WS2801 uses a SPI-like two-wire protocol with clock and data. Although some datasheets mention maximum clock speeds of 2MHz or even 25MHz most LED strips only work reliably up to 1MHz so use that to stay on the safe side. The data frame is 24 bit R, G, B (in this order) per LED, a pause of 500us resets the LED index. Signed-off-by: Matthias Reichl <hias@horus.com>
