what arduino are you using and how is this powered ?

I'd suggest you first test the strip without things being too complicated

run this:

#include <Adafruit_NeoPixel.h>
const byte dataPin =  3;      //Data pin
const uint16_t nbPixels = 256 ; // 32x8
Adafruit_NeoPixel strip = Adafruit_NeoPixel(nbPixels, dataPin, NEO_GRB + NEO_KHZ800);

const uint32_t tempo = 100;

void setup()
{
  strip.begin();
}

void loop() {

  for (uint16_t i = 0; i < nbPixels; i++) {
    strip.setPixelColor(i, strip.Color(128, 0, 0));
    strip.show(); // This sends the updated pixel color to the hardware.
    delay(tempo);

    strip.setPixelColor(i, strip.Color(0, 128, 0));
    strip.show(); // This sends the updated pixel color to the hardware.
    delay(tempo);

    strip.setPixelColor(i, strip.Color(0, 0, 128));
    strip.show(); // This sends the updated pixel color to the hardware.
    delay(tempo);

    strip.clear();
  }
}

you should see all pixels lighting up one after the other in 3 primary colors. (modify tempo if it's going too fast for each color)
