Sk6812-Rgbw RPi2 #292

Closed Soupofdoom closed 6 years ago

Soupofdoom commented 6 years ago

I'm trying to run a SK6812RGBW strip (30/m x 1m) from a RPi2 B+ and no matter what I try when I output to the LEDs I get the pattern red, green, blue and off across the strip when attempting a singular color wipe to blue. The pattern shifts along when I try to wipe to a different color.

I looked at penfold42's branch from a while back (and even tried that) but nothing helped.

I changed the strip type in the config and disabled audio PWM and forced HD I audio.

LED_STRIP = ws.SK6812_STRIP_RGBW

I'm guessing that this is a timing issue and/or I'm just missing something essential/being retarded.

Can anyone help?

What if you set the strip type to ws2812 ?

I wonder if they sent you an sk6812RGB (no white) strip

So I haven't seen it myself (I'm at work) but I talked the wife through testing this and it does seem that this is the case.

Ill update later to confirm.

Okay, so just got home and this is indeed the case! Thanks for the suggestion @penfold42!

Time to get complaining to that company!

Don’t let them whitewash the issue
