Abstract
A processing method for implementing high resolution output of a capacitive touch pad on a low-end single-chip microcomputer. The low-end single-chip microcomputer device comprises a master control single-chip microcomputer unit (MCU), a self-checking capacitance sensing module and a capacitive touch pad. The master control single-chip microcomputer module controls the self-checking capacitance sensing module to obtain source data acquired by the self-checking capacitance sensing module from the capacitive touch pad, then the source data are subjected to touch position computing by the master control single-chip microcomputer to obtain an original coordinate data of a touch point, and then a coordinate position can be obtained through an optimizing computation processing.
