Please help me chaps, I had this all figured out now somehow I've messed it up.
I'm using the Arduino to program my 8x8 matrix, to start off with it's just one layer. I managed to get it working successfully, and program a diagonal scroll in there.
However, I've built all 8 layers now, and yet I'm having no luck trying to hook it up again. I know it works because I had the same problem before and fixed it, though I didn't take any pics - my biggest regret.
So if you wouldn't mind taking a look at my set up to see if there's something obvious I've missed out. I'm sure a second brain will point out my mistake, and everything will be good again. I'm losing sleep over this.
Oh, the rows/columns are unplugged to give you a better idea of what's going on. And there is a connection from +5V to the chip, it's just hiding behind that resistor in the second pic
