ClearFlags

enum class ClearFlags : fl::u32

strong

Flags for FastLED.clear() to control what state gets cleared/reset.

These flags can be combined using bitwise OR (|) to clear multiple settings at once. Each flag controls a different aspect of FastLED's global state.

// Clear only channels
FastLED.clear(ClearFlags::CHANNELS);
 
// Clear power settings and brightness
FastLED.clear(ClearFlags::POWER_SETTINGS | ClearFlags::BRIGHTNESS);
 
// Clear everything
FastLED.clear(ClearFlags::CHANNELS | ClearFlags::POWER_SETTINGS |
              ClearFlags::BRIGHTNESS | ClearFlags::REFRESH_RATE |
              ClearFlags::FPS_COUNTER | ClearFlags::CHANNEL_ENGINES);
