    • M5Stack Faces II Led drive

      Hello,
      I use the Adafruit_NeoPixel for drive the 10 Leds (2x5) in my Faces II base
      After the begin(), show() functions, all leds are off, but when I want to change a pixels and make a show() the first LED stay on event I put all pixels(index) to 0
      Any know this worry ?
      My code is this

      #include <Adafruit_NeoPixel.h>
      #define M5STACK_FIRE_NEO_NUM_LEDS 10
      #define M5STACK_FIRE_NEO_DATA_PIN 15
      Adafruit_NeoPixel pixels = Adafruit_NeoPixel(M5STACK_FIRE_NEO_NUM_LEDS, M5STACK_FIRE_NEO_DATA_PIN, NEO_GRB + NEO_KHZ800);
      vois setup() {
      pixels.begin();
      pixels.show();
      }

      void setPixels(int r, int g, int b) {
      for(int i=0; i<10; i++) pixels.setPixelColor(i, pixels.Color(r, g, b));
      pixels.show();
      }

      void loop() {
      setPixels(0, 100, 0);
      delay(500);
      setPixels(0, 100, 0);
      delay(500);
      setPixels(0, 100, 0);
      delay(500);

      }
