Today I took delivery of my order from Ray, one of the items was, LED digital module,WS2811IC 5050 3LEDSC12V input,waterproof,20pcs a string;256 gray scale . This is the exact same thing I ordered last year. I am in the process of rebuilding my candy canes with these pixels as the are brighter, I also thought I would add a couple of canes too. In the process I fried a couple of pixels, so needed to replace them. I took the new ones and placed them in the cane they ended up being the first three, with 5 more of the old ones placed after in the string. The old ones didn't work, I fiddled and stuffed about, found that the old 5 pixels were all still good, so I pretty much just made the last cane with 8 new pixels. But, first they are the wrong white, more a warm white than a bright white of the other, now that's not a big issue, in the dark I am sure only I will notice (and pull out just one hair each time), but the odd issue is this. The new pixels will accept data from the old, and work. But the will not send data to the old. If the new pixel can is at the end of the string, it works fine, place it at the start, or in any place it has to send the data on, every thing works until the last pixel in the new cane. Ideas anybody?
