Hi all,

I am looking for a circuit or IC that I can convert a digital SPI 1-wire signal so I can control an analog RGBW LED strip.

I am putting LED strips in my 3D printer enclosure controlled by a Raspberry Pi 4 and I have a couple of rolls of analog 24v RGBW strips that I would like to use.

I am using the "RGB status" plugin on Octoprint found Here but it is only set up for Digital WS2811, WS2812 and SK6812 LED strips. I don't need individually addressed pixels, I just want solid colours like Red, Green, Blue, Amber and White. SK6812 has the extra channel for the White LED whereas the WS series only do RGB.

If I have too I will get the SK6812 strips but as I have the analog strips I would like to use them.

Thanks.
Mike.

 

It will be a lot easier to run WS2812 LEDs as they are already programmed for.
Otherwise, something like an Arduino to decode the signals (and developing the code if it is not readily downloadable), and the Arduino running FETs to drive the LEDs.
