Abstract
Disclosed are sensing systems and methods that eliminate CPU intervention or interrupts when performing sensor scans of a touch interface, supports low power sensing operation without requiring periodic wake up of the CPU, and is scalable to multi-channel or multi-chip sensor configuration to support large touch screens or a high number of sensors. Sensor scanning is configured and controlled by an autonomous engine and comparison is completed by wake-up detection logic, operable without CPU interaction.
