Coundown timer on LCD

[Bruce]

I will continue my search through the galaxy of electronics one PIC at a time, may the force be with!

Avoid planet 9 - they worship AVR, and have really ugly chicks.;o}

I am glad I can amuse you all, it is good to laugh. You have not seen the inter agency bulletins I have seen. Amazing what can be done with common objects, a little creativity, and a serious hate. I stand by my statements. Be well, do no harm, enjoy this hobby. Keep in mind this forum is Global, from Beirut to Boston, to Baghdad to Bristol. It is wise to keep in mind, the things you say here are read Everywhere. Muddy, an LCD is a DEBUGGING tool not just a display for the movies, logic would dictate it's removal in a device used for evil purposes. Oh and yes, This could be used for model rockets, Camera control, stage drag races, lots of legitimate uses, I just feel it prudent to think about, the sinister possibilities, and choose not to advance them.

So, you are saying that we should not allow anyone to learn anything that could _possibly_ have a sinister application?

Hi Kamikaze,

The application is what you do with the thing ... Even simulating fighting ( stupid video games ... or ... ) could lead 'light minded" guys to do it for real in the real life.

Hunting is just supposed to bring you food ... not adrenaline peaks.


Quite everything in this world could have a sinister application.

we just should not help if knowing the final use leads to violence ...

but how to always know ???

This is exactly my point ^^^.

I'm saying that we shouldn't withhold helping someone learn something just because it could possibly be used for a sinister application, because that would apply to almost everything.

I agree that we should not help if we _know_ that the final use is for violence, but certainly in this case, there is no reason for us to assume that that is true.

I guess I just assume the best in people unless I see evidence to the contrary. I definitely believe in innocent until proven guilty.

Hay there again, well after reading through the thread and at first feeling like i was accused of 911 myself :O and then reading peoples reactions it seems to of gone a bit far.
If i was said crazy crazy bomb bomb man i dont think i would bother with all this coding jargon. Maplins and RS and similar people (radio shack for you americans among us) proberly sell things that would be alot more reliable.

I'm an electronics apprentice and im trying to improve my background knowledge and find some intresting projects along the way. With any luck this will also be used towards my BTEC HNC at the end of next year.

Anyway back on topic and away from my dating agency advert^.

I'm going to give some of the proposed codes on here a try today and shall report back on findings although i have neverused the timer commands on pics ive always used loops adding 1 to b1 and checking values etc.

[muddy0409]

Yes, unless you need really accurate timer, then the "add 1 to b1 and check value" sort of thing would be good enough for almost any project. I personally have only had timer experience with Mel's olympic timer and modified it somewhat to count either up or down, depending on another pin's level. I still haven't really nutted out the timer function or the interrupt bizzo, 'cos I figure I can simply use the modified Mel's timer for whatever I want. I don't think I really need to know EXACTLY why/how a PIC does what it does, I just need to know that it WILL do what it does. I have picked the timer and interrupt sections out of the original and simply use them when I need to. See?, plagerism is alive and well!!
