Hello,

The Cs formula in the CapSense_GetSensorCapacitance API of the CapSense datasheet seems to be a Single IDAC formula.

Is this API determined by this formula regardless of Single or Dual IDAC?

Hi YoIs_1298666​,

CapSense_GetSensorCapacitance uses it's own settings as mentioned in the component datasheet irrespective of the settings you do for the sensors in the component. Compensation IDAC is disabled when performing absolute Cp measurement and therefore only single IDAC formula is used for Cp calculation.
