WS2812 Breakout Clock Connection?

Community Projects

The https://github.com/sparkfun/WS2812_Brea … xample.ino for the WS2812, the connection instructions refer to SDI and CKI, which I assume are data and clock connections. The Sparkfun breakout only has a Data In connection. Will the code work without a clock connection? Or am I missing something?

Thanks,

Don

I would follow the hookup guide (https://learn.sparkfun.com/tutorials/ws … okup-guide) and use the Adafruit Neopixel library instead. That code appears to be for WS2801, not WS2812.

Are similar devices the basis for the new outdoor “TV screen” billboards?

[https://www.sparkfun.com/products/12584](https://www.sparkfun.com/products/12584) are the type of devices typically used in large video displays. The WS2812 protocol is too slow when used in large quantities.

Thanks, darrellg. I think you’re right about the Github library. I hadn’t finished reading the Sparkfun hookup guide, so I didn’t see the Adafruit reference.
