Note

compatible with all boards that support analogWrite()

Constructor & Destructor Documentation

JMotorDriverAvrL293()

JMotorDriverAvrL293::JMotorDriverAvrL293 ( byte  _en, byte  _i1, byte  _i2, bool  _breakOn = true, bool  breakWhenDisabled = false, bool  _reverse = false  )

inline

constructor, sets pins

Parameters

_en	enable(speed) pin on driver
_i1	input pin 1 (direction)
_i2	input pin 2 (direction)
_breakOn	= true: if true (default), add extra resistance to motor when set to 0 power (by shorting motor terminals)
breakWhenDisabled	= false: if false (default) turn off break when disabled, if true, keep electrically breaking
_reverse	(bool) default=false, reverse direction of driver

Member Function Documentation

getEnable()

bool JMotorDriverAvrL293::getEnable ( )

inlinevirtual

get the enable state of the driver

Return values

(bool)

true if enabled, false if disabled

Reimplemented from JMotorDriver.

getMaxRange()

float JMotorDriverAvrL293::getMaxRange ( )

inlinevirtual

high end of the range

Note

usually 1.0

Return values

(float)

maxRange

Reimplemented from JMotorDriver.

getMinRange()

float JMotorDriverAvrL293::getMinRange ( )

inlinevirtual

low end of the range

Note

usually -1.0, if 0, that indicates a motor controller with no reverse function

Return values

(float)

minRange

Reimplemented from JMotorDriver.

set()

bool JMotorDriverAvrL293::set ( float  val )

inlinevirtual

set motor power

Note

val should be between getMinRange and getMaxRange, but constrained internally

Parameters

val	(float) val

Return values

(bool)

false if at end of power range, true otherwise

Reimplemented from JMotorDriver.

setEnable()

bool JMotorDriverAvrL293::setEnable ( bool  _enable )

inlinevirtual

use to enable or disable a motor, and sets up pin states

Note

setEnable(true) must be called before a motor driver will activate

Parameters

_enable

(bool) true=enable, false=disable

Return values

(bool)

true if state changed, false if state already set

Reimplemented from JMotorDriver.
