[[Again, for some reason this went direct to the poster, so I'm sending
it to the list... Sorry!]]

Not quite what you are looking for, but our "Basic Stamp Project of the
Month" this month is relevant. The system I show is slow and one way,
but it is cheap and readily available. A PIC could drive it much faster
(much of the slow speed is to allow for the Stamp's processing latency)
although it would never be high speed. In theory, you could adapt the
system for two way, although I haven't personally done this.

Anyway, might spur some ideas. The project of the month changes each
month and is always at: http://www.al-williams.com/awce/som.htm

We call it the Basic Stamp Project of the Month, but we occasionally do
PIC, SX, or just general-interest projects.

Good Luck!
