Input device for touch sensitive devices

摘要

A method for receiving data from an input device to a computing device through a touch interface. The method includes detecting an input device, synchronizing with the input device by receiving a position signal and activating an input device scan of the touch interface, receiving a data signal from the input device through at least one of a sense line or a drive line of the touch interface, and scanning the touch interface for a touch input by applying a stimulation signal to the at least one drive line and analyzing the at least one sense line.

主权项

1. An electronic device configured to receive input from an input device comprising:
a touch sensor panel including a plurality of sensing lines and a plurality of driving lines; and a touch controller in communication with the touch sensor panel and configured to perform a plurality of scans to detect an input signal corresponding to an object touching or in proximity to the touch sensor panel, the touch controller including a drive controller and a sensing circuit; wherein the touch controller is configured to interleave a first scan of the plurality of scans and a second scan of the plurality of scans while receiving a data signal from the input device; wherein during the first scan the drive controller is configured to drive at least one of the plurality of driving lines and the sensing circuit is configured to sense the plurality of sensing lines; and wherein during the second scan the sensing circuit is configured to sense at least one of the plurality of sensing lines and at least one of the plurality of driving lines.
