This is an early picture when I didn’t have ribbon cables that were long enough.
It feels like the ribbon cables they give you are designed so that the panels are in a long string side by side, or if they are on top of one another, every other panel underneath must be rotated upside down.
Sure, you an remap all the pixels in software, but even NeoMatrix does not handle panels being upside down, it’s non trivial and generally annoying.
Am I correct in understanding that the SmartMatrix panel layout options are designed to handle how you can chain panels differently and cable in zig-zag, but that all the panels must always face up in the same direction?
If so, am I also correct that basically those too short cables that come with the panels I have (and I now have a stack of them) are all useless unless I chain panels side by side, which I don’t?
Here is a half funny example of what I had to do early on until I received my shipment of longer cables to connect two “too short” cables together:
