The WS2801 requires 3 separate resistors to set the current. If I wanted to use one of these chips to drive an RGB LED strip, I would take the 3 outputs of the chip and use it to drive 3 MOSFET's. Since the strips are already current limited, do I still need to use the resistors ?
In regards to the WS2803, to use this chip with RGB strips I would do the same as above, however, does it make much difference which pins go to which color ? ie. If I had 6 RGB LED's could I take all the Red lines and run them to OUT1-OUT6, the Blue to OUT7-OUT12, and the Green to OUT13-OUT18 or do the have to be RGB, RGB, RGB, etc. ?
