Title:
CAPACITANCE DETECTION METHOD AND APPARATUS BASED ON CAPACITIVE TOUCH CONTROL CHIP
Document Type and Number:
WIPO Patent Application WO/2017/143711
Kind Code:
A1
Abstract:
A capacitance detection method and apparatus based on a capacitive touch control chip. The method comprises: setting configuration information about a channel to be detected, wherein the configuration information contains information about a start sequence of various channels to be detected and pre-configuration information (201); according to the pre-configuration information, pre-configuring the channels to be detected before detection (202); according to the information about the start sequence of the channels to be detected, starting a first channel to be detected, and detecting a capacitance value generated by the touch of a user in a currently started channel to be detected (203); and when the detection of the capacitance value of the currently started channel to be detected is completed, starting the next channel to be detected according to the information about the start sequence, and continuing to detect a capacitance value of the next channel to be detected until the detection of capacitance values of all the channels to be detected is completed (204). The method and apparatus may improve the flexibility of setting of a channel to be detected, improve the detection efficiency and reduce the detection costs.
