Abstract: A method for detecting PWM wave comprises: starting counting when a PWM wave is detected; interrupting the counting when a value of the counting reaches a predetermined value; determining whether electric level of the PWM wave during the interruption is high electric level or low electric level; clearing the value of the counting, starting a next counting and interrupting the next counting when a value of the next counting reaches the predetermined value; determining whether the electric level of the PWM wave during the interruption of the next counting is high electric level or low electric level; clearing the value of the counting and repeating the counting and the determining until one period of the PWM wave; and calculating a duty ratio of the PWM wave based on a number of high electric level and a number of low electric level determined within one period of the PWM wave.
