5.3 Settings Page
There is only one control setting on the Settings page ( Figure 15 ). The control can be used to force a
hardware reset to the ADS1219. Clicking the Reset button twice forces the reset pin low with the first click,
and then returns the pin high with the second button click.

5.4 Chart Page
There is only one Chart page option available ( Figure 16 ) and that is the Time Domain Analysis plot. For
any data to be displayed in a continuous mode of operation requires that the Conversion Mode in the
ADS1219 register setting be set to Continuous .
5.4.1 Time Domain Analysis
The plot begins when the START button in pressed. When the chart begins to display data, the START
button changes to STOP. Data are displayed on the chart until the STOP button is pressed. There are two
ways the data can be displayed. One option is to display by voltage and the second option displays by the
number of codes. The voltage option is the default, and the voltage value displayed depends on the gain
applied in the register setting and the reference voltage being used. The default reference voltage
displayed is the internal reference voltage of the ADS1219. If another reference source is used, update
the reference voltage box to accurately display the voltage value determined at the ADC input.
