The motor node is designed to receive a desired speed and a desired steering angle from the driver node. These values will be used to adjust the RC Car's motor speed and servo motor angle to align with those requested values.
There are four public functions that are provided in the motor node.
- This function is used by the periodic callback to initialize the required peripherals used to control the motor speed as well as the servo motor angle.
- This function is used by the periodic callback to set the motor speed and the servo motor angle. This public function will invoke two private functions, motors__speed_handler() which handles the motor speed of the car, and motors__steering_handler() which handles the steering angle of the car.
- void motors__set_speed_and_steering_values(dbc_MOTOR_VALUES_s *motor_values)
- This function is used by the CAN Bus Message Handler to set the desired speed and steering angle. When the CAN Bus Message Handler module receives a CAN package, it will decode the motor values and call this function. This function is also used by the MIA handler as well to stop the RC Car if it doesn't receive any CAN messages from the driver node ten times in a 10Hz periodic callback.
- dbc_MOTOR_VALUES_TO_DRIVER_s motors__get_motor_values(void)
- This function is used by the CAN Bus Message Handler to transmit the current speed of the car.
