Does the neopiel library have support for parallel strips?

Does the neopixel library in arduino IDE have support for paralleling strips? wherein in outputs data at 4 pins at the same time?

Do you want the strips to all do the same thing, or different patterns on the different strips?

Diifferent things actually. For example a 2000pixel long strip divided into 8 channels of 250pixel.

I am attempting to increase the "refresh rate" of the strip as writing the all 2000 pixels in series would take too long.

That is indeed very cool !

Just to confirm, i can use this with my rp2040 based board. Are the associated hardware necessary? because i have already built my own level shifting circuit (did not know you have those)

The library h been updated to support the rp2040. See this page of the guide:

https://learn.adafruit.com/adafruit-neo ... rp2040-use

If you have your own 74AHCT125 or similar level shifting circuit, you do not need the NeoPixL8 board.
