Abstract
A state machine for controlling a sensor including a chip package coupled with photo-emitters and photo-detectors mounted in a device, and with a host processor, including an emitter driver, a detector driver, a signal processor for generating signals representing amounts of light detected by the detectors, and a scan controller for controlling the emitter and detector drivers to activate an automated sequence of emitter-detector pairs, the scan controller including registers for storing parameters designating emitter-detector pairs that are to be activated during the automated sequence, and for storing the signals generated by the signal processor for the emitter-detector pair activations, and at least one input/output pin for receiving parameters from the host processor to be loaded into the registers, and for outputting the stored signals in the registers to the host processor, for the host processor to identify therefrom location coordinates of an object near or touching the device.
