Abstract

A power-saving scanning method for a touch device is provided. Firstly, a controller is used to shorten a normal scanning time of a timer into a power-saving scanning time. Then, a counter is used to count the oscillating waveform within the power-saving scanning time to access a power-saving oscillating number. Afterward, the controller is used to convert the power-saving oscillating number into an (L-n)-digit M-bit count value, shift the (L-n)-digit M-bit count value toward the higher digit by n digits, and pad the lower digits with n zeros to form another L-digit M-bit count value so as to generate an M-bit oscillating number simulation value for the determination of touch operation.
