4.2.4 Configuration Tab
The Configuration tab provides access to configure the ADC and the data acquisition system. Click on
any other tab to exit this panel.
The Configuration panel contains the following sub-panels:
– Sample Settings: Provides a switch for manually setting the ADC SPI communications port in
master mode or slave mode. When the Capture Using ADC as Master switch is in the on position,
the ADC SPI is set to master mode and the ADC controls the SPI port data rate using an internally
generated SCLK. When the Capture Using ADC as Master switch is in the off position, the ADC
SPI is set to slave mode, the CapturePlus II system controls the SPI port data rate asynchronous
to MCLK, and the SCLK is asynchronous to MCLK.
– Data Settings: Displays the SPI data format.
– Register Control: Provides buttons for controlling ADC functionality.
Reset Device: Click on the Reset Device button to force a reset of the ADC.
Calibration: Click on the Calibration button to run an ADC calibration sequence. Each time the
button cycles from “Calibrate Off” to “Calibrate On”, a single ADC calibbration sequence will be
initiated.
Note: The calibration function is not supported for all Cirrus Logic ADCs.
Set Dither On / Set Dither Off or Set Awake / Set Sleep: Text on the button indicates the next
available state. Click on the button to set the next state. Example: Click on the button to change
dither setting. When the button text reads Set Dither On the dither function is currently off. Clicking
on the button will turn dither on. Similarly, when the button displays Set Dither Off the dither
function is currently turned on.
Note: For certain ADC evaluation boards this button does not exist. The functionality of this button
changes depending upon the evaluation Board that is connected to the CapturePlus II system.
