    get_sensorcp API in CY8CKIT-040

      Hello I'm new in this forum


      I'm trying to use the get_sensorcp(); API but  I don't know how can I look for the result. I looked in the datasheet but I don't see


      any example, please help.

          Welcome in the forum.


          Excerpt from datasheet:


          uint32 CapSense_GetSensorCp(uint32 sensor)
          This API returns the Cp (parasitic capacitance) of sensor in pF (pico farads).
          The supported range is 5-100 pF. The precision of API is +/-10%.
          Note This API can be used to measure a capacitance of the external capacitors. In this case the parasitic capacitance should be subtracted from the total result.
          uint32 sensor: Sensor number. The Capsense.h file contains defines for the sensor numbers. See the Sensor Constants section for details.
          Return Value:
          uint32: This API returns Sensor parasitic capacitance (Cp) of the sensor indicated as argument. The unit of sensor Cp value is pico-farads.
          Side Effects:
          Sensor scan should be complete before using this API.


          What more do you need? An uint32 is returned.
