Description
hw_stepper_motor_position(hw_stepper_motor_id, position) hw_stepper_motor_position(hw_stepper_motor_id, position, direction)
hw_stepper_motor_position is used to set the position of of the stepper motor.
Return value
This function won't return a value.
Arguments
| # | Argument | Type | Description |
|---|---|---|---|
| 1 | hw_stepper_motor_id | Object | The is the reference to the stepper motor. You can get this reference from the hw_stepper_motor_add function. |
| 2 | position | Number | The desired position, ranging from 0.0 to 1.0. |
| 3 | direction | String | (Optional) The desired direction. Can be "SLOWEST", "FASTEST", "CLOCKWISE", "COUNTERCLOCKWISE", "ENDLESS_CLOCKWISE", "ENDLESS_COUNTERCLOCKWISE" or "STOP" (from AM/AP 3.7). Defaults to "FASTEST". |
Example
-- Initiate stepper motor with:
-- 2048 steps
-- 10 rpm speed
-- On pins A2, A3, A4 and A5 of an Arduino Nano
id = hw_stepper_motor_add("DIRECT_4WIRE", 2048, 10, "ARDUINO_NANO_A_D2", "ARDUINO_NANO_A_D3", "ARDUINO_NANO_A_D4", "ARDUINO_NANO_A_D5")
-- Set position to 75%
hw_stepper_motor_position(id, 0.75, "CLOCKWISE")
-- Rotate stepper motor endless
hw_stepper_motor_position(id, nil, "ENDLESS_CLOCKWISE")
