Detailed Description

A motor driver class for the DRV8847 driver from TI.

Objects of this class can be used to configure the DRV8847 motor driver and to create one or more objects of the Motor class which can be used to perform motor control.

Refer to the DRV8847 datasheet here: https://www.ti.com/lit/ds/symlink/drv8847.pdf

Constructor & Destructor Documentation

__init__()

def driver.DRV8847.__init__	(		self,
			timNum
	)

Initializes and returns a driver object.

Parameters

timNum

the timer number for the pins being used

Member Function Documentation

enable()

def driver.DRV8847.enable

(

self

)

Brings the driver out of sleep mode.

To bring the driver out of sleep mode without causing a fault, the fault pin is disabled for 50 microseconds while it turns on

faultCB()

def driver.DRV8847.faultCB	(		self,
			IRQ_src
	)

Callback function to run on fault condition.

Parameters

IRQ_src

The source of the interrupt request.

motor()

def driver.DRV8847.motor	(		self,
			pinIn1,
			pinIn2,
			chA,
			chB
	)

Creates a DC motor object connected to the driver.

Parameters

pinIn1	The first pin associated with the motor
pinIn2	The second pin associated with the motor
chA	The first channel associated with the motor
chB	The second channel associated with the motor

Returns

An object of class Motor
