The present invention discloses 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. The present invention also provides a capacitive touch control device using the above processing method, and a remote controller containing the above-described capacitive touch control device. In this method, the electronic devices of the low-end single-chip microcomputer and the capacitive touch pad are incorporated to fully take advantages of calculation and processing capabilities of the low-end single-chip microcomputer so as to improve data processing efficiency, so that the high resolution outputs of the capacitive touch pad can be achieved on the low-end single-chip microcomputer. |
