Descriptions of the exported functions:

fnTurn_motor1:
	Description:
		This function performs all of the motor rotation on motor1. It accepts one integer parameter. The parameter specifies the number of steps motor1 is to turn. The speed, direction, parallel port address, and other variables are set by other functions.
[Top]
fnTurn_motor2:
	Description:
		This function performs all of the motor rotation on motor2. It accepts one integer parameter. The parameter specifies the number of steps motor2 is to turn. The speed, direction, parallel port address, and other variables are set by other functions.

fnTurn_motor3:
	Description:
		This function performs all of the motor rotation on motor3. It accepts one integer parameter. The parameter specifies the number of steps motor3 is to turn. The speed, direction, parallel port address, and other variables are set by other functions.
[Top]
fnTurn_motor4:
	Description:
		This function performs all of the motor rotation on motor4. It accepts one integer parameter. The parameter specifies the number of steps motor4 is to turn. The speed, direction, parallel port address, and other variables are set by other functions.

[Top] DLLVersion:
	Description:
		This function returns the version of the StepperMotor DLL as a float value.
[Top] set_controller1:
	Description:
		This function set the parallel port used for controller 1. The values are: 1 - 0x378 2 - 0x278 3 - 0x3BC
[Top] set_controller2:
	Description:
		This function set the parallel port used for controller 2. The values are: 1 - 0x378 2 - 0x278 3 - 0x3BC
[Top] get_motor1_direction:
	Description:
		This function returns the value for the motor1 rotation direction variable. Each motor has two rotation directions. The default value for the motor is 0. A value of 1 causes the motor to rotate in the opposite direction.
[Top] get_motor2_direction:
	Description:
		This function returns the value for the motor2 rotation direction variable. Each motor has two rotation directions. The default value for the motor is 0. A value of 1 causes the motor to rotate in the opposite direction.
[Top] get_motor3_direction:
	Description:
		This function returns the value for the motor3 rotation direction variable. Each motor has two rotation directions. The default value for the motor is 0. A value of 1 causes the motor to rotate in the opposite direction.
[Top] get_motor4_direction:
	Description:
		This function returns the value for the motor4 rotation direction variable. Each motor has two rotation directions. The default value for the motor is 0. A value of 1 causes the motor to rotate in the opposite direction.
[Top] set_motor1_direction:
	Description:
		This function accepts an integer parameter to set the value for the motor1 rotation direction variable. Each motor has two rotation directions. The default value for the motor is 0. A value of 1 -- or any other integer than 0 -- causes the motor to rotate in the opposite direction.
[Top] set_motor2_direction:
	Description:
		This function accepts an integer parameter to set the value for the motor2 rotation direction variable. Each motor has two rotation directions. The default value for the motor is 0. A value of 1 -- or any other integer than 0 -- causes the motor to rotate in the opposite direction. .
[Top] set_motor3_direction:
	Description:
		This function accepts an integer parameter to set the value for the motor3 rotation direction variable. Each motor has two rotation directions. The default value for the motor is 0. A value of 1 -- or any other integer than 0 -- causes the motor to rotate in the opposite direction. .
[Top] set_motor4_direction:
	Description:
		This function accepts an integer parameter to set the value for the motor4 rotation direction variable. Each motor has two rotation directions. The default value for the motor is 0. A value of 1 -- or any other integer than 0 -- causes the motor to rotate in the opposite direction. .
[Top] get_delay_time:
	Description:
		This function returns the value of the current delay_time as evoked by the C Sleep() function call after each step is executed in the fnTurn function. The defualt value is set to 50.
[Top] set_delay_time:
	Description:
		This function accepts an integer parameter to set the value for the delay_time variable. The delay_time variable is evoked by the C Sleep() function call after each step is executed in the fnTurn function. The default value is set to 50. Values can typically range from 3 to the maximum integer size.
[Top] fn_Turn:
	Description:
		From oringial dll -- this function performs motor rotation. It accepts two integer parameters. The first one specifies the number of steps motor1 is to turn and the second one specifies the number of steps motor2 is to turn. The speed, direction, parallel port address, and other variables are set by other functions. fn_Turn_motor1, fn_Turn_motor2 can be used in place of this function.
[Top] fn_Turn2:
	Description:
		From oringial dll -- this function performs motor rotation. It accepts two integer parameters. The first one specifies the number of steps motor3 is to turn and the second one specifies the number of steps motor4 is to turn. The speed, direction, parallel port address, and other variables are set by other functions. fn_Turn_motor3, fn_Turn_motor4 can be used in place of this function.
[Top] get_input_S3:
	Description: (Not yet available)
		This function returns the value of the current S3 input. Either 1 or 0 is returned.
[Top] get_input_S5:
	Description:(Not yet available)
		This function returns the value of the current S5 input. Either 1 or 0 is returned.
