Abstract
In one embodiment, a controller includes a processor and a memory, the memory storing logic. The logic is configured to perform, when executed by the processor, operations including detecting, in response to driving a plurality of electrodes of a touch sensor with a first drive signal having a first polarity, a first sense signal. The first sense signal has a second polarity, the second polarity being an inverse of the first polarity. The logic is further configured to perform operations including driving, in response to detecting the first sense signal, the plurality of electrodes with a second drive signal having the second polarity.
