[PIC]ICD2 does not release from reset

I have an ICD3 (R23) that will not release the target chip from reset. 
While in reset, it holds the MCLR at 0V. When releasing from reset, it 
only allows MCLR to rise to approx. 1.8 to 2.1V. I am using the 
recommended diode/resistor combo from VDD to MCLR. Does anyone have 
suggestions as to what may have failed in the ICD2 to cause this?

RE: [ADMIN]: Question about member

Can I ask everyone to drop the [ADMIN] tag from this thread please?

I am now totally bored (my personal viewpoint) with this subject and am on
the verge of blocking all admin posts.

This is NO LONGER an admin subject, and whilst Olin's behaviour may or may
not have upset someone, I am now losing the will to live.

Ok, fair enough.

I haven't been subscribing to this list very long (about a year, I think),
and so have missed the posts and flamewars being mentioned.  But I do know
of Olin's style from the Microchip forum, before he sadly (but justifiably,
in my opinion) disappeared from there.

I have never had a problem with anything that Olin has written (that I have
seen).  I have seen him being "impolite", sure - but in every case I have
thought the same myself.  For example when a student appears with an
assignment that they want done for them, often saying it's "urgent" because
it's probably due soon and they haven't done any work.  Or when, to answer
someone, I go and look at the data sheet, I do wonder why the person
couldn't have done that themselves.

I do agree that it is important to be polite, but I also agree with Olin
that when someone asks a question that, with just a little work, they could
easily answer for themselves, or if their question shows that they really
haven't considered the problem and just want an answer on a plate - that is
also rude, and arrogant.  I personally don't have a problem with the way
that Olin responds to those situations.

Perhaps I would have a problem if it was directed at me?  I don't know.  All
I can say is that I would like to see Olin feel free to contribute to both
the PIClist and the Microchip forum.

What if all the windows are open ?

Re: [EE] Car door sound detection (clapper?) [AVR] too

Honestly, I think sound detection is too problematic

How about ....

IR transmitters on the doors. Their outputs are picked up by
a centrally-located receiver. If a door opens, its transmitter
will no longer be received, as it's now pointing outside the car.
Could all be fixed in place with magnets

I respectfully suggest that you do know

And for that to happen, *something* has to change

Maybe that person just couldn't understand the data sheet. Learning to 
understand what a data sheet is trying to convey takes time. It gets 
easier with practice.

Anyway, regardless of how you may feel about someone asking a "stupid" 
question,  NO ONE is holding a gun to your head and forcing you to 
respond.

When a young kid has a tantrum in a store and the parents are ignoring it 
would you take it upon yourself to go over and slap the kid? The best way 
to deal with it is to ignore it.

Re: [ADMIN]: Question about member

> I am now losing the will to live

Hang in there Jim

I've countered "lazy and stupid" people (who actually seem to
have been fairly thin on PIClist ground for quite a while, since
they found the Microchip forums presumably), with

"How to ask questions the smart way"

http://www.catb.org/~esr/faqs/smart-questions.html

The onus is then on them to show what they've done on their
own behalf. BTW "stupid" is not a word I'd use. Often ;-)

Secondly, if the response to questions is always going to elicit
a response along the lines of "I know how to do it, how about
you **** off and read a book, or trawl the web for years so
you'll know how to do it too, or just go away and come back
when your balls have dropped", what is the point of discussion
forums ? Might just as well leave everyone to their own devices
(literally and figuratively)

I go up to parents with crying babies, yelling kids, etc. and ask  
them to take it outside.

Re: [EE] Car door sound detection (clapper?) [AVR] too

When the interior light turns on, there's an easily detectable glitch
in the 12V bus.
This has been used for car alarms since the 70's.
You can see it anywhere on the bus.

You can't easily tell it from other spikes, but then again, does it
really matter?
Engine on and off can be seen from the alternator whine and the
voltage of the 12V bus.
