Rainbow example doesn't properly set the first pixel with Arduino 1.8.2/Teensyduino 1.36 #17

Arduino 1.6.12 and Teensyduino 1.31 is the latest combination that works for this demo for me.

Yup, looks like a bug was recently added which affects some (but not all) LED strips.

I will look into this within the next few weeks.

+1 on this. What I find is that everything is off-by-one; setPixel(n, color) lights pixel n+1. Happy to look into it if you have any guesses / hints where it might be?

Just ran into this issue as well!

I've uploaded a new version with OctoWS2811 fixes. Please give it a try and let me know if it solves this problem on your LED strips.

It looks like that fixes it. Can a second party confirm this?

PaulStoffregen commented 7 years ago

Yes, several people have confirmed on the forum.

I'm closing this old issue.
