1. A method for indication of an interference level by a touch sensor controller coupled to a touch sensor panel, the touch sensor controller comprising an audio or visual output device, the method comprising:
outputting, by the touch sensor controller, drive signals to the touch sensor panel;
receiving, by the touch sensor controller, response signals output from the touch sensor panel;
determining, by the touch sensor controller, an interference level using the signals received from the touch sensor panel, comprising analyzing signal levels of the response signals received from the touch sensor panel; and
generating, by the audio or visual output device of the touch sensor controller, an audio or visual output that indicates the interference level, wherein the touch sensor controller is connectable to a host computing device that receives touch information from the touch sensor controller and controls a display as a function of the received touch information, wherein the audio or visual output device of the touch sensor controller is separate from the host computing device and the display.
