Does this work with WS2812b? #3

wdebusschere commented 1 month ago

We tried to use the library with a Raspberry pi 5, GPIO 10 and WS2812b with external power, but only 1 or 2 leds light up.. Has this been tested with WS2812b? Thank you.

Yes ! the led it has been tested with is this

Also see here

Have you connected the ground (from raspi) to the led too ? , it is needed for data transfer to work correctly almost everywhere , if you havent , try shorting the ground of your external power supply , and raspi and led

DONT SHORT THE +VE SHORT THE -VE

@vanshksingh Connecting the ground to the raspberry did the trick! Thankyou.
