Changelog¶

Next bugfix release

[Bug]: issue with ctypes imports in daq_utils on macos Now ok
[Bug]: DAQ_Scan: when no live plot is possible (too high dimensionality) no more scan datas are saved
[Bug]: Navigator: double click option sends the clicked position to connected slots
[Bug]: viewer1D displayed incorrectly the legend, now fixed

[Feature]: added a field ‘acq_time_s’ in the exported data from each viewer. To be used to track at what time a given dataset has been recorded
[Feature]: creation of the H5Saver object: simplifies the data saving from pymodaq modules and adds all mandatory metadata
[Feature]: Uniformity of the saved h5 files. Axes labels and units are added as metadata and displayed in H5Browser
[Feature]: Viewers: exported data now contains axis information as a dict containing data (values of the axis), label and units and type of data (raw or generated from a ROI)
[Feature]: pid_controller module added in daq_utils module: enable a PID loop using pymodaq modules and custom written PID models (see documentation)
[Feature]: pid_controller module modified to work in a parallel thread
[Feature]: DAQ_Scan module has now its acquisition loop within a parallel thread
[Feature]: The pid_module can be used as an actuator within DAQ_Scan (using the preset_manager configuration)
[Feature]: Viewer 1D and 2D share now the same object ROIManager to deal with their regions of interest
[Feature]: DAQ_Scan module’s H5Saver object has now by default the option to not save the ROI generated data. Only the live plots datas are still saved by default.

[Feature]: module scanner (daq_utils.scanner) has been created. Deals with lines or area selections within any viewer2D modules. Used for DAQ_Scan and some others plugins (for area selection if needed). Most of the scan type settings (of daq_scan) have been moved to scanner that is now a subobject of daq_scan
[Feature]: h5_browser: a right click on tree items shows a context menu. so far possibility to export current item (data) in ascii text file (%.6e precision format).
[Feature]: all modules: debug info contains now name of package, method and script line where the error has been generated

[Feature]: DAQ_Move_plugins: added the _controller_units parameter. Holds the native units used with the Move instance
[Feature]: DAQ_Scan: added the navigator option. It is a 2D area-like object where to define scans. All 2D scans in the current h5file are plotted in this area and at their corresponding position. Each scan plotability can be set.

[Feature]: DAQ_Scan updated with averaging possibility. Opens up a new dock showing the current scan average. All scan in the average are saved
[Feature]: DAQ_Scan: Overshoot configuration is now available: set DAQ_Move actions depending on detected values
[Feature]: DAQ_Scan: possibility to save all datas in independent files or not (default is not)
[Feature]: DAQ_Scan: Huge modification related to the scanning. Now you can select an area in one of the opened 2DViewers This viewer could for instance be a calibrated camera referring to the x and y positions of a XY stage. The Plot2D scan 2D viewer can also be used. Say that you just did a 2D scan and now you want to scan a cross-section within!! This area can be a 2D one (rectangle, 2D scan type) or a PolyLines (linked segments, 1D scan type). Random modes and others are still available in this mode

[Feature]: Tested entry-points after installation.*.exe files created successfully with manual setup install. But the link to working python is missing with pip install (python.exe and pythonw.exe) must be on the PATH
[Feature]: Moved the preset_mode folder out the pymodaq tree, but relative to HOMEPATH (windows) or HOME (linux & OSX) environment variable
[Feature]: When started from DAQ_scan, all Quit pushbutton are disabled within individual Move and Viewer modules.
[Feature]: removed plugins from tree structure. May be installed from github or pypi as external library

[Feature]: Renamed all modules with lowercase. Renamed image viewer_multicolor as viewer2D
