Control first LED on neopixel strip with FastLED with M5Stack

Kees

Some simple questions:

Controlling the LEDs works well, but how can I control the first LED? Most of the time it is a very bright white, but it can change.
How can I use the strip on a M5Stick C?

On Arduino using the M5Stack (in my case the Gray version) pin 21 is the pin to pass on to FastLed. For M5StickC it is pin 32.
That the M5Stack shows a bright white light for the first LED seems to occur when one also uses the M5.Power.begin() command.
This piece of code should work on both devices adjusted for the device in use:

//#include <M5StickC.h>
#include <M5Stack.h>
#include "FastLED.h"

CRGB leds[15];

void setup() 
{
M5.begin();
    FastLED.addLeds<NEOPIXEL, 21>(leds, 15); // M5Stack Gray
    //FastLED.addLeds<NEOPIXEL, 32>(leds, 15); // M5StickC 
}

void loop()
{
    static uint8_t hue = 0;
    if (255 == hue)
        hue = 0;
    else
        FastLED.showColor(CHSV(hue++, 255, 50));
    delay(50);
}
