I've just bought some rigid 2812B bars from Ray Wu - http://www.aliexpress.com/item/1m-DC5V-WS2812B-LED-rigid-bar-32pixels-m-with-transparent-cover/1827806734.html but I'm having trouble getting any output from my P12S. I've updated to the latest firmware but in the string config there is no 2812 config just 2811. I've also seen on another post that 2812B can be run just with data and gnd outputs from the top board of the ECGP12S but I'd prefer to run power to the strips via the P12. I've used the 5v+, data and gnd outputs from the P12 directly to the strip but can't get anything on the strip. I've tried a few different speeds 1000 and 3000 but still no blinky flashy. Any suggestions about configuring the ECG P12S for 2812B would be greatly appreciated.
