Question: Can I force a sensor’s baseline to reset using host control with a CapSense® Express™ (CY8C201xx) device?
Yes, you can do this by writing a "1" to bit 7 of the CS_Filtering register, which reinitializes the baseline. The bit automatically clears after the baseline is reset. You should not reset the baseline when a finger is on the button.
