B4R Library rAdafruitRGBMatrix with WS2812

You will need to do some research. rAdafruitRGB wraps this project: https://github.com/adafruit/RGB-matrix-Panel

I think you will need to write your own text-to-dot-matrix code, as WS2812 are meant to be controlled individually.

I remember having requested EREL, who gently provided, for a way to convert integer values into a 2 dimention array, thus being able to coorespond a single LED into a matrix value…

Thanks for the advise.
i used GFX, NeoMatrix and NeoPixel Libaries from Adafruit in my last own opensource Project (https://github.com/awtrix/awtrix).
Want to convert this to B4R. So as i see i have to learn how to wrap this libs
