    Question: Can I force a sensor’s baseline to reset using the host with a CapSense® Express CY8CMBR3xxx family of devices?

     

    Answer:

    A reset input to a CY8CMBR3xxx CapSense® controller (software reset, hardware reset, or power cycle reset) can reset the baseline. Sending a SLEEP command through the I2C interface and waking up the device can also reset the baseline without resetting the controller.
