I think you'll find the real advantage of the project board is that it
is programmable so you can run existing PIC code modules on it and only
have to worry about writing the screen display logic.  Even this can be
simplified if you adapt PIC code for writing to LCDs.

If you are interested in reading more there was a short article in the
magazine British Amateur TV Club CQ-TV issue 194 pg 45, available from
http://www.btinternet.com/~ian.pawson/cq-tv/cq-tv194.pdf

The article describes programming the project board.
