Abstract

Systems having a capacitive touch sensing system with transmit and receive electrodes positioned to have mutual capacitances at node intersections that deviate when a node is touched; a processor; and a machine readable storage medium with instructions to: assign complete code words to transmit electrodes; identify a subset of transmit electrodes based on a prior touch position estimate; generate a transmit signal for the transmit electrodes; receive a first portion of a receive signal for receive electrodes indicative of capacitances; decode the first portion of the receive signal of receive electrodes using the first portions of the code words; and compute touch position estimates for the subset of transmit electrodes based on the decoded first portions of the receive signals.
