Output Data Format
This section allows you to select the output format of the data
conversions and to enable the parity. When several analog
inputs are enabled, the Data + Status option should be selected
under Data Only.
Registers HEX
This window displays the values to be written to the AD7190/
AD7192 registers. When features such as the analog input chan-
nel, gain, and mode of operation are changed, the values in the
Register HEX section are updated automatically. You can write
directly to the Registers HEX section, altering the contents of
any register. When the values in this section are altered, the
other sections of the ADC Setup window are updated to reflect
the changes.
CONFIGURATION ASSIST TOOL
The AD7190/AD7192 evaluation software can be used as a
configuration assist tool, even when an AD7190/AD7192
evaluation board is not connected. When the AD7190/AD7192
evaluation board software is open, click the ADC Setup button.
The message shown in Figure 9 appears. Click the Ignore
button. The ADC Setup window opens. You can use the ADC
Setup window to determine the values to be written to the
AD7190/AD7192 on-chip registers for different configurations.
When you change the configuration (for example, the gain or
channel), the values in the Register HEX section are updated
automatically. You can manually alter the values in the
Registers HEX section as well. When the values in this section
are altered, the other sections of the ADC Setup window are
updated so that you can easily see the impact of the register
changes.
