Detailed Description

Prototype of class for ustepper servo.

Definition at line 44 of file uStepperServo.h.

Constructor & Destructor Documentation

uStepperServo()

uStepperServo::uStepperServo

(

)

Constructor for servo class.

This constructor is used to instantiate a new servo class, and should be used for each servo the user wishes to connect to the uStepper.

Definition at line 103 of file uStepperServo.cpp.

Member Function Documentation

attach()

uint8_t uStepperServo::attach

(

int

pinArg

)

Attaches the servo motor to a specific pin.

This method is used to attach the instantiated servo motor object to a specific pin connected to the servo input terminal

Parameters

[in]

pinArg

Pin connected to servo input terminal

Returns

0 on failure

Definition at line 118 of file uStepperServo.cpp.

detach()

void uStepperServo::detach

(

)

Detaches the servo motor from the uStepper.

This method detaches the servo motor from the uStepper

Definition at line 130 of file uStepperServo.cpp.

refresh()

void uStepperServo::refresh ( )

static

Updates servo output pins.

This method updates the pulses on the servo output pins. This method must be called at least once every 50 ms, to ensure correct movement of the Servo motors!

Definition at line 152 of file uStepperServo.cpp.

setMaximumPulse()

void uStepperServo::setMaximumPulse

(

uint16_t

t

)

Sets the maximum pulse.

This method sets the maximum pulse length given to the servo motor. This pulse length defines the fully open angle.

Parameters

[in]

t

Maximum pulse width in microseconds

Definition at line 113 of file uStepperServo.cpp.

setMinimumPulse()

void uStepperServo::setMinimumPulse

(

uint16_t

t

)

Sets the minimum pulse.

This method sets the minimum pulse length given to the servo motor. This pulse length defines the fully closed angle.

Parameters

[in]

t

Minimum pulse width in microseconds

Definition at line 108 of file uStepperServo.cpp.

write()

void uStepperServo::write

(

int

angleArg

)

Specify angle of servo motor.

This method sets an angle setpoint for the servo motor

Parameters

[in]

angleArg

The angle argument

Definition at line 141 of file uStepperServo.cpp.

Member Data Documentation

angle

uint8_t uStepperServo::angle

private

Current angle in degrees

Definition at line 50 of file uStepperServo.h.

first

uStepperServo * uStepperServo::first

staticprivate

Pointer to hold address of first servo in chain

Definition at line 63 of file uStepperServo.h.

max16

uint8_t uStepperServo::max16

private

Maximum pulse width in timer0 ticks (default = 150 = 2.4ms)

Definition at line 56 of file uStepperServo.h.

min16

uint8_t uStepperServo::min16

private

Minimum pulse width in timer0 ticks (default = 92 = 1.472ms)

Definition at line 54 of file uStepperServo.h.

next

class uStepperServo* uStepperServo::next

private

Pointer to hold address of next servo in chain, if multiple servos are connected

Definition at line 60 of file uStepperServo.h.

pin

uint8_t uStepperServo::pin

private

Digital output pin connected to servo input terminal

Definition at line 48 of file uStepperServo.h.

pulse

uint16_t uStepperServo::pulse

private

Pulse width in timer0 ticks (1 tick = 16us)

Definition at line 52 of file uStepperServo.h.
