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.adafruit_support_bill wrote:Do you want the strips to all do the same thing, or different patterns on the different strips?
I am attempting to increase the "refresh rate" of the strip as writing the all 2000 pixels in series would take too long.

For best performance with multiple strips, there is the Neipixl8 library and associated hardware: https://learn.adafruit.com/adafruit-neo ... nd-library

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)

Re: Does the neopiel library have support for parallel strip
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.
