The application expects the following Device descriptor values:
If the application started successfully the user should see the window as in Fig 7.5. This
is the main application window through which the user can interact with the Device on
ColdFire.
44.1kHz or 8 kHz sample rate can be selected before starting the sample. In order to start
audio loop-back click the “Start” button. The application begins PCM samples delivery
from the sound source to the USB Device on ColdFire and receiving processed data from
the bus. The sample rate selection becomes unavailable during the loop-back operation.
The Device delivered samples will be shown in PCM Loop-back Scope (fig 7.6). Volume
control changes will affect the volume level of the data from the Device.
