- Named variables in expressions: source channel IDs injected as Python
identifiers alongside x[] (e.g. write `A0 * 2` instead of `x[0] * 2`)
- Shared `vars` dict on SignalProcessor accessible from all expressions,
functions, and control scripts; persisted in .labdaq profiles
- Per-derived-channel `state` dict for persistent computation state in
custom scripts
- Control widgets gain optional on_action_script (Python snippet with
value, vars, channels, math in scope); syntax-checked in editor dialog
- Built-in derived kinds (derivative, rms, power, etc.) now show their
Python implementation as read-only code previews; "Edit as Custom Script"
converts to custom_script kind with template pre-filled

Profile integration:
- CameraDevice.get_save_config() serialises camera_index, simulate,
resolution, fps — cameras now persist in .labdaq profiles
- ProfileManager.register/unregister_device_factory() lets plugins
register their device classes for profile restoration without
core → plugin dependency
- MotionCapturePlugin registers CameraDevice factory on load/unload
Camera configuration:
- Add Frame Rate combo to CameraPanel (Default/15/24/30/60/120 fps)
defaults to 30 fps; flows through to CAP_PROP_FPS on connect
- tracker.start() accepts fps param alongside existing resolution
Tracking persistence:
- CameraTracker.is_running() — checks thread alive state
- MotionCaptureWindow initialises _connected from tracker.is_running()
so reopening the window resumes the live feed without restarting
the camera or losing the active tracking state
Window state:
- Plugin saves px_per_mm + camera_idx when window closes
- Reopened window restores saved values and syncs mode/shape UI
from tracker state via restore_ui_state() (signals blocked to
avoid resetting tracker)
- Window type changed to Qt.WindowType.Window for independent
close button on all Linux WMs

- New core/app_settings.py: load/save settings.json to platform config dir
(Windows: %APPDATA%, Linux: ~/.config, macOS: ~/Library/Application Support)
- MainWindow loads saved settings on startup, saves on every Apply & Close
- Settings survive profile switches and app restarts independently of profiles
- Settings > General: Reset to Defaults button with QMessageBox confirmation

- Split PipelineTab into Physical/Virtual sections via QSplitter
- Each section has independent scroll area, header, and add controls
- Add "With Respect To" control for derivative/second_derivative virtual channels: Time (dy/dt) or Channel (dy/dx)
- When Channel selected, x variable picker appears for any physical or derived channel
- signal_processor computes dy/dx using channel inputs when deriv_wrt=channel

Plugins live in plugins/<name>/ with a manifest.json and a LabPlugin
subclass. Enabled/disabled in Settings > Plugins tab; state persists in
plugins/enabled.json and in .labdaq profiles (loading a profile
enables/disables plugins to match). Plugins can contribute toolbar
buttons, BaseDevice instances (auto-wired into acquisition pipeline),
custom signal filter classes, a settings widget, and profile state via
get_save_state/apply_save_state. Load errors now report the exact
failing stage (file not found, class missing, on_load crash).
Includes example plugin skeleton and docs/plugin-development.md.

Fixed derived signal saving profile. Renamed Signals>Pipeline to Signas>Channels
and adding/removing channels feature.
|
|
|
|
|
|
Including:
- Control panel
- Change status of simulation after devices creation.
- Arduino serial conflict with multiple channels.
- Claude instructions.
- Update to arduino on board code.
|
|
This version contains the profile feature. Allowins users to save the
channels, signals and plots for specific labs.
