A Processing Method for Implementing High Resolution Outputs of a Capacitive Touch Pad on a Low-Performance Single-Chip Microcomputer The present invention discloses a processing method for implementing high resolution output of a capacitive touch pad. on a low performance single chip microcomputer. The low performance single chip microcomputer device comprises a master control single chip (mcu) microcomputer unit, a self-checking capacitance detection module and a capacitive touch pad. the master control single chip microcomputer module controls the self check capacitance detection module to obtain source data acquired by the self check capacitance detection module from the capacitive touch pad, then the source data is subjected to touch position computation by the single master control chip microcomputer to obtain the coordinate data of an initial touch point, and then a coordinate position can be obtained by optimizing computation processing. The present invention also provides a capacitive touch control device utilizing the above processing method and a remote controller containing the capacitive touch control device described above. In this method, low-performance single-chip microcomputer and capacitive touch pad electronic devices are incorporated to take full advantage of the calculation and processing capabilities of the low-performance single-chip microcomputer to improve the processing efficiency of high-resolution capacitive touch pad outputs can be achieved on the low-performance single-chip microcomputer.
