SK6812 LED (NeoPixel)

[Ugly-Wan]

I have successfully flashed this product: https://www.amazon.com/Gevcc-Changing-Corner-Google-Assistant/dp/B09Y1NSVNQ?th=1 https://manuals.plus/kyinflose/dfqy-cs14-corner-floor-lamp-manual

I have the buttons and the IR reviver working. The microphones I have set to ADC via the ADC pin but I don't seem to see any info in the logs to reflect the data is being picked up - anyway the mic is less of an issue.

It seems that the LED's are based on this https://cdn-shop.adafruit.com/product-files/1138/SK6812+LED+datasheet+.pdf

There is no additional IC and they appear to be driven directly from the BK7231N via P16.

Do you have any experience with a similar devices?

Any help would be excellent thank you.

I have T based devices with 'music' input. Apparently these don't have hardware FFT (according to beken rep in tiawan). I'm interested in looking at the mic input - but there are more important hings at the moment :(. It's a TV backlight, and my LEDs are PWM driven, br, Simon

Good to know that the mic input doesn't work, I will ignore that that completely for now.

Related: https://github.com/openshwprojects/OpenBK7231T_App/issues/497 Once 497 is solved (ramfunc? any more progress @valeklubomir ? I myself didn't look into it more yet), we could add a simple drivers for all that addressable lights relatively easily.
