I was wondering if there is a way to set the whole WS2812B Led strip on one color at once with the library from Jgarff?

I know i could use this code:

    while True:
        for i in range(strip.numPixels()):
            strip.setPixelColor(i, (0, 255, 0))
            strip.show()

But i have 864 Led's so it takes the Raspberry Pi 30 seconds to set all the Leds on the given color.

So I searched for a command like strip.fill or something like that and i didnt find anything. So is there a command or a fix for the for loop?

I'm thankfull for any input.

example1

        for i in range(0, strip.numPixels()):
        strip.setPixelColor(i, (0, 255, 0))
        strip.show()

Is the `strip.show()` line part of the loop, or not? We can't tell because you failed to accurately preserve your indentation when pasting the code here. – jasonharper Mar 18 '21 at 17:30
Yeah, sorry the strip.setPixelColor(i, color) and the strip.show() are part of the for loop i forgot the tab. – Sapphire_py Mar 18 '21 at 17:31
Well, get it out of the loop then! That's the exact opposite of the "all at once" behavior you want. – jasonharper Mar 18 '21 at 17:34
How do I do that. Could you please give me a sample. Im new to programming. – Sapphire_py Mar 18 '21 at 18:23
Just unindent that line so it lines up with the `for` statement. – jasonharper Mar 18 '21 at 18:26
Like in the example1 on the question? – Sapphire_py Mar 18 '21 at 18:28
I put the strip.begin now outside the for loop and now it works. – Sapphire_py Mar 18 '21 at 19:01
