Detailed Description

This class implements a motor driver for an ME 405 kit.

Constructor & Destructor Documentation

__init__()

def motor_driver.MotorDriver.__init__	(		self,
		str	en_pin,
		str	in1pin,
		str	in2pin,
		int	timer,
		int	ch1,
		int	ch2
	)

Creates a motor driver and configures the appropriate pins, timers, and timer channels.

Parameters

en_pin	String containing the pin label of the enable pin (e.g. 'A10' for pin A10)
in1pin	String containing the pin label of the first PWM channel
in2pin	String containing the pin label of the second PWM channel
timer	Number of the timer to configure, given as integer (e.g. 5 for TIM5)
ch1	The channel number of the first PWM channel, given as integer (e.g. 1 for TIMx CH1)
ch2	The channel number of the second PWM channel, given as integer

Member Function Documentation

set_duty_cycle()

def motor_driver.MotorDriver.set_duty_cycle	(		self,
		int	level
	)

Drives the motor at a given duty cycle.

Parameters

level

PWM duty cycle to drive the motor at. Given as integer from -100 to 100 (inclusive). The sign affects the direction the motor will be driven.
