDE by clicking Start → All Programs → Texas Instruments Inc → TAS570x GDE
→ TAS570X GDE.
2. Select the TAS5711 tab.
3. If the mode is 2.0 or PBTL, select accordingly on the mode menu in the properties window.
4. If the modulation scheme is not AD, select that also. In 2.1 mode, the SE channels are always AD.
5. Jumper JP1 must be left open when used in SE or BTL mode. Jumper JP1 must be IN for PBTL mode.
See Section 4 for information on how to manipulate the more advanced features of the TAS570x GDE,
such as the I2C Memory Tool, the Biquad GUI, and the DRC GUI.
Using the EVM Software
Initial Steps
Select the appropriate tab; in this case, select the TAS5711_10 tab. It has two subwindows. One shows
the Process Flow window. From the Process Flow window, each of the signal processing function tools
can be selected by clicking on it. The Biquad GUI (labeled as BQ1, BQ2, etc.) and the DRC GUI (labeled
as DRC1, DRC2, etc.) can be opened by using the right mouse button. This window also shows Input
select, Mode select, Channel, and Master Volume. All functions are arranged visually in the order that they
are in the device.
The other subwindow, Properties, has the properties that a user can view or update by selecting from the
available options. The properties available change with the device selected. From the main window, the
user must set three properties before connecting to the EVM.
Set the Current Device field to TAS5711, adjust the sampling rate (in the Current Rate Field) and enable
or disable the autobank switch function (in the Coef Banking Field). The TAS5711 automatically detects
sample rates; however, setting the sample rate in the GUI allows optimal synchronization with the device.
Connect the GUI to the EVM
Once the properties window selections have been made, go to the menu Target → Connect.
This sends the initialization commands to the device. Master volume is in mute by default. Select the
master volume function. Type the required volume in the properties window. At this time, audio, if
connected properly, plays through the device. If no audio is heard, ensure that the All channel shutdown is
unchecked. When the Connect command is issued, if an error appears indicating a USB problem, check
the connections, and press the USB RESET button on the controller board. Then disconnect and
re-connect the EVM from the Target menu.
I2C Memory Tool
This tool can be opened from GDE (Tools → I2C Memory Tool) or independent of GDE from Start →
Program → Texas Instruments Inc → Memory Tool.
Select I2C as show in Figure 9 .
