The shield uses digital pin 6 to communicate and Neopixels are not happy sharing interrupts so be aware of that when using mixed code. It also does not work well on OSes that are preemptive like Linux due to the tight communications requirements. Check with the pcduino folks to see what they think.

Yep, linux based developed systems have some problems with ws2812's... but they said, a seril link could do the works. Could you suggest an arduino system? i need a mp3 player+neopixels shield to do a digital spectrum (like media player) the thing is manipulate the matrix and play the songs at the same time ;F...

Maybe with raspberry ?
