Do you have a microcontroller in mind that would work? Is this a hardware PWM or software PWM? Yes i understand PWM that's why i chose PWM as a control standard for RGB L.E.D. Control. 24 outputs from 1 chip seems like an awfull lot, but if you have a chip in mind i'm ready to listen. Maybe i need to clarify my lighting, i need 24 outputs for 8 modules with 3 leds each, 1 red, 1 green & 1 blue. I want all 8 molues to be able to change to any color at any time by computer control. Thanks, Kevin
