🧹 Nitpick comments (6)
test/beetle.py (3)
34-35: Document filter parameters and consider making them configurable.The notch and bandpass filter parameters are hardcoded. Consider:
- Adding comments explaining the filter choices (e.g., why 50Hz notch, 0.5-48Hz bandpass).
- Making these parameters configurable through command-line arguments or a config file.
72-78: Refactor global variable usage in update_beetle_position.The function uses a global variable which makes it harder to test and maintain. Consider passing the beetle position as a parameter.
-def update_beetle_position(focus_level, is_focus_stable): - global beetle_y +def update_beetle_position(current_y, focus_level, is_focus_stable, image_height): if is_focus_stable: - beetle_y = max(10 + beetle_image.get_height() // 2, beetle_y - focus_speed_upward) + new_y = max(10 + image_height // 2, current_y - focus_speed_upward) else: - beetle_y = min(580 - beetle_image.get_height() // 2, beetle_y + focus_speed_downward) + new_y = min(580 - image_height // 2, current_y + focus_speed_downward) + return new_y
96-97: Document and improve buffer management logic.The 20% buffer release is a magic number and the implementation could be more efficient.
- release_count = int(len(buffer) * 0.2) # Remove oldest 20% - buffer = buffer[release_count:] # Trim buffer + # Release 20% of the buffer to prevent memory growth while maintaining + # enough history for smooth analysis + BUFFER_RELEASE_RATIO = 0.2 + release_count = int(len(buffer) * BUFFER_RELEASE_RATIO) + buffer = buffer[release_count:]ffteeg.py (2)
77-78: Document the rationale for buffer sizes.The code uses fixed buffer sizes of 500 samples for both
eeg_dataandmoving_windowwithout explaining the choice.Add documentation:
- self.eeg_data = deque(maxlen=500) # Initialize moving window with 500 samples - self.moving_window = deque(maxlen=500) # 500 samples for FFT and power calculation (sliding window) + # Buffer size of 500 samples provides 1 second of data at 500Hz sampling rate, + # balancing between temporal resolution and computational efficiency + self.eeg_data = deque(maxlen=500) + # Separate moving window for FFT analysis with the same size to maintain + # consistent frequency resolution + self.moving_window = deque(maxlen=500)
118-120: Consider using scipy.signal.windows for window functions.The code uses numpy's Hanning window, but scipy.signal.windows provides more window options and better documentation.
+from scipy.signal import windows - window = np.hanning(len(self.moving_window)) + window = windows.hann(len(self.moving_window)) buffer_windowed = np.array(self.moving_window) * windowchords.py (1)
58-58: Document hardware specifications for new boards.New boards "GENUINO-UNO" and "BLACK-PILL" were added without documentation about their specifications or requirements.
Add documentation:
"UNO-CLONE": {"sampling_rate": 250, "Num_channels": 6}, # Baud Rate 115200 - "GENUINO-UNO": {"sampling_rate": 250, "Num_channels": 6}, + "GENUINO-UNO": {"sampling_rate": 250, "Num_channels": 6}, # Compatible with Arduino UNO R3 "UNO-R4": {"sampling_rate": 500, "Num_channels": 6}, "RPI-PICO-RP2040": {"sampling_rate": 500, "Num_channels": 3}, "NANO-CLONE": {"sampling_rate": 250, "Num_channels": 8}, # Baud Rate 115200 - "BLACK-PILL": {"sampling_rate": 500, "Num_channels": 10}, + "BLACK-PILL": {"sampling_rate": 500, "Num_channels": 10}, # STM32F4x1 based boardAlso applies to: 62-62

45-46: Verify the beetle image path and add error handling.The image loading code assumes
beetle.jpgexists in the current directory without any error handling.Add error handling:
-beetle_image = pygame.image.load('beetle.jpg') -beetle_image = pygame.transform.scale(beetle_image, (80, 80)) +try: + beetle_image = pygame.image.load('beetle.jpg') + beetle_image = pygame.transform.scale(beetle_image, (80, 80)) +except pygame.error as e: + print(f"Error loading beetle image: {e}") + pygame.quit() + exit()✅ Verification successful
The image path is correct, but error handling is recommended
The image file
beetle.jpgexists in the correct location (same directory astest/beetle.py). While the current path reference works, adding error handling as suggested in the review is still good practice to handle potential runtime issues like accidental file deletion or permission problems.🏁 Scripts executed

57-66: LGTM! Good hardware support expansion.The new board entries are well-structured and provide consistent configuration for sampling rates and channel counts.
89-95: Improve error handling in connect_hardware.The UnicodeDecodeError handling could be more informative and include retry logic.
- while response not in supported_boards and retry_counter < retry_limit: - ser.write(b'WHORU\n') # Check board type - try: - response = ser.readline().strip().decode() # Attempt to decode the response - except UnicodeDecodeError as e: - print(f"Decode error: {e}. Ignoring this response.") - response = None + while response not in supported_boards and retry_counter < retry_limit: + ser.write(b'WHORU\n') # Check board type + try: + response = ser.readline().strip().decode() + except UnicodeDecodeError as e: + print(f"Decode error on attempt {retry_counter + 1}/{retry_limit}: {e}") + time.sleep(0.1) # Add delay between retries + response = None
113-122: LGTM! Good implementation of flexible baud rate handling.The changes improve hardware detection by:
- Making baudrate parameter optional
- Implementing fallback logic as documented
- Providing clear progress messages
334-334: LGTM! Consistent with flexible baud rate handling.The removal of the default value aligns with the new implementation in detect_hardware.
… positive frequency components, reducing computation time and memory usage for real-time EEG processing.
