Re: DRO to Serial Port Calipers

Well, you've got some options...

Courtesy of Lee Studley (indigo_red@...) who I think is still on
this list. Originally intended for a parallel interface, but later
modified for serial (stripped the parallel code out of the PIC, but
left it on the schematic). Use RX and TX from JP1.

W. Fedtke (wfedtke@...) is in Germany as I recall, and has
interfaced to a seven segmnet LED for standalone use (no PC required).
You can get pics and schematics for this from Lee (above), but no
source code.

The only one I've built to date. This was a winner in a design contest
sponsored by PCMX, who make really really nice PC Boards. I ordered
six boards (minimum order) to build these, programmed the chips, built
a board, and the computer talked to them, but I couldn't get the scale
to talk to it - kept spewing gibberish. So I stopped working on it
(ran out of time) and its been waiting for me ever since. You are on
your own with this one, as I've tried multiple tiems to comtact the
author to no avail.

You can always get something commercially made, but as I recall they
are quite expensive.



Let me know if you have any questions,
