To initiate the GUI control, the first step is to ‘Connect’ the GUI. To do this, scroll to the Target section of
the menu and click on Connect (as shown in Figure 12 )
Figure 12. Initiating Connect from the Target Menu
After the Target-Connect operation, the GUI window background changes from white (with grid) to a solid
light-green. All the blocks seen in the GUI window are now active and any updates made on these blocks
updates the corresponding register space. Also, note that the configuration menu options on the right-
hand side (highlighted with blue-box in
Figure 13 ) are now grayed out and cannot be updated. The Target-
Connect operation automatically updates the trim register (0x1B) to factory-trim mode, now the device can
be set to stream audio output with only two additional operations: exit-shutdown and un-mute
The device shut-down mode can be toggled through the Shutdown checkbox (highlighted with a red-box in
Figure 13 ). Uncheck this box to bring the device out of shutdown. Similarly, the mute state of master
volume can be toggled using the Mute checkbox (highlighted with a red-box in Figure 13 ). After un-muting
the master volume, use the volume slider to set the volume to the desired level. The current volume level
is displayed in the menu area on the right-hand side of the GUI window. After completing these basic
operations, the device can now stream audio.
