Using the GUI
3 Using the GUI
This section describes the details of using the TAS57xx ControlConsole Graphical User Interface (GUI)
software tool to interface with the TAS5721 or TAS5723 device. The software is available for download at
the EVM product page on www.TI.com. The GUI's main function provides an easy way to manipulate the
device register space for attaining the required signal processing flow. Clicking the question mark in the
upper right-hand corner of the GUI opens an introductory help file explaining each tab of the GUI. Read
the help file for a complete understanding of the full functionality of the GUI.
3.1 ControlConsole Quick start
3.1.1 Launching ControlConsole
Before opening ControlConsole, power the TAS5721-TAS5723EVM and Input-USB Board3, and connect
the USB cord from the Input-USB Board3 to the computer. When starting ControlConsole an initialization
script runs, turning on the device. If power to the EVM is lost, close ControlConsole and restart it, running
the script again. Alternatively, enter the register values manually using the Direct I2C Access tab.
Select the correct target when opening ControlConsole with the following steps:
• Navigate to the Texas Instruments Inc title in the start program menu
• Open the ControlConsole folder
• Select the correct target, opening ControlConsole
Double check the names of the tabs at the top of the GUI; the device name should be either TSA5721 or
TAS5723 (depending on the IC used). A green circle appears in the lower left-hand corner of the GUI
indicating that communication is established with the board.
3.1.2 Process Flow Tab
The Process Flow tab options with their descriptions are shown in Table 1. Select the correct sample rate
from the drop-down box in the lower left-hand corner of the GUI. While the TAS5721 and TAS5723 auto-
detect the sample rate, the GUI has no way of detecting what the sample rate is.
Make sure the Mode setting in the lower right-hand corner of the GUI is correct. The TAS5721 and
TAS5723 operate in 2.0 or 2.1 modes, depending on the desired speaker configuration. There is not a
quick PBTL set-up option. Section 4 explains the PBTL set up.
When finished setting-up, make sure the device is out of shutdown. In the lower right-hand corner of the
Process Flow tab, the Shutdown button reads Exit if it is out of shutdown, and Enter if it is in shutdown.
Click to toggle between the two.
At this point, the device should stream audio. Use the Direct I2C Access tab for writing directly to the
TAS572X registers. Use the TAS5723 Registers tab for viewing the current register values, as well as for
modifications of individual bits.
3.1.3 Summary of Steps
1. Power the TAS5721-TAS5723EVM and Input-USB Board3
2. Connect the Input-USB Board3 to the computer with a USB cable
3. Open ControlConsole GUI with the correct target:
(a) Verify that the GUI displays the correct device name
(b) Verify that a green dot is displayed in the lower left-hand corner of the screen. If the dot is red,
verify that the EVM is powered correctly and that the USB cable is connected from the computer
running ControlConsole to the EVM.
4. Go to the TAS572X Process Flow tab
5. Set the correct sample rate in the lower left-hand corner
6. Select the correct speaker configuration in the lower right-hand corner under Mode
7. Make sure that the device is out of Shutdown
The EVM should now stream audio.
