brightness issue

[faryar76]

hi👋
rgb(1,1,1)
in python makes a very low brightness white
but in javascript output is very bright (90 is darker than 1 !)

in my case output is not compareable

any idea?

I thought I was the only one with this problem! Yeah, the brightness of everything is way off.

I tested other LEDs, and I think I know the problem: the bits sent to the WS2812 are mirrored:
When I send brightness values like this: 128, 64, 32, 16, 8, 4, 2, 1 then the brightness goes from very dim to quite bright.
0 and 255 and dark (off) and very bright..
I'm not (yet) sure how this can be fixed since I don't yet understand how the PIO exactly works...

I think I solved this problem. See my pull request.
