Joulescope

2019 Oct 9

* Converted JSON5 config_def to python to improve start time.
* Updated to latest pyqtgraph.
* Improved waveform performance by only updating curve fill when needed.

2019 Oct 3

* Added NaN checks in multimeter when accumulating (Issue 2).
* Added configurable stream buffer duration (was fixed at 30 seconds).
* Added general-purpose input (GPI) support.
* Only update oscilloscope when visible (improve performance).

2019 Sep 22

* Only display mean for signal markers when zoomed to single sample.

2019 Sep 20

* Fixed log warning for on_fps_timer.
* Fixed error that prevented "Export data" on open JLS file.
* Sign macOS distribution and application.

2019 Sep 17

* Fixed "record" function not working on Windows due to multiprocessing and
pyinstaller EXE packaging.
* Applied calibration to "zoomed-out" data on dual marker export. All existing
files created with dual marker export are invalid when the view window is
more than a couple seconds (actual duration varies), but the zoomed-in
data is still valid.

2019 Sep 16

* Added plugins and range_tool. Refactored export & USB Inrush.
* Added histogram-based plugins (author Axel Jacobsen).
* Updated pyqtgraph
* Added RangeToolInvocation methods marker_single_add and marker_dual_add.
* Added check and UI status warning when device does not support dual markers.
* Improved logging.
* Added range_tool plugins submenus.
* Added fault handler (such as segmentation faults) output to log.
* Modified dual marker delta time to display in engineering notation.
* Updated the getting started guide.
* Persisted accumulated charge/energy across device disconnect/connect.
* Fixed single marker to display "No data" over missing samples.
* Fixed y-axis waveform autoranging when min/max traces are not shown.
* Modified codebase to use new joulescope.Driver StreamProcessApi,
elimination of recording_start and recording_stop.
* Implemented improved frame rate limiting.
* Refactored to support new data_update format with integrated view details.
* Added Δt indication for statistics computed over visible window.
* Moved RecordingViewerDevice to operate in its own thread for improved
performance. Allows software to condense multiple requests, such as
during mouse click & drag.
* Moved JLS recording to its own process so that OS file write stalls do
not cause sample drops.
