New Settings > General > "Developer mode" checkbox (default on, so
this repo's simulate-by-default workflow is unaffected out of the box)
persisted through the existing core/app_settings.py load/save
functions. Exposed to code that can't easily receive the settings dict
via core.app_settings.is_developer_mode()/set_developer_mode(), a
small in-memory cache MainWindow keeps in sync whenever settings are
loaded or applied.
Debug window (ui/windows/debug_window.py): minimal first pass per the
plan — a live console. core/debug_log.py tees stdout/stderr into a
ring buffer + Qt signal (installed once in main.py, before anything
prints), so the window shows everything printed since app start,
including from background poll threads, not just what's printed while
it happens to be open. Its toolbar button is hidden unless developer
mode is on.
Simulate gating: every device's Simulation Mode checkbox/dropdown is
now hidden when developer mode is off — ui/add_device_dialog.py (also
covers the motion_capture camera panel, which shares this same
checkbox rather than having its own), and the per-device config
widgets in analog_input.py, arduino_device.py, digital_io.py,
nidaqmx_device.py, serial_device.py. Hiding rather than force-clearing
an already-simulating device's state — an existing simulated device
keeps working if developer mode is turned off later; the option is
just not offered again until it's back on.

- 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

Root cause: PlotWindow deepcopied _chart._cfg on init, so refresh_channels()
operated on a stale copy. Also, when _win_plot was None, _on_derived_changed
did nothing to prepare the config for when it opened.
Fix:
- refresh_channels() now owns the derived-pane sync: adds panes for new
virtual channels (updating BSP tree), removes panes for deleted ones
- _open_plot always passes current _chart._cfg reference then calls
refresh_channels() so derived panes sync on every open
- _on_derived_changed syncs cfg reference before calling refresh_channels()

Loaded settings were never consumed — theme defaulted to dark and
poll interval stayed at 100 ms regardless of what was saved to disk.

- 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

Reflects current design: split Physical/Virtual Channels layout,
no tabs, no legacy Signals list as primary UI.

- Remove redundant Signals tab from Channels window; PipelineTab is now direct content
- PipelineTab removes stale blocks when devices are removed or reconfigured
- Devices>Signals tab refreshes automatically on device add/remove/configure
- Channel name and unit edits in Devices>Signals propagate live to Channels pipeline block headers; missing blocks auto-added if channel is enabled

- Add missing QGroupBox import to settings_window (caused silent crash on open)
- Remove Controls tab and _controls_tab() method from settings
- Clamp child window positions to screen bounds so they don't go off-screen on Windows when main window is maximized
- Apply same screen-clamp fix to Motion Capture plugin window
- Delete example plugin; disable it in enabled.json

Tracks a user-selected point via webcam (OpenCV CSRT tracker) and
streams x_pos / y_pos pixel coordinates as live channels into the
acquisition pipeline. Falls back to a Lissajous figure simulation
when opencv-python is not installed, so the plugin works immediately
without hardware.
- tracker.py: background thread, real camera + sim modes, thread-safe API
- device.py: BaseDevice reading x/y from tracker, wires into engine
- filter.py: custom pixel_to_mm filter (registered in FILTER_CLASSES)
- window.py: floating tool window, live feed, click-to-track ROI selection
- plugin.py: LabPlugin wiring all pieces together, toolbar button,
settings widget, profile save/restore
Also: PluginAction.button_ref_callback lets plugins store a ref to their
toolbar button so they can uncheck it when their window closes.
opencv-python install note added to requirements.txt.

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.
