1. A method of transferring data between a first device and a second device, the method comprising:
generating, using an output circuit, an analog signal based on a data signal for an application associated with the first device and the second device; and
transmitting the data signal over an interface between a processor of the first device and a processor of the second device, the transmitting of the data signal over the interface comprising capacitively coupling the analog signal through a capacitor formed by at least one sensor electrode, of a touchscreen, of the first device and a conductor of the second device.
