Using the EVM Software
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. Select the master volume function.
Type the required volume in the properties window. For TAS5708/10, type –12 dB. The difference is due
to the power stage gain in both devices. At this time, audio, if connected properly, plays through the
device. Check the All channel shutdown button. It should be un-checked. When the Connect command is
issued, if an error appears that indicates 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.
