In one embodiment, channel scan logic carries out many of the functions that a processor would normally undertake, including generating timing sequences and obtaining result data; comparing scan result data against a threshold value (e.g., in an auto-scan mode); generating row count; selecting one or more scanning frequency bands; power management control; and performing an auto-scan routine in a low power mode.

摘要： Touch sensing can be accomplished using master/slave touch controllers that transmit drive 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 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 by master clock signals are in-phase with sense signal processing by slave clock signals.

摘要： Embodiments of the present invention are directed to a microcontroller which includes a Register Load Assist engine. The microcontroller can include no or minimal non-volatile memory which stores boot data. Thus, most of the boot data can be stored at a non-volatile memory external to the microcontroller. An external circuit can read the externally positioned non-volatile memory and send compressed boot data to the microcontroller. The boot data can be originally stored in compressed form in the external non-volatile memory or it can be compressed by the external circuit. The boot data can be received by the microcontroller and saved in an intermediate location in the microcontroller's internal volatile memory. The RLA engine can then uncompress the boot data and store various portions of it in their final destinations (such as, for example, in respective registers).

摘要： Centralized processing of touch information obtained by multiple touch sensing controllers connected to a touch sensing surface is provided. Each touch controller can obtain touch information of sense signals from different sense lines of the touch sensing surface and can store the touch information in a corresponding memory of the controller. The touch information of one or more of the touch sensing controllers can be transmitted as results data to a processor that processes all of the touch information. In some cases, prior to transfer of the results data, a determination of the validity of a sense channel can be made, and invalid channels can be excluded from the transfer.

摘要： A system and method for autonomously scanning a sensor panel device, is disclosed. A sensor panel processor can be disabled after a first predetermined amount of time has elapsed without the sensor panel device sensing any events. One or more system clocks can also be disabled to conserve power. While the processor and one or more system clocks are disabled, the sensor panel device can periodically autonomously scan the sensor panel for touch activity. If one or more results from the autonomous scans exceed a threshold, the sensor panel device re-enables the processor and one or more clocks to actively scan the sensor panel. If the threshold is not exceeded, then the sensor panel device continues to periodically autonomously scan the sensor panel without intervention from the processor. The sensor panel device can periodically perform calibration functions to account for any drift that may be present in the system.
