KC868-A8S_WS2812-RGB_LED

[garrip]

I am trying to use this example code

[Arduino IDE demo source code for KC868-A8S]--#08-KC868-A8S_WS2812-RGB_LED_code

but WS2812 is alway off.
PIN 12 is LOW.

I'm wrong, but I can not understand why.

I  test output, input (digital and analog), GSM, and RF433 using my code, everything works fine.

I can't get it to work (tried different code and library) is the RBG WS2812 led on the board only.

I tested my code on RBG WS2812 ring using a ESP32-Wrover-E and it works.

Can someone help me,  please?

Can someone tell me how I can download a demo firmware, when I turn on the board  the first time,  the led changed color.
I want to test the RBG WS2812 LED, so if I have broken it, I'll change with a new one.

Thank, best regards.

Hello!
I'm testing the RGBW LED on the KC868-A8S board, using the code:

Code:

light:
  - platform: neopixelbus
    type: RGBW
    variant: ws2812x
    pin: 12
    num_leds: 1
    name: "NeoPixel Light"

but when I choose a color, it doesn't turn on the chosen color, for example, if I choose the color red, the LED turns green.

Do I have to do some kind of calibration or use another code?

take a photo how you wire.

I'm using the LED from the KC868-A8S board itself:

"RGB LED WS2812.  If not have display, then at least a multi-color LED, which can also notify about various events and states of the system."
