RTL8720D and Neopixel

I have RTL8720D and I tried to use some Neopixel with it. Neopixel is WS2812 and I connected it to pin 10. This is the sketch:

#include <Adafruit_NeoPixel.h>
#define PIN 10
Adafruit_NeoPixel strip = Adafruit_NeoPixel(1, PIN, NEO_GRB + NEO_KHZ800);
void setup() {
  strip.show(); // Initialize all pixels to 'off'
void loop() {
  colorWipe(strip.Color(0, 255, 0), 1000); // Green
  //colorWipe(strip.Color(255, 0, 0), 1000); // Green
  //colorWipe(strip.Color(0, 0, 255), 1000); // Green
  colorWipe(strip.Color(0, 0, 0), 1000); // white

// Fill the dots one after the other with a color
void colorWipe(uint32_t c, uint8_t wait) {
  for(uint16_t i=0; i<strip.numPixels(); i++) {
      strip.setPixelColor(i, c);

With this setup, my Neopixel does not work. What am I doing wrong? I use Arduino IDE. I can blink regular LED on that pin. What could be wrong with Neopixel? Should I use some other pin?

Dear @dekip,
Thanks for your question. Currently, the Ameba Arduino SDK (which includes RTL8720DN) is not supporting WS2812 yet. Alternatively, you may proceed to our Github and requesting for this feature. :partying_face:

NeoPixel support has been added, check here for more information,

Has anyone had succes with this? I get errors when compiling

Hi @Olivier_Demoustier, may I know which board are you using and what compilation errors you have gotten? Thank you.
