I've found that dereferencing a NULL pointer will reset my code. I found this out by accident and didn't want it :-(

Thanks for that. That must have taken a while to write.
Very comprehensive. I like the idea of using IDE cables, I have quite a few of them knocking about.

I'm using an Mega. Would it be possible with this library to drive multiple displays? I'm using the displays just for text.

No. The chip won't work the way you want. You'd be better off following this tutorial if you want to save pins:

You can keep adding more 595 chips without using any more Arduino pins.

@gardner

I'd be interested in seeing your protocol and code.

Why not just wire two ULN2003 in parallel. That way you can run 1000mA per strip.

If you're looking for full duplex RS422 you could try using a DS8921
