Hi everyone,
As the title says I am trying to use Arduino to control some ucs5903 led drivers. The info about these chips is almost nothing. The most useful thing I found is that they are very similar to d705. The first link if you google d705 is the datasheet. Using the shiftout function of the arduino I managed to get the 3 basic colors: red, blue, green using this code in the attachment. I managed to get similar results with the hardware SPI too. The main problem is that I don't understand how to get other colors (except using shiftOut(PIN_DATA, PIN_CLOCK, MSBFIRST, random(0,255)

and how to get dimmed colors. The final project is to create an ambilight using 25 of these controllers. The software I will try to use is lightpack prismatik.
Thank you,
Alex
