Hi all,
I have a 100 RGB LED strip that uses the WS2801 IC. I also have 40 white 1.8V LEDs that I'd like to control. Would it be possible to piggyback these at the end of the strip with 3 LEDs per additional WS2801s? So, if pixels[0..99] were my RGB LEDs, pixels[100][R.] would be the white LED #1, [100][G.] = LED #2, [100][B.] = #3, [101][R.] = #4, [101][G.] = #5, etc.
I have been investigating using another shift-register chip like MAX7219/21 or the 74HC595, but thought this might be an easier solution.
Any thoughts?
Thanks!
Alan
