Abstract: PROBLEM TO BE SOLVED: To accomplish touch sensing using master/slave touch controllers.SOLUTION: The master/slave can drive and sense different sets of lines, respectively, of a touch surface. A communication link between the master/slave can be established by transmitting a clock signal between the master/slave, transmitting a command including sequence information to the slave, and initiating a communication sequence from the clock signal and the sequence information. The slave can receive/transmit communications from/to the master during first/second portions of the communication sequence, respectively. Touch sensing operations are synchronized between the master/slave by transmitting a command including phase alignment information from master to slave, and generating slave clock signals based on the clock signal and the phase alignment information, so that sense signal processing by master clock signals are in-phase with sense signal processing by slave clock signals.

Abstract: MASTER/SLAVE CONTROL OF TOUCH SENSING Abstract Touch sensing can be accomplished using master/slave touch controllers that transmit drive 5 signals to a touch surface and process sense signals including superpositions resulting from master/slave drive signals. The master/slave can drive and sense different sets of lines, respectively, of the touch surface. A communication link between master/slave can be established by transmitting a clock signal between master/slave, transmitting a command including sequence information to the slave, and initiating a communication sequence from the 10 clock signal and sequence information. The slave can receive/transmit communications from/to the master during first/second portions of the communication sequence, respectively. Touch sensing operations can be synchronized between master/slave by transmitting a command including phase alignment information from master to slave, and generating slave clock signals based on the clock signal and the phase alignment information, such that sense signal processing 15 by master clock signals are in-phase with sense signal processing by slave clock signals.

Abstract: Berührungserfassung (touch sensing) kann unter Verwendung von Master/Slave-Berührungssteuereinheiten erreicht werden, die Ansteuerungssignale (drive signals) an eine Berührungsoberfläche übertragen, und Erfassungssignale (sense signals) einschließlich Überlagerungen verarbeiten, welche aus Master/Slave-Ansteuerungssignalen resultieren. Der Master/Slave kann unterschiedliche Sätze von Leitungen der Berührungsoberfläche ansteuern bzw. erfassen. Eine Kommunikationsverbindung zwischen Master/Slave kann durch Übertragen eines Taktsignals (clock signal) zwischen Master/Slave, Übertragen eines Befehls einschließlich Sequenzinformation an den Slave, und Initiieren einer Kommunikationssequenz von dem Taktsignal und der Sequenzinformation hergestellt werden. Der Slave kann Kommunikationen vom/zum Master während ersten/zweiten Teilen der Kommunikationssequenz empfangen/übertragen. Berührungserfassungsoperationen können zwischen Master/Slave synchronisiert werden, durch Übertragen eines Befehls einschließlich Phasenausrichtungsinformation (phase alignment information) vom Master zum Slave, und Erzeugen von Slave-Taktsignalen basierend auf dem Taktsignal und der Phasenausrichtungsinformation, so dass Erfassungssignalverarbeitung durch Master-Taktsignale in Phase mit der Erfassungssignalverarbeitung durch die Slave-Taktsignale sind.
