arduino-rgb-pixels - issue #1

Flicker/data errors on long pixel chains


Posted on Sep 22, 2010 by Happy Wombat

What steps will reproduce the problem? 1. Try to run the code with 100+ LPD6803 pixels 2. Play with the first parameter in LP.initialize(); 3. Try a simple fade up/fade down green channel as a test effect

What is the expected output? What do you see instead? I would expect all pixels to fade up/down in unison. Instead, after a certain point in the strip, it seems to have errors and flicker (mostly white flicker).

What version of the product are you using? On what operating system? Latest library at time of writing. Arduino 0018, on a Duemilanove Arduino.

Please provide any additional information below. Would really help with large scale installations/purchases.

Another user reports the same issues: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1286992845/1

Better support for this hardware would be nice.

Fixed. Now supports strings of LEDs that are up to 65536 LEDs long.

Status: Fixed
