My stamp dead or alive?

Hi Alex,
According to your previous message you were running a motor in the
application and the battery when dead or low.
The issue I see is, how much effort did you take to protect the stamp
from inductive spikes from the motor? what isolation did you provide
between the logic and the motor drive hardware? Did you use separate
power supplies, with adequate flywheel diodes in place? If this was
insufficient, you probably fried the stamp.
If you used the stamp to power anything other than the base of a
transistor you probably fried the stamp regulator. All the information
you need to get most things done is in the stamp manual and the Nuts
and Volts archieves along with some basic electronic books, have you
read this material, if not, start reading.
Alot of people have fun with stamps but some people will get in over
their head on design issues which will easily kill a stamp or any
other digital device. If this has happened to you then this simply
means that it is time to hit the books and learn, or you will probably
kill more stamps without understanding why.
We cannot see what you built or why, and thus we out here in the stamp
group will be hard pressed to give you the correct answer.

of my problem , downloading a program to the stamp with the stamp editor
results in a hardware communications failure, but alt I says the stamp is
there, so Is my stamp dead or alive? or is the stamp fine but the Rs232
Interface cooked?
Thanx
-Alex

If it helps the motors where servos of the same regultaor with flyback
diodes, but maybe the wasnt enough. Can a stamp be cooked to hell but still
be identifed by the software as being there?
Thanx again !

it says it doesn't response it means the cable or power is bad. Are you SURE
that the battery is a good 9v one?
