Hi Guys,
Thanks for your comments. Fixed the issue. It was a bad data connection on an extension and got the pixel lengths muddled up in 12s configurator. Now that I got the string lengths correctly configured all is running great!
Anyone know if you can join and address WS2811 Pixel strings? Got some DC5V 40 Node pixel light strings, but having problems addressing extended/joined strings with a 12s. Have tried joining the strings to extend beyond 40 pixels/nodes but only an initial few nodes light up. Also get strange...
