I was an idiot and the data direction was the wrong way. So far the lights are working.Are the pixels definitely hooked up with the right data direction?
Can you log into FPP and under the inputs is "input enabled" ticked?
On the outputs>pixel outputs are all the props showing up and and the "outputs enable" ticked?
In FPP under Status>Display testing can you get any lights happening?
If you get the display testing going in FPP under tools>test in Xlights can you get lights happening
