LED Array

I had to get off the PicBasic List Server! It was killing me!

Anyway, I'm trying to be clever in designing a better or at least clever way to build and drive an Outdoor style LED sign. One using a matrix of superbright LED's to build a sign.

Problem is, I don;t even know how it is normally done. Obviously, you can;t have an I/O line for every element in the array, so It must be matrixed. So if you have a 40 line by 200 column, you have "addresses" like 0,0-40,0 - 0,0-200, etc.

Is a lookup then used to transfer letters into an array of matrix addresses?

Lost in LED's...

There's so many ways of going about this...

Try this as a brief intro to get you started on one method...
