i have a problem addressing an 1m rgb strip using an Arduino Duemilanove.
I followed the rgb strip tutorial on this site ( http://www.ladyada.net/products/rgbledstrip/
) using 3 PWM Pins (1 for each channel) with 3 N-channel MOSFETs (STP16NF06) and an exteral 12V Power supply.
I'm using the Firmata firmware and the maxuino max4live patch to speak to the arduino. Basically addressing the strip works fine, but just one pwm pin at the same time. If i'm addressing two or three pwm pins simultaneous the output begins to stutter and is clearly delayed. It seems like the arduino can't handle all the pwm data at the same time. I've already done some research but just can't figure out exactly where's the weak point.
I would be very very thankful to get some tips!!
