<![CDATA[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);

}
