Member Function Documentation

void angle_position ( float  angle )

Turn the motor to a specific degree angle with a resolution of 0.5 degrees.

Parameters:
angledesired angle (0-(max_positon/2))

Definition at line 96 of file Stepper_Motor_X27168.cpp.

int get_max_position (  )

Get the motor maximum position (int steps not degress)

Returns:
maximum position

Definition at line 34 of file Stepper_Motor_X27168.cpp.

int get_speed (  )

Get the motor speed (i.e.

number of steps per second)

Returns:
steps per second

Definition at line 24 of file Stepper_Motor_X27168.cpp.

void init (  )

Initialize the motor by rotating CW for full range and CCW for full range.

Definition at line 100 of file Stepper_Motor_X27168.cpp.

void set_max_position ( int  p )

Set the maximum steps the motor should take (not degrees)

Parameters:
pmaximum_steps :(ignored if parameter is greater than 629, the physical limit of the motor)

Definition at line 28 of file Stepper_Motor_X27168.cpp.

void set_speed ( float  s )

Set the motor speed (i.e.

number of steps per second) Motor will malfuntion is speed is faster than the the maximum capability if the motor.

Parameters:
ssteps per second : lower number makes the turn slower (default = 1000)

Definition at line 20 of file Stepper_Motor_X27168.cpp.

int step ( int  dir )

Parameters:
dir0 CLOCKWISE/FORWARD 1 ANTI-CLOCKWISE/REVERSE 2 STOP
Returns:
current_position of the motor

Definition at line 38 of file Stepper_Motor_X27168.cpp.

void step_position ( int  pos )

Turn the motor to a specific step.

Parameters:
posdesired position in steps (0-max_position)

Definition at line 80 of file Stepper_Motor_X27168.cpp.
