No that's fine Andy. The problem I see is that the learning
curve is just too steep and/or long. You appear to have
very little knowledge of microcontrollers or control systems
let alone the control system safety design requirements
which are essential when designing something to detonate
explosives or fireworks. And such an area is not the place
to begin your learning process for obvious reasons - mistakes
are far too costly - and maybe not just to you either. It's a
really sweeping statement (and I _know_ I'll be flamed :) )
but I wouldn't want anyone with less than (say) 5 to 10
years experience in electronics/control design after
completing a degree to do these systems. And keep in
mind almost any system of this type will be subject to
peer review, extensive testing and probably loads of
enforceable standards it has to meet. I can only guess
that if you need to ask these questions on a newsgroup
then you don't have access to those facilities.
Start off designing such a system to operate (say) an
extended watering system for a garden - worse that
can happen then is someone gets wet :) And I'll happily
help you out by regular e-mail then if you wish.
