Hi the actual datasheet is: http://www.szledcolor.com/download/SK6812%20LED.pdf
you have to send 24bits (3x8bits for the Green:Red:Blue Leds) and if you casade the Led/IC then you have to send n*24bits where n is the number of led/ics that you have The data is serial asynchronous and the structure of the pulses are in the data sheet Regards
