-/** WS2801 class, controlling LED strips or arrays like this http://www.sparkfun.com/products/10312
-*
-* the WS2801 IC's are 5V but works well connected directly to mbed IO pins.
-*
-* You need a 5V power supply capable of about 2A to light up a 32 led strip, do NOT power from mbed(usb).
-*
-* the required reset delay is a blocking wait(), it can be lowered (or set to 0) if you want to use the
-* time for executing code instead, data sheet says 500us but i found it need at least 800us.
-*
-* Example:
-* @code
-#include "mbed.h"
-#include "ws2801.h"
-
-#define STRIP_LENGTH 32
-
-ws2801 mystrip(p9, p10, STRIP_LENGTH);
