To recap the WHOLE story from DAY ONE - just so things are clear for anyone who may be reading this and not sure what is going on.

=-=-=-=-=-=

I had Jessie (or Stretch - which ever is just before Buster) running on a RasPi 3B+ and the LED strip was working.

One day during an update power was lost and the SD card wouldn't boot. It was NOT corrupted as in kaput. Just the update was interrupted at a critical time. (Moving on)

I wanted to get that machine back up and working.

NEW (out of the box) SD card. Installed BUSTER, and the other stuff. (Not NR at this point)  
Got it working/booting.

Installed NR to a very recent version.

Did that `curl` command to get/install the `pimoroni` stuff - remembering a long time ago when I made the same mistake and was prompted to check I had installed ALL the requirements. (That stuck with me) 😉

Copied the flow stuff from the old card.

```auto
cd .node-red
npm -install

```

Got all the nodes installed as required.

Started Node-Red.  
Flows running.

NO LED functionality.

$hit!

Walked away.

Months later came back. Tried again. Same: not working.

Dug a hole looking at why. "Get them working from the RasPi point of view".  
Went down that path. Again: nothing useful. Just pointed to the stuff I had already done.

Recently Started digging again.

Decided to install the `neo-pixel` node from the CLI.  
`missing libraries`

Ah! Bingo! That'll be the problem.  
Another 2 weeks messing around trying to find them.  
No luck.

Ran the `pimoroni` script a few dozen more times (confused by the "This command uses sudo" in the _instructions_)  
Anyway: Nothing improved.

During the installation the script was saying that it will force audio out the HDMI port and that patches will be done.  
Then the machine needs to reboot.

Yeah, ok.  
Did that many times as well.

There were mentionings of the two lines _here and there_. But TOGETHER and only implicitly said.  
Not: **You must have these lines in the `config.txt` file, or it won't work**.

Somewhere around this time I dug up two SD cards from other machines.  
One was Jessie, one was Stretch. They both have NR installed. Old-ish version but new enough to test.  
(Both were in a RasPi ZW and had the ribbon camera plugged into them)  
Left them as they were software wise, but plugged them into the other machine with the NeoPixels.

Ran the `pimoroni` script.  
Rebooted.  
Installed the `neo-pixel` node. (With errors)  
Wrote a basic flow to turn on all the LEDs.  
NOTHING.  
Both SD cards.  
This compounded the frustration as there should be no reason anything ELSE would be wrong.

Got ANOTHER sd card with BUSTER from a RasPi 3B+ that has no external hardware.  
Put it in.  
Same. (LEDs not working)

25 Feb 2022  
About 4 days ago, out of _there's nothing else left to do_, I was looking at the old SD card's `config.txt` file and noticed these five lines. Yeah, I got it down to two, but this is the FULL story.

Put them in, rebooted.

The LEDs work.

Out of interest I tried installing the `neo-pixel` node again - why not?  
Again got the error about the missing libraries.

Weird. Not blaming anyone. But _what the....?_

@dceejay Thanks. I appreciate what you did. Others may waste a lot of time if they install the node from the CLI and see that error - as I did.
