Preparing for alpha release!

1.0.0

⚠ ALPHA RELEASE - USE WITH CAUTION ⚠

The first alpha release for the new Joulescope UI 1.x. Limited testing performed. This release may crash and lose data. Not recommended for production use without thorough understanding of the issues listed below.

This release features a major overhaul to the Joulescope UI. The prior Joulescope UI 0.10.x and earlier has been an excellent tool for the past 4 years, but several major architectural choices hampered new feature development and full JS220 support.

Key improvements coming in the 1.x release series include:

• Full JS220 feature support.
• Greatly improved waveform widget.
• Support for multiple, simultaneously connected Joulescopes.
• Langauge localization.

While all of these features are underway, they are not all ready. This first alpha release nearly reaches feature parity with the previous 0.10.x release.

Tips for use

• Settings are still a work in progress. If you get stuck, select File → Exit and clear config. You can also manually delete the settings file.
  • Windows: %LOCALAPPDATA%\joulescope\config\joulescope_ui_config.json
  • macOS:

Features temporarily removed

The Joulescope UI 1.x is reconstructed. We started from a stripped-down application and migrated / ported code back in. We have not yet completed this process. Here are the features that are knowingly not included in this release:

• JLS v1 read support.
• Waveform
  • analysis tools (range tools) including USB inrush.
  • text annotations.
  • Panning using summary waveform.
  • Save/load annotations to/from file.
  • y-axis zoom and pan.
  • y-axis logarithmic scale.
• Manage (add / delete / reorder) Views.
• Global settings / style / preferences management.
• Only dark mode for now: no light or system.
• Click to copy from Value (Multimeter & Value) widget.
• Units selection for mAh and mWh.
• Plugin architecture, which was never fully completed, will be reintegrated but with new API #14.
• Most-recently used support
  • File → Open Recent
  • Path management
• ALL key bindings (no key presses work for now)

If you find other missing features, please post on the Joulescope forum.

Known issues

• Style settings linked between widgets of same class.
• Waveform
  • JS220 current range, GPI and trigger channels are time shifted from current, voltage, and power.
  • Missing clear streaming buffer button / feature.
  • Top summary waveform is not correct on file open until zoom/pan.
  • Crops view to extents of minimal signal. This avoids a JLS v2 rd_fsr_statistics PARAMETER_INVALID[5] when reading beyond bounds.
• Lots of unused 0.10.x code in repo that needs to be pruned.
• JS220 cannot stream all channels simultaneously.
• "Settings" menu does not open to nice sizes.
• JLS v2 file format does not yet implement corrupted file recovery.

JS220 features still not implemented

• Soft-fuse
• UI support for triggers
• Precision UTC time sync (existing UTC time only accurate to ~100 ms)
• UTC time sync between JS220's
• UART in / out
• On-instrument downsampling (host-side downsampling works great)
