FDC2214: FDC2214 detection and interference。

Part Number: FDC2214

 I use Fdc2214 in the use of detection ，can not detect the completion of the interrupt signal, How do I set the interrupt to detect the signal?


2: In FDC214 I/O  measure a only half of the sine wave, when the capacitance value increases , the amplitude of the sine wave is reduced, and even no sine signal

,if this will affect the accuracy of the measurement, ?

    Hello,

    Please check the STATUS and ERROR_CONFIG registers for more information on interrupt.

    The amplitude of the half sine wave should be kept around 1V to 1.8V. It seems the change in capacitance may be very large. You can probably reduce the sensor size to reduce the change in capacitance.
