Ok,
Maybe this story will help others someday.
I was testing out 6 square SS modules (3x5050 each) ... and having no luck controlling them from the SSC.
Nopte: These 6 SS squares are part of single RGB "megaball". Obviously there will be multiple megaballs on the same SSC
eventually, but just testing one of the six packs for now.
So after much un-successful testing/troubleshooting, I decide to try hooking up just a couple of different square modules
instead and trying that.
So I hooked them up, programmed the SSC to 8 node of square SS modules ... then tried just running the 2-only. And they worked fine!
So then I hooked (daisy chained) up the other 6 modules after the first 2 modules ... since I was using the SS 3-core quick connects, so I then had 8 modules hooked up ...
and again, they all worked great. wow!
So then I went back to just using the 6 modules ... directly connected to the SSC ... and again, they did not work! argh.
So I go back to the 2, they work. Go back to the 2 connected to the 6, or 8 ... they work.
So It appears I have at least one Square module (the first module in a 6 module group/string), which doesn't want to work
when it is the first node after the SSC.
But when I put that module after a couple of other (after my 2 string group/string) ... it works fine. The wire distances are all very short,
so I don't think thats the issue.
So I'm kind of thinking this could be a defect in the module, because last night it made me think all the modules were, dead, but in fact ...
they all work fine, but this leading module is the problem and doesn't want to be the first after the SSC for some reason.
Comments appreciated.
