3.1 Connect the GUI to the EVM
Open the GUI by clicking Start → All Programs → Texas Instruments Inc → TAS57x → TAS57x GUI.
Connect the MC57xxPSIA board (attached to the TAS5717EVM) to your PC with a USB cable. In the
Properties window, select 1-band or 2-band DRC and select Stereo or Woofer. Stereo is selected for BTL
and Woofer is selected for PBTL Mode.
The master volume is muted by default. Select the master volume block. Type the required volume in the
Properties window.
Connect the GUI to the EVM hardware by clicking Target → Connect. This sends the initialization
commands to the device. Un-check Shutdown and Mute. At this time, if connected properly, audio plays
through the device. 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 from the Target menu.
