BS2SX Carrier Board Comm
Archiver
Posts: 46,084
Jim,
I have read the doc and I see where it talks about the carrier
board. It says:
The connector is wired to allow both programming and run-time serial
communication (unless you are using the Stamp2 Carrier Board which is
designed for programming).
It is talking only about the built-in serial port (SIN/SOUT - port
16). You can use ports 0-15 on the carrier board to communicate with
any device asynchronously, including a PC. What the doc is really
saying is that you can use the Basic Stamp's "special" serial port
(16) for communications as well as the "normal" ports (0-15), except
for on the Carrier Board.
You may already know this, but when connecting your BS2SX to the PC
you must have some kind of level-shifting circuit as an interface
inbetween the PC and the stamp. The PC's RS-232 port uses 12 volts
and the stamp communicates using 5 volts. The MAX232 is a great chip
that you can use for this purpose. Also, the signals from the PC are
inverted. Just so you know.
