If want to save development $s, you might check out the Protean Logic
TICkit -- http://www.protean-logic.com/ The module is directly
programmable in a library-centric Functional Basic, and includes ~30
libraries, including ones for LCD, direct I2C, "simulated" I2C, and I
think keypads. All lib source is included, freely downloadable, as is the
A ready-to-go module (chip, crystal, etc) is US$45/ea, and the raw chip is
$16 in singles. Development station is $36-$90, depending on how much you
want to build. I bought the $90, plus a dev board with regulator etc, and
have been *very* happy with it.
