Hex Ser Some Question

Archiver

Dear All

Thanks for your replies. I have some more question, your replies would really be
valuable for me.

The stamp I am using gets data from one camera(input camera) and has to transmit
the information to another(output camera) after certain calculations.

Now I have conected the Input camera and it works perfectly.My question is can I
used the same serial port(#16) which I use for downloading the program in the
stamp for transmitting data to the Output camera.

I mean after downlading the program intot he stamp I disconnect the serial port
from the PC and connect it to the Output camera

Is this possible

Thanks Once again

waiting eargerly for your reply

Jimmy

Note 'Hex' may confuse some people. If you
use: SEROUT
, , [noparse][[/noparse]HEX ] then
converted to one or more hex characters
will be output.

If you just output [noparse][[/noparse] $ff ], then the one byte
containing $ff will be output, which I believe
is what you intend.

Yes, you can connect the BS2's serial
port to the 'output' camera.

Some caveats, though.
The BS2 serial port uses the attached device's
TX line to provide voltage for its RX-Out
transistor. (BS2 drives the DB-9 Rx pin,
so you can use a straight through cable).

As long as the camera you attach the
cable to is driving its TX line, this should
work. Of course, you have to match baud
rates and modes (when using BS2 built-in
serial, you need to select 'Inverted' mode)

Note also that the BS2 is a single-threaded
beast -- so it can't 'listen' to one port
while transmitting on the other. You may
have to do something to guarantee that
the 'input camera' does not talk while the
BS2 is talking to the 'output camera'.
