Thank you for you help,

now I solved the problem with esp32_digital_led_lib library.

Example:
[CODE]
#include "esp32_digital_led_lib.h"

// Enumberation ob LED's
// 9 0
// 8 1
// 7 2
// 6 3
// 5 4

#define LED_PORT 15

strand_t m_sLeds = {.rmtChannel = 0, .gpioNum = 15, .ledType = LED_WS2812B_V3, .brightLimit = 32, .numPixels = 10, .pixels = nullptr, ._stateVars = nullptr};

void Led_Init(void) {
pinMode (LED_PORT, OUTPUT);
digitalWrite (LED_PORT, LOW);

if(digitalLeds_initStrands(&m_sLeds, 1)) { E_TRACE("Can't init LED driver()\n"); } digitalLeds_resetPixels(&m_sLeds); // Set led 7 to red m_sLeds.pixels[7] = pixelFromRGBW(55, 0, 0, 0); digitalLeds_updatePixels(&m_sLeds);

}
