Hello i want to light up an led strip with 300 neopixels the problem ist that it takes about 10 seconds untill all oft the led are lid because the animation i want that all led lid at the same time so it takes no time

Hi @LostiLama you will have to provide more info. What node-red contrib nodes are you using? can you share your flow (CTRL+E to export)

NOTE: it is important to surround your code with three backticks  
`````  
`like this`  
`````

See this post for more details - [How to share code or flow json](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506)

Hi, in order to make code more readable and importable it is important to surround your code with three backticks  
`````  
`like this`  
`````

You can edit and correct your post by clicking the pencil icon.

See this post for more details - [How to share code or flow json](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506)

Also, you did not answer question...

what happens if you simply inject a colour into the neopixel node?

Then the same happens only if i use 1,0,255,0 in this case lid led 1

but what if you inject `0,255,0` (just the RGB without the leading `1`) - what happens?

how many pixels are there?

what happens if you inject `100,255,0,0`?  
what happens if you inject `200,255,0,0`?  
what happens if you inject `1000,255,0,0`?

connect the function to the neopixel node & press the injects - does that work?

without the library supporting such a feature, we have to work around its capabilities by generating the 300 pixel messages.

There may be a payload format that supports setting all - but i have no access to a device to try it out.

if you want you can look in the code if there is any stuff for that

the nodes built in helps says...

> A range of pixels from _x_ to _y_ can be set by `msg.payload` with a CSV string _x,y,r,g,b_

what happens if you inject `0,299,0,0,255` directly into the neopixel node?
