class navigate.model.devices.shutter.ni.NIShutter(microscope_name: str, device_connection: Any, configuration: Dict[str, Any], *args: Optional[Any], **kwargs: Optional[Any])

Bases: ShutterBase

ShutterTTL Class

Triggering for shutters delivered from DAQ using digital outputs. Each output keeps their last digital state for as long the device is not powered down.

__init__(microscope_name: str, device_connection: Any, configuration: Dict[str, Any], *args: Optional[Any], **kwargs: Optional[Any]) → None

Initialize the ShutterTTL.

Parameters:

• microscope_name (str) – Name of microscope in configuration
