Title:
MODULATION SIGNAL PROCESSING APPARATUS AND METHOD, AND MICRO CONTROL UNIT AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/185263
Kind Code:
A1
Abstract:
The present application provides a modulation signal processing apparatus and method, and a micro control unit and an electronic device. The modulation signal processing apparatus is applied to a micro control unit, and comprises: a first signal processing module, which is connected to an analog-to-digital converter of the micro control unit and is used for receiving a completion mark output by the analog-to-digital converter, collecting a conversion value output by the analog-to-digital converter, and generating corresponding bit data according to a total number of sampling times and a preset half-cycle value; and/or a second signal processing module, which is connected to a PWM output timer of the micro control unit and is used for converting the bit data into a modulation data packet that complies with a Qi protocol, and respectively calculating a reload value of the PWM output timer and a corresponding frequency modulation parameter according to the modulation data packet and a preset modulation configuration parameter, such that the PWM output timer outputs a corresponding pulse width modulation signal. The modulation signal processing apparatus in the present application is integrated as a whole, can directly operate a timer, and has high compatibility, high precision and ease of implementation.
