OPERATING METHOD OF PULSE WIDTH MODULATION DRIVER FOR CONTROLLING PULSE WIDTH MODULATION UNIT OF MICROCONTROLLER MODULE BASED ON AUTOSAR

摘要

PURPOSE: An operating method of pulse width modulation driver for controlling PWM(Pulse Width Modulation) unit of micro controller module base on AUTOSAR(Automotive Open System Architecture) is provide to divide information of PWM information and information such as register address and setting value necessary for controlling PWM unit with realization of API(Application Program Interface) functions, thereby improving reusability and scalability of software. CONSTITUTION: A PWM(Pulse-Width Modulation) driver(310) generates a PWM signal by controlling PWM unit of a micro controller. A PWM property container(320) stores waveform properties of PWM signal by the PWM driver. A PWM configuration container(330) stores setting information of the PWM unit. Based on information recorded in the PWM property container, the PWM driver grasps the waveform properties of the PWM signal. Based on information recorded in the PWM configuration container, the PWM driver performs setting of the PWM unit.
