RC4 available, fixes WS2812B bug
Dan and I are happy to announce immediate availability of FastLED (aka FastSPI_LED2) v2 RC4 library from
https://code.google.com/p/fastspi/downloads/list

This release fixes bugs with WS2812B LED strips, and a bug with passing colors as 'long’s. (Whew.) Dan peered deeply into the low level timing and it should be rock solid now, on both AVR and ARM. In addition, this release fixes timing problems with Arduino Mega pins.

Please download and test this release, particularly if you use WS2812B strips… If there are no new ‘blocker bugs’, this will become “2.0”. Have at it!

fantastic! i’ve already downloaded installed and tested with my flickering lights (WS2812B strips afaict - 4 connections to the LEDS & sourced from ray wu) and this has fixed ALL the problems with flickering. not quite tested everything yet but all good so far, cheers!

Thanks for the field report, and glad to hear it!

Same here, the 2811s that I found out are actually 2812B no longer flicker, and setting the entire strips color at once works marvelously.

Yep, downloaded and compiled into Studio. RC4 appears much more ‘stable’ (pun intended). For my current application it is working perfectly.
Thanks for the effort in doing the update.
