Abstract
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.
