All frameworks now follow the same singleton class pattern with class methods:
AudioFlinger (already had this pattern)
DownloadManager (refactored)
ConnectivityManager (refactored)
CameraManager (refactored)
SensorManager (refactored)
Pattern Structure:
class FrameworkName:
_initialized = False
_instance_data = {}
@classmethod
def init(cls, *args, **kwargs):
"""Initialize the framework"""
cls._initialized = True
# initialization logic
@classmethod
def is_available(cls):
"""Check if framework is available"""
return cls._initialized
@classmethod
def method_name(cls, *args):
"""Framework methods as class methods"""
# implementation
2. Standardized Imports in __init__.py
All frameworks are now imported consistently as classes:
from .content.package_manager import PackageManager
from .config import SharedPreferences
from .net.connectivity_manager import ConnectivityManager
from .net.wifi_service import WifiService
from .audio.audioflinger import AudioFlinger
from .net.download_manager import DownloadManager
from .task_manager import TaskManager
from .camera_manager import CameraManager
from .sensor_manager import SensorManager
3. Updated Board Initialization Files
Fixed imports in all board files to use the new class-based pattern:
linux.py
fri3d_2024.py
fri3d_2026.py
waveshare_esp32_s3_touch_lcd_2.py
4. Updated UI Components
Fixed topmenu.py to import SensorManager as a class instead of a module.
5. Benefits of This Harmonization
✅ Consistency: All frameworks follow the same pattern - no more mixing of module imports and class imports ✅ Simplicity: Single, clear way to use frameworks - always as classes with class methods ✅ Functionality: All frameworks work identically - init(), is_available(), and other methods are consistent ✅ Maintainability: New developers see one pattern to follow across all frameworks ✅ No Breaking Changes: Apps continue to work without modification (Quasi apps, Lightning Piggy, etc.)
6. Testing
All tests pass successfully, confirming:
Framework initialization works correctly
Board hardware detection functions properly
UI components render without errors
No regressions in existing functionality
The harmonization is complete and production-ready. All frameworks now provide a unified, predictable interface that's easy to understand and extend.
