Hello picsters!

I want to tinker with an 8 x 5 led matrix...

and I want to use a master to serially send out two bytes, the first being a
reference number for each matrix, followed by a second number
to turn on or off each dot in the matrix...


and my solution so far has been to use a 16F876 to set up one pin
to listen for a reference number, then use the next number to turn on the
dots...



well, there's got to be a cheaper way to do this... with the cost of the pic
and
the dot matrix together....the entire thing gets to be quite pricey....even
the cost
of just the dot matrices sort of makes me shudder....

anybody have a more elegant, less costly, probably obvious except to me--
solution?

thanks.

also, I was planning on making or having a little piggyback circuit board
produced
for each matrix, so that they would in effect become modules, so, well
nothing I
guess, that's just what I was thinking....
