using RGB LED on WEMOS/LOLIN S3 mini

[c64emulator]

I want to see status of a running sketch on a WEMOS/LOLIN S3 mini https://www.wemos.cc/en/latest/s3/s3_mini.html.
This device has a RGB LED on IO47. According to the schematics it is a WS2812B-0807.
How can I control this single pixel LED with your lib?
I am thinking about a single task running on core1 feedable with some parameters (on/off, color, doBlink, doBreath).
Can you PLS provide some example?
Any other idea?

Did you try the "NeoPixelTest" example from the library?
Just change the pin number in the sketch to the pin that is used for your board.

No, I did not try any example (but investigated all), because I have only one pixel to show. The e.g. "NeoPixelTest" states:

const uint16_t PixelCount = 4; // this example assumes 4 pixels, making it smaller will cause a failure

It's an example, you can modify the code to support less.
Also, while the bus driver will output a signal for 4 pixels, if you physically only have one it will still work for that one pixel.

Note that this library wraps up the complexity of driving the LEDs. It has helper classes to make it easier for the sketch author do more advanced things, but it doesn't just a function you can call to "blink". You have to write that. Review the examples. Review the examples for my Task Library, which implements LED flashing for single color LEDs but could be easily modified to call NeoPixelBus.
