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.
