Arduino Due and 60 LED/meter strip

Does the new #1138 60-LED/meter LED strip work OK with the Due's timing abilitgy and 3.3V signals? (I'm sure there's enough RAM available.)

I'm currently using the 32 LED/meter strip with the Due, and it works fine. I'd like to use the new strip if the conversion isn't too difficult and it is compatible.

The 3.3V part is fine (for the data line, but still want to power the strip with 5V). But there's no code yet written for the Due. Those LEDs require super-precise timing (the ATmega code is mostly inline assembly with interrupts disabled) and will require a complete do-over for the Due's ARM core.

Thanks for the quick reply. Things are working with the other strip, so can wait.

Have you considered putting out a simple shield that would buffer and strobe the strip? Makes it board-independent.
