I actually did it in kind of a screwy way. I had I think 8 data lines and 3 or 4 select lines, so I put D flip-flops on the first three select line output 'addresses', and wrote the red, green and blue color data for a specific row out to them. This allowed me to have 24 data outputs, so I could light 3 color channels for each of the lights in the row. After I programmed this column data, I used a different select line 'address' to turn that row on so it could be displayed.

whats all the logic we see at the end?
I recently have finished a school project which used an old basic stamp to drive five 5x7 LED arrays.
would I be right in thinking you used 74-137/138 (or cmos equiv. - either way I used 3 bit BCD line decoders) pairs to drive the LED's with?
