Abstract
An apparatus having a stylus scribing surface and a sensor configured to communicate with a stylus via a wireless communication path regarding a location of the stylus with respect to that stylus scribing surface also has a control circuit that operably couples to that sensor. The control circuit is configured to automatically test that wireless communication path for interference. In response to detecting an undue level of interference the control circuit instructs the stylus to modify the wireless communication path (for example, by switching to a different carrier frequency).
