Hi,

Is this currently working? I'm trying to drive a single WS2811s (in particular this circuit: https://hackaday.io/project/4603-pixiflood).

I've tried using the hardware SPI implementation on the ESP8266 too but I've had no joy with that either. The LED works fine on my Espruino Pico using hardware SPI so I know that's fine.

My environment is:
NodeMCU
Espruino v81.780
12V circuit running the LED, 3.3V in the NodeMCU, common ground

Here's the code I've been using:
```
var esp = require("ESP8266");
var pin = new Pin(15);        // I've tried all available GPIOs
esp.neopixelWrite(pin, [50, 50, 50]);
```
Any help would be really appreciated as I'd like to use this for a demo of some of my research on Wednesday.

Thanks!

Try the following:

var esp = require("ESP8266");
var pin = new Pin(15);        // I've tried all available GPIOs
pinMode(pin, "output");
esp.neopixelWrite(pin, [50, 50, 50]);

It may be that setting the pinMode explicitly to output is required.
