class EncoderUnit
Constructors
Methods
- EncoderUnit.get_rotary_increments() int
Gets the rotation increment of the Rotary object. Can be used to determine the direction of rotation.
UIFLOW2:
- EncoderUnit.set_rotary_value(new_value: int) None
Sets the rotation value of the Rotary object.
- 参数:
new_value (int) – adjust the current value.
