6. Evaluation Mode Operation
6.1.2 DAC
Configuration area
The DAC configuration area allows configuration of the target’s output audio. This must
be done before using any of S1V30xxx’s applications which output audio.
Figure 8 Evaluation Audio configuration area
The DAC Config button is used to configure S1V30xxx’s audio hardware with the selected
parameters from the DAC Configuration area. Clicking this button causes an
ISC_AUDIO_CONFIG_REQ message to be sent to the target.
The following sequence of messages should be displayed to signal successful configuration
of the audio.
‘ISC_AUDIO_CONFIG_REQ: sending’
‘ISC_AUDIO_CONFIG_RESP: success’
If this is not the case please refer to the trouble-shooting guide.
6.1.2.1 Routing
The Routing Drop-box is used to configure the basic routing of audio data
output from S1V30xxx. Four Options are provided:
•
Application to DAC:
Audio Data from Applications are routed to the
integrated DAC on S1V30xxx.
•

Note that in some cases the routing selection may be incompatible with the
routing of the ADC and an error will be reported in the System Message
Window.
