OK, I want to have control over every dot, instead of using each matrix
to build an individual character...


so, I was going to send out an address, then send a two character to
represent a hex number and use the bits to turn on or off the grid
combinations....

so, now, I think this could be done using the littlest pics, the little 4
bit jobs,
to receive the two serial words, then output to the latch(s) to turn on the
matrix,  does this make sense?


I don't know anything about the little pics, or much about the latches....

my starting point is with the big pics, and following along with app notes
and projects, I'm only a hobbiest....

thanks,


yeah, I am just trying to build a module, using the matrices, so that I can
build a larger display of undetermined size, from giant to 8 x 10,
general...

then to display something, you would send out the addresses with the latch
info,
to display characters of text or bit map-like pictures....

three common wires, ground, power, and serial....
and cheap as dirt-possible...
