FFT Visualizer-Multiple EEG & FFT Visualization #43
Conversation
|
""" WalkthroughThe updates introduce significant enhancements across multiple components. The backend now supports multi-threaded, precise, and unified data handling for BLE, Wi-Fi, and USB protocols, with robust cleanup and sample rate monitoring. The frontend JavaScript adds centralized error logging, dynamic app status tracking, improved filename management, and resilient UI state handling. The EEG application is refactored for modular, multi-channel real-time analysis with user-configurable plots. Documentation and ignore rules are updated to reflect new features and usage patterns.

291-294: Main-loop exit condition depends solely onusb_runningWith the current logic the main thread spins as long as
usb_runningisTrue, regardless of whether the handler thread is actually alive.
After addressing the flag-reset issue, also consider checkingself.usb_thread.is_alive()to avoid rare edge cases where the flag and thread state diverge.Example:
while manager.usb_running and manager.usb_thread.is_alive(): time.sleep(1)

14-58: Settings dialog implementation looks good!The new
SettingBoxdialog class is well-structured and provides a clear interface for users to select which EEG channels to display and which channel to use for brainpower calculations. The validation logic ensures that at least one EEG channel is always selected.

174-185: Sound implementation of per-channel buffers and filter states.The changes correctly implement per-channel circular buffers, indices, and filter states to support independent processing of multiple EEG channels. This is a necessary foundation for the multi-channel visualization feature.
379-392: Improved brainwave power calculation with frequency range checks.The changes correctly add checks to ensure frequency ranges exist before calculating power values, and improve the debug output to include the selected channel information.

245-252: Thread shutdown race condition with short timeoutThe USB thread is given only 1 second to exit, which may not be enough if it's blocked on I/O operations. The code then proceeds to close the serial port, which can cause exceptions in the still-running thread.
Does the USB thread reliably shut down within the 1-second timeout? You can check this by modifying the cleanup method to monitor if the thread is still alive after the timeout:
#!/bin/bash # Search for any logging related to thread state during cleanup rg -A 5 -B 5 "thread.*is_alive|alive.*thread" --no-heading
159-176:⚠️ Potential issueUSB thread terminates without resetting

173-176: High frequency polling may cause performance issuesThe app status is checked every 200ms, which results in 5 requests per second per app. This could lead to excessive network traffic and server load, especially with many apps.
// Periodically check all app statuses function startAppStatusChecker() { checkAllAppStatuses(); - setInterval(checkAllAppStatuses, 200); + setInterval(checkAllAppStatuses, 1000); // Check once per second instead }
104-140: App click handler does not use fetched app status dataThe function fetches the app status but doesn't use that data to determine if the app is already running before launching it. It only checks the visual indicator through the DOM.
async function handleAppClick(app, card) { const statusElement = document.getElementById(`status-${app.script}`); if (statusElement && !statusElement.classList.contains('hidden')) { return; } if (!isConnected) { showAlert('Please connect to a device first using USB, WiFi or Bluetooth'); return; } const originalContent = card.innerHTML; // Add loading state to the clicked card card.innerHTML = ` <div class="h-full flex items-center justify-center p-4"> <i class="fas fa-circle-notch fa-spin text-${app.color}-500 text-xl mr-2"></i> <span>Launching ${app.title}...</span> </div> `; try { const response = await fetch(`/check_app_status/${app.script}`); if (!response.ok) { throw new Error('Failed to check app status'); } const data = await response.json(); + + // Verify app is not already running based on server response + if (data.status === 'running') { + showAlert(`${app.title} is already running`); + card.innerHTML = originalContent; + updateAppStatus(app.script); + return; + } await launchApplication(app.script); card.innerHTML = originalContent; updateAppStatus(app.script); // Update status after launch } catch (error) { console.error('Error launching app:', error); showAlert(`Failed to launch ${app.title}: ${error.message}`); card.innerHTML = originalContent; } }
865-895: Inconsistent disconnection status messagesThe code uses different status messages for disconnection in different places: "Disconnected!" vs "Stream disconnected!". Consider using consistent messaging for better user experience.
function handleDisconnection() { isConnected = false; disconnectBtn.classList.add('hidden'); disconnectingBtn.classList.add('hidden'); connectingBtn.classList.add('hidden'); connectBtn.classList.remove('hidden'); - showStatus('Stream disconnected!', 'fa-times-circle', 'text-red-500'); + showStatus('Disconnected!', 'fa-times-circle', 'text-red-500'); // Reset protocol buttons connectionBtns.forEach(btn => { btn.disabled = false; btn.classList.remove('bg-cyan-600', 'dark:bg-cyan-700', 'cursor-default'); btn.classList.add('hover:bg-cyan-500', 'hover:text-white'); }); // Handle recording state if (isRecording) { isRecording = false; recordBtn.innerHTML = 'Start Recording'; recordBtn.classList.remove('bg-gray-500'); recordBtn.classList.add('bg-red-500', 'hover:bg-red-600'); recordingStatus.classList.add('hidden'); filenameInput.disabled = false; - showStatus('Recording stopped (stream lost)', 'fa-stop-circle', 'text-red-500'); + showStatus('Recording stopped (connection lost)', 'fa-stop-circle', 'text-red-500'); } if (eventSource) { eventSource.close(); eventSource = null; } }

11-11: Appropriate import for directory operations.The
osmodule is required for the new directory operations in the/log_errorendpoint.
83-84: Clean refactoring of stream status check.The refactored code elegantly uses
hasattr()to check for the existence of thestream_activeattribute before accessing it, reducing code complexity while maintaining functionality.static/script.js (17)
1-23: Well-implemented error logging mechanism with recursion protection.The new centralized error logging function correctly implements:
- Protection against recursive logging with the
isLoggingflag- Proper error formatting with timestamps
- Server-side logging with fallback to console
- Comprehensive error object handling (stack, message, or toString)
This provides a robust foundation for client-side error reporting.
48-48: Consistent error logging replacement.All console error calls are replaced with the new centralized
logError()function, providing consistent error handling throughout the application.Also applies to: 77-77, 160-160, 192-192, 459-459, 600-600, 713-713, 734-734, 781-781, 807-807, 885-885
128-164: New app click handler with proper status verification.The
handleAppClickfunction properly:
- Checks if the app is already running before attempting to launch
- Verifies connection status
- Adds visual loading state during launch
- Handles errors and restores the original button state
166-194: Comprehensive app status update function.The
updateAppStatusfunction effectively:
- Fetches the running status of the app
- Updates visual indicators (showing/hiding status elements)
- Adjusts CSS classes to visually disable running apps
- Properly handles the cursor styles and interactivity
197-212: Efficient periodic app status checking.The status checker implementation:
- Runs checks at appropriate intervals (200ms)
- Uses element selectors efficiently to find all app cards
- Extracts app names correctly from element IDs
317-335: Useful timestamp updater for filename input.The timestamp updater:
- Updates the filename at appropriate intervals (1 second)
- Only updates when not recording
- Intelligently handles both placeholder and value to maintain consistent naming
- Preserves custom filenames entered by users
379-382: Improved initialization of filename input.The updated initialization properly:
- Ensures the input is enabled initially
- Sets appropriate CSS classes for light/dark mode
- Starts the timestamp updater
572-572: Connection polling timeout increased for better reliability.Increasing the connection polling timeout from 5 to 15 seconds provides more time for the connection to establish, which can be particularly important for slower connections or when there are network issues.
771-777: Improved recording stop handling with proper input state management.The code now properly:
- Re-enables the filename input after stopping recording
- Restores appropriate CSS classes for light/dark mode
- Updates the timestamp for the filename
- Shows a status message to the user
798-803: Appropriate input state management when recording starts.The code properly:
- Disables the filename input during recording
- Applies appropriate CSS classes for visual feedback
- Shows a status message to indicate recording has started
820-820: Improved status indicator.The changes:
- Standardize the icon color to white for better visibility
- Extend the status display duration from 2 to 3 seconds, giving users more time to notice
Also applies to: 824-824
838-838: Connection status synchronization.The code now correctly calls
handleConnectionSuccess()when a connection is detected, ensuring UI state is properly synchronized with the backend connection status.
850-850: Improved disconnection handling with proper user feedback.The code now:
- Centralizes disconnection handling by calling
handleDisconnection()- Shows a status message to inform the user of the disconnection
Also applies to: 856-856
868-874: Comprehensive handling of disconnection during recording.The code properly:
- Re-enables the filename input if recording was stopped due to disconnection
- Restores appropriate CSS classes
- Shows a clear status message explaining why recording stopped
889-919: Centralized disconnection handler function.The new
handleDisconnection()function properly:
- Resets connection state variables
- Updates UI button states
- Shows status message
- Resets protocol buttons
- Handles recording state cleanup
- Closes event sources
This centralization improves code maintainability and ensures consistent behavior.
930-932: Global error handler for improved error reporting.The window.onerror handler captures uncaught errors and forwards them to the centralized logging system. This is an excellent defensive programming practice that helps catch errors that might otherwise go unreported.
676-676: Consistent disconnection status message.The disconnect button handler now shows a "Disconnected!" status message on successful disconnect, consistent with other disconnection messaging in the application.

3-3: Remove unused import.The
QGridLayoutimport is not used in the code and should be removed to keep imports clean.-from PyQt5.QtWidgets import (QApplication, QVBoxLayout, QHBoxLayout, QMainWindow, QWidget, QGridLayout, QScrollArea, QPushButton, QDialog, QCheckBox, QLabel, QComboBox, QFrame, QSizePolicy) +from PyQt5.QtWidgets import (QApplication, QVBoxLayout, QHBoxLayout, QMainWindow, QWidget, QScrollArea, QPushButton, QDialog, QCheckBox, QLabel, QComboBox, QFrame, QSizePolicy)
129-173: LGTM! Clear channel selection dialog.The
SettingBoxprovides a clean interface for channel selection with proper validation ensuring at least one EEG channel is always selected.Consider adding user feedback when automatically selecting Channel 1:
def validate_and_accept(self): # Ensure at least one EEG channel is selected eeg_selected = any(cb.isChecked() for cb in self.eeg_checkboxes) if not eeg_selected: + # Could add a message box here to inform user self.eeg_checkboxes[0].setChecked(True) self.accept()

23-62: LGTM! Well-designed data processing class.The
DataProcessorclass implements proper EEG signal filtering and buffering:
- Appropriate filter design (50Hz notch + 0.5-45Hz bandpass)
- Efficient circular buffer implementation for real-time processing
- Per-channel independent processing
63-128: LGTM! Robust FFT analysis implementation.The
FFTAnalyzerclass implements proper FFT computation with:
- Correct Hanning windowing and amplitude scaling
- Standard EEG frequency band definitions
- Smoothing for stable visualization
- Relative power calculation for brainwave analysis
The debug output limited to channel 0 is a good design choice to prevent console spam.
174-207: LGTM! Well-structured initialization.The initialization properly:
- Establishes LSL connection with graceful failure handling
- Initializes processing components with correct parameters
- Sets up default channel selections
- Configures UI and update timer
208-231: LGTM! Robust LSL connection handling.The method properly handles LSL stream discovery and connection with appropriate error handling and user feedback.
232-312: LGTM! Well-designed UI layout.The horizontal split layout with scrollable EEG plots and dedicated analysis panels provides an intuitive and scalable interface for multi-channel EEG monitoring.
313-355: LGTM! Comprehensive plot initialization.The method efficiently handles multi-channel plot creation with proper cleanup, color coding, and visibility management.
356-366: LGTM! Proper visibility management.The method correctly updates plot visibility based on user selection. The static analysis warning about unused
curvevariable is a false positive - it's properly used as part of tuple unpacking.
367-378: LGTM! Efficient settings dialog handling.The method properly manages the settings dialog with change detection to avoid unnecessary updates.
379-396: LGTM! Robust real-time data processing loop.The main update method properly handles LSL data streaming with appropriate timeout handling and disconnection detection.
397-420: LGTM! Clean separation of plot update logic.The individual plot update methods are well-designed with proper channel selection filtering and efficient data flow from processing components to visualization.
