Abstract
This disclosure generally provides a processing system that includes a first controller coupled with a second controller via a first communication link. The first controller is configured to transmit display data to the second controller via the first communication link. The second controller is configured to drive, using the display data, one or more coupled display electrodes for performing display updating. The second controller is further configured to operate one or more coupled sensor electrodes to acquire capacitive sensing data, and to transmit the capacitive sensing data to the first controller via the first communication link.
