SP201E to WS2812 LED strips DMX control

SP201E DMX Decoder running WS2812 LED Strips and being controlled by DMX.
Each WS2812 is assigned 3 DMX channels, Red, Green and Blue. This works out to an odd number and makes programming scenes a bit difficult. Normal DMX lights are 4 channels, red, green, blue and white. Also this DMX controller does not have a master brightness control.
