How to use a timer function and monitor the in
One simple (maybe too simple for your application) solution:
- tie process control line low through pulldown resistor so default
state is low
- connect emergency stop switch between ground and Stamp reset pin
- when start button is pressed, drive process control line high
and start PAUSE
- if at any time emergency stop switch is activated, Stamp
program will stop, process control pin will revert to input state
and line will be pulled low--when switch deactivated, program starts
all over again

slow down the system and shut off some outputs before I can turn off
the stamp. If I would just reset the stamp I have a real emergency!!!
Big troubles if this happenes!!!!!
Thanks anyway,
