showPixels()

template<typename CONTROLLER, EOrder RGB_ORDER = GRB>

virtual void RGBWEmulatedController< CONTROLLER, RGB_ORDER >::showPixels ( PixelController< RGB_ORDER, LANES, MASK > & pixels )

inlineoverridevirtual

Main rendering function that converts RGB to RGBW and shows pixels.

This function:

1. Converts each RGB pixel to RGBW format based on the configured conversion mode
2. Packs the RGBW data into a format the RGB controller can transmit
3. Temporarily bypasses color correction/temperature on the base controller
4. Sends the packed data to the physical LED strip

   Parameters

   pixels

   The pixel controller containing RGB data to be converted

Implements CPixelLEDController< GRB, CONTROLLER::LANES_VALUE, CONTROLLER::MASK_VALUE >.
