Ambient Light

[neophob]

sort of ambient light, use the average color of the panel as colour. all panels have ONE ambient colour - it doesn't matter how much panels are used - there is only one ambient color.
there is no need for another controller, the same controller should be used to control the ambient light using 3 analog output signals.
pixelcontroller sends the additional data as 24bit value to the controller. the additional 3 byte value should be part of the regular data transfer.
"dumb" led modules are used for the ambient light (4 wires, RGB + GND)
