thank you very much!i am designing LED lamp,every lamp consist of three color LEDs(red,green and blue).it means that every lamp must engross 3 channel address,it can only control 170 lamps,

channel 1=lamp1 red brightness
channel 2=lamp1 green brightness
channel 3=lamp1 blue brightness
channel 4=lamp2 red brightness
channel 5=lamp2 green brightness
channel 6=lamp2 blue brightness

and so on.how do u think about this?
