navigate.model.devices.daq.asi.ASIDaq

class navigate.model.devices.daq.asi.ASIDaq(microscope_name, device_connection, configuration: Dict[str, Any], device_id)

Bases: DAQBase, SerialDevice

ASIDAQ class for Data Acquisition (DAQ).

Representation of Tiger Controller in action. Triggers all devices and outputs to camera trigger channel.

__init__(microscope_name, device_connection, configuration: Dict[str, Any], device_id) → None

Initialize the ASI DAQ.

Parameters:
  • microscope_name (str) – Name of the microscope.

  • device_connection (Any) – Connection to the Tiger Controller.

  • configuration (Dict[str, Any]) – Dictionary of configuration parameters.

  • device_id (int) – Parameter necessary for start_device but not used here.

Methods

__init__(microscope_name, device_connection, ...)

Initialize the ASI DAQ.

calculate_all_waveforms(microscope_name, ...)

Pre-calculates all waveforms necessary for the acquisition and organizes in a dictionary format.

connect(port[, baudrate, timeout])

Build ASIDaq Serial Port connection

disconnect()

Disconnect from serial device.

enable_microscope(microscope_name)

Enables the microscope.

prepare_acquisition(channel_key)

Prepare the acquisition.

run_acquisition()

Run DAQ Acquisition.

stop_acquisition()

Stop Acquisition.

Attributes

wait_to_run_lock

Lock for waiting to run.

is_updating_analog_task

Flag for updating analog task.

analog_outputs

Analog output tasks.

daq

Device connection.

microscope_name

microscope name

zoom

zoom

calculate_all_waveforms(microscope_name, exposure_times, sweep_times)

Pre-calculates all waveforms necessary for the acquisition and organizes in a dictionary format.

Parameters:
  • microscope_name (str) – Name of the active microscope

  • exposure_times (dict) – Dictionary of exposure times for each selected channel

  • sweep_times (dict) – Dictionary of sweep times for each selected channel

Returns:

self.waveform_dict – Dictionary of waveforms to pass to galvo and ETL, plus a camera waveform for display purposes.

Return type:

dict

classmethod connect(port, baudrate=115200, timeout=0.25)

Build ASIDaq Serial Port connection

Parameters:
  • port (str) – Port for communicating with the filter wheel, e.g., COM1.

  • baudrate (int) – Baud rate for communicating with the filter wheel, default is 115200.

  • timeout (float) – Timeout for communicating with the filter wheel, default is 0.25.

Returns:

tiger_controller – ASI Tiger Controller object.

Return type:

TigerController

disconnect()

Disconnect from serial device.

enable_microscope(microscope_name: str) → None

Enables the microscope.

Parameters:

microscope_name (str) – Name of the active microscope

prepare_acquisition(channel_key: str) → None

Prepare the acquisition.

Creates and configures the DAQ tasks. Writes the waveforms to each task.

Parameters:

channel_key (str) – Channel key for current channel.

run_acquisition() → None

Run DAQ Acquisition.

Run the tasks for triggering, analog and counter outputs. The master trigger initiates all other waveforms via a shared trigger For this to work, all analog output and counter tasks have to be primed so that they are waiting for the trigger signal.

stop_acquisition() → None

Stop Acquisition.

Stop control loop.

analog_outputs

Analog output tasks.

Type:

dict

camera_delay

Camera delay percentage

Type:

float

configuration

Dictionary of configuration parameters

Type:

dict

daq

Device connection.

Type:

Any

daq_parameters

Dictionary of DAQ parameters

Type:

dict

exposure_times

exposure times for different channels

Type:

dict

is_updating_analog_task

Type:

dict

wait_to_run_lock

Lock for waiting to run.

Type:

Lock

waveform_constants

Dictionary of waveform constants

Type:

dict

waveform_dict

Dictionary of waveforms.

Type:

dict

waveform_expand_num
