BS2 Reset Question
Archiver
Posts: 46,084
Good Day:
I'm looking for a simple way to remotely Reset a BS2
that is being used as a remote data gathering
terminal. I thought a menu choice could be to reset
the stamp if it's acting up. Can I use a pin to drive
a transistor to take the reset low? Any better ideas?
Thanks,
Andy Shor

Can I take the pin high via software or do I have to
actually put 5v to it?

This will be a physical reset by software.

You really need to do a bit of both....
ie. Use a Stamp I/O pin (since ATN is not such a beast) to drive ATN high if
you want the Stamp to reset itself. ATN is physically pin 3 on the BS2.
Remember that ATN is connected to the RS232 DTR via the Serial Cable to your
PC for programming, and that the Stamp Programming software uses this to
reset the BS2 before loading program tokens by pulsing ATN to +12V.
From your message it appears as if you are using a PC program to interface
to the Stamp during operation and that your PC program is the 'Master'
(since you mentioned "a Menu Option"). In which case perhaps you can pulse
the DTR pin high from within your PC program? You would have to ensure that
ATN was held at less than +1V at all other times to avoid spurious resets.
Just a few thoughts...
Regards,
Lance.

Thanks for the help. I just got the main code working
so now it's on to the "Reset" plans.....
