Abstract
A touch-sensing system comprises an active stylus including a probe electrode and associated sensory logic. The sensory logic is configured to receive a synchronization pulse sequence via the probe electrode between consecutive touch-sensing frames of a capacitive touch screen, to use the synchronization pulse sequence to establish a timing scheme shared between the active stylus and the capacitive touch screen, to receive an excitation pulse via the probe electrode within a given touch-sensing frame, and to use the excitation pulse to maintain the shared timing scheme.
