The potentiometer on the BOOSTXL-ULPSENSE is connected as a voltage divider. The example uses COMPA and the reference DAC to implement a SAR-ADC, which compared to the on-board ADC, significantly reduces the current consumption.
The potentiometer example is tested with the potentiometer set to the middle position. The Sensor controller will wake up with a rate of 25 Hz, and if a change is detected, it will wake up and notify the System CPU. The system CPU will blink a LED when the value changes.
