Linux phones have IMU units. Allow applications to use them same
way they would access IMU on esp32 based devices. Lightly tested
on PinePhone.
Same applications useful on esp32 (compass, step counter) are likely
to be useful on Linux phones, too.
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.
