Detailed Description

A motor class for one channel of the DRV8847.

Objects of this class can be used to apply PWM to a given DC motor.

Constructor & Destructor Documentation

__init__()

def motor_04.Motor_04.__init__	(		self,
		pyb.Timer	PWM_tim,
		pyb.Pin	IN1_pin,
		pyb.Pin	IN2_pin,
		int	timChannel1,
		int	timChannel2
	)

Initializes and returns an object associated with a DC Motor.

Objects of this class should not be instantiated directly. Instead create a DRV8847 object and use that to create Motor objects using the method DRV8847.motor() Must specify correct timer channel to work with IN2_pin

Parameters

PWM_tim	Passes in a timer object for generating the PWM signal.
IN1_pin	The first input pin for this motor.
IN2_pin	The second input pin for this motor.
timChannel1	The first timer channel for the motor, attached to IN1_pin
timChannel2	The second timer channel for the motor, attached to IN2_pin

Member Function Documentation

set_duty()

def motor_04.Motor_04.set_duty	(		self,
			duty
	)

Set this PWM duty cycle for the motor channel.

This method sets the duty cycle to be sent to the motor to the given level. Positive values cause effort in one direction, negative values in the opposite direction.

Parameters

duty	A signed number holding the duty cycle of the PWN signal sent to the motor
