ws2813 strip led with raspberry

Tue Mar 05, 2019 7:09 am

Good morning,
I started few days ago to program raspberry and I would like to control the ws2813 strip led with raspberry as I' ve already done with arduino and fastled library. I tried to find some informations and tutorials online, but I did not find anything. I would like to ask suggestions and help to someone in order to control the ws2813 strip led in raspberry with fastled library or something similar.
Thank you very much in advance
Best regards

Have a look at this library https://github.com/jgarff/rpi_ws281x

My understanding of this chip is that it will need a level sifter unlike the ‘2812’ and due to the faster data rate you need a reasonably new Pi that’s not doing much else :!:

AFAIK Any WS2812 raspberry pi tutorial will work the same with the new WS2813 strips
Just google for raspberry pi ws2812

Just seen @AndyRoo post - I'd try a WS2812 tutorial - see what happens - then come back and tell us if it worked

Hello,
i have a problem with the ws2813 aswell. I connected GPIO PIN 18 to the DO of the led stripe and power aswell.

With the arduino(fastled library) of a friend of mine it works just fine.
But i want to use a raspberry pi.
So i installed rpi_ws281x library on it and run some test script.

Sadly just every 2nd led is working.

Does anybody have/had the same problem?

Tyvm,
