摘要：A system for controlling an electronic device, including an accessory coupled tothe device having a control interface for receiving at least one input and a tone

generator, the accessory configured to, in response to an input, generate a

corresponding control tone using the tone generator, and send the control tone and acalibration sequence to the device. The device is operable to receive the calibrationsequence and control tone. The device includes a zero-crossing detector operable todetermine at least one of the start or ending of each of the calibration sequence and thecontrol tone and having a circuit operable to determine the periods of the calibrationsequence and the control tone based on the zero-crossing detector output.
