Thread Management:
Changed MeasurementThread to inherit from QThread instead of QObject
Added proper thread cleanup in reconnect_device()
Added checks for thread existence before attempting operations
Error Handling:
Added more robust error handling around thread operations
Ensured proper cleanup of resources during reconnection attempts
Added checks for thread running state before attempting to stop it
Initialization:
Explicitly initialized thread variables to None
Added proper null checks before accessing thread methods
Device Reconnection:
Improved the reconnection flow with better cleanup
Added status messages to keep user informed
(D)
Initialization Order:
Moved all attribute initializations to the start of __init__
Specifically initialized self.test_phase = "Idle" before it's used
UI Setup:
Now safely sets the phase label text after self.test_phase is initialized
Ensures all attributes exist before they're accessed
Error Prevention:
The QStandardPaths warning is still suppressed
All UI elements are properly initialized before use
(D)
Initialization Order:
Now initializes all data structures (time_data, voltage_data, etc.) in __init__ before they're used
Initializes device after UI setup using QTimer.singleShot
Error Handling:
Properly handles the case when no ADALM1000 is detected
Disables the start button until a device is connected
Device Connection:
Shows clear status messages about device connection state
Provides a reconnect button for manual reconnection attempts
Thread Safety:
Ensures all data structures exist before any thread tries to access them
(D)
Key changes made:
Added os.environ['QT_LOGGING_RULES'] = 'qt.qpa.*=false' at the beginning to suppress the QStandardPaths warning.
Added QGridLayout to the imports from PyQt5.QtWidgets.
Fixed the display layout section to properly use QGridLayout.
Made sure all necessary Qt classes are imported at the top of the file.
(D)
Key Changes in the Migration:
Threading Model:
Replaced Tkinter's after() with Qt's signal/slot mechanism
Created a proper QThread for continuous measurements
Used Qt's built-in threading for better integration
UI Structure:
Replaced Tkinter widgets with Qt equivalents (QMainWindow, QWidget, QVBoxLayout, etc.)
Used Qt's layout system instead of pack/grid
Implemented styling with Qt's stylesheet system
Event Handling:
Replaced Tkinter's command callbacks with Qt's signal/slot connections
Used pyqtSlot decorators for cleaner event handling
Plotting:
Switched to Qt's FigureCanvas backend for matplotlib
Maintained the same plotting functionality but with Qt integration
Error Handling:
Replaced Tkinter messageboxes with Qt's QMessageBox
Improved error handling with proper Qt signal propagation
Cleanup:
Implemented proper cleanup in closeEvent instead of protocol handlers
Ensured proper thread termination on exit
(D)
Test phase display issue: When continuous mode is disabled and the discharge voltage is already below cutoff, the phase still shows "Discharge" instead of switching to "Idle".
Graph update issue: The plot sometimes fails to update when starting a new test series.
(Deepseek)
✅ User unchecks Continuous Mode during discharge:
Status updates immediately: "Continuous Mode disabled..."
Discharge continues until cutoff voltage.
Test stops after discharge (no rest phase or new cycle).
✅ User leaves Continuous Mode enabled:
Test continues looping indefinitely (original behavior).
(D)
This makes the stop operation more thorough and provides better visual feedback to the user. The plot will now clearly show that the test has been stopped and reset.
(D)
This change ensures that:
The plot data buffers are cleared
The plot lines are reset to empty data
The axes are reset to default ranges (0-1)
The canvas is redrawn to show the cleared plot
(Deepseek)
Separate Log Files: You've successfully implemented separate log files for each cycle without cycle numbers in filenames.
1Hz UI Updates: The measurement display updates at 1Hz as requested.
Throttled Plot Updates: Plot updates are properly throttled to prevent lag.
Error Handling: Good error handling throughout the code.
Thread Safety: Proper use of threading for measurements and test sequences.
(Deepseek)
Show an error message when disconnected
Automatically attempt to reconnect
Keep retrying until successful
Provide clear status updates throughout the process
change cyclecount to beginning
This will ensure your plot:
Starts with a reasonable view of your expected voltage range
Maintains good visibility of the key areas (charge/discharge cutoffs)
Doesn't zoom out too far when there are measurement spikes
Has better overall framing of the data
Make all measurements update live in the GUI
Allow the stop button to immediately halt the test at any point in the cycle
Still maintain proper cleanup and data saving when stopped
(Deepseek)
Reducing unnecessary GUI updates
Implementing buffered file I/O
Throttling plot updates
Only updating display elements when values change
Using more efficient drawing methods for the plot
(Deepseek)
Der Stop-Button setzt nur ein Flag (request_stop) statt sofort zu stoppen
Die Entladephase überprüft dieses Flag und bricht ab, wenn es gesetzt ist
Nach der Entladephase wird der Test nur beendet, wenn request_stop True ist
Neue finalize_test Methode für konsistente Aufräumarbeiten
Klare Statusmeldungen, die den Stop-Request anzeigen
(Deepseek)
Die Statusmeldung zeigt jetzt klar an, ob:
Der Test normal weiterläuft ("Next: Charge to X.XV")
Auf einen Interrupt gewartet wird ("Waiting for interrupt"
Der Code prüft häufiger auf Interrupts, besonders zwischen den einzelnen Phasen
Bei einem Interrupt wird der aktuelle Zyklus noch sauber zu Ende geführt, aber kein neuer gestartet
Die Abschlussmeldung zeigt jetzt an, nach welchem Zyklus der Test unterbrochen wurde
(Deepseek)
Cycling added
Ich werde eine neue Variable continuous_mode hinzufügen, um den kontinuierlichen Betrieb zu steuern
Die run_test_sequence() Methode wird modifiziert, um in einer Schleife zu laufen
Die stop_test() Methode wird erweitert, um den kontinuierlichen Modus zu beenden
(Deepseek)
