What to drive a led matrix with

JoeGuitar said:

Hi,

I have a bunch (40) of 8x8 lex matrixs that I want to be able to drive, but I don't know what ic(s) to get to do it.

I just used i/o pins on my picaxe to drive one one of these to get it going but now I want to be able to get them all going at once & use them like a marquee.

So, what ic's would be best to get to drive these leds? I'd like to use something current rather than try and source an obsolete part.

I'm kinda new to all of this so keep that in mind.

Thanks for your time.
Joe

How many do you hope to drive at once? All 40 8x8 arrays? What configuration?
