The system further comprising a processing device configured to determine the stylus location on the capacitive sense array based on the transmit signal and to synchronize the stylus to the capacitive sense array. A system further comprises a demodulation block to extract additional data that is modulated into the transmit signal by the stylus. The demodulation block is configured to extract the additional data by amplitude shift keying. The additional data comprises at least one of an applied force value of the stylus tip, a button status data, a battery status data, or a stylus acceleration data.

摘要： A parallel pipelining method of operation of a touch sense controller for processing data into a touch map is disclosed. A current full scan of response signals to at least one excitation of a touch sense array is received using a first thread of a processing device. The current full scan of response signals is processed using a second thread of the processing device to render a touch map corresponding to the touch sense array. A next full scan of response signals is received using the first thread. Receiving the next full scan and processing the current full scan are performed substantially simultaneously.

摘要： A method for improving noise immunity of capacitive sensing circuit associated with a touch sense array is disclosed. The capacitive sensing circuit receives a response signal from a touch sense array. The capacitive sensing circuit measures a noise component of the response signal. When a level of noise of the noise component within a passband of the capacitive sensing circuit is greater than a threshold, the capacitive sensing circuit changes at least one parameter of capacitive sensing circuit to move the passband substantially outside the frequency spectrum of the noise component.
